摘要
研究表明,小麦秸秆覆盖对杂草数量和夏玉米产量有明显影响。与传统处理相比,常量小麦秸秆覆盖可减少25.5%的杂草数量,而加倍的覆盖可以减少杂草数量62.4%。小麦秸秆常量覆盖和加倍覆盖可使夏玉米分别增产10.7%和3.4%。
Tne wheat stalk-covering on field is a practice technology for controlling weeds and average 25.5% of weed plant in number was reduced compared with wheat residue-removing. Tne effect of double-lay of the wheat stalk-covering on weed was more significant. Tne result showed that the wheat stalk-covering had significant effect on yield of summer corn and in the normal wheat stalk-covering the corn yield reached to the highest （9 563.4 kg/hm^2） .The yield was bv increased to 10.7% with the normal wheat stalk-coverlng and 3.4%, with double-lay of the wheat stalk covering.
