Summary:The invention provides a release control method for peanut slow release fertilizer. The fertilizer is wrapped with release control films to achieve the purpose of release control. The release control films are prepared from, by weight, n/15-0.5 part of titanium dioxide, 1.5 parts of peat soil, 2 parts of clay, n/15-0.2 part of flatting powder wax, 5 parts of erucamid, 0.3 part of pentaerythritol stearate and 105 parts of polyethylene. A preparing method comprises the steps that all the raw materials are mixed and subjected to extrusion granulation with a double-screw extruding machine, then blow molding formation is carried out with a thin film blow molding machine, and the outer layer release control films can be obtained, wherein n is the number of staged slow-release effective days and is larger than or equal to 15 and smaller than or equal to 30. According to the release control method for peanut slow release fertilizer, different effective release control cycles can be designed for different growth stage
