江苏丘陵地区实现杂交水稻大面积单产提升的技术路径探索及成效分析
Exploration of Technical Pathways for Large-Scale Unit Yield Improvement of Hybrid Rice in the Hilly Areas of Jiangsu and Analysis of Achievements
摘要
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.关键词
