Description

Technical Field

[0002] The rotary tillage film mulching and soil-returning technology is an efficient and environment-friendly modern agricultural tillage technology, which can play an important role in improving soil quality, inhibiting weed growth, promoting crop growth, etc. Rotary tillage is the first step in the tillage process. The rotating plow blades cut and break the soil, improving the soil structure, making it softer and more breathable, which is beneficial to the growth and development of crop roots. After rotary tillage, soil is returned and ridges are formed, that is, the soil is piled up into strip-shaped high platforms (ridge platforms) higher than the ground. Immediately afterwards, a plastic film is covered on the ridge platform, and the plastic film is covered on the rotary tilled soil. The purpose is to reduce the evaporation of soil moisture, maintain soil humidity, and improve the water retention capacity of the soil.
