Organic fertilizer fermentation microbial agent and preparation process

Abstract

The invention belongs to the technical field of organic fertilizer fermentation, and discloses an organic fertilizer fermentation microbial agent and a preparation process. The preparation process is characterized by comprising the following steps of: S1, performing test tube culture; S2, performing shake-flask culture; S3, performing seeding tank culture: performing continuous aerobic culture on a culture solution I, a culture solution II and a culture solution III in a culture medium I, a culture medium II and a culture medium III respectively under the conditions that the inoculation amount is 0.5-1 percent and the temperature is 28-32 DEG C for 48 hours, and transferring into a fermentation tank for performing enlarged culture when proper conditions are met; S4, preparing a microbial carrier; and S5, drying the microbial carrier: smashing the microbial carrier through a sterile smashing machine to obtain a 120-mesh organic fertilizer fermentation microbial agent. The organic fertilizer fermentation microbial agent is cultured in a multi-step and classified way, so that the microbial growth index of various strains can be increased greatly, and the activity of each strain is increased greatly. When the fermentation microbial agent is used for preparing an organic fertilizer, nitrogen fixation, phosphorus dissolution, potassium dissolution, activation and decomposition of organic matters are realized, and escherichia coli and ascaris eggs are killed.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer fermentation, in particular to an organic fertilizer fermentation bacterial agent and a preparation process. Background technique [0002] The organic fertilizer starter can decompose protein, cellulose, hemicellulose, lignin, etc., and compound bacteria and fungi. The organic fertilizer starter produced and developed by Beijing Huiminda Science and Technology Development Center has a high content of effective viable bacteria. It has strong degradation ability, and can achieve the effects of heating up, deodorizing, eliminating pests, weed seeds and improving nutrients at the same time. Under suitable conditions, it can quickly decompose and mineralize carbon, nitrogen, phosphorus, potassium, sulfur, etc. in the pile to form simple organic matter, which is further decomposed into nutrients that can be absorbed by crops. [0003] The Chinese invention patent with the application publica...

Problems solved by technology

[0003] The Chinese invention patent with application publication number CN112662593A discloses an organic fertilizer fermenting bacteria agent, which provides a method that can accelerate the fermentation and decomposing speed of organic waste, reduce the number of turning times, and shorten the time of fermentation and decomposing, but the microorganisms in this invention The fermentation method is not suitable for different types of bacterial agents. The organic microbial agent prepared by this method has low microbial activity, which leads to poor activation rate and various physical and chemical properties of subsequent organic fertilizers. The activity of the bacteria species decreases, and the number of bacteria increases slowly or Individual strains cannot survive, greatly reducing production efficiency
