NOVELTY - An antagonistic bacterium for removing drooping disease of continuous cropping cucumber with preservation number CGMCC NO. 3181, is new.    USE - The antagonistic bacterium is useful for removing drooping disease of continuous cropping cucumber and producing microbial organic fertilizer (all claimed).    ADVANTAGE - The microbial organic fertilizer is capable of making the antagonistic bacterium propagate quickly after being fertilized into the soil. The biological control rate for the drooping disease is greater than 70%. The drooping disease of the continuous cropping crop is avoided greatly by sterilizing the microbial organic fertilizer to the soil not formed with the continuous cropping obstruction for a long time.    DETAILED DESCRIPTION - An antagonistic bacterium for removing drooping disease of continuous cropping cucumber, the bacterial strain NJN 43 belongs to the Bacillus subtilis stored at the ordinary microbe center of the microbe culture preservation management committee of China in July 9, 2009, the preservation number of the strain is CGMCC NO. 3181, the main biological property is gram-positive, bacilliform cell, mesic spore, facultative anaerobic grow, positive catalase, positive V.P. reaction, positive methyl red test, fermenting glucose, xylose, L-pectinose and mannitol acid, citrate using, positive nitrate reductase, positive starch hydrolyzation, positive gelatine hydrolyzation and positive decomposing casein, is new. INDEPENDENT CLAIMS are:    (1) a microbial organic fertilizer generated by antagonistic bacterium for removing drooping disease of continuous cropping cucumber; and    (2) a production method for microbial organic fertilizer comprising: (a) inoculating the antagonistic bacterium NJN 43 to the potato dextrose agar (PDA) nutrient solution, performing the liquid fermentation production, the fermentation production condition is as follows: the grow range of the pH is natural, the culture temperature is 30 degrees C, the stirring speed is 180 to 300 rpm, the spore is formed at the middle and final period of fermentation, the bacterium or spore amount of the antagonistic bacterium in the fermenting liquid is greater than or equal to 1asterisk100000000000/ml; (b) performing the solid fermentation for the fermenting liquid of the antagonistic bacterium NJN 43 and the ripe pig manure compost and the rapeseed meal microbial enzyme mixture, adding 40 L NJN 43 fermenting liquid to one ton of solid organic material, turning one time in one day in the solid fermenting process, making the solid fermenting temperature less than or equal to 50 degrees C, ending after fermenting for 5 days, making the content of the antagonistic bacterium NJN 43 greater than 1asterisk1000000000/g, obtaining the microbial organic fertilizer of the pig manure compost and the microbial organic fertilizer of the rapeseed meal enzyme mixture; and (c) mixing the microbial organic fertilizer of the pig manure compost and the microbial organic fertilizer of the rapeseed meal enzyme mixture completely according to the volume ratio 60:40, ripening for 2 days, turning for 2 times in the post-ripening process, drying the post-ripe substance at low temperature till the water content is 30%, packaging, delivering and obtaining the microbial organic fertilizer for removing the drooping disease of continuous cropping cucumber.
