摘    要:通过长期定位试验(1986-1997年),采用正交旋转回归设计,在黑土地区不同培肥方式条件下,对土壤氮素持续应进行研究,研究表明:培肥阶段除不施肥区外,土壤全氮量都有所增加。进入耗竭阶段后,土壤全氮又不同程度的下降,只是不同处理变化速度不同而已。不同培育肥方式的N变化,在培肥阶段的贡献和耗竭阶段的残效,均依次为农肥>化肥>秸秆。

关 键 词:农肥  化肥  秸秆  黑土  持续效应  土壤肥力  培肥方式  土壤氮素  氮素残效

Abstract:With the method of rotational regression design, a long-term fertilizing location test was carried out with farm manure, chemical fertilizer and straw on black soils from 1986 to 1997. Result proved that total-N had been increased except No-fertilizer during the fertilized stage. Total-N was declined with different speed during the exhausted stage. Farm manure, chemical fertilizer and straw had different sustainable effects. The farm manure was superior to others in sustainable effect and it could totally improve the physical, chemical and biological characteristics of soil because of its full nutrients and low degradation rate.
Keywords:farm manure  chemical fertilizer  straw  black soil  sustainable effect
