The higher the yield of the crop, the more nutrient nutrients are obtained from the soil, and it is necessary to compensate the soil nutrients in the form of fertilization, especially in fertilizer. With the increasing application of chemical fertilizers, the proportion of organic fertilizers in fertilizer structures is relatively decreasing, and the dependence of agricultural production on fertilizers is increasing. Under certain conditions, the seasonal increase of fertilizer application is indeed very large. With the gradual increase of single fertilizer application, the soil organic matter consumption also increases, causing the decomposition of soil aggregate structure and the ability to coordinate water, fertilizer, gas and heat. Decline, soil fertility and fertilizer performance deteriorate, and new low-yield fields will emerge. Formula fertilization must achieve the two purposes of exerting soil fertility and fertilizing soil. It is impossible to rely solely on chemical fertilizers, and organic fertilizer must be added. The role of organic fertilizer, in addition to supplying crops with multiple nutrients, is more important to renew and accumulate soil organic matter, promote soil microbial activities, facilitate the formation of soil aggregate structure, and coordinate soil fertility factors such as water, fertilizer, gas and heat. Enhance soil fertility and fertilization capacity, and create conditions for high yield and quality of crops. Therefore, formula fertilization is not a simple ratio of several fertilizers. It should be based on organic fertilizer, nitrogen, phosphorus, potassium fertilizer and medium and trace elements combined to obtain high quality and high yield of crops, and maintain and improve soil fertility.
