The invention provides an organic-inorganic composite biological fertilizer pesticide special for soybean. The organic-inorganic composite biological fertilizer pesticide is prepared from the following materials in parts by weigh: 40-50 parts of household garbage, 30-40 parts of mushroom slag, 20-25 parts of vinasse, 15-20 parts of humic acid, 10-13 parts of monocalcium phosphate, 12-14 parts of urea, 10-12 parts of potassium nitrate, 10-12 parts of quail feather, 20-24 parts of modified sepiolite, 3-4 parts of quispualis indica, 3-4 parts of stone-like omphalia, 4-6 parts of broom cypress fruit, 4-6 parts of rhizome nardostachyos, 4-6 parts of radix euphorbiae lantu, 0.1-0.2 part of boric acid, 0.05-0.1 part of sodium molybdate, 1-1.5 parts of zinc sulfate, 0.7-1.0 part of manganese sulfate, 5-7 parts of magnesium sulfate, 1-2 parts of nitrogen-fixing bacteria preparation and 3-5 parts of wintergreen oil. According to the invention, multiple organic wastes are mixed and then fermented so as to be changed into green organic fertilizer, environmental pollution is reduced, fermenting organic matter are mixed with inorganic fertilizer, and Chinese herbal medicine juice with insecticide function is added, therefore, the nutrition is more complete, and the sterilizing effect is increased. By applying the fertilizer, the quality of the soybean can be effectively improved, the soybean has green leaves and more flowers, the flowering period is prolonged, and the yield is improved.
