NOVELTY - Preparing efficient microbial organic fertilizer, involves obtaining components e.g. brown sugar, glucose, amino acid composite powder, filtrate of rice bran, magnesium sulfate, ferrous sulfate, monopotassium phosphate, nitric oxide, vitamin B1, 150 pieces of vitamin C, fibrinolysis Bacillus, paddy Bacillus, Trichosporon pullulans, B.cereus, photosynthetic bacteria, bacteria, agent for accelerating decomposing, and adding the components into a bag, and sealing and coding the finished product.    USE - The method is useful for preparing efficient microbial organic fertilizer which is useful for crops.    ADVANTAGE - The method is simple and cost-effective, and has wide raw material source. The organic fertilizer improves yield of crops to 8-31%.    DETAILED DESCRIPTION - Method for preparing efficient microbial organic fertilizer, involves (a) obtaining component A chosen from (in kg) brown sugar (6), glucose (2.5), amino acid composite powder (3), 10 kf of filtrate of rice bran (5) after boiled with water, magnesium sulfate (20), ferrous sulfate (20), monopotassium phosphate (30), nitric oxide (30), vitamin B1 (150), 150 pieces of vitamin C, fibrinolysis Bacillus (3.6), paddy Bacillus (3.6), Trichosporon pullulans (4), B.cereus (3), photosynthetic bacteria (3), 301 bacteria (3), and agent for accelerating decomposing (4), (b) obtaining component B chosen from (in kg) brown sugar (5), amino acid composite powder (1), fermentation bacterium (3) and lactic acid bacteria (1), (c) obtaining component C chosen from brown sugar (5), glucose (3), magnesium sulfate (60), ferrous sulfate (60), nitric oxide (100), 200 pieces of vitamin B1, B.mucilaginosus (4), yeast (2), B.cereus (4), phosphor bacteria (3.5), potassium bacteria (3.5) and Thiobacillus (4), (d) obtaining component D chosen from 80 meshes of plant straw powder (1800), and 80 meshes of chicken dung powder (200), (e) obtaining 80 meshes of humic acid mineral powder (2000), and (f) adding the components (a)-(e) into a bag (as 20 kg/bag), filling the bag in a plastic bag, coating the plastic bag, and sealing and coding the finished product.
