PROBLEM TO BE SOLVED: To provide an agricultural film formed of a polyolefin based resin which can maintain its wavelength conversion effect even when it is stretched out at outdoor for a long period of time and in which a fluorescent substance is properly dispersed.SOLUTION: The agricultural multilayer film has a laminated structure with three or more layers having at least an outer layer, an intermediate layer and an inner layer and is formed of a polyolefin based resin composition. It contains a specific fluorescent substance of 0.1-5 wt.% in terms of the polyolefin based resin composition in the whole layers of the film. In the agricultural multilayer film, when the content rate (wt.%) of the fluorescent substance in the intermediate layer is X, the content rate (wt.%) of the fluorescent substance in the inner layer is Y and the content rate (wt.%) of the fluorescent substance in the outer layer is Z, X>；Y and X>；Z.【課題】長期間屋外に展張しても波長変換効果を持続し、かつ、当該蛍光物質が良好に分散したポリオレフィン系樹脂からなる農業用フィルムを提供すること。【解決手段】少なくとも外層、中間層、内層を有する３層以上の積層構造を有するポリオレフィン系樹脂組成物からなる農業用多層フィルムであって、フィルム全層中のポリオレフィン系樹脂組成物に対して特定な蛍光物質を０．１～５重量％含有し、中間層中の蛍光物質含有率（重量％）をＸ、内層中の蛍光物質含有率（重量％）をＹ、外層中の蛍光物質含有率（重量％）をＺとしたとき、Ｘ＞Ｙ、かつＸ＞Ｚであることを特徴とする農業用多層フィルム。【選択図】なし
