Abstract

The invention discloses a compound microbial fertilizer. The compound microbial fertilizer is obtained by fully mixing 30-50 mass parts of straw, 20-40 mass parts of chicken manure, and 20-30 mass parts of a mixed bacterial solution, and performing composting fermentation. The mixed bacterial solution is formed by mixing of a mixed inoculant, an EM inoculant and a nutrient solution according to a mass ratio of 2:1:7, and the mixed inoculant is formed by mixing of, by mass, 20% of bacillus amyloliquefaciens, 15% of Streptomyces griseorubens, 5% of trichoderma atroviride, 25% of bacillus subtilis, 10% of azotobacter chroococcum, 10% of aspergillus, 10% of bacillus circulans and 5% of pseudomonas. Through screening of appropriate strain and nutrient solution, the compound microbial fertilizer can effectively improve soil quality and provide nutrients necessary for plants safely and environmentally friendly.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound microbial fertilizer. Background technique [0002] The extensive use of chemical fertilizers has greatly promoted the development of agriculture, but it has also brought many problems, such as environmental pollution and soil problems. Compound microbial fertilizer is a very good substitute for chemical fertilizers. It can not only efficiently provide the necessary elements such as nitrogen, phosphorus and potassium required by plants, but also avoid environmental pollution problems. Compound microbial fertilizer refers to living microbial products that are composed of specific microorganisms and nutrients, which can provide, maintain or improve plant nutrition, increase the yield of agricultural products or improve the quality of agricultural products. The microbial strains used should be safe and effective, but the strains currently used in many compound microbial fertilizers cannot...
