Abstract: Objects of the present invention are to provide a film for an agricultural greenhouse that can maintain a CO2 concentration necessary for the photosynthesis of plants even when ventilation is not performed and to provide an agricultural greenhouse using the film. The film for an agricultural greenhouse of the present invention is a cellulose film which contains a cellulose acylate resin and has an equilibrium moisture content of 4% to 8% at a temperature of 25° C., a relative humidity of 80% and a thickness of 60 to 200 μm.

Abstract: A greenhouse has a daylighting member supported by a frame. The daylighting member partitions a growing space for agricultural products from an outside world, and emits light, which has entered from a light incident surface on one side, from a light emitting surface on the other side. The daylighting member has a transparent substrate layer and a transparent light emitting layer provided closer to a light emitting surface side than the substrate layer. The light emitting layer has a refractive index of 1.54 or less, water absorbability, and an equilibrium moisture content of 10% or greater at 25° C. and a relative humidity of 80%.

Abstract: The agricultural material includes a cellulose acylate layer and a polymer layer. The cellulose acylate layer is formed of cellulose acylate. The polymer layer is provided on a first CA surface, which is one surface of the cellulose acylate layer. The polymer layer has a moisture permeation resistance of at most 7.5×10−4 m2·day/g per 1 μm of thickness and is formed of a polymer different from cellulose acylate. The agricultural material has a tear strength of at least 0.10 N.

Abstract: A packaging material for fruits and vegetables contains cellulose acylate having an acyl group. The cellulose acylate is cellulose acylate in which the hydroxy group of cellulose is esterified with a carboxylic acid, and has an acyl group. In the cellulose acylate of the packaging material for fruits and vegetable, an acyl group substitution degree, which is a rate of esterification of the hydroxy group of cellulose with a carboxylic acid, is within a range of from 2.00 to 2.97.
