The deep-sink mechanization technology is a soil cultivation technique that only loosens the soil without inverting the soil layer. Breaking the bottom of the plough and increasing the infiltration speed and quantity of the rainwater have little disturbance to the soil, and most of the debris remains on the surface, which is conducive to protecting the wind and preventing wind erosion. Deep-sinking mechanization technology usually employs tractor suspension deep loosening machines for operations. Deep loose form and technical requirements: deep loose, including full deep loose and partial deep loose two. Comprehensive deepening is the use of inverted V all-round deep loosening machine according to different crops, different soil conditions for the corresponding deep loose operation. The main technical requirements are: (1) Suitable tillage conditions. Soil moisture content is 15%-22%; (2) Operation requirements. Deep depth of 35-50 centimeters; deep loose time: after the straw processing before sowing; loose and deep consistency in the operation, and may not be repeated or loose phenomenon; (3) supporting measures. When the weather is too dry, ostrich formation can be carried out; (4) Operating cycle, according to the soil conditions and the density of equipment into the ground, generally loose once every 2 to 3 years.
