NOVELTY - Microbial fertilizer, prepared by culturing Azotobacter chroococcum, filamentous thermophilic Bacillus, Bacillus natto intracellular enzymes, silicate bacteria, vesicular arbuscular (VA) mycorrhizae and phosphate bacteria, to obtain fermented cells, and sterilizing for 20 minutes-based on production culture conditions of a fermentation tank, and reducing culture medium temperature adding more bacterial strains, and fermenting under aerobic conditions, to obtain the product, where the effective number of viable cells is greater than or equal to 5x 109 (5000000000) cells/ml, is claimed.    USE - The microbial fertilizer is useful for fruit trees (claimed); and increasing plant disease resistance, and drought resistance capacity.    ADVANTAGE - The microbial fertilizer improves physical and chemical properties of soil; increases soil fertility; facilitates plant to absorb nutrients; is environmental friendly, and economical; and saves energy.    DETAILED DESCRIPTION - Microbial fertilizer, prepared by culturing Azotobacter chroococcum, filamentous thermophilic Bacillus, Bacillus natto intracellular enzymes, silicate bacteria, vesicular arbuscular (VA) mycorrhizae and phosphate bacteria, to obtain fermented cells, and sterilizing at 121 degrees C for 20 minutes-based on production culture conditions of a fermentation tank, and reducing culture medium temperature to 33 degrees C, adding more bacterial strains at 33 plus minus 2 degrees C, and fermenting for 24-30 hours under aerobic conditions, to obtain the product, where the effective number of viable cells is greater than or equal to 5x 109 (5000000000) cells/ml, is claimed. An INDEPENDENT CLAIM is also included for use method of microbial fertilizer for fruit trees, comprising taking culture medium includes 2-6% brown sugar, 5-15% mannitol, 1-2% zinc gluconate, 1-2% peptone, 2-4% beef extract, 1-3% sodium chloride, 0.15% potassium dihydrogen phosphate, 0.6% ammonium molybdate and 0.02% calcium carbonate and ferrous chloride, and then adjusting pH to 7.2-7.5, sterilizing, and fermenting to obtain microbial fertilizer stock solution, diluting for 300 times, and adding water into plant seeds during cultivation process, and carrying out field management process.
