一种冬闲杂草免耕还田配施氮肥的水稻增产方法
By crushing weeds and spraying a dual-response slow-release nitrogen fertilizer consisting of directional inducing microbial agents and coated urea granules, a synergistic reaction matrix is constructed, which solves the problems of slow weed decomposition and low nitrogen fertilizer utilization, and realizes dynamic nitrogen release and increased rice yield.

Abstract
本申请涉及农业技术领域，公开了一种冬闲杂草免耕还田配施氮肥的水稻增产方法，包括以下步骤：粉碎平铺冬闲杂草，喷施含信号分泌菌群的菌剂；用含信号响应微生物的包衣液，包覆尿素制缓释氮肥；将缓释氮肥施于杂草层，经浅层作业混合形成反应基质；调控基质水分，以传导信号分子，激活微生物启动释放；将水稻移栽于基质中，利用其养分进行全生长期栽培。本发明通过构建一体化的协同反应基质，使杂草分解体系与肥料响应体系在物理空间上紧密耦合并在功能上相互促进，杂草分解过程不仅为肥料释放提供了生物信号，其分解产物可作为缓释壳内微生物的碳源，微生物的代谢产物可反向促进杂草的分解，提升了杂草还田的资源化效率与系统的整体效能。
