The application of organic fertilizer production lines in green breeding methods can not only effectively handle waste such as livestock and poultry manure, but also achieve the recycling of resources and promote the sustainable development of agriculture. The following are the specific application methods and advantages:

Waste resource utilization: Through the organic fertilizer production line, livestock and poultry manure is transformed into high-quality organic fertilizer, achieving the resource utilization of waste and reducing environmental pollution.

2. Soil improvement and fertility enhancement: Organic fertilizers can significantly improve the physical properties of the soil, increase soil aggregate structure, and enhance the soil's water and nutrient retention capacity.

3. Reduce reliance on chemical fertilizers: By using organic fertilizers, reliance on chemical fertilizers can be reduced, and greenhouse gas emissions generated during the production, transportation and application of chemical fertilizers can be lowered. The combined use of organic and chemical fertilizers can enhance the utilization rate of fertilizers and reduce nutrient loss.

4. Promoting sustainable agricultural development: Organic fertilizer production lines reduce greenhouse gas emissions by optimizing fermentation processes and the operation of organic fertilizer equipment. The application of organic fertilizers conforms to the requirements of low-carbon agricultural development and helps achieve the goals of "carbon peak and carbon neutrality".

5. Promote green breeding models: Build an ecological circular model to achieve multi-level utilization and transformation of resources. Through the organic fertilizer production line, waste such as livestock and poultry manure is converted into organic fertilizer, reducing environmental pollution during the breeding process.

Through the application of organic fertilizer production lines, not only can agricultural waste be effectively treated and environmental pollution reduced, but also soil quality can be improved, promoting the sustainable development of agriculture and achieving a win-win situation of economic and environmental benefits.
