NOVELTY - Microbial organic fertilizer is obtained by preparing bacteria seed solution through liquid fermentation cultivation, drying water hyacinth, crushing water hyacinth, grass peat, humic acid and powdered rock phosphate, mixing and fermenting crushed water hyacinth residue, grass peat, humic acid and powdered rock phosphate to obtain biological fertilizer matrix, and uniformly mixing the bacteria seed solution and biological fertilizer matrix to obtain microbial organic phosphate fertilizer.    USE - The microbial organic fertilizer is useful for preventing and controlling pseudoginseng blight (claimed).    ADVANTAGE - The fertilizer is cost-effective, convenient to use, nontoxic, and environmentally-friendly, can thoroughly sterilize harmful germs in pseudoginseng soil, supplements nutrient elements required by growth of pseudoginseng plants, and improves physical and chemical properties and microbial activity of soil with continuous cropping obstacles and stress resistance of the pseudoginseng plants.    DETAILED DESCRIPTION - Microbial organic fertilizer is obtained by (a) (i) transplanting KMXY1 strain (CGMCC NO: 6598) to test tube comprising Lysogeny broth (LB) culture medium, culturing medium at 29 degrees C for 48 hours, where the LB culture medium comprises 10 g/L tryptone, 5 g/L yeast extract, 5 g/L sodium chloride and 17 g/L agar (pH 7), (ii) obtaining bacterial lawn and adding LB culture medium comprising 10 g/L tryptone, 5 g/L yeast extract and 5 g/L sodium chloride into 1000 ml bottle, fermenting medium at 110 revolutions per minute (rpm) and 29 degrees C for 72 hours to obtain fermentation broth, (iii) inoculating fermentation broth in LB culture medium in seed tank in a ratio of 1:200, fermenting the medium at 29-31 degrees C for 16-18 hours to obtain fermented bacteria, and (iv) inoculating strain to LB medium in a ratio of 1:20, fermenting medium at 29-31 degrees C for 72-96 hours to bacteria seed solution, (b) (i) drying water hyacinth, crushing water hyacinth into fineness of less than or equal to 5 cm, crushing peat to less than or equal to 0.45 mm, crushing humic acid to less than or equal to 0.45 mm and crushing phosphate rock to less than or equal to 400 meshes sieve, and (ii) mixing and fermenting crushed water hyacinth residue, grass peat, humic acid and powdered rock phosphate in a ratio of 5:3:1:1 to obtain biological fertilizer matrix, and (c) uniformly mixing the bacteria seed solution and biological fertilizer matrix to obtain microbial organic phosphate fertilizer, where the fertilizer comprises 1x 1011/g antagonistic microbes, 5-6% nitrogen, 6-8% nitrogen phosphorus and potassium and 40% organic matters.
