NOVELTY - Method for producing growth-promoting bio-organic fertilizer involves inoculating rhizosphere growth-promoting Bacillus amyloliquefaciens strain SQR9 (CGMCC NO: 5808) into potato dextrose agar (PDA) culture medium, sterilizing, and uniformly mixing algae mud, waste feather extruded powder, rapeseed meal and cattle manure, inoculating fermenting liquor into solid fermentation, mixing mineral ore particles in solid organic material and fermenting and packing the finished product.    USE - The method is useful for producing growth-promoting bio-organic fertilizer, which is useful in promoting growth of plants (all claimed), food crops and vegetables.    ADVANTAGE - The fertilizer is rich in beneficial amino acid, has low production cost and can be applied to food crops and vegetables.    DETAILED DESCRIPTION - Method for producing growth-promoting bio-organic fertilizer involves (a) inoculating rhizosphere growth-promoting Bacillus amyloliquefaciens strain SQR9 (CGMCC NO: 5808) into potato dextrose agar (PDA) culture medium, and carrying out liquid fermentation at the temperature of 30-35 degrees C, and speed of 180-300 revolution per minute, where the amount of bacteria or the spore in the fermentation liquid is more than 1 x 109 /ml, and the PDA culture medium is prepared by boiling 200 g potatos (which are peeled and cut into small pieces) for 30 minutes, filtering the product, adding 20 g ordinary sugar to product, and setting volume of product to 1000 ml and pH to 7-7.6, sterilizing the product at 121 degrees C for 20 minutes, and uniformly mixing 5% algae mud, 10% waste feather extruded powder, 10% rapeseed meal and 75 cattle manure, (c) inoculating growth-promoting bacteria SQR9 fermenting liquor into the solid fermentation medium, mixing mineral ore particles in solid fermentation medium to obtain 50 l growth medium, turning the solid fermentation process once a day at the temperature not greater than 50 degrees C, for 6-7, maintaining the product, until bacterial growth reaches more than 2x 108 colony-forming units (CFU)/g fertilizer, where the water content of the organic fertilizer is less than 30%, packing the finished bio-organic fertilizer having fertilizer germination index of more than 98%, organic matter content of less than 45%, organic nitrogen content of 2-3%, and moisture content of 25-30%.
