PROBLEM TO BE SOLVED: To provide a plant cultivation device that can suppress reduction of work efficiency caused by reflection sheet in performing maintenance or the like of plants being cultivated while efficiently irradiating plants with artificial light for example.SOLUTION: A plant cultivation device comprises: a first member capable of mounting cultivation vessels thereon a second member which is arranged with a space for the first member illumination members which are arranged with a space for the first member, and arranged on the first member rather than the second member a cultivation rack 10 which has a structure having a plurality of columnar members which fix the positions of the first member and the second member and reflection sheet 20 which is arranged at least on a side face of the cultivation rack in a longer direction, and has visible light reflectivity, in which the reflection sheet comprises fixing parts capable of setting the reflection sheet into a folded state along a horizontal direction with respect to the cultivation rack on a surface on the opposite side of a surface facing the cultivation rack.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】人工光を効率良く植物に照射しつつ、例えば、栽培中の植物の手入れ等を行う際に、反射シートによる作業効率の低下を抑制できる植物栽培装置を提供する。【解決手段】栽培槽を載置可能な第一部材と、第一部材に対して空間を設けて配置された第二部材と、第一部材に対して空間を設けて配置され、かつ、第二部材よりも第一部材側に配置された照明部材と、第一部材および第二部材の位置を固定する複数の柱部材とを有する構造体を有する栽培ラック10と、栽培ラックの少なくとも長手方向の側面に配置され、可視光反射性を有する反射シート20と、を備え、反射シートは、栽培ラックと対向する面とは反対側の面に、反射シートを栽培ラックに対して水平方向に沿って折り畳んだ状態とすることが可能な固定部を備える。【選択図】図3
