阴阳土分种深耕法是深翻土地改良土壤的方法之一,它与一般深翻法不同点,在于通过深翻把阴土(生土)与阳土(熟土)分别集中成为一条阴土、一条阳土,为玉米和大豆进行大间作准备条件。这种耕作法简便易行,即从地的一边掘开二尺宽一尺半深的沟,将土翻在一边,紧挨着沟掘一条四尺宽的阳土填平沟,再把阴土翻动拆排成二尺宽,这样反复操作即成了二尺阳土、二尺阴土,地基平整、层次分明的土地(如图)。
The method of deep-tillage with yin and yang soil is one of the methods of soil improvement by deep tipping over land. It differs from the general method of deep tipping over by concentrating the overcast soil (raw soil) and the cedar soil (mature soil) into a single overcast soil , A sunny earth, ready for maize and soybeans. This tillage method is simple and easy, that is, from the side of the ground to dig two feet wide and a half deep ditch, turn the soil aside, next to dig a four foot wide sun filled the trench, and then shade The soil was torn and disassembled into two feet in width so that repeated operations became land of two feet, two feet of earth, a smooth foundation and a clear layer of land (pictured).
