DETAILED DESCRIPTION - An insecticidal sterilizing microbial fertilizer comprises 8-12 pts. wt. potassium chloride, 0.2-1.0 pts. wt. manganese sulfate, 1-3 pts. wt. zinc sulfate, 20-25 pts. wt. grass carbon, 5-15 pts. wt. fowl manure, 4-6 pts. wt. chicken slaughter house waste, 16-18 pts. wt. stalks, 10-12 pts. wt. residue of monosodium glutamate, 18-20 pts. wt. soya bean meal powder, 0.3-0.5 pts. wt. Bacillus amyloliquefaciens, 0.2-0.4 pts. wt. Bacillus subtilis, 0.4-0.6 pts. wt. jelly-shaped Bacillus, 0.8-1 pts. wt. Bacillus stearothermophilus, 0.2-0.4 pts. wt. lactic acid Bacillus, 0.9-1.1 pts. wt. Aspergillus, 0.5-0.7 pts. wt. hemicellulase, 1.2-1.4 pts. wt. straw fermenting agent, 20-30 pts. wt. pepper, 20-30 pts. wt. Ginkgo, 20-30 pts. wt. common Cnidiumfruit, 10-30 pts. wt. cortex meliae, 15-25 pts. wt. quisqualis, 1-15 pts. wt. Chinese gall, 5-15 pts. wt. ilex pubescens, 5-10 pts. wt. radix Sophorae flavescentis and 55-60 pts. wt. soapberry peel. An INDEPENDENT CLAIM is also included for a method for preparing insecticidal sterilizing microbial fertilizer, which involves inoculating Bacillus amyloliquefaciens, Bacillus subtilis and Bacillus in a PDA culture medium at 25-35 degrees C for 15-17 hours to prepare bacteria suspension, inoculating the bacteria suspension in a PDA liquid culture medium at 28-32 degrees C for 50-70 hours, mixing Bacillus stearothermophilus and lactic acid bacillus with the bacteria suspension at 15-20 degrees C for 16-18 days, where the temperature is increased to 22-24 degrees C for 12-16 days, carrying out fermentation at 25-30 degrees C for 80-90 hours, spreading flax in the suspension when the water content is less than or equal to 10 wt.%, cutting the straw by a straw cutting machine with length of 2-3 cm, mixing de-starch bacillus licheniformis, Bacillus subtilis, bacillus mucilaginosus, hemicellulase, straw fermenting agent, water, grass peat, flax and monosodium glutamate dreg to obtain bean platinum powder mixture, carrying out fermenting process at greater than or equal to 60 degrees C with interval of 1-2 days for 8-10 days, adding and culturing bacillus stearothermophilus, lactic acid bacillus, Aspergillus, chicken manure and chicken slaughterhouse waste for 3-4 days with interval of 1-2 days at 50-55 degrees C until the water content is 35-40 wt.%, where the mixture is covered by covered by plastic film, mixing potassium chloride, manganese sulfate, zinc sulfate, Chinese prickly ash, Ginkgo skin, fructus cnidii, cortex meliae, quisqualis, gallnut, hairy holly root and radix Sophorae flavescentis with the resulted material to obtain mixed fertilizer, carrying out a fluidized bed drying process to dry the resulted mixture at 80 degrees C until water content is 10-15 wt.%, crushing, sieving and crushing the mixture, spraying steam on the mixture, subjecting the mixture in a roller, and heating the mixture in through the roller continuously rotate to make the mixture into ball, sending the ball to a drying roller to dry the ball with hot wind, followed by cooling, sieving and packing a finished product.
