Nowadays, the social pollution is becoming more and more serious, and there are more and more kinds of pollutants, such as agricultural waste, livestock manure, industrial waste, domestic garbage, and urban sludge. How to make rational use of organic fertilizer aerobic fermentation tank to innocuously treat these pollutants into organic fertilizer and return them to the soil, improve the land fertility, and ensure the quality of life and ecological breeding is a huge problem currently facing. However, long-term unreasonable use of chemical fertilizer in farmland is likely to cause imbalance in the proportion of nutrients in land and farmland, damage the farmland ecology, and affect the quality and safety of agricultural products.
Livestock and poultry dung: such as chicken dung, cattle, sheep, horse dung, rabbit dung;
Industrial wastes: such as distiller's grains, vinegar grains, cassava residues, sugar residues, furfural residues, etc;
Domestic waste: such as kitchen waste;
Urban sludge: such as river sludge, sewage sludge, etc. Classification of organic fertilizer raw material production and supply bases: silkworm excrement, mushroom residue, kelp residue, phosphocitric acid residue, cassava residue, protein mud, sugar formaldehyde residue, amino acid humic acid, oil residue, plant ash, shell powder, etc., and peanut shell powder.
Agricultural wastes: such as straw, soybean meal, cotton meal, etc.
Organic fertilizer, commonly known as farmyard manure, refers to slow acting fertilizer containing a lot of biological substances, animal and plant residues, excreta, biological waste and other substances. The organic fertilizer not only contains the necessary macroelements and microelements for plants, but also contains rich organic nutrients. The organic fertilizer is the most comprehensive fertilizer.
Organic fertilizer is organic solid waste decomposed by aerobic microorganisms in the organic fertilizer aerobic fermentation tank, which generates a large amount of heat with a temperature of more than 70 degrees, effectively killing bacteria and grass seeds in the waste, and produces organic fertilizer after complete decomposition. The organic fertilizer can be directly used for economic crops such as orchard, agricultural and vegetable bases, and can also be added with a certain proportion of chemical fertilizer, A compound fertilizer containing a certain proportion of organic matter that is fully mixed and granulated by technology.
