摘要
研究表明：麦秸全量覆盖玉米行间有明显的抑草作用,抑草率达89.8%~91.6%,干旱年份提高土壤含水量2.26%,培肥地力,提高玉米产量13.3~23.1%。
The study indicated that covering of wheat straw between the cornfield rows has an obvious effect of weed suppressing,which can be up to 89.8% to 91.6% ,and it can raise the soil moisture in arid year by 2.26% ,and it also can increase the soil fertility and promote the corn yield by 13.3% to 23.1%.
