Abstract

Abstract:

In order to implement the action plan for large-scale increases in grain yield per unit area, field experiments and demonstrations of rice reasonable close planting cultivation techniques for yield increase and efficiency enhancement were conducted in Wengyuan County, Shaoguan City, Guangdong Province, during the late season of 2024 and the early season of 2025. The trial included two treatment groups: “farmers’ conventional cultivation technique” (hereinafter referred to as “farmers’habits”) and “rice reasonable close planting cultivation technique for yield increase and efficiency enhancement” (hereinafter referred to as ‘reasonable close planting’). The effects of the two cultivation techniques on rice yield and its components, total biomass, harvest index, nitrogen use efficiency, and economic benefits were systematically analyzed. The results showed that, compared with “farmers’ habits” cultivation technique, the ‘reasonable close planting’ technique significantly increased the number of effective panicles (by 12.86%-29.87%), biomass (by 13.38%-29397%), and grain yield (by 22.11%-27.51%), while also enhancing nitrogen partial factor productivity (by 46.64%-62.60%) and net income (by 106.46%-109.66%). These findings confirm that the ‘reasonable close planting’ cultivation technique could provide a scientific basis and technical support for large-scale increases in rice yield per unit area and economic benefit.

Key words: rice, reasonable close planting, grain yield, nitrogen use efficiency, economic benefit

摘要：

为落实粮食大面积单产提升行动，于2024年晚季及2025年早季在广东省韶关市翁源县开展了水稻合理密植增产增效栽培技术的试验示范。试验设置了“农民习惯栽培技术”（以下简称“农民习惯”）和“水稻合理密植增产增效栽培技术”（以下简称“合理密植”）两个处理组，系统分析了这两种栽培技术对水稻产量及其构成因子、总生物量、收获指数、氮肥利用效率及经济效益的影响。结果表明，与农民习惯栽培技术相比，合理密植技术显著提高了水稻有效穗数（增幅12.86%~29.87%）、生物量（增幅13.38%~29.97%）和稻谷产量（增幅22.11%~27.51%），同时提升了氮肥偏生产力（增幅46.64%~62.60%）和纯收入（增幅106.46%~109.66%）。上述结果表明，合理密植栽培技术可为水稻大面积提产增效提供科学依据与技术支撑。
