Method for preparing organic bacteria liquid, organic bacteria liquid prepared by method and application of organic bacteria liquid

Abstract

The invention discloses a method for preparing organic bacteria liquid, the organic bacteria liquid prepared by the method, and an application of the organic bacteria liquid. The organic bacteria liquid is prepared by breeding bacteria from industrial and agricultural wastes which are rich in organic materials, such as plant ash, furfural residue, excrement, activated sludge, and crop straw, and screening, expanding and propagating the bred bacteria. The organic bacteria liquid has the characteristic of high bacterial activity, and can be used as a mother culture in the production of a microbial fertilizer or directly used as a seed-dressing agent.

Description

technical field [0001] The invention relates to an organic bacterial liquid for biological bacterial fertilizer, belonging to the field of microbial fertilizers. Background technique [0002] With the adjustment of my country's rural economic structure and the acceleration of agricultural industrialization, the discharge of industrial and agricultural waste such as biogas residue, plant ash, furfural residue, and animal manure has increased significantly. According to the pollution survey conducted by the National Environmental Protection Agency: In 2010 alone, the national discharge was 1.9 billion tons, 2.4 times that of industrial solid waste (780 million tons) in the same year, and COD emissions reached 71.18 million tons, which greatly exceeded industrial waste water and domestic waste. The sum of COD emissions from wastewater. This has seriously led to the deterioration of the rural ecological environment. It not only pollutes the air, water and soil, but also breeds ...

Problems solved by technology

Some strains perform well under laboratory conditions, but when actually producing fertilizers or using them in farmland, due to differences in the environment, the survival rate may be low, and it is difficult to achieve the desired effect after use.

In addition, in the prior art, compound strains (2-3 bacterial strains that do not produce antagonistic effects) are also used to produce fertilizers, but using compound strains is a relatively complicated problem, and it cannot be simply considered that the compounding (or combination) of microorganisms ) is the mixed fermentation of many bacteria, or simply mixed and combined after fermentation

The temperature, moderateness, pH and other indicators required for the growth of various strains are different, and there may be antagonism between them, which may cause the effect of the compound strain to be unsatisfactory.
