Description

Technical Field

[0002] Against the backdrop of global advocacy for sustainable development, the resource utilization of agricultural waste has become an important part of achieving a green circular economy in agriculture. Crop straw, as a major by-product of agricultural production, comes from a wide range of sources and is produced in large quantities. According to statistics, my country produces hundreds of millions of tons of crop straw each year. However, due to the lack of efficient and reasonable treatment methods, a large amount of straw has long faced many problems, such as burning causing environmental pollution, arbitrary stacking occupying land, and breeding mosquitoes. Decomposing straw into organic fertilizer can not only reduce environmental pollution, but also effectively improve soil fertility and promote the sustainable development of agriculture. Therefore, straw decomposition technology has attracted much attention. The efficiency and quality of straw decomposition are closely related to straw pretreatment, and crushing is a key step in straw pretreatment.
