Problems solved by technology

[0004] 1. The types of domestic microbial strains are relatively single, mostly Bacillus, which is widely used because of its convenient cultivation, cheap price and long shelf life, but the application effect is general; a single strain is rarely used as a fermented fertilizer because of its metabolites (mainly enzymes, that is, enzymes) are difficult to cope with the full fermentation of organic raw materials and mineral source raw materials (inorganic nutrition)
[0005] 2. Domestic compound microbial strain compounding technology is relatively simple, mostly based on simple multi-blending, without fully considering the interaction relationship between different microorganisms, which further leads to the

preparation example Construction

[0055] The preparation method of the bacterial liquid is as follows: the bacteria are cultured in the bacterial seed culture medium at 37°C for 24 hours; then cultivated in the bacterial shaker culture medium at 37°C and the shaker speed is 180r / min for 18 hours; finally in the bacteria Fermentation culture medium, 37 ℃, shaker speed is 180r / min under the fermentation culture for 36 hours, after the fermentation culture is completed, the mother liquor is obtained, which is the bacterial bacterial liquid. The spore production rate in the bacterial bacterial liquid is more than 90%, and the number of effective viable bacteria ≥5.0×10 9 cfu / mL;

[0056] Wherein, the composition of bacterial seed culture medium and bacterial shaker culture medium is identical;

[0057] Bacteria seed culture medium is: peptone 1%, yeast extract 0.5%, sodium chloride 1%, the rest is water, pH is 7.0;

[0058] The bacterial fermentation medium is: starch 5%, peptone 1.5%, sodium chloride 0.6%, the ...

Abstract

The invention relates to an agricultural composite microbial agent and a preparation method of same. The method is direct at defects in the prior art and includes a step of compounding bacteria, yeast, lactic acid bacteria, actinomycetes and filamentous fungus, so that the composite microbial agent has relative stability and reliability among the microorganisms, is high in fermentation efficiencyand can be preserved at normal temperature for long time. By means of the preparation method, the agricultural composite microbial agent can be processed in liquids or solid powders conveniently, final products having acidity. The product can resist infection of foreign bacteria, is free of refrigeration, is convenient to store and has long shelf life.

Description

technical field [0001] The invention belongs to the technical field of composite bacteria, and in particular relates to an agricultural composite bacteria agent and a preparation method thereof Background technique [0002] Agricultural compound bacterial agents refer to microbial preparations made of two or more microbial strains that are not antagonistic to each other and are used in agriculture. They are mainly used as components of biological compound fertilizers or as fermentation strains for agricultural fermentation. [0003] At present, there are mainly the following defects in agricultural fungicides: [0004] 1. The types of domestic microbial strains are relatively single, mostly Bacillus, which is widely used because of its convenient cultivation, cheap price and long shelf life, but the application effect is general; a single strain is rarely used as a fermented fertilizer because of its metabolites (mainly enzymes, i.e. enzymes) are difficult to cope with the ...
