| 摘 要： | 通过对免耕覆盖对玉米生长发育及产量影响的研究,结果表明：免耕覆盖和传统耕作条件下的玉米株高和地上干物质只有在苗期表现差异显著,其他时期差异不显著;免耕覆盖较传统耕作玉米叶面积指数下降得慢,维持较高水平的时间相对较长;免耕覆盖的玉米比传统耕作条件下的产量表现为增产。因此免耕覆盖栽培措施具有可行性,值得推广。

| Abstract: | The effect of no-tillage and cover on maize growth and development and yield was conducted, the results showed that under the condition of no-tillage and convention tillage,the difference of plant height and dry matter weight were significant only in seedling stage. The leaf area index of under the condition of no-tillage decreased slowlier and maintain on high level longer than thoes of convention tillage. The yield with no-tillage was higher. Therefore, the cultivation of no-tillage and cover was feasible, it was valuable for extension. |
