摘要
机械深松整地技术,可打破犁底层,加深耕作层,形成虚实并存的耕层构造,为农作物发育创造良好的土壤条件。为此,介绍了机械深松整地的技术体系,并以青冈县为例进行了经济效益分析。
The technology of machinery subsoiling and land-preparation is used for breaking the plow pan, deepening the cultivated layer, and forming the coexistence of imaginariness and real cultivated layer structure. This technology creates the suitable soil conditions for the crop development. Hence, this paper introduces the technical system of machinery subsoiling and land-preparation, and analyzes the economical benefits of this technology using in Qinggang County.
