水稻氮肥减量条件下不同氮肥运筹比例产量效果与集成技术应用

Yield Effect and Integrated Technology Application of Different Nitrogen Fertilizer Operation Ratios under the Condition of Reducing Rice Nitrogen Fertilizer

摘要: 在水稻大面积生产高产田氮肥用量基础上减少10%氮肥用量条件下，研究最佳氮肥运筹比例，实现减肥不减产目标。研究表明：最佳氮肥运筹比例为基蘖肥:穗肥 = 5:5，笔者同时提出关键配套技术措施。

Abstract: Under the condition of reducing the amount of nitrogen fertilizer by 10% on the basis of the amount of nitrogen fertilizer used in large-scale rice production and high-yield fields, research the optimal nitrogen fertilizer operation ratio to achieve the goal of losing weight without reducing production. The research shows that the optimal nitrogen fertilizer operation ratio is base tiller fertilizer:ear fertilizer = 5:5, and the author also proposes key supporting technical measures.
