PROBLEM TO BE SOLVED: To provide an agricultural multilayer mulching film enhancing inhibitory effect of soil temperature rise and not dazzling an operator.SOLUTION: An agricultural multilayer mulching film comprises a light absorption layer containing carbon black on one surface, and a light reflection radiation layer containing fine powder of at least one kind of iron compound on the other surface. The thickness of the whole layer is 10 to 40 &mu；m, and the thickness of the light reflection radiation layer is 5 to 30 &mu；m. The reflectance of the light reflection radiation layer is 5 to 15% at a wavelength of 360 nm, 5 to 40% at a wavelength of 450 nm, and 30 to 60% at a wavelength of 700 nm. The content Wof titanium oxide fine powder is 1 to 5 g/mper unit area of a mulching film, and the content Wof the fine powder of at least one kind of iron compound is 0.1 to 5 g/m.【課題】地温上昇抑制効果を高め、作業者を眩惑しない農業用多層マルチフィルムを提供すること。【解決手段】一方の面にカーボンブラックを含有する光吸収層を備え、他方の面に鉄化合物の少なくとも一種の微粉末を含有する光反射放射層を備え、全層の厚みが１０～４０μｍの範囲にあり、さらに前記光反射放射層の厚みが５～３０μｍの範囲にあり、該光反射放射層の反射率が、波長３６０ｎｍで５～１５％、波長４５０ｎｍで５～４０％、波長７００ｎｍで３０～６０％であり、前記酸化チタン微粉末の含有量Ｗ１は、マルチフィルム単位面積当たり１～５ｇ／ｍ２の範囲であり、前記鉄化合物の少なくとも一種の微粉末の含有量Ｗ2は、０．１～５g/ｍ2であることを特徴とする農業用多層マルチフィルム。【選択図】図１
