NOVELTY - Preparing composite microbial fertilizer comprises deodorizing 500-600 pts. wt. of chicken manure and 250-300 pts. wt. of dairy cattle dung, mixing e.g. 0.4-0.6 pts. wt. of Stenotrophomonas, Aspergillus niger and Actinomycetes, fermenting, adding 3-8 pts. wt. of dihydrogen phosphate, again fermenting, drying, screening to obtain semi-finished product I, mixing e.g. 70-90 pts. wt. of wheat bran and 90-110 pts. wt. of calcium powder with 4-6 pts. wt. of water, fermenting, drying, sieving to obtain product II, mixing products I and II, fermenting, and drying.    USE - The composite microbial fertilizer is useful for wheat plant (claimed).    ADVANTAGE - The fertilizer improves soil structure and wheat yield.    DETAILED DESCRIPTION - Preparing composite microbial fertilizer comprises deodorizing 500-600 pts. wt. of chicken manure and 250-300 pts. wt. of dairy cattle dung using 2000-4000 million of photosynthetic bacteria under illumination intensity of 8000-12000 LUX at 12-24 degrees C, mixing 0.4-0.6 pts. wt. of Stenotrophomonas, Aspergillus niger and Actinomycetes, 3-5 pts. wt. of brown sugar, 90-110 pts. wt. of crushed straw, 15-20 pts. wt. of corn flour, fermenting at 50-60 degrees C for 7-10 days, adding 3-8 pts. wt. of ammonium dihydrogen phosphate, again fermenting at 50-60 degrees C for 2-3 days, drying until the moisture content is 5-40%, screening using magnetic separation method to obtain semi-finished product I, mixing 70-90 pts. wt. of wheat bran, 90-110 pts. wt. of calcium powder, 2-6 pts. wt. of brown sugar, 0.4-0.6 pts. wt. of Bacillus subtilis, lactic acid bacteria and ferrous sulfate with 4-6 pts. wt. of water, uniformly stirring, fermenting at 50-60 degrees C for 2-3 days, drying until the water content of 35-40%, sieving, magnetic selecting to obtain semi-finished product II, mixing 40-43 pts. wt. of product I, 26-30 pts. wt. of product II, 0.4-0.6 pts. wt. of Bacillus megaterium, Aspergillus niger, lactic acid bacteria, Streptomyces, photosynthetic bacteria and 1.5-2.5 pts. wt. of dinoflagellate, fermenting at 25-40 degrees C for 2-3 days, drying until the water content is lower than 15% to obtain base material, adding 72-74 pts. wt. of base material and 26-28 pts. wt. of chemical fertilizer, stirring, crushing into granule, and adding 70-90 pts. wt. of potassium sulfate, 15-25 pts. wt. of nitrogen fertilizer, 80-100 pts. wt. of amide nitrogen fertilizer, 45-50 pts. wt. of phosphorus pentoxide and 8-12 pts. wt. of zinc sulfate.
