The invention discloses a production method for a biological organic composite fertilizer containing humic acid chelate and belongs to the field of biological organic fertilizers. The biological organic composite fertilizer containing the humic acid chelate is produced by taking a mixture of chicken manure, pig manure and cow manure, corn straws, rape straws, melon vine, pine shells, chaff powder, rice bran and hulls, fungus dregs, beer grains, acid-sludge, starch dregs, soy sauce residure, aginomoto residues, oil residues, oil cakes, mildewed feeds, organic fertilizer fermentation agents, humic acid chelate ferrum, humic acid chelate copper, humic acid chelate magnesium, humic acid chelate zinc, humic acid chelate calcium and humic acid chelate manganese as raw materials through bacterium adding, full rotting, doping and granulation. The biological organic composite fertilizer containing the humic acid chelate has the advantages of low production cost, complete fermentation, thorough sterilization, high bioactivity, high humic acid chelate trace element content, zero odor, zero bacterium, convenience in use and the like.
