The invention discloses a preparation method of compound fertilizer with high utilization rate for paddy rice. The preparation method comprises the following steps: uniformly stirring wormcast, peanutshell powder, sheep manure, vermiculite power and water; adding ammonium bicarbonate, potash magnesium sulfate fertilizer, plant ash, guano, precipitated phosphate, sodium molybdate and EDTA (Ethylene Diamine Tetraacetic Acid) chelated iron and zinc borate and uniformly mixing; adding modified rapeseed protein, uniformly stirring and granulating to obtain the compound fertilizer with the high utilization rate for the paddy rice. The fertilizer obtained by the preparation method disclosed by the invention, has the advantages of excellent water resistance, good granulation property and low cost; in addition, the demands of the paddy rice on main nutrient elements and trace elements in the whole growth period are satisfied; both production and income are increased by improving utilization efficiency of the fertilize
