Description

Technical Field

[0001] This utility model relates to the field of deep burial and returning of fresh straw to the field, and in particular to a device for deep burial and returning of rapeseed fresh straw to the field. Background Technology

[0002] Fresh rapeseed straw is a rich source of organic matter, such as carbon, nitrogen, phosphorus, and potassium. By deeply burying it and returning it to the field, these nutrients can be effectively introduced into the soil, providing nutrients for crop growth. Deep burial and returning it to the field helps increase the organic matter content of the soil, improve soil structure, and enhance the soil's water and fertilizer retention capacity.

[0003] Currently, when using existing rapeseed straw deep burial equipment, the rapeseed straw has many branches, and some branches are thin and hard. When returning the rapeseed straw to the field, the branches may not be cut continuously, resulting in the branches remaining connected. This connection of branches and stems will prevent the straw from being fully mixed with the soil, affecting the decomposition speed of the straw. Utility Model Content
