The invention provides a multi-player compounded film-coated controlled release fertilizer which considers recycled thermoplastic resin as an inner coating layer and considers thermosetting resin as an outer coating layer and a production method thereof. The invention is that firstly the recycled thermoplastic resin is mixed with mineral powder and corn powder in certain proportion to be dissolved in the mixed solvent of n-butyl acetate and amyl acetate; the material is sprayed at fertilizer granules by a twin fluid nozzle in a heated boiling fluidized bed to form a thermoplastic resin film with the function of controlling and releasing nutrient which is transferred into a heated rotating drum fluidized bed to be sprayed with the mixed fluid of the thermosetting resin with curing agent and thinner; under the condition of rotating heating, the fast solidification reaction occurs at the outer layer of the thermoplastic resin filer to form a compact and bright thermosetting resin film. The product integrates the advantages of two kinds of resin films to realize the perfect combination of toughness and elasticity and achieve the same controlling and releasing effect while the film material consumption is reduced by 20 percent to 50 percent, which reduces the cost and as well as improves the interior controlling and releasing effect and the appearance quality of the product, and the product is applicable to the large scale industrialized production and popularization.
