Microbial agent and soil modifying agent produced by fermentation thereof

Abstract

The invention relates to a microbial agent used for producing a soil modifying agent by fermentation, consisting of fiber monad, bacillus, lactobacillus, methanobacteria, thiobacillus, streptomycete, high-temperature actinomyces, high-temperature monad, azotobacteria, nitration monad, nitration bacilus, rhizobium, koji mold, leaven, blue mold, detritus mold, rhizopus as well as mycorrhizal fungi and substrate. In addition, the invention also relates to a soil modifying agent produced by the fermentation of the microbial agent, application thereof and the like.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation. Specifically, the present invention relates to a soil conditioner used for fermenting and producing organic fertilizers. The stability and adaptability of the fermentation are good, and the soil conditioner produced by fermentation can improve soil fertility, It has excellent performance in reducing the content of harmful elements, eliminating pesticide residues, or improving saline-alkali land. In addition, the present invention also relates to a soil conditioner produced by fermentation of the above-mentioned microbial agent and its application. Background of the invention [0002] At present, as people pay more and more attention to health and food safety, the quality requirements of agricultural products are getting higher and higher. It is hoped that on the basis of increasing the production and income of agricultural products, the residues of chemical fertilizers in agricultu...

Problems solved by technology

[0004] However, in production practice, especially in large-scale production, the microbial compounding ability in these prior art microbial inoculum agents is insufficient

Even for the fermentation of organic fertilizers, due to the raw materials of organic fertilizer fermentation, such as animal manure and plant fibrous waste, due to different sources and different batches, the carbon and nitrogen content, pH value, inorganic salts, trace elements, etc. are all different. There are certain differences. The combination of a small number of strains cannot well adapt to the differences in raw materials in actual production, and cannot exert stable fermentation capacity for variable batches of raw materials. The use of such microbial agents with insufficient microbial compounding ability leads to fermentation. The quality of organic fertilizers is unstable, and even the final need to add chemical fertilizer raw materials to meet the specified quality standards, completely deviated from the original intention of organic fertilizers, it is difficult to adapt to the needs of large-scale commercial production, and it is even more difficult to predict that it can be stably promoted and applied to other industries. Soil conditioner; if it is necessary to control the quality of raw materials based on the fermentation ability of these small amount of bacterial strains, it is necessary to set up inspection procedures from the source of purchase from farmers, according to the required cost, human resources and small batch inspection capabilities , which is simply not feasible in reality
