NOVELTY - A composite microorganism bacterial manure comprises (mass.%): plant ash (20-25), fermentation medium (30-65), and mixed bacterial liquid (15-50). The fermentation medium is prepared by components including chitin, lecithin, calcium phosphate or monopotassium phosphate, ferric sulfate, sodium chloride and water. The mixed bacterial liquid is mixed by self nitrogen-fixing bacteria liquid, organic-phosphorus-discomposing bacteria, and inorganic-phosphorusdiscomposing bacteria.    USE - As composite microorganism bacterial manure (claimed) as fertilizer for Cunninghamia lanceolata seedling.    ADVANTAGE - The composite microorganism bacterial manure reaches to replenish the nitrogen and phosphorus in the soil; promotes the growth of the plant; provides Cunninghamia lanceolata seedling growing in 0.5 years, and the month growth rate of 90.5% which is higher than that of the blank control of 14.3-39.6%.    DETAILED DESCRIPTION - A composite microorganism bacterial manure comprises (mass.%): plant ash (20-25), fermentation medium (30-65), and mixed bacterial liquid (15-50). The fermentation medium is prepared by components including (wt.%): chitin (50-99), lecithin (0.01-0.2), calcium phosphate or monopotassium phosphate (0.5-1), ferric sulfate (0.02-0.05), sodium chloride (0.1-0.5) and water (up to 100). The mixed bacterial liquid is mixed by self nitrogen-fixing bacteria liquid, organic-phosphorus-discomposing bacteria, and inorganic-phosphorus-discomposing bacteria with 15-50 mass.% concentration according to 1:1:1-1.5:1:1 of volume ratio. An INDEPENDENT CLAIM is included for preparation of the composite microorganism bacterial manure involving: (1) dosing the fermentation medium comprising (wt.%): chitin (50-99), lecithin (0.01-0.2), calcium phosphate or monopotassium phosphate (0.5-1), ferric sulfate (0.02-0.05), sodium chloride (0.1-0.5) and water (up to 100); (2) diluting the self nitrogenfixing bacteria liquid, and organicphosphorus-discomposing bacteria, and inorganic-phosphorus-discomposing bacteria by sterile water into 15 mass.% of concentration, mixing and uniformly stirring according to 1 to 1 to 1-1.5 to 1 to 1 of volume ratio to obtain the mixed bacterial liquid; (3) adding the mixed bacterial liquid in the fermentation medium, uniformly mixing, fermenting for 24-48 hours at 25-30 degrees C, adding plant ash, fermenting at 25-30 degrees C to not less than 0.2 billion/g of total bacteria count.
