Agricultural composite microbial preparation and preparing method thereof

Abstract

The invention discloses an agricultural composite microbial preparation, respective zymocyte solutions of soja bean legume bacteria, round brown azotobacteria, bacillus megaterium and colloidal substance bacillus are respectively adsorbed on the adsorbing agent according to the proportionality of 15-20 % by weight to prepare soja bean legume bacteria, round brown azotobacteria, bacillus megaterium and colloidal substance bacillus, which are compounded to the agricultural composite microbial preparation; the invention adopts the composition of four kinds of bacterial seeds, also considers the requirement ofnitrogen, phosphor and kalium nutrients for plant, it is proved by the field experiment, the obvious yield increasing and quality raising actions for multiple corps are provided; the method accelerates the growth respectively adopting the controls of air flow of microorganism, temperature and inoculating amount during fermentation, enables the fermentation periods of the four kinds of composite bacterial series to be shortened, thereby fermenting at the same time and the terminating at the same time.

Description

Technical field [0001] The invention relates to an agricultural fertilizer, in particular to an agricultural composite microbial inoculum and a preparation method thereof. Background technique [0002] Nitrogen, phosphorus, and potassium are the three essential elements for plant growth. Phosphorus and potassium in the soil are in the form of organic or inorganic phosphorus and potassium compounds. Plants can’t directly absorb and utilize them. Through Bacillus megaterium, which can dissolve phosphorus, and Bacillus glaciens, which dissolve potassium, the phosphorus that is difficult for plants to absorb can be separately absorbed. And potassium is converted into phosphorus and potassium which can be directly used by plants. The molecular nitrogen in the air cannot be absorbed by plants. Through the symbiotic nitrogen fixation of rhizobia and the autogenous nitrogen fixation of Azotobacter chroococcus, the molecular nitrogen is converted into ammonia for direct absorption and uti...

AI Technical Summary

Problems solved by technology

[0003] At present, the strains of the compound bacterial agent are generally combined with two or three of them. Since the fermentation cycles of these four bacteria are greatly different, it is difficult to complete the fermentation of the four bacteria at the same time in production, so it is difficult to simultaneously adsorb on the adsorption. agent, and then mix in proportion

The problem is that every single bacterial agent that is prepared first is first packed in a turnover bag, and then mixed in proportion after the other three are produced one after another.

The single bacterial agent produced in this way is easy to be contaminated with bacteria and dry because it is stored in the turnover bag, and it is easy to dry out, which affects the quality of the final product

In addition, each time a type of bacteria is produced, it must be packaged once, and then unpacked, mixed, and repackaged. There are several more processes, which will increase the production cost and production cycle.
