　　
For farmers to increase the application of organic fertilizer, the following ways can be achieved:
　　
First, vigorously promote the return of straw to the field. Straw returning is an important way to increase soil nutrients, increase soil organic matter content, improve soil physical and chemical properties, potassium and phosphorus nutrient conditions, and enhance soil microbial and enzyme activities.
Especially in recent years, the early straw cultivation, the late rice no-till cultivation techniques, the wheat field, rapeseed, Chinese milk vetch and the early crop cover grass technology not only adapt to the characteristics of current agricultural production, but also play the role of grass and fattening. It has multiple functions such as moisturizing grass, adjusting grass with grass, protecting grass with grass, pressing grass with grass, and saving labor. It has multiple advantages of organic fertilizer, biofilm and soil protection vegetation. This technology not only has the basic characteristics of traditional agriculture, but also has the characteristics of modern agriculture, with strong vitality and broad development prospects.
　　
The second is to vigorously develop economic green manure. The development of green manure production is an effective way to increase organic nitrogen sources and enrich phosphorus, potassium and trace elements in soil. At the same time, green manure is the link between agriculture and animal husbandry. The nitrogen resources contained in green manure exist in the form of protein. It can directly provide the source of protein necessary for humans and animals, and is a high-quality livestock feed. To develop green manure production, it is necessary to take the road of grain and fertilizer, vegetable fertilizer and fertilizer, and improve the direct economic benefits of green manure to fully demonstrate the strong vitality of green manure in agricultural production.
　　
The third is to improve the utilization rate of manure and manure. The preservation, accumulation and application of farmyard manure have a long history in China. In the 1960s, the “four diligences†(diligence sweep, diligence, diligence, diligence) and “eight haves†(bovines) The experience of the bar, the pig has a circle, the gray house, the manure pool, the people have the toilet, the chicken and duck have the soil temple, the season has the manure, the field has the green manure, and the experience is still not outdated. We must further carefully summarize these traditional Experience, and gradually improve, continue to carry forward.
　　
The fourth is to vigorously promote the commercial organic fertilizer. Since the beginning of the 21st century, refined organic fertilizers and organic-inorganic compound fertilizers have become "newcomers" in the fertilizer industry. Looking forward to the development trend of fertilizers in this century, organic fertilizers will be applied to the soil in the form of commercial organic fertilizers and organic-inorganic compound fertilizers, except directly or after being treated and returned to the farmland. With the increasing demand for organic fertilizers in green food production, organic-inorganic compound fertilizers will gradually develop to organic fertilizers, and a small amount of inorganic fertilizers will be transported to the concentration of organic fertilizer resources to regulate nitrogen in organic fertilizers. Phosphorus, potassium ratio or increase of available nitrogen in organic fertilizers to fully play the role of organic fertilizers.
The application of organic fertilizer combines traditional agricultural technology with modern agricultural science and technology. It is the relationship between inheritance and development. It is also the best way to recycle materials in production and life. Only multi-fertilizer fields can be used with fertilizer. Achieve the purpose of enhancing the ground force.
