机械深松技术是指用不同的动力机械配套相应的深松机械,来完成农田深松作业的机械化技术。机械深松的目的是疏松土壤,打破犁底层,增强雨水入渗速度和数量,减少径流,减少水分蒸发损失。由于机械深松是只松土、不翻土,作业后使耕层土壤不乱,动土量小,所以特别适合于黑土层浅、不宜耕翻作业的土壤。机械化深松按作业性质可分为局部深松和全面深松 Mechanical deep loose technology refers to the use of different power machinery supporting the corresponding deep loose machinery, to complete mechanized farmland deep pine operations. The purpose of mechanical subsoiling is to loosen the soil, break the plow bottom, enhance the infiltration rate and quantity of rainwater, reduce runoff and reduce the loss of moisture evaporation. As mechanical loose is only loose soil, not soil, after farming so that soil is not chaos soil, a small amount of soil, it is particularly suitable for the black soil shallow, should not be tilled soil. Mechanized deep pine by job nature can be divided into local deep loose and comprehensive deep pine
