| 摘 要： | 通过大田试验研究了8种不同保护性耕作对玉米生长发育及产量的影响。试验结果表明，从生长发育看，垄膜集水处理的玉米在株高、叶面积系数等方面的生长更协调；在玉米的生育前期，平铺膜处理促进玉米的生长发育，玉米株高、叶面积系数、干物质量明显高于对照，而到后期，各个生育指标逐渐下降，表现出早衰；免耕和秸秆覆盖处理在前期生长发育缓慢，株高、叶面积系数和干物质量均不同程度低于对照，到中后期，生长发育加快。从产量形成看，保护性耕作措施出苗率均低于对照，从而影响产量的形成。8种保护性耕作措施中，垄膜集水措施和传统耕作＋秸秆覆盖处理表现增产，平均产量分别比对照提高16％和11％。

| Abstract: | The field experiment was conducted to study the effects of eight kinds of conservation tillage on development and yield of maize.The results showed that:from the growth and development,long membrane set treatment of corn plant height,leaf area index and so the growth of a more coordinated;maize growing in the early stage of dealing with the promotion of corn-ping filming growth and development,maize plant height,leaf area index,dry matter was significantly higher than the control volume,and by the late decl... |
