A sensor is attached, a plant support is housed at the bottom of the lower container, the upper container and the lower container are vertically connected airtightly, and when culturing seedlings, the seedlings are placed in the plant support on the lower container. The culture solution and air will be supplied and discharged through the piping on the upper container side.

When the plant grows and needs to be moved, the upper container and the lower container are uncoupled and only the lower container is moved with the plant still housed therein. In this way,
It becomes possible to transport cultured plants without damaging them.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

FIG. 1 shows a sectional view of an embodiment of the present invention, and the culture container 10 has a three-layer structure consisting of an upper lid 11, a cylindrical upper container 12, and a lower container 13 with an open top. The lid 11 and the upper container 12 have mutual flange parts 11a, 1
2a through a gasket 14 and a fastener 15 such as a bolt or nut, and similarly, the lower flange portion 12b of the upper container 12 and the -L portion flange portion 13a of the lower container 13 are connected in an airtight manner. They are airtightly fastened by a fastener 17 with a gasket 16 in between, and are integrated as a whole.

An air supply port 18 and a liquid supply port 19 are provided on the side surface of the upper container 12.
, an exhaust port 20, and a drain port 21 are provided.

A filter 23 and an air pump 24 are connected to the air supply port 18 through a tube 22.
