The invention relates to the technical field of microbial
fermentation, and discloses an agricultural ecological
probiotic complex
microbial inoculant, which is prepared from the following components in percentage by
mass: 30 to 35 weight percent of beneficial
microbial inoculant, 20 to 25 weight percent of mineral source
potassium fulvate, 15 to 20 weight percent of slow
release agent, 10 to 15 weight percent of nano polypeptide
fermentation liquor and the balance of carrier, the
processing method comprises the following steps: S1, pretreating the raw materials; s2, preparing nano polypeptide
fermentation liquor; s3, complex microbial inoculants are compounded; and S4,
drying and forming. According to the invention, the mineral source
potassium fulvic acid and the nano-polypeptide fermentation liquor are added, so that effective regulation and control of soil micro-
ecology are realized;
crop growth is promoted through cooperation of multiple strains,
growth hormone is secreted through
bacillus subtilis and the like,
nitrogen is fixed through
bacillus amyloliquefaciens, root development is stimulated in cooperation with mineral source
potassium fulvic acid, and the
plant height, stem
diameter and
fresh weight of crops are remarkably increased; the particle size of the polypeptide subjected to high-pressure homogenization treatment is 80-120nm, the
absorption efficiency is improved by 60%, and a
crop disease-resistant
signal channel is activated.
