本文分析了安徽省芜湖市化肥减量增效工作现状、需重点关注的环节,并提出未来提升路径。研究区2023年农用化肥施用量较2014年减少16.20%,2018—2023年化肥施肥强度年均减少16.83 kg/hm2;氮、磷、钾配比已优化为1:0.3:0.5,同时促进大量元素与中微量元素配合施用;化肥利用率有了一定程度的提升,2023年达42%。然而,当前化肥减量增效工作在测土配方技术与数据应用、“三新”(新技术、新产品、新机具)集成应用推广度与适用性、常规施肥方式效率与新型技术应用和化肥施用定额制推行等方面有待进一步提升。未来,可通过合理开展新型肥料应用、有机无机肥配施等田间试验,建立肥料配方发布固定渠道;推广已经成熟的“三新”集成应用模式,筛选应用效果良好的样地;采取侧深施肥、种肥同播等方式,强化机艺融合、技物融合;选择代表性区域进行化肥施用定额制推广示范,加强对普通种植户的技术培训等措施进一步实现肥料配方的不断优化和肥料利用率的明显提升。本文为研究区化肥减量增效工作的进一步推广提供参考。

This study analyzed the current status of chemical fertilizer reduction and efficiency improvement work in Wuhu City, Anhui Province, as well as the key links requiring focused attention, and proposed future improvement paths. In the study area, the agricultural chemical fertilizer application rate in 2023 decreased by 16.20% compared with that in 2014, and the chemical fertilizer application intensity decreased by an average of 16.83 kg/hm2 per year from 2018 to 2023; the ratio of nitrogen (N), phosphorus (P), and potassium (K) has been optimized to 1:0.3:0.5, while promoting the combined application of macronutrients with medium and trace elements. The chemical fertilizer use efficiency has been improved to a certain extent, reaching 42% in 2023. However, the current chemical fertilizer reduction and efficiency improvement work still needs further improvement in aspects such as the application of soil testing and formula fertilization technology and data, the promotion degree and applicability of the integrated application of “Three News” (new technologies, new products, new machinery), the efficiency of conventional fertilization methods and the application of new technologies, and the implementation of the chemical fertilizer application quota system. In the future, the continuous optimization of fertilizer formulas and a significant improvement in fertilizer use efficiency can be further achieved through measures such as reasonably conducting field experiments on the application of new fertilizers and the combined application of organic and inorganic fertilizers to establish fixed channels for releasing fertilizer formulas; promoting mature integrated application models of “Three News” and selecting sample plots with good application effects; adopting methods such as side-deep fertilization and seed-fertilizer co-sowing to strengthen the integration of machinery and agronomy, and the integration of technology and materials; selecting representative regions to carry out demonstration and promotion of the chemical fertilizer application quota system, and strengthening technical training for ordinary growers. This study provides a reference for the further promotion of chemical fertilizer reduction and efficiency improvement work in the study area.
