DETAILED DESCRIPTION - A composite microbial fertilizer comprises 8-12 wt.% potassium chloride, 0.2-1.0 wt.% manganese sulfate, 1-3 wt.% zinc sulfate, 20-25 wt.% peat, 5-15 wt.% chicken manure, 4-6 wt.% chicken slaughterhouse waste, 16-18 wt.% flax, 10-12 wt.% monosodium glutamate residue, 18-20 wt.% bean powder, 0.3-0.5 wt.% Bacillus amyloliquefaciens, 0.2-0.4 wt.% Bacillus subtilis, 0.4-0.6 wt.% jelly-like Bacillus, 0.8-1 wt.% Bacillus stearothermophilus, 0.2-0.4 wt.% L-lactic acid, 0.9-1.1 wt.% Aspergillus oryzae, 0.5-0.7 wt.% hemicellulase and 1.2-1.4 wt.% straw fermentation agent. An INDEPENDENT CLAIM is also included for a method for preparing composite microbial fertilizer, which involves inoculating Bacillus amyloliquefaciens and Bacillus subtilis in PDA slant medium to prepare a bacterial suspension, where the pH is 6-8, the cultivation temperature is 25-35 degrees C, incubation time is 15-17 hours, 1% pro rata of prepared bacterial inoculum suspension is inoculated in PDA liquid medium, followed by shaking, where the temperature is 28-32 degrees , inoculation time is 50-70 hours, inoculating Bacillus stearothermophilus and L-lactic acid in modified Camp-BAP medium, where the pH of the medium is 6-8, the starting temperature is 15-20 degrees C, culturing time is 16-18 days, inoculating 1.5% inoculum concentration into the modified Camp-BAP fermentation broth at 25-30 degrees C for 80-90 hours, drying flax by spread out to a moisture content below 10%, followed by cutting in a straw cutting machine to a length of 2-3 cm, performing fermentation by mixing Bacillus amyloliquefaciens, Bacillus subtilis, jelly-like Bacillus, hemicellulase and straw fermentation agent, followed by adding water, adding peat, flax, monosodium glutamate residue, bean powder, covering with plastic film, where the maturity period is 2-3 days, adding Bacillus stearothermophilus, L- lactic acid, Bacillus stearothermophilus to chicken manure and chicken slaughterhouse waste, followed by increasing oxygen content, cultivating for 1-2 days, covering the mixture with plastic film, where the maturity period is 3-4 days, preparing a mixture by mixing potassium chloride, manganese sulfate and zinc sulfate, followed by mixing with fermentation mixture, stirring, drying in a fluidized bed at 80 degrees C, where the moisture is controlled to be 10-15%, followed by crushing, sieving to 60 mesh, cooling and canning.
