Agricultural house, plant cultivation method using this agricultural house and heat ray reflective film structure

摘要

The agricultural house of the present invention and the method of cultivating a plant using the agricultural house are characterized in that the inside of the agricultural house is provided with at least CO ₂ supplying means for supplying carbon dioxide, heat shielding means and dehumidifying cooling means for cooling the inside of the agricultural house, The heat ray shielding means is formed by using a heat ray reflective film having an average transmittance of light of wavelengths of 400 to 700 nm of 80% or more and an average reflectance of light of 800 to 1200 nm of 70% or more, , Since a plurality of through holes are formed at predetermined intervals, it is possible to economically and efficiently cultivate plants with less energy to be supplied per harvest amount of plants, and to reduce the supply amount to plants, It is possible to cultivate the plants in the plants and the like and to prevent the quality deterioration such as discoloration and deterioration due to condensation. The heat ray reflective film structure of the present invention is obtained by alternately laminating at least two kinds of resin layers having different refractive indices, and is characterized in that an average transmittance of visible light (light having a wavelength of 400 to 750 nm) is 80% To 1100 nm) is not less than 70%, the thin film tape on which the slidability-imparting layer is formed on at least one side surface of the multilayer laminated film is trimmed or wefted and the filament yarn or yarn is woven or woven Wherein the thickness of the filament yarn or the yarn is 0.01 to 0.30 times the width of the fine strip tape and the distance between adjacent fine strip tapes is 0.1 to 0.5 times the width of the fine strip tape , It is possible to economically and efficiently carry out plant cultivation in an agricultural house using sunlight.
