The straw crusher has a remarkable effect in environmental protection, mainly reflected in the following aspects:

Reduce air pollution: Traditional straw burning generates a large amount of harmful gases, such as carbon dioxide (CO₂), carbon monoxide (CO), etc., which have a serious impact on air quality. The straw chopper effectively avoids air pollution caused by burning by crushing straw and returning it to the field.

2. Enhance soil fertility: Returning crushed straw to the field can significantly increase the organic matter content in the soil, improve soil structure, and enhance the soil's water and nutrient retention capacity.

3. Resource recycling: The crushed straw can be used as raw material for organic fertilizer. Through composting treatment, the organic matter content in the soil can be further increased, promoting crop growth. After being crushed, straw can also be used as raw material for biomass energy, for biomass power generation or heating, achieving the recycling of resources.

4. Reduce soil erosion: After straw is crushed and returned to the field, it can improve the soil aggregate structure, enhance the soil's resistance to erosion, and reduce soil erosion.

5. Reduce the risk of pests and diseases: Uncomposted straw may carry pests and diseases. By crushing and returning it to the field and taking appropriate management measures, the risk of pest and disease occurrence can be reduced.

6. Policy support and economic benefits: The national and local governments have introduced a series of policies to support the comprehensive utilization of straw, providing subsidies for the purchase of organic fertilizer equipment and the construction of collection and storage systems. Straw crushing and returning to the field can reduce the use of chemical fertilizers and lower production costs.

Through the above measures, the straw chopper can not only effectively reduce environmental pollution, but also enhance soil fertility and promote the sustainable development of agriculture.
