is conducive to improving soil organic matter and fertility, and improving soil physical and chemical environment and microbial environment. However, if the manure is not composted and decomposed directly into the field, it will consume the oxygen in the soil, resulting in high temperature, burn the roots of crops, produce pathogenic bacteria and harmful substances, not only can not increase production, but also lead to soil, water, air and agricultural products secondary pollution. Therefore, cow manure must be composted, stable and harmless before it can be used.

The production process of organic fertilizer granulator: the raw materials are poured into the organic fertilizer mixer and mixed, mixed evenly and crushed, and input thepelletizing tray with the belt conveyor; After pelletizing, it is sent to the dryer for drying, transported to the cooling machine through the elevator or belt conveyor for cooling, the water reaches below 6%, after cooling, it is screened, the large particle material is crushed into fine material by the return crusher, the fine material enters the disk granulator, the coarse return material enters the granulator after crushing, and the finished product is packaged directly. Organic fertilizers enhance crop resistance and reduce or prevent disease. After applying organic fertilizer into the soil, it can enhance the water storage capacity of the soil, enhance the drought resistance of crops in the case of drought, and also make the soil loose, improve the ecological environment of crop roots, enhance root vitality, increase crop tolerance, reduce plant mortality, and improve the survival rate of crops.
