大豆高垄平台土壤生态环境动态变化

Dynamic changing of soil ecology environment under soybean high flat ridge culture condition

通过对大豆高垄平台耕法和垄作土壤环境的研究表明 ,高垄平台耕法不仅是解决低湿易涝问题而且是增产的一项重要技术措施。高垄平台耕法改变了土壤生态环境 ,降低土壤含水量及土壤容重 ,提高土壤温度。采用高垄平台耕法种值的大豆保苗株数增多 ,根瘤数增加 ,且比垄作增产。

The research of the soil biological environment of high flat ridge culture indicated that high flat ridge culture was not only a better solution to the problem of low wet and easily waterlogged areas,but also an important cultivation measure for raising crop yields.High flat ridge culture changed the soil biological environment,lowered water content of the soil and unit weight of the soil and raised the temperature of the soil.The survived plants and nodule numbers of high0flat ridge culture wer more than those of ridge culture,as the yields.$$$$
