Fermentation system and preparation method for preparing high-efficiency bio-organic fertilizer from organic materials

technical field

The invention belongs to the technical field of organic fertilizer preparation, and in particular relates to a fermentation system and a preparation method for preparing high-efficiency bio-organic fertilizer from organic materials.

Background technique

Agriculture is dominated by aquaculture and planting. In planting, a large amount of crop straw will be produced. People can only choose to stack or burn it. However, burning straw will cause harm to human body, air, soil, traffic safety, life and property. The open-air burning of straw directly leads to air pollution. In summer and autumn, due to the mass burning of straw, the number of suspended particles in the air increases significantly, and the burning produces a large amount of harmful gases such as carbon monoxide and carbon dioxide, which reduces the quality of the atmospheric environment. The burning of straw causes the ground temperature to rise sharply, which can directly burn and scald the beneficial microorganisms in the soil, affect the full absorption of soil nutrients by crops, and directly affect the yield and quality of farmland crops. In the breeding industry, a large amount of animal manure will be produced, and the direct discharge of animal manure will have an impact on the environment.
