PROBLEM TO BE SOLVED: To provide a plant cultivation system low in cost and rich in extensibility which includes a movable cultivation device equipped with a cultivation tank in which a medium for cultivating plants is put.SOLUTION: A plant cultivation system includes: a plurality of rails 10 two round bars 20 which are laid parallel to each other so as to straddle the plurality of rails 10 a cultivation device 30 which includes a plurality of support posts 31 installed upright in two rows and a cultivation tank 32 supported by the plurality of support posts 31 for putting in a medium for cultivating plants and a plurality of support devices 40. Each of the support devices includes: a support member for supporting the lower end part of each of the support posts and a pair of rollers which ride on the upper surface of each of the round bars on the obliquely right and obliquely left sides, and which rotate according to the rotation of the round bar. The support devices are each provided on each of the plurality of support posts, and put the cultivation device 30 on the two round bars 20 in cooperation with one another.COPYRIGHT: (C)2015,JPO&INPIT【課題】 本発明は、植物生育用の培地が収容される栽培槽を備えた栽培装置を可動式とした植物栽培システムに関し、コストが安く、かつ拡張性に富んだ植物栽培システムを提供する。【解決手段】 複数本のレール10、互いに平行に複数本のレール10に跨がるように横たえられた2本の丸棒20、2列に立設した複数本の支柱31と、それら複数本の支柱31に支持された、植物生育用の培地が収容される栽培槽32とを有する栽培装置30、および支柱の下端部を支持する支持部材と、丸棒の左右方向両側斜め上に乗り、丸棒の転がりに応じて回転する一対のコロとを有する、複数本の支柱それぞれに対応して備えられ、共同して、栽培装置30を2本の丸棒20の上に載せる複数の支持装置40を備えた。【選択図】 図1
