摘要:
Provided are an agricultural fluorine-resin film with which the harvest amount of a product is increased even in a greenhouse having high eaves, and a greenhouse. An agricultural fluorine-resin film containing fluorine resin and having a concavoconvex surface 1a on one surface, wherein the transmittance at a wavelength of 300-800 nm is 20-70%, and the transmittance T2 described below is 75% or higher. Transmittance T2: the transmittance, at a wavelength of 300-800 nm, of a laminate body obtained by laminating a testing film in which the concavoconvex surface 1a of the abovementioned resin film is completely filled with water, above which there is provided only an ethylene-tetrafluoroethylene copolymer having a thickness of 50 [mu]m, the transmittance of the testing film at a wavelength of 300-800 nm being 94%, and the arithmetic average roughness Ra of both surfaces of the testing film being 0.04 [mu]m.本發明提供一種即便於簷高較高的溫室中亦可使作物之收穫量增加之農業用氟樹脂膜及農業用溫室。一種農業用氟樹脂膜,含有氟樹脂且於一側表面具有凹凸面,其特徵在於:於波長300~800nm下之透射率為20~70%,且下述透射率T2為75%以上。透射率T2:以水完全填滿前述樹脂膜之凹凸面並於其上積層試驗用膜而成之積層體於波長300~800nm下的透射率;該試驗用膜係一厚度50μm且僅由乙烯-四氟乙烯系共聚物構成的膜,其於波長300~800nm下之透射率為94%,且兩側表面之算術平均粗糙度Ra為0.04μm。
