The traditional rotary tillage land preparation mode needs a plurality of operations to bury the straws on the ground well, and meanwhile, the common rotary tillage cutter has a poor crushing effect on the corn stubbles, and the land preparation operation is complicated, time-consuming and labor-consuming. The rotary cultivator is used for cultivating farmland soil, so that the production efficiency is low, the cultivating depth is limited by machinery, the operation depth is about 15 cm generally, and soil hardening is easily caused in the lower part. At present, the two-harvest in one year in North China is cultivated by a rotary cultivator, and the operation requirement before sowing can be met only by carrying out rotary cultivation twice. The defects of a tractor that the times of grinding soil are more, the power consumption is large, the operation times are more and the like exist. Because the surface of the land before plowing in the area of two crops in one year in North China is covered with a large amount of corn straws and unprocessed stubbles, a large amount of straws are mixed with soil after plowing by a rotary cultivator, and the straws are not well covered by the soil, so that the seedling quality and the yield of wheat are influenced.

A share plow for a tractor is an agricultural implement for tilling land, and is a fully suspended share plow consisting of a heavy blade at the end of a beam, usually attached to a set of tractors that tow it, for breaking up clumps of soil and plowing out furrows in preparation for sowing. The deep ploughing machine can deeply plough and deeply turn 15-35 cm of a field, and has the effects of breaking a plough bottom layer, recovering a soil plough layer structure, improving the water storage and soil moisture preservation capability of soil, covering straws, eliminating part of weeds, reducing plant diseases and insect pests, leveling the ground surface and the like. However, the function of the furrow plough for the tractor is single, only deeply ploughs and deeply ploughs the field, and does not have the function of leveling the field, and the stubble of the corn or other crops is thicker due to the existence of weeds in the field, so that the resistance of the furrow plough to wind the vines is increased easily during working, and the stubble is not crushed to cover the field, thereby influencing the seedling quality and yield of the wheat of the next crop.
