NOVELTY - Preparation of microbial fertilizer comprises respectively absorbing fermented algae solution in powder sample; uniformly mixing single absorbed algae agent; mixing at least one of, e.g. calcium carbonate, montmorillonite and peat as sample (3); respectively absorbing fermented bacteria solution with sample (3); mixing single absorbed bacteria agent at certain ratio; adding lysine, methionine, glycine, and threonine into reactor; adding hydrogen peroxide and/or alcohol; reacting solution; and adding humic acid and/or citric acid to reactor with stirring.    USE - Preparation of microbial fertilizer.    ADVANTAGE - The method produces microbial fertilizer containing several organic microelements. It prevents plants from generating physiological diseases resulted from lack of microelements, increases supply of available nutrient of soil, improves soil physiochemical properties, promotes growth of plants, enhances crop yield, and improves agricultural product quality.    DETAILED DESCRIPTION - Preparation of microbial fertilizer containing several organic microelements comprises uniformly mixing at least one substance powder of distiller grains, mushroom residues, rice hulls, chitosan, peat, wheat hulls, bagasse, saw dusts, and plant ash; screening them in 0.1-2 cm screen to obtain sample (1); respectively fermenting Chroococcus Gardner, Eunotia lunaris, Chlamydomonas sajiao, Anabaena azotica, and Chlorella vulgaris; respectively absorbing fermented algae solution with 3-12 fold of weight of sample (1); uniformly mixing single algae agent of five absorbed algae agents at ratio of 5-55:0-30:0-35:0-35:10-50 to prepare sample (2); uniformly mixing at least one substance powder of calcium carbonate, montmorillonite, peat, lignite, zeolite, vermiculite, coal ash, bentonite, and kieselguhr; screening them with 0.1-2 cm screen to prepare sample (3); respectively fermenting Bacillus megaterium, Bacillus subtilis, Rhodopseudanonas palustris, Streptomyces jingyangensis, and Bacillus mucilaginosus; respectively absorbing fermented bacteria solution with 2-10 fold of weight of sample (3); uniformly mixing single bacteria agent of five absorbed bacteria agents at weight ratio of 10-50:0-35:0-30:0-25:10-55 to prepare sample (4); placing at least one of 5-35 wt.% lysine, methionine, glycine, and threonine into reactor; dissolving them with 10-35 wt.% water; adding 0.5-5.5 wt.% hydrogen peroxide and/or alcohol; reacting solution for 0.5-3.5 hours at 20-65 degrees C; adding 0-15 wt.% humic acid and/or citric acid to reactor with stirring; uniformly mixing (wt.%) ferrous sulfate (5-30), manganese sulfate (0-20), zinc sulfate (10-35), and ammonium molybdate (0-5) while adding them in reactor; performing complex reaction for 0.5-8 hours at 75-115 degrees C; pressurizing at 2-6 kg/cm2 after cooling solution to room temperature; solidifying and drying solution for 15-48 hours to obtain sample (5); and mixing (%) sample (2) (20-55), sample (4) (25-60), sample (5) (3-15), organic boron fertilizer (0-5), and livestock manure (0-8) to prepare final products.
