PROBLEM TO BE SOLVED: To provide a plant cultivation machine which withstands the weight of the nutrient solution by simply contacting the bottom plate, the side plate, and the end plate without using an adhesive and which can keep the whole form, the plant cultivation machine also corresponds to various kinds of cultivated items.SOLUTION: A plant cultivation machine consists of a cultivation bed 1, a support 2 which supports the cultivation bed 1, support implements which support the cultivation bed 1 from around, and a resin sheet which is put on the upper surface of the cultivation bed 1. The cultivation bed 1 is made of a plastic foam and has a bottom plate 10, side plates 11a and 11b which contact to the long side of the bottom plate 10, and end plates 12c and 12d which contact to the short side of the bottom plate 10. The support 2 has around frames 20 and a plurality of medium frames 23 provided at the interval capable of supporting the bottom face of the cultivation bed 1 in the around frames 20. The support implement comprises a plurality of first support members 7 that contact to the outside of the side plates 11a and 11b of the cultivation bed 1, and second support members 8 which contacts to the outer surface of end plates 12c and 12d of the cultivation bed 1, each support member 7 and 8 being mounted on the around frames 20.SELECTED DRAWING: Figure 2【課題】底板、側板、端板を接着剤を用いずに当接させるだけで、養液の重量に耐え、かつ全体の形態を保つことができ、また、多種類の栽培品目にも対応植物栽培機を提供する。【解決手段】植物栽培機は、栽培ベッド１と、栽培ベッド１を支持する支持台２と、栽培ベッド１を周囲から支える支え具と、栽培ベッド１の上面に被せられる樹脂シートとからなる。栽培ベッド１は発泡樹脂からなり、底板１０と、底板１０の長辺側と当接する側板１１ａ，１１ｂと、底板１０の短辺側と当接する端板１２ｃ、１２ｄとを有する。支持台２は、周囲枠２０と、周囲枠２０に栽培ベッド１の底面を支持可能な間隔で設けられる複数の中間枠２３とを有する。支え具は、栽培ベッド１の側板１１ａ，１１ｂの外面に当接する複数個の第１の支え部材７と、栽培ベッド１の端板１２ｃ，１２ｄの外面に当接する第２の支え部材８とを含み、各支え部材７，８が周囲枠２０に取り付けられている。【選択図】図２
