摘要
提出了一套简单易行的麦稻秸秆全量整草免耕还田方法。连续两年的试验结果表明:晚稻草覆盖大麦田还田,对大麦的增产效果极显著,全量还田处理的增产效果显著大于半量还田,而麦秆田沟埋草还田对晚稻产量的影响较小;麦稻秸秆还田培肥土壤效果显著,连续两年还田后,土壤速效P、速效K含量大幅度提高,有机质、全N、碱解N含量也有较大幅度的提高。
A Series of feasible means of all wheat and rice straw application without chopping and cultivation were put forward.The results of two years straw application test showed that the yield of wheat in the treatment in that rice straw were returned to surface of wheat field were most significant higher than that in the contrast. The yield of all straw application treatment was significant higher than that of a half straw application.The effect of returning wheat straw to the ditch in rice field on rice yield was not significant.The effect of straw application on soil fertility was noticeable.After straw application for two years,the contents of rapidly available P and rapidly available K were increased high extent, and contents of organic matter and nitrogen were also increased.
