摘　　要：采用施肥季节调控、秸秆覆盖、地腊覆盖、缓效肥料等普通农艺措拖,对影响土壤中铵态氮固定的环境条件进行调节,可以实现对铵态氮固定与释放过程的人为干涉,有利于提高氮肥肥效、减少氮素损失。The ammonium fixation and release were adjusted by changing their factors through fertilizer application management, srtaw mulching, plastic film mulching and slow-releasing fertilizer application. Through this regulation. Nitrogen fertilizer use efficiency was improved and nitrogen loss was reducde.
