改进直播水稻的氮肥管理,对提高直播水稻栽培效益有十分重要意义。本文分析了直播水稻氮肥利用率低的原因,探讨了有效提高单季直播水稻氮肥利用效率的有关农艺措施。
Improving the nitrogen management of direct seeding rice is very important to improve the cultivation efficiency of direct seeding rice. In this paper, we analyzed the reasons for the low nitrogen use efficiency of direct seeding rice and discussed the agronomic measures that could effectively increase the nitrogen use efficiency of direct seeding rice.
