PROBLEM TO BE SOLVED: To provide an agricultural curtain material capable of suppressing a rise in humidity during keeping of the interior of a greenhouse warm, having good heat retaining properties, realizing the minimization of a shade on crops due to excellent converging properties, scarcely storing thermal energy of the material itself, good in heat insulating properties at the time of shading and scarcely affecting the readjustment after stretching and the greenhouse structure, etc., due to ultralow shrinkability and excellent in economical efficiency. SOLUTION: The characteristic of this agricultural curtain material is to use a woven cloth comprising warp yarns and weft yarns of 30-300 denier and have 40-70% shading ratio. The material of the woven cloth is preferably selected from a synthetic resin having 0-5% official moisture regain and the material of the woven cloth is preferably a polyester. The air permeability according to the method B of JIS L 1096 is preferably 1-100 cc/cm2.s and the woven cloth is preferably treated by thermosetting.
