PROBLEM TO BE SOLVED: To provide a plant cultivation device capable of changing a position of a light source irradiating light to an accommodated plant.SOLUTION: A plant cultivation device 1 which accommodates and cultures a plant 101 planted on a culture medium 100, and can make the accommodated plant 101 be viewed from outside, mounts the plant 101 planted on the culture medium 100 on a mounting table 10 and accommodates the plant in a transparent cylindrical body 20 detachably stacked on the mounting table 10. In the plant cultivation device, a ceiling part 30 is detachably mounted on the cylindrical body 20 and a light source 40 is detachably mounted on a light source installation part 23 formed on the cylindrical body 20. Consequently, the inside of the cylindrical body 20 can be irradiated.COPYRIGHT: (C)2015,JPO&INPIT【課題】収容した植物へ光を照射する光源の位置を変えることができるようにした植物栽培装置を提供する。【解決手段】栽培培地100に植えられた植物101を収容して栽培するとともに収容した植物101を外部から観賞できる植物栽培装置1は、栽培培地100に植えられた植物101を載置台10に載置して該載置台10に着脱可能に積み重ねられた透明な筒体20の内側に収容し、筒体20の上に着脱可能に天井部30を載置し、光源40を筒体20に形成した光源装着部23に着脱可能に装着して筒体20の内側を照射できるようにした。【選択図】図1
