If farmers want to increase organic fertilizer, they can adopt the following ways:
First, vigorously promote the return of straw. Straw returning is an important way to increase soil nutrients, increase soil organic matter content, improve soil physical and chemical properties and potassium, phosphorus nutrition conditions, and enhance soil microbial and enzyme activities.
In particular, in recent years, grass cover in early rice cultivation, late rice no-tillage cultivation techniques, and wheat, rapeseed, milk vetch, and early crop cover techniques have not only adapted to the characteristics of current agricultural production, but have also been able to increase grass growth. , moisturizing with grass, regulating temperature with grass, protecting soil with grass, grazing grass with grass, working with the province and other multiple effects, both organic fertilizer, biological film and soil protection of the multiple advantages of vegetation. This technology not only has the basic characteristics of traditional agriculture, but also has the characteristics of modern agriculture, has a strong vitality and broad prospects for development.
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 a bond between agriculture and animal husbandry. The nitrogen resource contained in the green manure is present in the form of protein, which can directly provide the necessary source of protein for humans and livestock, and is a good animal husbandry feed. To develop green manure production, we must take the road of grain fertilizer, vegetable fertilizer, and forage fertilizer, and increase the direct economic benefits of green manure in order to fully display the strong vitality of green manure in agricultural production.
The third is to improve the utilization of manure and manure. The preservation, accumulation and application of farm manure have a long history in China. In the 1960s, the farmers were summed up as “four fields†(industrious sweeps, ground mats, diligence, and diligence) and “eight ares†(cattle There is still no outdated experience in the columns, the pigs have laps, the ash houses, the manure pools, the people have toilets, the chickens and ducks have earth temples, the seasons have dung, the fields have green manure). We must further carefully summarize these traditional traditions. Experience, and gradually increase, continue to flourish.
Fourth, vigorously promote commodity organic fertilizers. Since the beginning of the 21st century, refined organic fertilizers and organic-inorganic compound fertilizers have become "newcomers" in the fertilizer industry. Looking ahead to the development trend of fertilizers in this century, organic fertilizers will be applied to soils in the form of commodity organic fertilizers and organic-inorganic compound fertilizers, in addition to being returned to the farmland directly or after treatment. With the continuous increase in the demand for organic fertilizers for green food production, organic-inorganic compound fertilizers will gradually develop into organic fertilizers, transporting a small amount of inorganic fertilizers to organic fertilizers, and regulating the nitrogen in organic fertilizers. Phosphorus, potassium ratio or increase the available nitrogen in organic fertilizers to give full play to the role of organic fertilizers.
The application of organic fertilizers is a combination of traditional agricultural technology and modern agricultural science and technology. It is the relationship between inheritance and development. It is also the best way to recycle the use of substances in the production and living processes. Only manure and fertilizers are used, and fertilizers can be used. To achieve the purpose of enhancing land.
