Composite microbe fertilizer and preparation method thereof

Abstract

The invention relates to a composite microbe fertilizer. The composite microbe fertilizer is prepared by 25-35 wt% of vegetable garden soil, 5-10 wt% of active functional bacteria, 5-15 wt% of mineral powder, 25-30 wt% of an organic fertilizer, 15-20 wt% of an inorganic composite fertilizer, and water; wherein the sum of the components is 100%. The active functional bacteria comprise lactic acid bacteria, bacillus subtilis, Bacillus megaterium, trichoderma, aspergillus niger, monascus, Trichoderma harzianum, aspergillus aculeatus and yeast, the mineral powder is a mixture of one or more of peat, zeolite, vermiculite, montmorillonite, calcium carbonate and expanded perlite, fineness of the mineral powder is less than or equal to 200 meshes, the organic fertilizer contains decomposed manure, a rapeseed cake fertilizer, and straw, and the weight ratio of the manure to the rapeseed cake fertilizer to straw is 5.5-7.5:2.5-3.5:0.5-1.5.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a compound microbial fertilizer and a preparation method thereof. Background technique [0002] The compound microbial fertilizer has comprehensive nutrients and can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the compound microbial fertilizer enter the soil and form a mutual symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role in the group. The beneficial bacteria grow and reproduce A large number of metabolites are produced during the process, which promotes the decomposition and transformation of organic m...

AI Technical Summary

Problems solved by technology

Since the compound microbial fertilizer contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic raw materials, it is more difficult to dissolve after granulation, and the granulation affects the quality of the product. and effects

However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products
