不同程度压实对土壤理化性状及作物生育产量的影响

    Effects of Different Level Compaction on the Physicochemical Characteristerics of Soil and Crop Growth

    • 摘要: 采用大、小四轮式拖拉机在冬小麦播种地上压地1到10遍,对照为未压实地,测定对小麦生育产量影响;同时进行了不同程度土壤压实后孔隙度为58%,52%,46%和40%的土壤理化性状测定试验。结果表明不同程度压实具有系统累积效应,为免耕、保护性耕作和减免中耕提供了运用依据。

       

      Abstract: The physicochemical characteristics of soil and crop growth are measured after 1 to 10 times compacted with large and small wheeled tractor operated on the sowing land. CK is uncompacted land; Meanwhile experiments after different compaction at porosity of 58%, 52%, 46% and 40% were carried out to determine soil physicochemical parameters. The research shows that the different level compaction got systematic accumulated effects of it. And it provides basis for application of no-tillage, conservation tillage and reduced inter-cultivation.
