<p>An agricultural/horticultural greenhouse configured such that: at least some of the inner surface of the greenhouse is composed of house-interior-surface constituent members configured using materials containing a far-infrared-ray-emitting substance that radiates/absorbs far-infrared rays and has far-infrared emissivity of at least 0.6; heating or cooling pipes are arranged inside, on the surface of, or near the soil of the agricultural/horticultural greenhouse; materials containing a far-infrared-ray-emitting substance that is identical to the far-infrared-ray-emitting substance of the house-interior-surface constituent members is preferably mixed into the soil; far-infrared radiation emitted by the far-infrared-ray-emitting substance in the heated soil is absorbed by the far-infrared-ray-emitting substance of the house-interior-surface constituent members when the soil is heated by the heating pipes; and far-infrared radiation emitted by the far-infrared-ray-emitting substance in the cooled soil is absorbed by the far-infrared-ray-emitting substance of the house-interior-surface constituent members when the soil is cooled by the cooling pipes. The present invention allows the heating or cooling temperature to be efficiently adjusted for soils and plants in greenhouses used for agriculture or other purposes.</p> |
