Abstract
An agricultural fluorine-resin film and a greenhouse that can increase yield of crops even in high-eave houses are provided. In the agricultural fluorine-resin film containing fluorine-resin, one surface has an uneven surface, a transmittance at a wavelength of from 300 to 800 nm is from 20% to 70%, and a transmittance Tbelow is 75% or more. Transmittance T: Transmittance of a laminate at a wavelength of from 300 to 800 nm, obtained by laminating the resin film and a test film, in which the uneven surfaceof the resin film is completely filled with water, and the test film which has a thickness of 50 μm, is formed of only an ethylene-tetrafluoroethylene copolymer, and has a transmittance at a wavelength of from 300 to 800 nm of 94% and an arithmetic average roughness Ra of both surfaces of 0.04 μm is laminated on the resin film.
