Problems solved by technology

However, the stability of the compound microbial preparations currently used is not strong, and it is easily affected by the environment. The group structure may cause the death of a certain microorganism due to environmental changes or the group advantage of the compound microbial branch is changed due to the intervention of new microorganisms, and the current compound microbial The bacterial strain is single, and the fertilizer effect is unstable after compounding, so it is difficult to promote it on a large scale in practical applications

Abstract

The invention discloses a chain-type composite microbial agent and a preparation method thereof, and belongs to the technical field of fertilizer. Fertilizer is prepared from the raw materials of composite microbial agent, modified kieselguhr, activated humic acid, and medium trace elements; and the composite microbial agent is prepared from azotobacter chroococcum, bacillus megatherium, actinomycetes, bacillus licheniformis, photosynthetic bacteria, agritol and paecilomyces lilacinus according to the mass ratio of 1:3:3:1.5:1.5:1.8:1 in a mixed mode. An efficient and stable microbial flora isscientifically constructed, a complete chain system is formed among all bacterial strains, and the positive effect can be exerted from providing of nutrients to improvement of crop yield and quality;and the effect of microorganisms is exerted to the maximum limit, kieselguhr is modified structurally, the microorganisms are fully adsorbed, humic acid is activated, effective substance of the humicacid is promoted to be dissolved out, the microorganisms are assisted to exert the effect, and crop growth is promoted.

Description

technical field [0001] The technical field of fertilizers of the present invention specifically relates to a chain compound microbial bacterial agent and a preparation method thereof. Background technique [0002] Microorganisms are ubiquitous in nature, from as small as a single cell to as large as the Earth's biosphere. From land to sea, from aquaculture, animal husbandry to agriculture, from food industry, pharmaceutical industry to printing and dyeing, textile, tanning, etc., all industrial processes involving organic matter are closely related to microorganisms. They have the characteristics of tiny individuals, vigorous metabolism, wide distribution, and large quantities, and they also have strong decomposition capabilities. Their activities ensure the material cycle of the ecosystem, purify the ecosystem, and coordinate the ecological balance. [0003] Composite microorganisms are a type of microbial preparation products that have emerged at home and abroad in recent...
