Abstract:In this paper, the feasibility of different straw mulching methods in the western spring maize area of the northeast plain was systematically evaluated through field positioning test. Compared with conventional tillage, the effects of straw mulching and straw mulching methods on maize yield, soil physical and chemical properties and economic benefits were investigated. The results showed that: compared with the conventional grown,the two methods of straw returning had better yield-increasing effect,with the increase of 9.84% in straw mulching and 8.01% in straw rotary mixing; the way of straw mulching could effectively improve soil fertility,with the increase of hydrolytic nitrogen,available phosphorus,available potassium,total nitrogen and total phosphorus of 4.97%,67.17%,12.33%,6.28% and 14.74%,respectively. Total potassium increased by 0.98%,pH decreased by 1.83%,organic matter increased by 7.55%. Compared with conventional planting methods,the two straw returning methods had better economic benefits with 21.21% increase in revenue of straw mulching cultivation method and 10.60% increase in revenue of straw rotary mixing cultivation method,which could be properly promoted in this area.
