NOVELTY - An antagonistic bacteria strain NJN-6 of preservation number CGMCC NO. 3183 and strain NJN-11 of preservation number CGMCC NO. 3184, for preventing and treating Panama wilt disease of continuously planted banana, is new.    USE - The antagonistic bacteria strains NJN-6 and NJN-11 are useful for preventing and treating Panama wilt disease of continuously planted banana and producing the microorganism organic fertilizer (all claimed).    ADVANTAGE - The antagonistic bacteria can reach greater than 80% of rate on preventing and treating the Panama wilt disease, and it can control the Panama wilt disease of the banana to be lower than 5% on the land of serious disease (the disease ratio of the current season is greater than 15%); the product, as long as it is continuously applied, can effectively control the wilt disease.    DETAILED DESCRIPTION - An antagonistic bacteria for preventing and treating Panama wilt disease of continuously planted banana, where the antagonistic bacteria include strain NJN-6 and strain NJN-11 which are Bacillus subtilis; the strains are preserved in General Microorganism Center of China Committee for Culture Collection of Microorganism in July 9, 2009; the preservation number of the NJN-6 strain is CGMCC NO. 3183, and that of the NJN-11 is CGMCC NO. 3184; the major biological characters of the NJN-6 strain include the follows: gram-positive, the cell is represented as rod that is bred with spores at end; the strain is of facultative anaerobic growth; the catalase is positive and the oxidase is negative; the V.P. reaction is positive, and the methyl red test is negative; the process of fermenting glucose generates acid but not generates gas, and the process of fermenting fructose generates both acid and gas; the xylose, the L-arabinose and the mannitol are not fermented; it can use citrate; nitrate reductase is positive, the amylohydrolysis is positive, the gelatin hydrolysate is positive, and the decompressed casein is positive; the major biological characters of the NJN-11 strain include the follows: gram-positive G+, the cell is represented as rod that is bred with spores at end; the strain is of facultative anaerobic growth; the catalase is positive and the oxidase is negative; the V.P. reaction is positive, and the methyl red test is positive; both processes of fermenting glucose and fructose generate acid but not generate gas; the xylose, the L-arabinose and the mannitol are not fermented; it can use citrate; nitrate reductase is positive, the amylohydrolysis is positive, the gelatin hydrolysate is positive, and the decompressed casein is positive, is new. INDEPENDENT CLAIMS are:    (1) a microorganism organic fertilizer produced by the antagonistic bacteria for preventing and treating Panama wilt disease of continuously planted banana comprising more than 1x108 pieces/g of NJN-6 and NJN-11 strains; mass ratio of total nitrogen content is 4-5%; in the total nitrogen, mass ratio of the organic nitrogen is greater than 90%; mass ratio of the total-nitrogen phosphorus potassium is 6-10%; and mass ratio of the organic material is 30-35%; and    (2) a method for producing the microorganism organic fertilizer comprising: (a) inoculating the antagonistic bacteria NJN-6 and NJN-11 into the potato dextrose agar (PDA) culture medium; producing the antagonistic bacteria by liquid fermentation until the number of bacteria or spores in the fermenting liquid is not lower than 1x1010 pieces/ml under the following conditions: pH value is at 6.0-7.0, the fermentation temperature is at 30-35 degrees C, the stirring speed is at 180-300 rpm, and the fermenting duration is 48 hours; (b) inoculating the NJN-6 and NJN-11 fermenting liquid into the rotten pig manure compost and microorganism decompressed mixture of the vegetable bran by amount of 50 L/ton, and performing solid fermentation to the NJN-6 and NJN-11 fermenting liquid; during fermenting, turning the stack once every day; fermenting the NJN-6 and NJN-11 fermenting liquid for 5 days at a temperature not greater than 50 degrees C until the contents of both antagonistic bacteria NJN-6 and NJN-11 are greater than 1 to the power of 8 pieces/g to obtain rotten pig manure compost solid bacterium of antagonistic bacterium NJN-6 , microorganism decompressed mixture solid bacterium of vegetable bran and two solid bacteria of the NJN-11; (c) by the rotten pig manure compost and the microorganism decompressed mixture solid bacterium of vegetable bran, mixing the antagonistic bacterium NJN-6 solid bacterium and the NJN-11 solid bacterium at ratio of 1:1 by volume to obtain solid mixing bacterium of the rotten pig manure compost and solid mixing bacterium of the microorganism decompressed mixture solid bacterium of vegetable bran; and (d) completely mixing the solid mixing bacterium of the rotten pig manure compost and solid mixing bacterium of the microorganism decompressed mixture solid bacterium of vegetable bran at ratio of 50-70%: 30-50% by volume; after-ripening the mixture for 2-3 days; meanwhile, turning the stack for twice; evaporating the microorganism organic fertilizer at a temperature not greater than 60 degrees C until the water content is lower than 30%; packaging the microorganism organic fertilizer; and discharging the microorganism organic fertilizer out of the factory to obtain the needed microorganism organic fertilizer capable of preventing and treating Panama wilt disease of continuously planted banana.
