NOVELTY - A spinach Chinese medicine microbial fertilizer preparation method involves culturing microorganism by inoculating Bacillus amyloliquefaciens. A crop straw treatment is performed by drying and crushing corn straw and soybean straw. The crushed straw is mixed with pig manure and chicken manure. Fermenting process is performed by placing the obtained mixture in a fermentation tank, and adding the microorganism. Drying and crushing process is performed by drying the obtained mixed material in a fluidized bed, crushing and sieving the mixed material to obtain a finished product.    USE - Method for preparing a Chinese medicine microbial fertilizer that is utilized for spinach cultivation.    ADVANTAGE - The method enables preparing the Chinese medicine microbial fertilizer with economic and social benefits.    DETAILED DESCRIPTION - A spinach Chinese medicine microbial fertilizer preparation method involves culturing microorganism by inoculating Bacillus amyloliquefaciens, Bacillus thuringiensis, Bacillus subtilis to a PDA inclined surface culture medium at 20-40 degrees C for 12-20 hours to obtain a bacterial suspension, inoculating the bacterial suspension to a PDA liquid culture medium, and shaking the liquid culture medium at 25-30 degrees C for 48-72 hours to obtain microorganism. A crop straw treatment is performed by drying corn straw, cotton straw and soybean straw until water content reaches less than 10%, and cutting and crushing the straws by a straw cutting machine to obtain a crushed material. The crushed straw is added and mixed with pig manure, chicken manure, pork slaughterhouse waste and chicken slaughterhouse waste at a weight ratio of 2:3:1:1 to obtain a mixture. Fermenting process is performed by placing the mixture in a fermentation tank, adding the microorganism, brown sugar and water, where weight ratio of the mixture, water, the microorganism and the brown sugar is 1000-1200:200-400:1:2, culturing the obtained mixed material for 1-2 days, and covering the mixture by a plastic film for 2-3 days at 65 degrees C to obtain a fermented product. Calcium super-phosphate, boric sludge, potassium fulvate, water, Japanese Artemisia rupestris, Semen momordicae, Stellera chamaejasme, hop, Radix sophorae flavescentis and golden larch bark are mixed and stirred according to weight ratio of 2:1:3:4:3:4:4:2:1:3 to obtain a mixed material. The mixed material is mixed with the fermented product, mixing them uniformly according to a weight ratio of 80-100:1. Drying and crushing process is performed by drying the mixed material in a fluidized bed at 80 degrees C, crushing and sieving the mixed material, conveying the crushed mixture to a drum granulator by a transmission belt, spraying steam in the granulator for heating mixture at 50-60 degrees C, continuously rotating the roller to make the material into a ball, and conveying the ball to a drying roller, cooling the ball, and sieving and packing the ball to obtain a finished product.
