Description

[0002] Deep tillage can comprehensively improve the quality of cultivated land, enhance the soil's ability to store water and retain soil moisture, resist drought and drain waterlogging, improve agricultural comprehensive production capacity, and promote sustainable agricultural development. However, at present, ordinary deep tillage has problems such as high power consumption and large traction resistance; self-excited vibration deep tillage has disadvantages such as poor stability and insignificant drag reduction effect; mechanical forced vibration deep tillage requires the tractor power output shaft to drive the vibration components, although it can reduce traction resistance, the total power consumption has not been reduced, and there are disadvantages such as saving labor but not work, and complex transmission; at the same time, there is little research on combined land preparation machines with fertilization devices in China. Usually, manual fertilization or mechanical fertilization is carried out separately. Manual fertilization has disadvantages such as high labor intensity and low efficiency; mechanical fertilization is followed by land preparation, which causes the machine to enter the ground many times, resulting in soil compaction and reduced soil permeability.
