NOVELTY - A composite bacteria biological fertilizer is prepared by adding e.g. Nocardia, Bacillus subtilis, Lactobacillus, Bacillus mucilaginosus, Bacillus megaterium, photosynthetic bacteria and alcohol yeast into stainless steel fermentation, and stirring; adding e.g. brown sugar, monopotassium phosphate, magnesium sulfate heptahydrate and urea, and fermenting while stirring to obtain mixture; drying fulvic acid, livestock manure, soybean meal, straw and fruit residue, crushing, and stirring; adding mixture, stirring, placing in bags and fermenting.    USE - Method for preparing composite bacteria biological fertilizer (claimed).    ADVANTAGE - The fertilizer solves the problems about time-consuming and labor-extensive aerobic fermentation process and loss of nutrients such as protein and fiber which causes production of heat and odor. The method is simple and safe, has wide raw material source and low cost, and does not pollute the environment.    DETAILED DESCRIPTION - A composite bacteria biological fertilizer is prepared by adding 3-7 pts. wt. Nocardia, 6-11 pts. wt. Bacillus subtilis, 4-7 pts. wt. Lactobacillus, 7-12 pts. wt. Bacillus mucilaginosus, 3-7 pts. wt. Bacillus megaterium, 4-7 pts. wt. Bacillus cereus, 7-12 pts. wt. photosynthetic bacteria and 2-6 pts. wt. alcohol yeast into stainless steel fermentation tank; adding 60-80 pts. wt. brown sugar and 500-1000 pts. wt. deionized water, stirring, adding 0.3-0.8 pt. wt. monopotassium phosphate, 0.3-0.8 pt. wt. magnesium sulfate heptahydrate, 6-15 pts. wt. rare earth component and 0.2-0.7 pt. wt. of 47 wt.% urea, and fermenting at 30-40 degrees C for 48 hours while stirring for 5 minutes every 30 minutes to obtain mixture; drying 800-1000 pts. wt. fulvic acid, 200-300 pts. wt. livestock manure, 80-120 pts. wt. soybean meal, 200-300 pts. wt. straw and 100-300 pts. wt. fruit residue, crushing and stirring; adding 40-70 pts. wt. mixture, stirring for 10-30 minutes, placing in bags and fermenting at 30-40 degrees C for 6-10 days.
