To elucidate the regulatory effects of foliar application of micronutrients on maize yield and grain nutritional quality, a split-plot experiment was conducted with variety as the main plot factor (Zhenghuangnuo 2 and Lunuo 299) and micronutrient foliar spray as the subplot factor (Zn+Fe: 2.0% zinc sulfate heptahydrate + 2.0% ferrous sulfate heptahydrate; CK: no spray), resulting in 4 treatments in total. Ear traits, grain yield, and grain quality parameters were measured across treatments. The results showed that variety was the core factor determining ear traits, yield, and baseline grain nutritional quality of waxy maize. Zhenghuangnuo 2 exhibited superior ear diameter, kernels per row, kernels per ear, shelling percentage, and crude fat content, while Lunuo 299 had greater cob diameter, 100-kernel weight, and crude protein content. The effect of foliar spray of mixed Zn and Fe micronutrients on grain yield varied by variety. Compared with CK, the Zn+Fe treatment increased grain yield of Zhenghuangnuo 2 by 17.0%, while no significant effect was observed for Lunuo 299. The Zn+Fe treatment synergistically increased grain Zn and Fe concentrations in both varieties, with no significant effect on crude protein or crude fat content. Correlation analysis indicated that grain Zn and Fe concentrations were positively correlated (P < 0.001), while crude fat and crude protein contents were negatively correlated (P < 0.01). In summary, foliar application of mixed Zn and Fe micronutrients is an effective strategy for biofortification of Zn and Fe in waxy maize grains, and when combined with suitable varieties, it can achieve synergistic improvement in both grain yield and micronutrient content. This study provides a reference for high-quality and high-yield cultivation management of waxy maize.
To evaluate the planting performance of 3 long-grain aromatic japonica rice varieties (Xiushuixiang No. 1, Jiahexiang No. 1, and Exiang No. 2) in Tongcheng City, field plot experiments with varied sowing dates and years were carried out in the study area during 2022-2024. A total of 6 sowing dates were set over the three-year period: 2 sowing dates (June 2 and June 17) in 2022 with Xiushuixiang No. 1 and Jiahexiang No. 1; one sowing date (June 1) in 2023 with Xiushuixiang No. 1, Jiahexiang No. 1, and Exiang No. 2, with Changyou No. 5 (CK1) and Fujing No.1 (CK2) as controls; and 3 sowing dates (May 16, May 31, and July 10) in 2024 with Xiushuixiang No. 1, Jiahexiang No. 1 (not included in the July 10 sowing), and Exiang No. 2. The growth duration, panicle number, yield components, stress resistance, grain yield, and grain zinc content were systematically measured. The results showed that Xiushuixiang No. 1, Jiahexiang No. 1, and Exiang No. 2 were characterized as early-maturing late japonica, late-maturing late japonica, and medium-maturing late japonica, respectively. Average effective panicle numbers were 276.08 × 10⁴, 295.36 × 10⁴, and 269.89 × 10⁴ panicles/hm², with average grains per panicle of 141.12, 132.72, and 128.21 grains, average 1 000-grain weights of 26.78, 27.85, and 29.08 g, and average plant heights of 98.53, 100.28, and 94.58 cm, respectively. All 3 varieties exhibited strong lodging resistance and disease resistance, moderate to extreme heat and cold stress, but relatively strong low-temperature tolerance during the grain-filling stage. Average grain yields ranged from 7.48 to 7.70 t/hm². Grain zinc content were all above 15.0 mg/kg, indicating a relatively strong zinc uptake capacity. This study provides references for the planting and promotion of Xiushuixiang No. 1, Jiahexiang No. 1, and Exiang No. 2 in the study region.
To investigate the effects of soil available zinc content on the yield-increasing response of rice to zinc fertilizer application, a field experiment was conducted at 2 sites (A, with available zinc content of 0.85 mg/kg; B, with available zinc content of 1.32 mg/kg). Based on uniform application of equal amounts of base fertilizer, 3 zinc fertilizer treatments were established: no zinc fertilizer (Zn-0), application of ZnSO4·7H2O at 15 kg/hm2 (Zn-1), and application at 30 kg/hm2 (Zn-2). The growth and development, grain yield, and output value of rice under different treatments were measured. The results showed that the effects of zinc fertilizer application on rice growth and yield varied significantly depending on the initial available zinc content of the soil. At site A, compared with Zn-0, the Zn-1 and Zn-2 treatments increased plant height, effective panicle number, panicle length, seed-setting rate, and 1 000-grain weight. The grain yields under Zn-1 and Zn-2 were 9 285 and 9 060 kg/hm2, respectively, representing increases of 11.3% and 8.6% over Zn-0. The Zn-1 treatment achieved the highest agronomic efficiency of zinc fertilizer and the highest output-to-input ratio, at 63.0 kg/kg and 16.64, respectively. At site B, zinc fertilizer application had no significant effect on rice growth traits, and grain yields under Zn-1 and Zn-2 were 8 235 and 8 040 kg/hm2, representing decreases of 2.1% and 4.5%, respectively, compared with Zn-0. In conclusion, in fields with low soil available zinc content, appropriate application of zinc fertilizer (15 kg/hm2) can promote nutrient uptake, increase grain yield, and improve economic benefits in rice production.
To investigate the effects of small-molecule peptide organic water-soluble fertilizer on the growth and yield of cherry tomato, this experiment was conducted using the cultivar ‘Qingxia 66’. The base fertilizer was kept uniform across all treatments, and topdressing was applied in three splits: at the initial budding stage, fruit expansion stage, and full fruiting stage. The topdressing regimes for each treatment were as follows: treatment 1 received small-molecule peptide organic water-soluble fertilizer at 12, 30, and 30 kg/667 m2 at the three stages, respectively; treatment 2 received small-molecule peptide organic water-soluble fertilizer at 15.0, 37.5, and 37.5 kg/667 m2; treatment 3 received small-molecule peptide organic water-soluble fertilizer at 18, 45, and 45 kg/667 m2; treatment 4 received small-molecule peptide organic water-soluble fertilizer at 7.50, 18.75, and 18.75 kg/667 m2, combined with macro-element water-soluble fertilizer at 1.0, 2.5, and 2.5 kg/667 m2 at each respective stage; and treatment 5 (CK) received macro-element water-soluble fertilizer at 2, 5, and 5 kg/667 m2 at the three stages. The effects of each treatment on plant traits, early maturity, fruit quality, yield, and economic characteristics of cherry tomato were evaluated. The results showed that treatment 3 exhibited the best performance in plant height (162.7 cm), plant spread (58.8 cm), and maximum leaf width (29.5 cm); treatment 2 had the longest maximum leaf length (40.5 cm); and treatment 1 had the thickest stem diameter (0.83 cm). The difference in the node position of the first inflorescence among treatments was small, the fruit color-turning period was consistent across treatments, and no significant differences in early maturity were observed. The soluble solids content in treatments 2, 3, and 4 was 0.7-1.2 percentage points higher than that in treatment 5 (P < 0.05), while differences in vitamin C content were small. The yields of treatments 1-4 ranged from 1 755.4 to 2 004.0 kg/667 m2, representing increases of 5.7%-20.6% over CK, with treatment 3 achieving the highest yield. Economic benefits were relatively better in treatments 3 and 4. In summary, topdressing with small-molecule peptide organic water-soluble fertilizer can promote vegetative growth, improve fruit quality, and increase yield of cherry tomato, with the regime of 18, 45, and 45 kg/667 m2 at the three respective stages demonstrating the most favorable effects.
This paper systematically summarized the characteristic cultivation model of in-field fresh-keeping for greenhouse autumn-extended peppers in Hexian, Anhui Province, along with green prevention and control technology. In terms of cultivation techniques, the key practices include selecting disease-resistant and high-yielding varieties, sterilizing seeds and substrates, implementing high-temperature solarization for soil improvement, cultivating robust seedlings with appropriate transplanting schedules, precisely managing temperature, fertilization, and irrigation, and coordinating plant population regulation. In terms of green pest management, an integrated technical system has been developed that combines the selection of disease-resistant varieties, seed and substrate disinfection, pesticide-treated transplanting, crop rotation, physical barriers (insect-proof nets and yellow sticky traps), release of natural enemies, and the application of highly effective, low-toxicity pesticides. This system enables effective control of major diseases and pests, including pepper Phytophthora blight, anthracnose, gray mold, viral diseases, aphids, and whiteflies. Through the integrated application of these technologies, in-field preservation cultivation is achieved, which significantly extends the supply period of greenhouse‑grown peppers. This article provides a reference for the promotion and application of this technical system.
Based on the ecological characteristics and peanut production practices in the Huang-Huai-Hai region, this study integrated key technologies, including variety selection, soil improvement and precision sowing, water and fertilizer regulation, disease and pest control, stress tolerance and disaster mitigation, and timely harvesting. Variety selection was tailored to ecological conditions: in plain waterlogged areas, large- to medium-pod varieties with waterlogging tolerance and lodging resistance were selected; in hilly dryland areas, medium- to small-pod varieties with drought tolerance were selected; and in summer direct-seeding areas, early-maturing and dense-planting tolerant varieties were required. For tillage practices, a soil cultivation model combining deep tillage with rotary tillage was adopted, along with cultivation methods such as ridging with plastic film mulching, to establish an optimal canopy structure. Water and fertilizer management was implemented based on the growth-stage requirements of peanut, with graded application of base fertilizer and topdressing, combined with drip irrigation under plastic film to achieve precise water regulation. For disease, pest and weed control, integrated approaches including resistant varieties, physical and chemical lures, and biological control were comprehensively applied.Followed by chemical control at the 2-5 leaf stage for both grasses and broadleaf weeds. Fungicides such as pyraclostrobin·epoxiconazole and flutolanil were applied at appropriate times to control leaf spot and southern blight, while insecticides including spinetoram and abamectin were used to control thrips and spider mites. Differentiated measures were adopted for different stress conditions: in waterlogged fields, timely cultivation was carried out to promote soil aeration and moisture dissipation; under low-temperature conditions, foliar spraying of calcium nitrate and potassium dihydrogen phosphate was applied, combined with plastic film mulching; and in continuous cropping fields, lime nitrogen (calcium cyanamide) was recommended for soil disinfection. Harvesting was conducted when pod moisture content fell below 25%, followed by timely sun-drying or mechanical drying, and storage under low-temperature and dry conditions (temperature < 20 ℃ and relative humidity < 65%). This paper provides a reference for high-yield and high-efficiency peanut cultivation in the region.
This study systematically conducted cutting propagation experiments on native tea plant germplasm resources in Bijie, investigated the effects of hormone treatments (A1, 120 mg/L IBA + 35 mg/L NAA soaking for 12 h; A2, 100 mg/L ABT No. 1 rooting powder quick-dip for 10 s; A3, 500 mg/L ABT No. 1 rooting powder soaking for 30 min; A4, water control), substrate ratios (B1, yellow soil:vermiculite = 4 :1; B2, yellow soil:rock debris = 4:1; B3,pure yellow clay), and geographic origins (5 representative tea-producing counties/districts with tea plant germplasm resources were sampled: C1, at an altitude of 1 500–1 600 m, with mother plant ages of 40–50 years; C2, at an altitude of 1 400–1 800 m, with mother plant ages of 20–40 years; C3, at an altitude of 800–850 m, with mother plant ages of over 100 years; C4, at an altitude of 1 600–2 300 m, with mother plant ages of 15–30 years; and C5, at an altitude of 2 400–2 700 m, with mother plant ages of 10–35 years) on the cutting performance of tea cuttings. The results showed that significant differences were observed in cutting traits among native tea cuttings from different sampling sites, and the optimal hormone treatment and substrate ratio varied with the cuttings. Ancient tea germplasm from sampling sites C3 and C4 exhibited better adaptability, with survival rates of 96.7% and 91.5%, and rooting rates of 97.5% and 92.8%, respectively, under the A1B1 treatment. The C3-A1B1 treatment resulted in better root development, with 9.7 roots ≥3 cm in length, a maximum root length of 12.3 cm, and a root fresh weight of 0.86 g, and the roots displayed a radially dense distribution pattern. This paper provides a reference for the breeding of new Guizhou tea series varieties and their industrial promotion.
To investigate the effects of the burial depth of salt barrier layer on apple growth in coastal saline-alkali land orchards, this study used 5-year-old ‘Yanfu 3’ apple as the experimental material. A control group (CK) without setting a salt barrier layer was set up, and 3 salt barrier layer depths of 20 (T20), 40 (T40), and 60 cm (T60) were set. The distribution of soil salt content, total root length, root surface area and other root system morphology, tree height, trunk circumference and other growth indicators, as well as yield and soluble solids and other quality indicators were measured under different treatments. The results showed that the salt barrier treatment effectively inhibited the upward movement of soil salt and improved the root zone environment. Among them, the T40 treatment had the best effect. The roots were mainly distributed in the 0-40 cm soil layer, and the root length density and root surface area were significantly higher than those of the other treatments; under this treatment, the growth of new shoots was the greatest, reaching 41.5 cm; the single plant yield was 28.6 kg, which was 18.67% higher than CK; the soluble solids content of the fruit, fruit hardness and color index were the highest, respectively 15.8%, 8.6 kg/cm² and 0.89. Overall, setting a 40 cm salt barrier layer in the coastal saline-alkali land orchard can effectively optimize the root distribution, promote the increase in apple yield and quality, and has good application value for promotion.
Forestry pest monitoring and forecasting are of great significance for ensuring regional forestry ecological security. This study took Sihui City, Guangdong Province as the research object, systematically reviewed the current status of forestry pest monitoring and forecasting in this area, analyzed the aspects that needed improvement, and proposed corresponding countermeasures. At the time of the study, the research area has adopted a comprehensive monitoring approach that combined zoned fixed-point monitoring, trap luring, insect light traps, manual ground surveys, and UAV aerial photography. However, the monitoring network and infrastructure, grassroots technical personnel allocation, quarantine enforcement, and financial investment still required strengthening. Based on this, an integrated monitoring network is constructed, which integrated ground surveys, UAV patrols, and satellite remote sensing, combined with species distribution models to predict suitable habitats for pests. In addition, technical team building is enhanced through talent introduction and regular professional training; quarantine work is improved by implementing closed-loop management covering transport, planting, and nursery stages; and financial investment is increased, with the introduction of socialized services and the upgrading of monitoring equipment. This study provides a reference for the precise prevention and control of forestry pests.
To explore the aesthetic characteristics of formal terraced garden landscapes, this article systematically reviewed its core gardening elements and conducted an analysis by combining classic estate cases from different development stages. In formal terraced garden landscapes, common plants such as Pinus pinea, Olea europaea, and Laurus nobilis are often used to create distinctive plant landscapes featuring green sculptures and green buildings. The forms, locations, and functional values of water features are fully exploited to construct rich water landscapes such as cascades, wall fountains, and water jets. The overall layout of sculptures is balanced and symmetrical. Most buildings are located on the central axis, serving as the main visual focal point of the entire garden. The early manor adopts a geometrically symmetrical layout. The windows of the building are small, and it is complemented by a battlement-style roof, presenting a spacious, bright and open spatial characteristic. The mid-term manor adopts the rule-based landscape design, creating one main axis and two secondary axes, and processing the water in a three-dimensional manner. Through the combination of water features and sculptures, it enhances the atmosphere of the landscape. The late manor applies the perspective rule, using one main axis to sequentially connect the entrance square, the tree-lined avenue, the fountain square, and the main building and other important nodes, forming a complete space. This article provides a reference for the construction of contemporary garden landscapes.
To improve the quality of atmospheric environment monitoring, this study systematically analyzed the key factors affecting monitoring performance and proposed targeted optimization pathways. At present, the quality of atmospheric environment monitoring is affected by several core factors, including the precision of monitoring technologies, the rationality of site layout, equipment stability, and the availability of professional personnel. Accordingly, the following optimization strategies are proposed: introducing advanced technologies such as lidar and satellite remote sensing to construct an integrated “space–air–ground” multi-source data fusion monitoring system; dynamically optimizing the layout of monitoring stations based on the CALPUFF atmospheric dispersion model to enhance the accuracy of pollution source tracing; establishing a whole-life-cycle equipment management mechanism to ensure the accuracy and continuity of monitoring data; and building a multi-level professional talent cultivation system to strengthen the technical capacity of monitoring teams. This study provides a reference for the optimization of atmospheric environment monitoring networks and the precise control of agricultural non-point source pollution.
This paper reviewed the current status of crop straw resource utilization in Zhangjiagang City, Jiangsu Province, analyzed the key factors constraining the improvement of comprehensive straw utilization, and proposed optimization strategies accordingly. The study area has a large quantity of collectable straw resources, with mechanized incorporation into farmland accounting for a relatively high proportion of the comprehensive utilization pathways, while off-field utilization is primarily dominated by fertilizer, energy, and substrate applications. A market-oriented collection-storage-transportation system covering major agricultural towns has been preliminarily established. However, the current straw utilization still requires improvement in terms of utilization models, collection-storage-transportation systems, and support mechanisms. On this basis, the following optimization strategies are proposed. First, innovate diversified utilization models by improving supporting technologies for straw incorporation while actively cultivating diversified utilization industries such as feed, substrate, and energy applications. Second, improve the collection-storage-transportation system by constructing an industrial chain of “enterprises + cooperatives + farmers” and improving a regional supply-demand information coordination network. Third, improve the support system by increasing subsidies, land use guarantees, technology promotion, and publicity guidance, so as to promote the formation of a sustainable market-oriented mechanism for comprehensive straw utilization. This study provides a reference for promoting straw resource utilization in the locality and similar county-level regions.
This study analyzed the variation characteristics of fine particulate concentration and sources using backward trajectory clustering, potential source contribution factor (PSCF), and concentration-weighted trajectory (CWT) methods, based on meteorological and particulate pollution observation data for PM1, PM2.5, and PM10 from July 31, 2018, to May 8, 2022. The results showed that daily PM1 concentrations in the study area fluctuated greatly in winter and summer and remained stable in other seasons. PM2.5 concentrations were steady across all 4 seasons, while daily PM10 concentrations fluctuated obviously in winter and spring. Backward trajectory analysis, together with PSCF and CWT analyses of typical pollution episodes, indicated that winter PM1 pollution was mainly influenced by short-distance heavily polluted air masses from SH and NJ, as well as medium-range air mass transport from HB, JX and HN. This study provides a reference for the analysis of fine particulate pollution characteristics in similar regions.
To investigate the spectral characteristics of tobacco-planting soils in Shilin Yi Autonomous County, Yunnan Province, and their application in soil classification, this study collected 409 topsoil samples from 7 regions within the study area. Mid-infrared (700–4 000 cm-1) attenuated total reflection spectra were measured, and analytical methods including principal component analysis (PCA), hierarchical clustering, and probabilistic neural network (PNN) were employed to explore soil heterogeneity at the county scale. The results showed that the soil spectra exhibited characteristic kaolinite doublets at 3 693 and 3 619 cm-1, while a broad peak at 3 440 cm-1 indicated contributions from organic matter hydroxyl groups. Both PCA and hierarchical clustering confirmed the spatial heterogeneity of soil spectra among the 7 regions, though high similarity in some areas made spectral differentiation challenging. Based on these findings, the 7 regions were consolidated into 4 a priori categories, and a four-class PNN classification model was constructed, achieving an overall recognition accuracy of 88.5%. Collectively, the results demonstrated that mid-infrared spectroscopy can effectively identify spatial heterogeneity characteristics of tobacco-planting soils in the study area and achieve classification with high accuracy, providing a reference for precision management in tobacco production.
From 2022 to 2023, this research conducted a systematic investigation of the annual occurrence dynamics of 6 Lepidopteran pests (including Phyllonorycter ringoniella, Helicoverpa armigera, Cydia pomonella, Grapholitha funebrana, Spodoptera litura, and Hyphantria cunea) in the peach variety orchard of Institute of Fruit and Floriculture Research, Gansu Academy of Agricultural Sciences using sex attractant trapping monitoring technology. The results showed that, Phyllonorycter ringoniella was captured 462 times in 2022 and 588 times in 2023. It was the dominant species among the Lepidopteran pests in peach orchard. The annual capture rate of Helicoverpa armigera ranged from 32 to 41 individuals, that of Cydia pomonella from 10 to 14 individuals, and that of Grapholitha funebrana from 6 to 7 individuals. They were occasional pests. During the entire growth cycle of peach trees, the occurrence period of Phyllonorycter ringoniella is long and its population is large. The overwintering adult stage of Helicoverpa armigera emerges successively in late March, causing damage to peach tree leaves in the early stage and then moving to other host plants for feeding. Cydia pomonella and Grapholitha funebrana have no obvious peak occurrence periods in the peach orchard and were considered accidental pests; Hyphantria cunea has sporadically occurred in the peach orchards. This article provides a reference for the control of Lepidopteran pests in the relevant areas.
To explore the control efficacy of radio-frequency technology against Ephestia elutella in the tobacco threshing-redrying process, the thermal tolerance of Ephestia elutella and Lasioderma serricorne was compared. Based on the thermal death kinetics of more heat-tolerant Lasioderma serricorne larvae, key radio-frequency insecticidal parameters including heating temperature, holding time, upper-lower plate spacing and tobacco-leaf thickness were determined. The lethal effects on eggs and larvae of Ephestia elutella, chemical quality (total alkaloids, reducing sugars, total sugars, etc.) and smoking quality (strength, aroma quality, offensive odor, etc.) of tobacco leaves under radio frequency treatment were determinated. The results showed that under the heating temperature-time combinations of 53 ℃-20 min, 55 ℃-5 min and 57 ℃-1 min, Ephestia elutella exhibited lower heat tolerance than Lasioderma serricorne. The larval mortality of Lasioderma serricorne reached 100% when treated with a heating plate at 55 ℃ for 2 min. The heating uniformity remained relatively stable with the radio-frequency upper-lower plate spacing of 110 mm and tobacco-leaf thickness of 60 mm. When treated by radio-frequency at 57 ℃ for 2 min, both eggs and larvae of Ephestia elutella achieved 100% mortality. Radio-frequency treatment exerted no adverse effects on chemical components and sensory quality of tobacco leaves. In conclusion, radio-frequency technology can be applied to control Ephestia elutella during the tobacco threshing-redrying production process.
To explore the effects of the time of pollen from the paternal and maternal parents on the fruit setting rate and the characteristics of the capsules in the hybridization of Dendrobium species, this study conducted an interspecific hybridization experiment using Dendrobium Cassiope × moniliforme as the maternal parent and Dendrobium ‘Red Star’ as the paternal parent. Artificial pollination was carried out at different times after the flowering of the parents (on the 1st, 6th, 11th, 16th, 21st, and 26th days of flowering), and the fruit setting rate, longitudinal diameter, transverse diameter of the capsules, and fruit stalk length were measured. The results showed that the capsules with the largest longitudinal and transverse diameters were obtained by cross-pollination using pollen collected on the first day of flowering of the paternal plant Dendrobium ‘Red Star’. However, the fruit setting rate was relatively low, at 66.67%. The fruit setting rate was above 95% from the 6th to 11th day after flowering. On the first day of flowering of the maternal plant Dendrobium Cassiope × moniliforme, the capsules with the largest longitudinal diameter were obtained through pollination and hybridization, but the fruit setting rate was relatively low, at 63.33%. The fruit setting rate reached 100% on the 6th day of flowering, and the longitudinal and transverse diameters of the capsules were at a medium to upper level. Additionally, the length of the fruit stalk was superior to that of other groups. Overall, if the goal is to obtain the largest fruit, both the parent plants should be pollinated on the first day of flowering. If both high fruit setting rate and excellent fruit traits are considered, the paternal plant can be pollinated on the 6th to 11th day of flowering; the maternal plant should be pollinated on 6th of flowering. If the pollination time is the latest, the maternal plant needs to complete the hybridization within 21th of flowering and the paternal plant within 16th of flowering to ensure a certain fruit setting rate. This study determined the optimal and latest pollination times for Dendrobium Cassiope × moniliforme × Dendrobium ‘Red Star’ hybrid combination, providing a reference for the arrangement of parent flower periods in the hybrid breeding of Dendrobium.
Hainan possessed abundant germplasm resources of tropical rare and superior fruit trees, which constituted an important component of regional characteristic and high-efficiency agriculture. This paper reviewed the current status of exploitation and utilization of these fruit resources in Hainan, analyzed the links that remained to be improved in industrial development, and proposed targeted countermeasures. The planting scale of rare and superior fruit trees in the study area continued to expand, with steady increases in both planting area and yield for durian, rambutan, jackfruit, and pitaya. Notable achievements were made in variety breeding, with a total of 173 applications for new plant variety rights filed over the past three years. Market benefits were prominent, and initial progress was observed in the integration of agriculture with tourism as well as in industry-university-research collaboration. However, there remained room for improvement in the degree of resource exploitation and utilization, supporting technical systems, industrial chain extension, collaboration mechanisms, and brand marketing. Based on these findings, countermeasures were proposed, including enhancing the exploitation and utilization of resources, improving the supporting technical systems, promoting industrial chain extension and value addition, deepening industry-university-research collaboration, and strengthening brand building and market promotion. This paper provides a reference for the high-quality development of the rare and superior fruit industry in Hainan.
This study was based on the comparative observational meteorological data from inside and outside greenhouses during 2019—2020, as well as the ground observation data from the national basic meteorological station. A total of 500 sample sets were selected as the training sample set, and a BP neural network prediction model was developed. The model employed outdoor daily maximum temperature, daily minimum temperature, and sky conditions as input variables, and indoor daily mean, maximum, and minimum temperatures as output variables, aiming to forecast the key temperature indices within plastic greenhouses. The model performance was assessed using the root mean square error (RMSE). Significant positive correlations (P<0.01) were identified between indoor and outdoor temperatures across all three indices. A model with a topological structure of 3 (input layer: daily maximum temperature, daily minimum temperature, and sky conditions outside the greenhouse)-4 (hidden layer: H1, H2, H3, H4)-3 (output layer: daily mean temperature, daily maximum temperature, and daily minimum temperature inside the greenhouse) was constructed. During the model training and validation, the coefficients of determination for the daily mean, maximum, and minimum temperatures inside the greenhouse were 0.987, 0.959, and 0.992, respectively, and the corresponding RMSE values were 0.96, 1.61, and 0.75 ℃, respectively. These results indicate that the proposed model is capable of meeting the practical demands of agrometeorological services in facility agriculture. This article provides a reference for temperature control in plastic greenhouses.
This study, based on tea production data in Taishun County from 2012 to 2024, combined with 5 meteorological factor datasets (including monthly average temperature and monthly average minimum temperature) from the national basic weather station during the pre-harvest period, employed SPSS software to fit 10 curve models, such as logarithmic curve model and inverse curve models, to analyze the correlation between meteorological factors and tea production, and subsequently constructed corresponding analytical models. The results indicated that the relationship between monthly average temperature and tea production followed a cubic function (P = 0.021), with the fitted equation y =-0.93 +176.45xa －126.13; the relationship between monthly average minimum temperature and tea production followed a power function (P = 0.470), with the fitted equation y = 742.9 ; the relationship between monthly total precipitation and tea production followed a quadratic function (P = 0.541), with the fitted equation y = -0.006 +0.87xc +752.58; the relationship between monthly average relative humidity and tea production followed a logarithmic function (P = 0.285), with the fitted equation y = 1 767.09－226.82log(xd ); and the relationship between monthly total sunshine hours and tea production followed an S-shaped curve (P=0.121), with the fitted equation y = exp(6.69 - 3.46/xe). This study preliminarily investigates the relationship between tea yield and pre-plucking meteorological factors, which may serve as a reference for future model refinement.
Based on the monthly meteorological observation data of average temperature, precipitation, relative humidity, and wind speed from from 2005 to 2024 provided by the Ankang Meteorological Bureau, this study analyzed the agritourism meteorological conditions of the region. On this basis, a comprehensive climate comfort index model was constructed to evaluate the agritourism climate comfort level in the study area. The results showed that the study area had an annual average temperature of 15.1 ℃, annual precipitation of 956.8 mm, annual average relative humidity of 75.6%, and annual average wind speed of 1.3 m/s, demonstrating a generally favorable climate suitable for the growth of characteristic agricultural products such as selenium-enriched tea, silkworm mulberry, and traditional Chinese medicinal herbs. The comprehensive climate comfort calculation revealed that the climate comfort index were 1.1~3.2, below 4.55 from May to September, indicating the most comfortable period for human sensation. This period coincides with key phenological stages including spring tea plucking and autumn medicinal herb harvesting, making it particularly suitable for agritourism activities. This study provides a reference for promoting the sustainable development of tourism in the study area.
This study took the Southeastern coastal area of Jiangsu Province as the research object. By using the wind effect index and human comfort index, and employing one-variable linear trend estimation and the Mann-Kendall non-parametric change point test, it conducted a quantitative assessment of the temporal and spatial changes and distribution of climate comfort in this region from 1991 to 2024. The results showed that, (1) for the entire year, the wind effect index in the study area followed a “U” shape, while the human comfort index showed an inverted “U” shape distribution; both indices reached their lowest values in winter and their peak values in summer. (2) The inter-annual fluctuation patterns of the wind effect index and the human comfort index from 1991 to 2024 were similar. They showed a linear upward trend from the cold and cool intervals. From 2003 to 2024, this upward trend passed the significance test at the 0.05 level. Both types of indices did not undergo any significant changes over the 34-year period. Among them, the human perceived temperature was the highest in 2017, and it was the coolest in 1993. (3) Throughout the year, the study area did not experience extremely hot weather. The proportion of days with a comfortable or better body sensation exceeded 50%. The months of May to October were considered comfortable periods, among which June and September were the more comfortable months. This study provides a reference for the evaluation of human living climate comfort and meteorological forecasting in related regions.
Based on the planting practices in typical hilly tobacco-growing areas of central Jiangxi Province, this paper analyzed the aspects requiring improvement in the integrated development of agricultural machinery and agronomy, and summarized its practical pathways and outcomes. The integration of tobacco agricultural machinery and agronomy requires the collaborative efforts of “optimal machinery, optimal methods, optimal fields, and optimal systems”. The study area needs improvement in agricultural machinery equipment, agronomic processes, farmland infrastructure, and socialized services. To address these issues, the following integrated development practices were implemented: in terms of machinery, a strategy of “introduction–modification–development” was adopted, introducing small and medium-sized specialized machines while retrofitting older film-mulching machines and ridging-cultivating equipment for improved adaptability. In terms of agronomy, standardized seedling raising and robust seedling criteria were unified, with the transplanting well-hole depth adjusted to 15 cm, supplemented by a soil-block transplanting device. In terms of farmland, terraced transformation was implemented on plots with slopes above 6°, accompanied by the improvement of field roads, field-access ramps, and irrigation and drainage systems. In terms of services, a three-tier network of “county-level service centers + township service stations + cooperatives” was established, with unmanned aerial vehicle (UAV) application for plant protection and preliminary tobacco grading included in the subsidy scope. Practice has shown that from 2022 to 2024, the demonstration area achieved full mechanization in the land preparation and ridging stages, resulting in reduced labor input and production costs, and an increased proportion of first-class tobacco leaves. This paper provides practical references for the integrated development of agricultural machinery and agronomy in similar tobacco-growing regions.
This paper analyzed the water-saving irrigation technical system and its application scenarios under the integration of drip irrigation, sprinkler irrigation and smart management. The water-saving irrigation technical system comprises 2 core technologies (drip irrigation and sprinkler irrigation), a smart management platform, as well as the system for technical coordination and integration. Through establishing stable water-potential gradients, drip irrigation utilizes soil matric potential to drive directional water transport in the crop root-zone soil. Sprinkler irrigation sprays water onto plants in the form of water mist or water droplets by sprinkler heads. Relying on modern scientific and technological means such as sensors and automatic control systems, information-based management systems conduct real-time monitoring and regulation of farmlands combined with water-saving modes of drip irrigation and sprinkler irrigation. Water-saving irrigation technologies possess synergistic advantages in improving water-use efficiency, optimizing farmland ecological environment, and promoting crop root development and growth. In terms of application, shallow-buried drip irrigation and mulch-film drip irrigation are adopted in semi-arid and arid regions respectively, which can improve irrigation-water use efficiency and reduce water evaporation. In hilly areas, the irrigation patterns of sprinkler irrigation for farmland, micro-irrigation for greenhouses and drip irrigation for orchards have been formed, and appropriate irrigation modes can be selected according to planting types. The application of fixed or semi-fixed sprinkler irrigation in large-scale farmlands can reduce irrigation water consumption and improve crop yield. This paper provides a reference for the efficient application of agricultural irrigation technologies.
This paper focused on UAV remote sensing technology, with an emphasis on analyzing its platform types and sensor configurations, technical advantages and characteristics, as well as its specific applications in agricultural fields such as crop identification, growth monitoring, pest and disease detection, and yield estimation. UAV remote sensing platforms include fixedwing UAVs, multirotor UAVs; sensor types include multispectral cameras, hyperspectral cameras, LiDAR, thermalinfrared cameras, visiblelight cameras, etc. With the coordination of platforms and sensors, the system responds rapidly and deploys flexibly, supporting diverse takeoff and landing methods and recovery modes, enabling rapid deployment to target areas for monitoring. The integration of multi-source sensors and real-time processing enables the acquisition of high-resolution spectral imagery and farmland spatial information. Specific agricultural applications of UAV remote sensing include: precise crop identification by fusing spectral, textural, and spatial features, combined with object-oriented classification or improved deep learning models to achieve high-precision automatic recognition of crop types; crop growth monitoring by calculating indices such as NDVI from multispectral imagery, combined with SVM, random forest, and other models to achieve quantitative assessment of crop growth status; pest and disease detection based on thermal infrared and multispectral imagery through threshold segmentation, feature extraction, and machine learning classification to achieve early detection and assessment of diseases; and yield estimation through extracting vegetation indices and texture features from multispectral imagery combined with machine learning to construct predictive models. This paper provides a reference for the development and application of UAV remote sensing technology in agriculture.
This study analyzed the application and operation status and causes of non-standard operations of plant protection unmanned aerial vehicle (UAV) in mountainous areas of Nanzhao County, Henan Province, and proposed countermeasures for further application. Several problems concerning spray liquid dosage, pesticide tank-mixing operation, operation area statistics and aerial spraying operation parameters emerge during large-scale application, exerting certain impacts on the application and promotion of plant protection UAV aerial application and the control effect of diseases and pests. The primary contributing factors for these issues are summarized as follows: UAV operators reduce spray-liquid dosage to improve aerial application efficiency; full-process dynamic field supervision is difficult to implement, which restricts the standardized management of pesticide tank‑mixing operations; scattered farmlands in the study area result in frequent relocation. Limited single-mission endurance of plant-protection UAVs compels operators to adjust operation modes for larger working coverage; operators adopt high-altitude and high-speed flight modes to evade obstacles such as overhead power lines and lower operational complexity. Accordingly, countermeasures are proposed, including balancing aerial application efficiency and pest control efficacy, establishing reasonable pricing standards, optimizing pesticide mixing management and industrial credit system, standardizing UAV operations via area verification and encouraging public supervision, as well as constructing a public intelligent supervision platform to guarantee transparent and compliant operations. This research provides references for the application and promotion of plant protection UAVs.
To address the aspects of teaching content, teaching methods, and assessment evaluation in the Landscape Ecology course that were in need of optimization, this paper, based on the OBE concept, conducted a teaching reform practice from 3 aspects: the course knowledge system and teaching content, the teaching model, and assessment evaluation. The reform was based on a three-tier progressive course knowledge framework, and the teaching content was reorganized into 3 modules: basic knowledge, core issues, and ability objectives. A mixed teaching model combining 24 hours of theoretical lectures with 8 hours of flipped classroom seminars was adopted, supplemented by 8 hours of practical teaching to strengthen the integration of theory and practice. Meanwhile, a diversified evaluation system was constructed, including pre-class online learning, after-class assignments, flipped classroom group tasks, and a final open-book examination. The reform practice, involving 167 Landscape Architecture students of the 2021 and 2022 cohorts, showed that this model effectively improved students’ learning initiative, practical application ability, and overall academic performance. 5 teaching cases were developed, and the course was rated as a “reliable course” at the university level. A questionnaire survey indicated that nearly 90% of the students recognized the effectiveness of the reform. This paper provides a reference for the teaching optimization of landscape ecology-related courses.
To align with the demands of fishery modernization, this paper systematically elaborated on the reform of the training model for master’s degree students in agricultural engineering, taking the Liaoning Donggang (Gushan) Clam science and technology backyard as a case study. The agricultural engineering master’s program at this university featured marine and fishery equipment engineering. Aiming at the issues of insufficient industrial practice environment, weak knowledge integration ability, and incomplete collaborative education mechanisms, a training model based on the science and technology backyard was constructed. This model focused on three major goals: improving engineering literacy, systematizing the knowledge system, and strengthening innovative practical abilities. Through measures such as creating an industrial practice environment, developing case-oriented courses, establishing multidisciplinary supervisory teams, and organizing comprehensive practical training, it systematically advanced reforms in curriculum teaching, practical instruction, and supervisor team development. At the operational level, reform initiatives were implemented from 3 dimensions: ideological and political guidance, practical platform construction, and supervisory team collaboration. Ideological and political education and labor education were integrated throughout the entire talent cultivation process to enhance graduate students’ local identity and industry responsibility. The Science and Technology Backyard and school-enterprise joint training mechanisms were strengthened, combining case-based teaching and academic competitions to improve students’ engineering literacy and innovation capabilities. A joint “university-enterprise” supervisory team was formed, and collaborative education mechanisms were refined to promote multidisciplinary cooperative guidance. This paper provides a reference for agricultural engineering postgraduate education to serve industrial demands.

Since its implementation in 2022, the course cultivated a total of 82 postgraduates over 3 cohorts, was awarded as a university-level characteristic course for professional degrees, and incubated multiple awards in innovation and entrepreneurship competitions. Students’ theoretical examination scores all exceeded 85 points, and the average scores of teaching evaluations across all dimensions ranged from 4.85 to 5.00 (out of 5.00). The course achieved the goals of integrating theory with practice and aligning talent cultivation with industrial demands. This paper provides a reference for the curriculum reform of professional degree postgraduates in the field of aquaculture.
In response to the problems of broad and deep teaching content, conventional lecture-based teaching methods, overemphasis on final written examinations, and insufficient integration of ideological and political education in the Genetics course for the Biological Science major, this paper proposed and implemented the BOPPPS blended teaching reform based on the weizhujiao platform. The reform was carried out from 4 dimensions: teaching content restructuring, teaching model construction, assessment system optimization, and ideological and political element mining. The original 12 chapters were integrated into 4 major modules-structure of genetic material, transmission of genetic material, evolution of genetic material, and special topics-with enhanced logical progression and case integration. Relying on the weizhujiao platform, BOPPPS teaching was implemented through 3 stages (pre-class, in-class, and post-class), forming a closed-loop blended teaching model. The assessment system was adjusted to 35% online evaluation, 15% offline evaluation, and 50% final examination, with the proportion of subjective questions increased from 30% to 50%, emphasizing comprehensive application ability. Meanwhile, teachers’ ideological and political literacy was strengthened, and cutting-edge cases and ideological elements were incorporated. Practice showed that the course objective achievement degree increased from 0.695 to 0.827, the average student score reached 71.21, and the comprehensive teaching quality score was 98.4. The teaching team obtained a total of 5 provincial and university-level teaching reform and curriculum construction projects. This model effectively mobilized students’ learning initiative and enhanced their innovation and practical abilities. This paper provides a reference for teaching reform of Genetics course in similar institutions.
Focusing on the goal of improving the quality of applied seed industry talent cultivation under the background of professional accreditation, this paper systematically analyzed the coordination of the curriculum system, the teaching participation of young teachers, and the depth of industry-education integration in the Seed Science and Engineering major, and proposed targeted countermeasures.

A high-level applied teaching team composed mainly of doctoral degree holders was established, over 20 industry experts were employed to form a dual-qualified teaching team. This paper provides a reference for the professional development and reform of similar agricultural and forestry institutions.
This study analyzed the deficiencies in the psychological education work of counselors in agricultural vocational colleges and proposed corresponding improvement strategies. The psychological education work in such colleges needs further optimization in terms of the matching degree of counselors’ disciplinary background and professional literacy, psychological education modes, and external work coordination. Targeted improvement strategies are put forward as follows: carrying out targeted independent learning of mental health knowledge and improving counselors’ abilities to identify, intervene in, and communicate about psychological problems through practical training; designing education content in accordance with students’ actual needs, fully exploiting the advantages of agriculture-related majors, and deeply integrating psychological education with professional training, campus cultural activities and other characteristic agricultural education practices; sorting out daily work in a classified manner to distinguish core work from routine administrative affairs, and learning efficient and practical psychological counseling skills by making full use of fragmented time. The strategies can effectively improve the working efficiency of counselors’ psychological education and provide a reference for the development of psychological education in agricultural vocational colleges.
Taking 18 modern agricultural industrial parks in Lu’an City, Anhui Province as the research subjects, this paper systematically analyzed their development status and challenges, and proposed corresponding strategies. The study area has clustered leading industries to form distinctive industrial clusters of grain, tea, and Chinese medicinal herbs, promoting the stepped, gradient, and differentiated development of the industrial parks and establishing a “1+N” multi-chain integrated industrial pattern. However, the development of industrial parks still needs improvement in terms of structural balance across levels, value-added along the industrial chain, and regional brand synergy. To address these issues, the following strategies are proposed. First, optimize the gradient construction of the parks by formulating a four-tier linked mechanism, implementing “one park, one policy” measures, and sharing resource factors, so as to strengthen reserve forces and increase the proportion of national-level parks. Second, promote full-chain industrial integration by relying on universities and research institutes to tackle technological bottlenecks, building a municipal agricultural big data center, and combining prepared food processing, cold-chain logistics, and new cultural tourism scenarios to expand value-added spaces. Third, build a brand matrix by establishing a three-tier framework of “municipal leadership – county-level feature support – park-level innovation”, and leveraging industry associations and enterprise collaboration to shift brand promotion from fragmented corporate efforts to clustered synergy, thereby enhancing overall market reach and core competitiveness.
This article analyzed the current situation of agricultural industrialization development in Caoxian, Shandong Province, identified the aspects that need improvement, and proposed development strategies. Based on local resource endowment and geographical conditions, the research area focuses on the cultivation of leading industries and characteristic agricultural products, and vigorously promotes the development of high-value processing of agricultural and sideline products. A preliminary industrial structure has been established, featuring wood processing, food processing, and cotton and wool textile as the main industries.

This can promote the improvement and enhancement of regional agricultural industrialization, as well as its transformation and upgrading. This article provides a reference for improving the development level of agricultural industrialization.
To accurately grasp the production factor resources in tobacco-planting areas, optimize the spatial layout of the tobacco industry, and achieve cost reduction, quality improvement, and efficiency enhancement in tobacco production, a practical study on constructing a digital tobacco village based on UAV aerial surveying was carried out. A quad-rotor UAV equipped with a P1 visible-light camera was employed for regional aerial surveying and image acquisition. Combined with field investigations, multi-source data including farmland distribution, facility layouts, labor resources, and agricultural machinery services were integrated to construct a digital tobacco village one-map platform. The application effects of the platform were validated through field controlled comparative experiments conducted from 2023 to 2024 and through grading inspections of purchased tobacco leaves. The results showed that UAV aerial surveying significantly improved the measurement accuracy of tobacco field areas. After implementing standardized fertilization and other agronomic operations based on the precise area data, the average yield per unit area in the experimental fields increased by 15.77 kg/hm². The quality of purchased tobacco leaves was also markedly improved, with the qualification rates of middle-grade C4F and lower-grade X2F tobacco increasing by 8.45 and 3.18 percentage points, respectively. Issues such as mixing of green and off-type leaves, mixing of grades, and mixing of stalk positions were effectively alleviated. In summary, the digital tobacco village provides robust data support for tobacco enterprises in production planning, resource allocation, and field technical guidance, effectively optimizing the tobacco grade structure. Future efforts should continue to improve the construction of the digital tobacco village and expand digital application scenarios such as disaster monitoring in tobacco fields, production trusteeship, and precision agricultural machinery operations, so as to empower the high-quality development of the tobacco industry through digital technologies.
This paper systematically summarized the technical measures and outcomes of agricultural schistosomiasis control in Ma’anshan City, Anhui Province, analyzed challenges faced, and proposed corresponding recommendations for future development. By establishing a robust working mechanism, establishing a livestock schistosomiasis surveillance network, implementing comprehensive control strategies (e.g., agricultural restructuring, breeding transformation, agricultural mechanization promotion, environmental remediation, rural renovation, and fishermen relocation), and enhancing workforce capacity building, the study area has met the criteria for schistosomiasis elimination. However, its practical work still faces certain challenges in agricultural restructuring, long-term management of comprehensive control projects, and capacity building at the grassroots level. In response, the following countermeasures are proposed: upgrading epidemic prevention facilities for livestock, strengthening grazing oversight and emergency response; clarifying management responsibilities, refining assessment frameworks, establishing sustainable funding mechanisms, and fostering public engagement in collaborative governance; and optimizing personnel allocation, developing routine training programs, and enhancing the professional competence of grassroots teams on a continuing basis. This paper provides a reference for agricultural schistosomiasis control in similar regions.
Taking the Yu’an District State-owned Forest Seed Farm as the research object, this paper analyzed the current status of forest tourism development and key links requiring attention, and proposed corresponding optimization paths. The seed farm has established an operation system featuring industry-university-research collaboration and ecological resource protection; it has initially formed product formats including ecological popular science and outdoor recreation; infrastructure such as roads, water and power supply systems and intelligent management facilities has been continuously improved; and the popularity of outdoor tourism of the farm has been enhanced by hosting outdoor events. A basic framework for forest tourism development has been established overall, yet there remains considerable room for improvement in institutional mechanism construction, in-depth product development, supporting service facilities, marketing systems and brand influence. On this basis, the following optimization paths are put forward: constructing a multi-stakeholder collaborative operation model and building an information sharing platform covering cultural tourism, environmental protection and transportation; carrying out targeted design according to forest characteristics to create featured scenarios such as popular science education zones, landscape avenues and picking and processing experience areas; optimizing tour route planning and installing multilingual guide signs and maps at major scenic spots and intersections; conducting targeted promotion via online publicity and new media platforms, and developing under-forest planting and breeding industries by utilizing abundant under-forest resources within the farm. This study provides references for the sustainable development of forest tourism in forest farms.
This paper systematically reviewed the current status and constraining factors of fertilizer reduction and efficiency enhancement in Shandong Province, and proposed development suggestions. In recent years, the amount of chemical fertilizer used in the study area has continued to decline, and the promotion of new-type fertilizers and organic fertilizer substitution has achieved notable results. However, certain challenges remain in areas such as awareness of nutrient structure optimization, market mechanisms for promoting new-type fertilizers, service systems for organic fertilizer substitution and promotion, as well as intelligent fertilization facilities and digital platforms. Accordingly, the following optimization strategies are proposed: establish a three-tier transmission mechanism of “production–supply–application” for formula fertilizers at the county level, while strengthening the support of grassroots technical personnel; improve the “trial–demonstration–popularization” system for new-type fertilizers, and promote the integration of seed and fertilizer application along with quality and cost control; cultivate socialized service entities, advance county-wide manure returning to fields, and implement differentiated measures by region; promote intelligent fertilization equipment in a categorized manner, combining government guidance with service purchasing, and build a dynamic closed-loop management system for soil nutrients based on data platforms to enhance precision fertilization. This article provides a reference for the relevant regions to carry out the work of reducing fertilizer application while enhancing its efficiency.
Based on the forestry statistics of Fujian Province, this paper used the grey relational analysis method to construct a grey dynamic correlation matrix and analyse the correlation degree between the total forestry output value and the output values of the three forestry industries in this region from 2017 to 2022. The results showed that from 2017 to 2019, the average correlation degree of the three forestry industries and the total output value in this area was ranked as the secondary industry > the primary industry > the tertiary industry; from 2020 to 2022, the ranking changed to the secondary industry > the tertiary industry > the primary industry. The correlation degree between the forestry secondary industry and the total output value in this area was the highest, always occupying a dominant position. The average correlation degree of the forestry three industries and the total output value changed from the pattern of “second, first, third” to “second, third, first”. The forestry industry in this region generally presents a pattern where the secondary industry leads and supports, the tertiary industry grows rapidly, and the primary industry develops steadily. Based on the concept of adapting to local conditions and pursuing characteristic development, relying on the forestry resources and industrial foundation advantages of Fujian Province, a development path has been proposed to consolidate the first-level forestry industry with high precision, cultivate the second-level innovative forestry industry, and expand the third-level large-scale forestry industry. This can promote the deep integration of the three industries and help Fujian’s forestry industry achieve high-quality development.
