And a large amount of fertilizers are applied to farmlands, the actual utilization rate is about 30 percent, most of the fertilizers flow into rivers and lakes along with rainwater or farmland drainage, and the fertilizers are also one of the main factors causing water quality eutrophication pollution. The organic fertilizer can effectively improve the physical and chemical conditions and biological characteristics of soil, enhance the water retention, fertilizer retention and fertilizer supply capacities of the soil, and improve the quality and yield of crops on the soil with high organic matter content. However, the existing common organic fertilizer is derived from organic wastes, such as wheat bran, kitchen waste, rice straw, bagasse and the like. However, these organic substances cannot be directly used by crops and must be subjected to a process of decomposition. The decomposed organic fertilizer has lower nutrient content and slower nutrient release, and the preparation time is relatively longer due to the long time of the composting decomposition process, so compared with chemical fertilizers, the manufacturing cost of the organic fertilizer is higher.
