Abstract

The invention discloses a preparation method of composite microbial fertilizer and prepared composite microbial fertilizer. The preparation method comprises a yeast pre-fermentation step, a compositestrain fermentation step and a post-fermentation treatment step. In the invention, a straw composition is creatively pre-fermented with yeast, and metabolite contained in a fermentation product is suitable for fermentation of a composite flora. The composite microbial fertilizer has wide raw material sources, mild fermentation conditions and strong vigorous species, and after long-term use, the soil micro-ecological environment can be significantly improved, the soil fertility is improved, and the purposes of increasing crop yield and increasing efficiency are achieved.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a method for preparing a compound microbial fertilizer and the prepared compound microbial fertilizer. Background technique [0002] Agriculture is the basic industry of our country. The planting and cultivation of crops in modern agriculture requires a variety of nutrients. The long-term use of traditional industrial fertilizers will lead to dry soil, decline in soil fertility, damage to soil structure, microbial flora and diversity, resulting in a serious decline in agricultural production. Organic fertilizers can avoid the disadvantages of traditional industrial fertilizers, but organic fertilizers are limited to sources, and the yield is low, which obviously cannot meet the needs of plants. [0003] Among the new fertilizers, microbial fertilizers are also called bacterial agents or bacterial fertilizers, which are mainly composed of beneficial microorganisms, organi...
