Description

Technical Field

[0001] The utility model relates to the technical field of straw stubble crushing and scattering, in particular to a straw stubble crushing and scattering device. Background Art

[0002] Returning straw to fields, a common agricultural practice, is a globally recognized measure for improving soil fertility and increasing yields. While eliminating air pollution caused by straw burning, it also increases soil fertility and yields. Returning straw to fields increases soil organic matter, improves soil structure, loosens soil, increases porosity, reduces soil volume, and promotes microbial activity and the development of crop roots. Returning straw to fields significantly increases fertility and yields, typically by 5% to 10%. Straw spreaders are often used during this process.
