A composite microbial strain for aerobic fermentation stage

Abstract

The invention provides a compound microbial bacterium for an aerobic fermentation stage. The compound microbial bacterium for an aerobic fermentation stage is prepared by culturing, fermenting, drying and mixing Bacillus licheniformis, Bacillus subtilis, saccharomycete, 5406 actinomycete, Trichoderma viride, Aspergillus oryzae and pseudomonad respectively, wherein the compound microbial bacterium comprises the following components in parts by weight: 0.7-1.2 parts of Bacillus licheniformis, 0.7-0.8 part of Bacillus subtilis, 1.1-1.2 parts of saccharomycete, 1.5-2.5 parts of 5406 actinomycete, 1-2 parts of Trichoderma viride, 1-2 parts of Aspergillus oryzae and 0.5-1 part of pseudomonad. The compound microbial bacterium for an aerobic fermentation stage has phosphate-solubilizing, potassium-solubilizing and nitrogen-fixing capabilities, and can quickly decompose organic substances, so that materials are thoroughly decomposed, and oxidation-resistant substances are generated through metabolism, thus generating a complex and stable ecological system; and the heating speed is high in the whole fermentation process, the temperature can be up to 50 DEG C or above within 1-2 days, and undesirable odor starts to disappear within 24 hours.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, in particular to a composite microbial bacterium used in the aerobic fermentation stage. Background technique [0002] The survival of plants depends on the soil, and fertilizer is the food of plants. Plants need a lot of nutrients to promote their rapid growth during the growth process. Different soils have certain effects on the growth of crops, which requires effective soil improvement. Most of the soil is replaced by the use of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest, especially saline-alkali land occupies a large area of ​​land in our country and even in the world. Alkaline emphasis on two parts can be cultivated, resulting in a lot of investment in improvement, but the effect is very small. [0003] Bio-organic fertilizer is rich in various nutrients needed by crops and rich in ben...
