NOVELTY - Production of biological organic fertilizer includes: inoculating strain preservation number CGMCC NO. 3183 promoting bacteria NJN-6 to potato dextrose agar (PDA) culture medium, carrying out liquid fermentation production; taking chicken manure, vegetable microbe enzymolysis mixture and feather swelling powder at a mass ratio of 8:1:1 to form solid organic material for solid fermentation; inoculating into solid organic material, carrying out solid fermentation and evaporating water.    USE - Biological organic fertilizer used for promoting growth and preventing wilt of bananas (claimed).    ADVANTAGE - The product beneficial viable bacteria is not greater than 1x 109 CFU/g, dry weight of fertilizer total nitrogen content mass ratio is 3-4%, total nitrogen-phosphorus-potassium nutrient mass ratio is 6-8%, and mass ratio of organic matter content is greater than or equal to 45%.    DETAILED DESCRIPTION - Production of biological organic fertilizer comprises: (A) inoculating strain promoting bacteria NJN-6 (CGMCC 3183) to PDA culture medium, carrying out liquid fermentation production, fermentation production pH is 6.0-7.5, fermentation temperature is 30-35 degrees C, stirring speed is 180-300 revolutions per minute, forming spores, fermentation time is 48 hours, to obtain generating bacteria NJN-6, fermentation liquid containing bacteria or spore amount is greater than or equal to 1x 1010 units per ml; preparing 1 L PDA culture medium comprises: taking 200 g potato peeling, cutting pieces, placing into boiling water, boiling for 30 minutes, filtering liquid, adding 20 g common sucrose, filtering at constant volume to 1000 ml, adjusting pH value to 7.2-7.4, sterilizing at 121 degrees C for 20 minutes; (B) taking chicken manure, vegetable microbe enzymolysis mixture and feather swelling powder at a mass ratio of 8:1:1 to form solid organic material for solid fermentation; preparing vegetable microorganism enzymolysis mixture by adding Stenotrophomonas maltophilia strain 37-1 (CGMCC 1543) fermentation liquor into vegetables, adjusting water content to 55-65% and pH is 6.0-7.5, carrying out solid fermentation, raising fermentation temperature to 50 degrees C, turning every day, always keeping temperature at 35-50 degrees C for 5 days, after solid fermentation, pH continuously increasing, regulating water content and pH to 55-65% and 6.0-7.0 respectively, spraying with liquid, adjusting pH to 5.0, then carrying out low temperature drying or natural drying, to obtain vegetable microbial enzymolysis mixture; chicken manure for composting germination index is 98% or more, mass ratio of organic matter content is greater than or equal to 45%, organic nitrogen mass content is 2-3%, and water content is 25-30%; and (C) inoculating NJN-6 ferment liquid into vegetables microorganism enzymolysis mixture, chicken manure fertilizer and feather swelling powder for solid fermentation, adding per ton of solid organic material into 50 L bacteria liquid, turning once a day, maintaining solid fermentation temperature not more than 50 degrees C, fermenting for 5-7 days, generating promoting bacteria content can reach more than 1x 109 CFU/g, evaporating water of microbial organic fertilizer at temperature not more than 60 degrees C, to water content below 30%, packaging factory to obtain banana special biological organic fertilizer.
