[0016] Beneficial effects:

[0017] 1. The present application is aimed at a large number of pathogenic bacteria in the soil, and the rotary tiller works while the soil is turned over, the dielectric barrier discharge device intermittently ionizes air to generate various forms of active substances and high-energy electrons, the active substances contact the surface of soil microorganisms to cause oxidative damage to cells, and ultimately lead to the death of bacterial cells, the high-energy electrons increase the soil temperature, thereby killing harmful organisms in the soil and interfering with the accumulation and reproduction of harmful microorganisms, so as to achieve the purpose of preventing and treating soil pests and diseases.

[0018] 2.The present application is aimed at the field with stable yield and large amount of residual pesticides, soil structure change and influence on crop root growth environment, the mechanism with soil repair function of the present application will effectively solve this condition. The dielectric barrier discharge device is covered with an insulating medium layer (ceramic sheet) on the high-voltage electrode sheet. When a high-voltage alternating electric field is applied between the high-voltage electrode plate and the grounded electrode plate, due to the presence of the medium layer, the processing object occurs uniform and diffuse filamentous streamer discharge. In this discharge process, the electron energy is higher than the average electron energy value of corona discharge and spark discharge, which can fully ionize organic molecules, water molecules and oxygen molecules, thereby exciting higher active particles and large volume, high concentration of low temperature plasma, which can effectively degrade the residual pesticides in the soil.

The high-low dual shaft mechanism is adopted, the soil can be more efficiently crushed, the growth environment of crops can be optimized in depth, and the root system can normally absorb nutrients in the soil, thereby improving the yield of crops on the basis of reducing the amount of fertilization. In order to further improve the soil crushing efficiency of the rotary cultivator, the electrode sheet shape of the dielectric barrier discharge device in the present application is similar to a wedge shape, the high-voltage electrode sheet is made of aluminum plate, the dielectric layer uses ceramic sheet, covers the high-voltage electrode sheet in the middle, and the grounded electrode is made of steel plate. The rotary cultivator blade shaft drives the rotary blade to rotate, the soil is quickly loosened, and the turned soil is crushed again when it collides with the electrode sheet, thereby improving the work efficiency.

[0020] 4.During rotary cultivation, the battery pack supplies power to each power component, the high-voltage module provides high voltage for the dielectric barrier discharge device, and the rotary cultivator blade shaft drives the rotary blade to rotate. The soil is turned, and the dielectric barrier discharge device intermittently ionizes air to produce various forms of active substances and active particles with electron energy higher than the average electron energy of corona discharge and spark discharge, which contacts the surface of soil microorganisms, causes oxidative damage to cells, and finally leads to the death of bacterial cells in the soil. In addition, the dielectric barrier discharge device generates large volume, high concentration of low temperature plasma, which can effectively degrade the residual pesticides in the soil. The rotary cultivation mechanism with soil repair function of the present application not only has high sterilization efficiency, but also can degrade residual pesticides, repair soil structure and save energy, which is more in line with the concept of environmental friendly.
