A plant cultivation room provided with a plant cultivation area and an illumination lamp for irradiating light onto the upper surface side thereof, wherein at least a portion of the inner surface of the plant cultivation room comprises of a plant cultivation room inner surface constituent member composed of a material containing a far-infrared emission substance that emits and absorbs far-infrared and in which the emissivity of far-infrared is 0.6 or higher, and the surface of the illumination lamp has a coating layer containing the same far-infrared emission substance as the far-infrared emission substance of the plant cultivation room inner surface constituent member and is provided with a cooling and/or heating source having a cooling and/or heating surface composed of a material containing the same far-infrared emission substance as the far-infrared emission substance of the plant cultivation room inner surface constituent member. When the cooling surface of the cooling source is cooled, the far-infrared emission substance of the cooling surface absorbs far-infrared emitted by the plant cultivation room inner surface constituent member and the far-infrared emission substance of the illumination lamp. Also, when the heating surface of the heating source is heated, the far-infrared emission substance of the plant cultivation room inner surface constituent member and the illumination lamp absorb the far-infrared emitted by the far-infrared emission substance of the heating surface. In accordance with the present invention, it is possible to provide a plant cultivation system in a plant cultivation device having a temperature-regulating system with excellent comfort for both plants and workers, and with very high energy efficiency in a cultivation room space such as a plant factory. |
