本文分析了江苏南通如东地区水稻种植的基础条件,系统总结了当地水稻种植的关键技术。该地区光热资源丰富,具备水稻增产潜力,但台风、高温与土壤盐渍化等因素对水稻生产造成了一定影响。基于此,整合品种选育、水肥精准管理与绿色防控等措施,构建了适配区域生态条件的水稻种植技术体系。具体包括筛选耐盐基因型稳定的抗逆性品种,如南粳5055等;采用旱育秧技术,构建物理结构与化学环境协同调控的旱育苗床,于秧苗第2.5叶展开时和移栽前5 d进行胁迫适应训练,培育抗逆壮秧;构建缓混肥养分时空精准控释体系(氮素释放高峰期对接分蘖盛期,磷素活性维持至幼穗分化期),氮、磷、钾肥施用量分别为165、75、105 kg/hm2;确立“排盐压碱—生理需水”双轨水分调控机制,实施“浅水促蘖—寸水护胎—干湿防衰”的水分精准调控;构建绿色防控体系,通过物理(布设声光组合诱捕器等)与生物(喷施200亿孢子/g枯草芽孢杆菌可湿性粉剂等)防控的协同作用,维持稻田生态系统益害比为1∶2。本文为滨海盐碱区水稻绿色、稳产、高产提供参考。

This paper analyzed the basic conditions for rice cultivation in the Rudong area of Nantong City, Jiangsu Province, and systematically summarized the key technologies for local rice cultivation. The region is rich in light and heat resources and has the potential for increasing rice production, but typhoons, high temperatures and soil salinization have certain impacts on rice production. Based on this, the paper integrated core technologies such as variety breeding, precise water and fertilizer management, and green prevention and control, and established rice planting technologies suitable for regional ecological conditions. Specifically, it includes screening salt-tolerant genotypes with stable resistance varieties, such as Nanjing 5055, etc.; adopting dry seedling raising technology, constructing a dry seedling bed with coordinated regulation of physical structure and chemical environment, and conducting stress adaptation training when the second and a half leaf of the seedling unfolds and 5 days before transplanting to cultivate resistant and vigorous seedlings; constructing a precise controlled-release system of compound fertilizer nutrients in time and space (the peak period of nitrogen release is in line with the tillering peak period, and the phosphorus activity is maintained until the young panicle differentiation period), with the application rates of nitrogen, phosphorus and potassium fertilizers being 165, 75 and 105 kg/hm2 respectively; establishing a dual-track water regulation mechanism of “salt drainage and alkali suppression-physiological water demand”, and implementing precise water regulation of “shallow water promoting tillering-inch water protecting the embryo-dry and wet preventing senescence”; constructing a green control system, through the coordinated effect of physical (setting up sound and light combination traps, etc.) and biological (spraying 200 billion spores/g Bacillus subtilis wettable powder, etc.) control, maintaining the ratio of beneficial to harmful organisms in the paddy field ecosystem at 1∶2. This paper provides a reference for green, stable and high yield rice production in coastal saline-alkali areas
