NOVELTY - Microbial organic fertilizer comprises 15-20 mass% of Bacillus mucilaginosus CICC No. 21699, 15-18 mass% of Bacillus megaterium ACCC No. 11011, 15-18 mass% of Azotobacter chroococcum CICC No. 20025, 10-13 mass% of Saccharomyces cerevisiae ACCC No. 20034, 10-13 mass% of Candida utilis ATCC No. 22023, 10-13 mass% of Lactobacillus plantarum ATCC No. 8014, and 15-18 mass% of Dactylosporangium species ACCC No.40661 as producing strain.    USE - The microbial organic fertilizer is useful for promoting growth of crops.    ADVANTAGE - The microbial organic fertilizer has high stability, is convenient to use, improves the quality, yield, disease resistance and shape of fruit and the plant, and improves soil ecological environment.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing microbial organic fertilizer, comprising (1) preparing solid culture medium for each strain, carrying out sterilization and transferring from an inclined surface to a flat surface for culturing at a temperature of 30 degrees C for 2-3 days, (2) selecting single colony to set with a first level liquid culture medium of 50 ml conical flask for sterile operation at 30 degrees C and a speed of 130 revolutions per minute (rpm) for 24-48 hours, (3) cultivating the primary strain and then inoculating in second level liquid culture medium of 50 ml conical flask for sterile operation at 30 degrees C and a speed of 130 rpm for 24-48 hours, and (4) mixing each strain according to the mass percentage and then inoculating in fermentation liquid culture medium in a fermentation tank, and culturing 1-5% of inoculum at 30 degrees C for 4-7 days until bacterial fermentation broth concentration reaches to 10-15\108 cells/ml, where the fermentation liquid culture medium comprises 10-50 g/l of honey, 20-100 g/l of sucrose, 1-5 g/l of peptone, 1-5 g/l of potassium dihydrogen phosphate, 1-5 g/l of urea, 5-20 g/l of potassium monohydrogen phosphate (K2HPO4), 5-20 g/l of magnesium sulfate heptahydrate (MgSO4.7H2O), 5-20 g/l of sodium chloride (NaCl), 5-20 g/l of ammonium sulfate and balance amount of distilled water and has a pH of 6-8.
