Significance of biofertilizer production
in treating straw manure
Bio-organic fertilizer has comprehensive nutrition, rich in organic matter, humic acid, amino acid and nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, zinc, copper, boron, manganese, iron and other elements. Among them, organic matter, humic acid and amino acid can continuously release nutrient elements needed for plant growth through microbial activities, which can regulate plant growth, help crop root development, and promote stable and high yield of agriculture.
Biofertilizer can improve the quality of crops. Nitrate is one of the important pollutants that endanger human health. The application of biomass organic fertilizer can significantly reduce the nitrate content in crops.
1. Fermentation and decomposition of chicken manure, pig manure, cow manure, straw, mushroom residue and other materials.
2. Crushing of Decomposed Material
3. Organic Fertilizer Granulation
5. Particle screening
Compared with general organic fertilizer processing, microbial agents should be added to the production of biofertilizer. In the compounding stage of biofertilizer production process, proper amount of microbial agent was added, and the raw material was stirred evenly, then it was sent to the flat die extrusion granulator. Flat die extrusion granulator can effectively retain beneficial ingredients and not destroy the efficiency of biofertilizer because of the way of material granulation by die extrusion, and the temperature rise during granulation is not obvious. Moreover, the granules of the flat die granulator are cylindrical, with adjustable length, high hardness and low water content, which can save energy consumption such as drying and save energy.
The production of biological fertilizers is of great significance for the treatment of agricultural waste and the cultivation of manure waste. The fertilizer manufacturing process not only can solve the straw treatment, reduce the straw burning and waste, but also has high value of the biological fertilizer product, which can increase the soil organic matter content, improve the quality of agricultural products, and the agricultural effect is remarkable.
