NOVELTY - An antagonist bacteria for preventing and killing off tomato bacterial wilt of continuous cropping, where the antagonist bacteria NJQL-18 belongs to the Bacillus amyloliquefaciens with preservation number is CGMCC NO. 3177, is new.    USE - The antagonist bacteria is useful for preventing and killing off tomato bacterial wilt of continuous cropping and generating micro-organism organic fertilizer (all claimed).    ADVANTAGE - The antagonist bacteria are quickly propagated for forming an advantageous group in the soil after fertilizing the micro-organism organic fertilizer; the prevention efficiency of the serious tomato bacterial wilt in the soil reaches 80%. The micro-organism organic fertilizer is chronically fertilized in the soil without the continuous cropping obstacle for greatly preventing the tomato bacterial wilt of continuous cropping.    DETAILED DESCRIPTION - An antagonist bacteria for preventing and killing off tomato bacterial wilt of continuous cropping, where the antagonist bacteria NJQL-18 belongs to the Bacillus amyloliquefaciens, which is stored in the common micro-organisms center of China Committee for Culture Collection of Microorganism in July 9, 2009, the strain preservation number is CGMCC NO. 3177, the main biological characteristics is Gram-positive; the cell shape is a short pole shape for forming a spore; the cell is grown up by facultative anaerobe; the catalase action is positive; the litmus milk is used for generating acids and peptonizing; the V.P. action is positive; the methyl red test is negative; glucose, milk sugar, mannitol, sorbose, cellobiose, rhamnose, galactose, fructose, maltose, cane sugar, pectin sugar and xylose are fermented for generating acids and gases without citrate; the nitrate reductase is positive, the amylolysis is positive, and the gelatin hydrolysate is positive and the decomposition casein is positive, is new. INDEPENDENT CLAIMS are:    (1) a micro-organism organic fertilizer for preventing tomato bacterial wilt of continuous cropping tomatoes, which is generated by the antagonist bacteria NJQL-18; and    (2) a method for generating micro-organism organic fertilizer for preventing tomato bacterial wilt of continuous cropping tomatoes comprising: (a) the antagonist bacteria NJQL-18 is inoculated to the potato dextrose agar (PDA) nutrient solution for fermenting and generating liquid; the fermentation condition is the as follows: the PH generating range is natural, the cultivation temperature range is 25-30 degrees C, the mixing speed is 180-300 rotations/minute, the spore is formed in the back period when fermenting, each milliliter of the bacteria quality or the spore quality of the fermented antagonist bacteria is not less than 1x1010; (b) the antagonist bacteria is fermented with pig manure composting and vegetable dregs micro-organism enzymolysis mixture, each ton solid organic material is added with 50 L antagonist bacteria liquid, the fermenting temperature is 30-50 degrees C for making each gram of the antagonist bacteria content attain more than 1x108 and obtaining the solid microbial inoculums of the antagonist bacteria NJQL-18; and (c) the solid microbial inoculums of the antagonist bacteria NJQL-18 of the pig manure composting is fully mixed with the solid microbial inoculums of the antagonist bacteria NJQL-18 of vegetable dregs micro-organism enzymolysis mixture by the volume ratio in accordance with 50-70% to 30-50%, which are turned for two times in the after-ripening process for 2-3 days; the water content of the micro-organism organic fertilizer is evaporated lower than 30% in the condition of not exceeding 60 degrees C, which is packaged as the micro-organism organic fertilizer for preventing tomato bacterial wilt of continuous cropping.
