Microbial enzyme compound bacterium fertilizer for organic planting soil improvement and preparation method of fertilizer

Abstract

The invention discloses a microbial enzyme compound bacterium fertilizer for organic planting soil improvement and a preparation method of the fertilizer. The microbial enzyme compound bacterium fertilizer is prepared from organic fertilizers and microbial enzyme preparations, wherein the organic fertilizers comprise livestock manure and brown coal, and the microbial enzyme preparations comprise nearly hundreds of microbial enzymes belonging to 8 families and 12 genera. Humic acid can be obtained by biochemical reaction, the content of organic matters is effectively increased, soil can be improved, high nitrogen, phosphorus and potassium components can be supplemented, fertilizer effects are improved, and the microbial enzyme compound bacterium fertilizer is an excellent product replacinga chemical fertilizer. The stress resistance of crops can be enhanced, bacteria are inhibited by bacteria to inhibit soil-borne diseases, yield is increased, quality is improved, and economic benefitsare increased.

Description

Technical field [0001] The invention relates to a microbial enzyme compound bacterial fertilizer for soil improvement of organic planting and a preparation method thereof. Background technique [0002] At present, the world is facing serious problems of population increase and environmental degradation, and the extensive use of inorganic fertilizers in agricultural production will also make environmental degradation more serious. The main shortcomings of this inorganic fertilizer are: damage to the soil, resulting in a decrease in the content of soil organic matter, imbalance of various nutrients, soil acidification and compaction, and severe damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention and preservation. Fertilizer and air permeability are poor, and it is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increa...

AI Technical Summary

Problems solved by technology

The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year; After farmland, the actual utilization rate is only 30% on average, and most of it flows into rivers and lakes with farmland drainage or remains in the soil, plants and crops, which not only brings environmental pollution but also endangers the safety and health of human beings and lives. These have become sustainable agriculture. Obstacles to sexual development; the above conditions can be improved by applying organic fertilizers, but there are many varieties of organic fertilizers in China. The content of nitrogen, phosphorus and potassium is high, but the organic matter is insufficient, and the amount of application is very small, so it cannot be used as the main fertilizer, and the effect is single, and the price is high
