If farmers want to increase organic fertilizer, they can use the following ways to implement straw return.
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 development of economic green manure to develop 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.
Raising the utilization rate of manure and livestock manure The preservation, accumulation and application of farm manure have a long history in China. In the 1960s, the farmers summarized the “four diligence†(industrious sweeping, diligence, diligence, and diligence), “ There is still no outdated experience in the eight “has†(cows, pigs, ash, houses, dung, people have toilets, chickens and ducks have earth temples, seasons have dung, there is green manure in the field), we want to further Seriously sum up these traditional experiences and gradually increase them to continue to carry forward.
Since the promotion of commodity organic fertilizers into 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 soil in the form of commodity organic fertilizers and organic-inorganic compound fertilizers, in addition to returning them 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 to organic fertilizers. A small amount of inorganic fertilizers will be transported to the concentrated organic fertilizer resources to regulate nitrogen and phosphorus in organic fertilizers. , Potassium ratio or increase the available nitrogen in organic fertilizers to give full play to the role of organic fertilizers.
The application of organic fertilizer 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 can be used to manage fertilizers. To achieve the purpose of enhancing land.
Mushrooms such as shiitake mushrooms, mushrooms, and black fungus not only taste delicious, but also contain higher protein than ordinary vegetables, and also contain a variety of trace elements, vitamins, etc., which is a very good type of nutritional food.Mushrooms are one of the familiar "mountain treasures". To obtain this reputation, mushrooms are not only dependent on taste, but also related to their rich nutrition and excellent health care value.
