Preparation method for microbial soil improvement solution

Abstract

The invention discloses a preparation method for a microbial soil improvement solution. The microbial soil improvement solution comprises ultrafine plant powder, water and a beneficial microbial strain. The preparation method is characterized by comprising the following steps: step 1, material preparation; step 2, heating and saccharification; step 3, addition of the beneficial microbial strain; step 4, pressurization and splitting; step 5, homogenization and fermentation; and step 6, filtering and canning. According to the invention, high-protein plant materials like soybean are subjected to cell wall-breaking ultrafine crushing; a logarithmic propagation high-oxygen-environment fermentation method is employed, so fermentation time is short, and a saturation concentration of probiotics can be reached; cell wall-breaking ultrafine crushing enables nutritional components in raw materials to be fully dissolved and totally destroys the cell walls of eggs and harmful bacteria and spores thereof; a probiotic group is high in purity and free of harmful floras; so the microbial soil improvement solution really improves soil and overcome disadvantages in the prior art.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for preparing microbial soil improvement liquid. Background technique [0002] The organic fertilizers in the prior art mainly use human and animal feces as the main raw materials. After a short-term high-temperature treatment, probiotics are added for stacking and fermentation. Due to the large amount of raw material processing, the short-term high temperature cannot effectively kill the deep parasites and eggs inside the raw materials. And harmful bacteria, the content of probiotics produced by stacking and fermentation is low, and it needs to be dried to further reduce the content and activity of probiotics. High temperature treatment and drying process will emit harmful gases and pollute the environment. [0003] The present invention selects high-protein plant raw materials such as soybeans for superfine pulverization of broken cell walls, and adopts a l...
