PROBLEM TO BE SOLVED: To provide a plant cultivation apparatus which is capable of automating a plant growing work, increasing an effective cultivation area, having a simple structure in entirety, and improving productivity of plants.SOLUTION: There is provided a plant cultivation apparatus in which each stage of multistage plant cultivation shelves is configured by a plurality of horizontally movable pallets, and pallets are moved sequentially in a unit of pallet in a circulating manner. The apparatus comprises: a conveyance part equipped with a plurality of stages of rail part which conveys the plurality of pallets of each stage sequentially in a horizontal direction； first and second drive parts which are disposed on both end parts of the conveyance parts, equipped with a lifting mechanism for lifting up/down the pallet and a mechanism for drawing out/pushing out the pallet in a horizontal direction, moves the pallet between upper and lower stages and takes out/in the pallet to a corresponding rail part at a position of each stage； and light shielding means for blocking an internal space of at least one stage of a lower stage on which the pallet is arranged from outside during a germination period of seeds in a plurality of pallets which are arranged on the rail part of at least one stage on the lower stage side of the rail part of a plurality of stages of the conveyance part.【課題】植物生育作業を自動化でき、有効な栽培面積を増し、全体的にシンプルで、植物の生産性を向上できる植物栽培装置を提供する。【解決手段】多段の植物栽培棚の各段を水平移動可能な複数のパレットで構成し、パレット単位で順次に循環移動させる植物栽培装置であって、各段の複数のパレットを順次に水平方向に搬送するレール部を複数段備えた搬送部と、前記搬送部の両端部に配設され、前記パレットを昇降させる昇降機構と該パレットを水平方向に引き出し／押し出しする機構とを備え、パレットを上下段で移動させ、かつ各段の位置にてパレットを対応するレール部に出入する第１，第２の駆動部と、搬送部の複数段のレール部の下段側の少なくとも１つの段のレール部に配置される複数のパレット内の種子の発芽期間は、該パレットが配置された下段側の少なくとも１つの段の内部空間を外部と遮断するための遮光手段と、を具備する。【選択図】図１
