Method for preparing microbial organic bacterial manure

Abstract

The invention provides a method for preparing a microbial organic bacterial manure. The method comprises the following steps: S10. carrying out primary composting: after bone shell raw materials in an organic raw material are crushed into powder, adding activated carbon and BEST bacterial mixtures to compost; step 20. carrying out secondary composting: adding non-bone-shell materials in the organic raw material, biogas residues of animal dung subjected to biogas fermentation and the BEST bacterial mixtures into the product subjected to the primary composting to conduct the secondary composting, wherein the organic raw material is one or multiple of dry branches and fallen leaves, food and feeds, barks, kitchen garbage, animal dung, crop straws and household garbage. The organic bacterial manure prepared by the method for preparing the microbial organic bacterial manure can change the physical, chemical and biological properties of soil, can keep the soil loose, can promote formation of soil aggregate structures so as to improve the permeability of the soil, and can provide crops with the good soil environment so as to cause plants to strongly grow.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizer, in particular to a method for manufacturing microbial organic fertilizer that does not contain harmful pathogenic bacteria and can activate soil. Background technique [0002] Organic fertilizers include plant fertilizers, animal (including their excrement) fertilizers and their mixtures; in short, organic fertilizers are organic fertilizer materials that can increase the content of soil organic matter when added to the soil. Unlike chemical fertilizers, which are composed of inorganic elements, organic fertilizers are made from human and animal manure, agricultural waste (such as straw, chaff, discarded leaves) or green manure crops, which are actually a mixture of organic and inorganic substances. The living microorganisms transform the inanimate material into the nutrients needed for the growth of various crops. It can improve the soil, activate and resuscitate the soil, and has ...

AI Technical Summary

Problems solved by technology

[0003] Most of China's agricultural plantations today use chemically synthesized inorganic fertilizers, such as the most common potassium oxalate, etc., which basically provide nutrients for crops in the form of inorganic salts, but the above inorganic fertilizers are easily fixed by lime and silicate ions in the soil , lead to soil compaction, and also make the environmental pollution increasingly serious, heavy metals, chemical residual toxins, etc. are enriched in the soil

[0004] In order to improve the above problems, there are currently some organic fertilizers, similar to the practice of traditional Chinese agriculture, such as litter, food feed, bark, kitchen waste, animal excrement, etc. are used as organic fertilizers, but these fertilizers contain relatively A lot of putrefactive bacteria, pathogenic bacteria, and organic protein, etc., can easily lead to a large number of mosquitoes and flies. Although it has the effect of fertilizer, the environment is more unsanitary, and crops are more likely to suffer from disease and reduce production.
