NOVELTY - A tobacco composite microbial fertilizer comprises (wt.%) active functional bacteria (4-6), organic fertilizer (45-55), and inorganic fertilizer (40-50). The active functional bacteria comprise Bacillus megaterium powder, Bacillus mucilaginosus powder, Bacillus amyloliquefaciens strain HMI-23 powder, and Brevibacillus laterosporus powder.    USE - Tobacco composite microbial fertilizer used for promoting seedling growth.    ADVANTAGE - The fertilizer has improved utilization rate of fertilizer, increases soil organic matter, promotes rhizospheric microorganism propagation, improves physical and chemical properties and biological activity of the soil, provides comprehensive and balanced nutrition during seedling growth period, and can reduce soil-borne disease and increase yield and quality of cured tobacco.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the tobacco composite microbial fertilizer, comprising:    (A) preparing organic fertilizer by screening and crushing dried chicken manure, rape seed cake, and straw, and mixing, adjusting carbon/nitrogen ratio of the mixture to 20-30, adjusting water content to 50 wt.%, adding organic matter, decomposing and composting to obtain decomposed organic fertilizer;    (B) uniformly mixing organic fertilizer with active functional bacteria powder, adding borax and ammonium molybdate, adjusting water content to 32-38 wt.%, fermenting, when temperature reaches 50 degrees C, turning for 2-3 times every day till the temperature reaches to 40 degrees C, pelletizing obtained biological fertilizer, drying, cooling and sieving to grain size of 1-4.75 mm, and coating with micropore macromolecule semipermeable membrane material to obtain active functional bacteria-organic fertilizer composite component;    (C) mixing urea, potassium sulfate, potassium nitrate, calcium superphosphate and sepiolite powder, granulating, drying, sieving particle to 14.75 mm, coating micropore macromolecule semipermeable membrane material to obtain inorganic fertilizer component; and    (D) uniformly mixing the active functional bacteria-organic fertilizer composite component and inorganic fertilizer component, and packing to obtain the finished product.
