The invention belongs to the technical field of fertilizers and particularly relates to a synergistic feed regulator and a production method thereof. The synergistic feed regulator comprises the following raw materials in parts by weight: 50-60 parts of a bio-active humic acid powder, 20-25 parts of a charcoal powder, 10-20 parts of tea seed cakes, 5-7 parts of calcium superphosphate, 3-6 parts ofammonium chloride, 3-5 parts of microbial strain, 3-5 parts of carboxymethyl chitosan, 1-2 parts of potassium chloride, 0.4-0.6 part of sodium citrate, 0.5-1 part of potassium polyacrylate and 10-15parts of a medical stone powder. The used raw materials in the invention are wide in source and low in cost, and the produced synergistic feed regulator has the effects of fixing nitrogen, dissolvingphosphorus and potassium, improving the fertilizer utilization ratio, supplementing nutrient elements and the like. Moreover, the synergistic feed regulator is added into a fertilizer preparation master batch to be mixed so as to prepare a fertilizer, so that the nutrients of the prepared fertilizer are increased, and the fertilizer applied to soil can achieve the effects of increasing the contentof organic matters in the soil, improving physical and chemical properties of the soil, promoting crop growth and improving the yield and quality of the crops.
