NOVELTY - An amino acid organic-inorganic fertilizer is produced by (A) aerobic fermentation and decomposition of organic substance; (B) ammonification treatment of organic substance and humic acid; and (C) chelation of organic substance and inorganic additive, pelleting and drying of the product. The step (C) involves adding secondary and microelement additive to treated material; stirring, and regulating pH using calcium superphosphate and ammonium bicarbonate; controlling water content, sealing, storing, and chelating; adding nitrogen (N), potassium (K), phosphorus (P) additive to reacted material.    USE - Method for producing amino acid organic-inorganic fertilizer (claimed).    ADVANTAGE - The method has low cost, and utilizes mineral and industrial, agricultural wastes which have wide source to prepare water-soluble humic acid and amino acid.    DETAILED DESCRIPTION - The amino acid organic-inorganic fertilizer is produced by (A) aerobic fermentation and decomposition of organic substance; (B) ammonification treatment of organic substance and humic acid; and (C) chelation of organic substance and inorganic additive, pelleting and drying of the product. The step (A) involves uniformly mixing Chinese medicine residues and animal manure at ratio of 1-1.5:1; adding fermentation strain (1-1.5 kg) in every square; regulating carbon-nitrogen ratio at 25-30:1 by controlling material ratio; and putting mixture to closed solar fermentation tent to carry out fermenting at high temperature until decomposing. The step (B) involves using crusher to crush fermented weathered coal and organic powder, and screening powder; mixing organic material and weathered coal at ratio of 0.8-1:1; adding calcium superphosphate (8-10%) and ammonium bicarbonate (5-10%), stirring, and regulating pH to 7-9; piling treated material on cement ground, covering plastic film, and storing; and regulating water content to 25-30% by adding mixed amino acid solution, and finishing ammonification treatment for 10-15 days. The step (C) involves quantitatively adding secondary and microelement additive to treated material; fully stirring, and using calcium superphosphate and ammonium bicarbonate to regulate pH to 7-9; controlling water content to 25-30%, sealing and storing for 6-8 days, and carrying out chelating; quantitatively adding N, K, P additive to reacted material; uniformly stirring, sending mixture to transfer granulator, and adding mixed amino acid solution at mass ratio of 8-15 to carry out pelleting; and drying product, controlling temperature to at 50-70 degrees C, and carrying out secondary chelating with drying. The secondary and microelement additive is prepared from (mass%): zinc sulfate (2-3), borax (3-4), ferrous sulfate (4-6), ammonium bicarbonate (9-17), ammonium sulfate (17-26), calcium superphosphate (14-17), magnesium sulfate (9-14), calcium nitrate (3-10) and ammonium molybdate (1-2). The N, P, K additive is prepared from (mass%): urea (17-50), monoammonium phosphate or diammonium phosphate (17-25), and potassium chloride or potassium sulfate (8-25).
