摘    要:在黄土区春玉米地实施免耕和传统耕作的基础上,研究了秸秆覆盖、地膜覆盖、秸秆地膜双覆盖以及不覆盖下春玉米产量和土壤肥力的变化.结果表明:传统耕作下不覆盖的产量为6 212.75 kg/hm2,秸秆覆盖比不覆盖增产45.67%,地膜覆盖增产47.24%,秸秆地膜双覆盖增产幅度可达73.24%;免耕下秸秆覆盖比不覆盖仅增产了...

Abstract:This research is based on the implement of tillage and no-tillage farming with straw mulching,plastic film mulching,straw and plastic film mulching or without mulching to study the changes of spring maize yield and soil fertility.The result shows: On the basis of tillage without mulching spring maize yield is 6 212.75 kg/hm2,straw mulching increases yield by 45.67% compared with no mulching,plastic film mulching increases yield by 47.24%,straw and plastic film mulching increases yield by 73.24%;On the basis...
Keywords:conservation tillage  spring maize  water use efficiency  soil fertility
