| 摘 要： | 通过田间定位试验,研究不同耕作方式对华北小麦、玉米一年两熟农作区夏玉米开花后叶片衰老生理特性及产量的影响。结果表明,秸秆还田和隔年深耕可以显著提高玉米叶片各生育期SOD、POD活性,且MDA含量一直保持在较低水平,维持了叶片后期较高的生理功能,最终产量表现为秸秆还田与隔年深耕相结合时产量高于其他处理,起到良好的增产效果。

| Abstract: | Based on the method of fixed field location experiment,this article studied the effect of the alternate years deep plowing on ear-leaf senescence and yield in the areas of wheat-corn two crops a year of North China Plain.The results have shown that the alternate years deep plowing led to increase SOD and POD activity and keep the content of MDA in a low level in summer maize,all these made leaf physiological function stronger in later growing period.Finally,straw application with alternate years deep plowing got the best result,and the yield was higher than the other treats. |
