Straw deep burying and returning method and device

Abstract

Provided are a straw deep burying and returning method and device. The method includes the following steps of firstly, conducting picking and pulverizing through a deep burying and returning device; secondly, breaking original ridges into furrows through a ditching plow in the device after picking and pulverizing are completed, meanwhile making a deep burying plow in the device go deep into furrowbottom layers, and scattering pulverized straw discharged from a feeding box into a plow cavity of the deep burying plow onto the furrow bottoms through a deep burying conveyer so that the deep burying of the straw can be completed and the formed furrows can serve as the furrows for the tillage in the next season; thirdly, making loose soil on the upper side and the two sides intermediately falland converge to evenly bury the straw scattered on the furrow bottoms when the deep burying plow passes through the soil in the furrow bottoms, and combining original furrows into ridges as the foundation parts for the plantation in the next season. By means of the method and device, the alternate straw pulverizing and deep burying operation is conducted, the problems in an existing straw pulverizing and burying technology are successfully solved, and the straw returning method is efficient.

Description

technical field [0001] The invention relates to a method and a device for crushing and deeply burying straw and returning it to the field. Background technique [0002] For a long time, the utilization rate of crop straw has been low, and it is usually directly discarded in the farmland or burned on the spot. This not only easily creates a fire hazard, endangers the safety of people's lives and property, but also causes a great waste of resources, and also produces serious pollution to the ambient air. It also destroys the soil structure. In recent years, all agricultural planting relies on chemical fertilizers to provide nutrients for plant growth, and the amount of farm manure is almost zero, which is a predatory production, so that the humus in the soil is absorbed by the growing plants year after year, causing the original black soil to gradually turn into yellow soil. , the phenomenon of soil compaction and desertification is serious. In addition, the methods of retur...

AI Technical Summary

Problems solved by technology

2. In addition, the straw on the ground surface is not uniform, and the burial amount cannot be uniform without storage and buffering

3. When the straw is relatively concentrated or the amount of straw is naturally large, the straw will not be buried in the soil but will be exposed on the ground surface

4. High power consumption during burial

5. Part of the burial will affect the growth of plants in the next season
