2.
To investigate the effects of rice straw incorporation and nitrogen application models on nitrogen supplying capacity of soils,nitrogen using efficiency and rice productivity in the double rice cropping systems,field experiments were conducted on a farmer s field in Taojiang County in April of 2003,using split-plot design with two main treatments,three subplot treatments and eight replications.
结果表明,稻草还田改善了土壤的供氮能力,不论在背景氮较低的砂性土壤上还是在背景氮较高的粘性土壤上,稻草还田配施减量氮肥(N1、N3处理全年施氮量180kg。
