At present, of the total nutrient input of farmland fertilization in China, about 1 beat 4 of nitrogen, 1 of 3 of phosphorus, 80% of potassium and more than 90% of trace elements are solved by the application of organic fertilizer, which is an important basis for the sustainable development of modern agriculture. A large number of studies and practices show that organic fertilizer has comprehensive nutrients and long-lasting fertilizer effect. Organic fertilizer not only contains a large number of essential elements and trace elements, but also rich in organic nutrients. Organic fertilizer is the most comprehensive fertilizer. Organic fertilizer can improve soil physical and chemical properties, improve soil fertility and promote the activity of soil microorganisms. Organic fertilizer can be applied on the spot with wide sources and low cost. the application of organic fertilizer can not only increase nutrients, improve soil fertility, improve the utilization rate of chemical fertilizer, but also reduce the amount of chemical fertilizer, thus reducing the cost of fertilization. it is one of the important measures to save cost and increase efficiency in agriculture. In the guiding ideology, the application of organic fertilizer should be emphasized as much as chemical fertilizer, and the two should be applied together to complement each other, so as to achieve a reasonable structure and a balance between supply and demand. In the application method, it is mainly used as base fertilizer, combined with ploughing and ploughing the whole layer. Mature high-quality agricultural fertilizer and plant ash can also be used as topdressing to promote the direct return of crop straw to the field. In terms of fertilizer sources, it is necessary to make full use of human manure and urine, livestock and poultry manure, crop straw, weeds, fallen leaves and all wastes from agricultural production, make full use of plant ash, soil manure and cake fertilizer, and expand the planting area of green manure according to local conditions.
