Biological water-soluble fertilizer containing amino acid and fulvic acid and preparation method thereof

The invention discloses a biological organic water-soluble fertilizer containing amino acid and fulvic acid and a preparation method thereof, the biological organic water-soluble fertilizer is prepared by adding a zymophyte solution into peanut bran for fermentation, and the zymophyte solution is prepared by mixed fermentation of a complex microbial inoculant, molasses and water. The complex microbial inoculant comprises phanerochaete chrysosporium, aspergillus niger, bacillus, saccharomycetes, lactic acid bacteria and photosynthetic bacteria. Peanut bran is used as a main raw material, and the biological organic water-soluble fertilizer obtained by fermentation of a complex microbial inoculant is rich in amino acid and fulvic acid. The method solves the problems of long time consumption of peanut bran accumulation and decomposition, stink and long peanut bran fertilizer absorption time of plants, the prepared water-soluble fertilizer can improve soil organic matters and restore the soil micro-ecological envi
