Organic inorganic compound fertilizer and production technology thereof

Abstract

The invention discloses an organic inorganic compound fertilizer, which comprises microbial functional flora amplification liquid and a fermentation raw material. The fermentation raw material comprises following raw materials in parts by weight: 20 to 30 parts of potassium ore powder with a size of 120-1200 meshes, 20 to 30 parts of phosphorus ore powder with a size of 80 meshed, 35 to 45 parts of nitrogen enriched organic substance, 5 to 10 parts of grass carbon powder with a size of 50 meshes, 2 to 5 parts of calcium oxide with a size more than 120 meshes, and 1 to 4 parts of zeolite with asize of 80 meshes, wherein the nitrogen enriched organic substance is one or more of soybean meal powder, bacterial protein, amino acid powder, fish meal, and feather powder. The compound fertilizerhas the advantages that nutrients are directly extracted from natural mineral powder, the chemical refining process is avoided, the whole production process is green, clean, and environmentally friendly, and the fertilizer can promote the growth of crops effectively. Low grade natural potassium / phosphorus ores are taken as the main raw materials, the raw material sources are wide, the cost is low,and the problem that low grade ores are difficult to use in industry is solved.

Description

technical field [0001] The invention relates to a fertilizer production process, in particular to a production process of organic-inorganic compound fertilizer. Background technique [0002] At present, the extensive use of chemical fertilizers has drawn more and more attention to the safety of food, the protection of the ecological environment and the sustainable use of resources, which are related to human life and health. Microbial fertilizers can fertilize soil fertility, improve the utilization rate of chemical fertilizers, and reduce the pollution of chemical fertilizers to the environment. Existing chemical fertilizers (one or more of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer) are mixed with organic fertilizers to produce, so that the fertilizer has both a certain amount of nitrogen, phosphorus and potassium and a certain amount of organic matter. Chemical fertilizers are still the basic raw materials used in the existing organic-inorganic c...

AI Technical Summary

Problems solved by technology

Chemical fertilizers are still the basic raw materials used in the existing organic-inorganic compound fertilizers, and there is still some pollution after being applied to the soil, and as industrial products, the cost of chemical fertilizers is relatively high, and the combination of inorganic fertilizers and organic fertilizers is unreasonable. , the defect of incomplete nutrient composition may easily cause the waste of nutrient composition and the decline of soil fertility

[0003] In summary, the existing organic and inorganic fertilizers have the defects of high production cost, unreasonable nutrient combination, incomplete nutrient content, environmental pollution, and reduced soil fertility, which need to be further improved.
