Abstract

Abstract:

To address the critical constraints limiting hybrid rice productivity in the hilly regions of Jiangsu, including fragmented farmland, infertile soils, frequent extreme weather disasters, extensive field water and fertilizer management, and a lack of stress-resistance techniques, this study established a high-yielding and efficient cultivation system centered on the “Three Preventatives and Four Controls” strategy. Using Luhe District in Nanjing as a representative study area, the core technical components include: “Three Preventatives” (lodging prevention, heat stress mitigation, and pre-harvest sprouting control) and “Four Controls” (management of sowing/transplanting quality, water regimes, fertilizer application, and weed control). Multi-site demonstration results from 2024 to 2025 indicated that, compared to conventional local practices, this integrated technology increased the regional unit yield by 8%-15%, reduced herbicide application frequency by one instance, and significantly enhanced fertilizer use efficiency. Farmers’ net income increased by 205 CNY per 667 m². Notably, the demonstration site in Zhuzhen Town secured first place in the Jiangsu Provincial Rice High-Yield Competition for two consecutive years. This technical system is well-adapted to the soil and climatic characteristics of Jiangsu’s hilly areas, effectively breaking the bottleneck of stable yield increases. It provides a replicable and scalable solution for stabilizing grain production capacity and achieving cost-efficiency in agriculture.

Key words: hybrid rice, hilly region, unit yield improvement, three preventatives and four controls, cultivation technique, cost reduction and efficiency enhancement

摘要：

针对江苏丘陵地区田块零散、土壤瘠薄、极端气象灾害多发、田间水肥管理粗放、抗逆减灾技术缺失等制约杂交水稻产能提升的突出问题，以南京市六合区为典型研究区域，构建以“三防（防倒伏、防高温热害、防穗发芽）、四控（控播栽质量、控田间水分、控肥料运筹、控田间杂草）”为核心的杂交水稻高产高效栽培技术体系。2024—2025年多点示范结果表明，相较于当地常规栽培模式，该集成技术可实现区域水稻大面积单产提升8.0%~15.0%，减少除草剂施用频次1次，肥料利用效率显著提升，农户每667 m²净收益增加205元；其中竹镇镇示范片区连续两年在江苏省水稻高产竞赛中获第一名。该技术体系适配江苏丘陵地区土壤与气候生产特征，可有效破解区域水稻稳产增产瓶颈，为江苏丘陵地区粮食产能稳固、农业节本增效提供可复制、可推广的技术方案与实践参考。
