Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of corn conservation tillage mechanization, and relates to a device for rotary tillage of seedling belts except for straw covering areas before planting. BACKGROUND

[0002] In recent years, the area of corn planted by using the conservation tillage technology in China has been continuously increasing, and the straw returning technology has also been continuously popularized and applied in a large area. However, the straw returning technology has certain adverse conditions. The straw returning technology is carried out under the premise of no soil movement. Although the straw returning technology plays a certain protective role on the soil, the soil is seriously compacted due to the movement of the machine into the soil for many years, which is not conducive to the rapid entry of water into the soil, the soil is not loose enough, and the ground temperature rises slowly compared with the traditional ridge tillage. Some farmers hope to use the straw returning technology of the conservation tillage and also hope to retain the advantages of the traditional ridge tillage. However, under the condition of straw full-returning, the traditional soil preparation machine cannot complete the operation requirement. In view of the above-mentioned situation, the seedling belt tillage and integration operation machine provided by the present application can solve the above-mentioned problems. The present application ensures that the rotary tillage of the seedling belt can be effectively carried out under the condition of straw full-returning, the surface compacted soil is improved, the ground temperature is increased, the water retention capacity of the soil is increased, and a high emergence rate is maintained, so that stable yield and high yield are ensured, and the purpose of breaking the surface compacted soil, retaining water and increasing the ground temperature is achieved under the straw full-returning mode. The appearance of the present application will greatly promote the rapid development of the conservation tillage. SUMMARY

[0003] The present application aims to provide a machine for shallow rotary and pressing of the soil of the seeding belt after straw returning.
