To develop ecological agriculture and develop and produce pollution-free “organic food”, the fertilization technology in agricultural production must be reformed, that is, to apply fertilizer reasonably, to follow the development path of organic-inorganic combination application, and to vigorously develop organic fertilizer. Benefits of using organic fertilizer:
1、 Improve soil and improve soil fertility: after applying organic fertilizer into the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, ripen the soil, enhance the ability of fertilizer conservation and supply and buffer capacity of the soil, and create good soil conditions for the growth of crops.
2、 Improve product quality and increase yield: organic fertilizer is rich in organic matter and various nutrient elements to provide nutrition for crops. After the decomposition of organic fertilizer, it can provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate the decomposition of organic matter, and produce active substances that can promote the growth of crops and improve the quality of agricultural products.
3、 Improve the utilization rate of fertilizer: organic fertilizer contains a lot of nutrients and releases slowly. The organic acid produced by the decomposition of organic matter can also
