PROBLEM TO BE SOLVED: To provide a rice-growing plant adaptable to extreme area, such as desert.SOLUTION: The rice-growing plant comprises: a solar cell panel 7 provided on the roof of a factory building； a heat exchange device 6 for heat exchange with the outside air, the device being provided in the shade formed by the solar cell panel on the roof of the factory building； a body of the factory building provided under the ground； and a plant cultivation device 10 provided in a closed type cultivation room. An artificial light source 15 is provided with spectral emission characteristics and temporal luminescence characteristics, which are controlled in an enclosed space, and applies LED light to the side face of rice through a light guide plate 16 provided in the same direction as the growing direction of the rice. According to the growth of the rice, a plurality of cultivation buckets is moved laterally and downwardly to increase the distance between the ceiling of the body of the factory building and rice-growing bucket.SELECTED DRAWING: Figure 1【課題】砂漠などの極限地に対応する稲作プラントを提供する。【解決手段】工場建物の屋上に設けられた太陽電池パネル７と、工場建物の屋上において太陽電池パネルが形成する日陰に設けられた外気との熱交換装置６と、地中に設けられた工場建物の本体と、密閉型栽培室に設けられた植物栽培装置１０を備える。密閉空間内において分光発光特性及び時間発光特性が制御された人工光源１５を備え、稲の成長方向と同じ方向に設けられた導光板１６を通じて稲の側面へＬＥＤ光を照射し、複数の栽培バケットを横方向及び下方へ移動することで、稲の成長に応じて工場建物本体の天井と稲作バケットの間の距離を広げる。【選択図】図１
