摘要：
Provided is a cultivation device capable of controlling ground temperature at a low cost and at a relatively high accuracy. The cultivation device according to one embodiment of the present invention comprises a medium part in which a crop is planted and a cultivation liquid-feeding mechanism which feeds a cultivation liquid to the medium part, wherein the medium part has an area to which the cultivation liquid is fed by a capillary phenomenon, and a temperature-controlling mechanism, which controls the temperature of the cultivation liquid to be fed to the medium part, is further provided. It is preferred that: the cultivation liquid-feeding mechanism comprises a cultivation liquid tank for reserving the cultivation liquid, a reservoir tank for primarily reserving the cultivation liquid fed from the cultivation liquid tank, and a liquid supply part which supplies the cultivation liquid from the reservoir tank to the medium part； and the temperature-controlling mechanism is attached to the cultivation liquid tank or the liquid supply part. It is preferred that: the cultivation device further comprises an auxiliary cultivation liquid-feeding mechanism which feeds the cultivation liquid in the cultivation liquid tank to the medium part from above； the temperature-controlling mechanism is attached to the cultivation liquid tank； and the cultivation liquid, which is fed to the medium part by the auxiliary cultivation liquid-feeding mechanism, is circulated to the cultivation liquid tank via the reservoir tank.L'invention concerne un dispositif de culture apte à réguler la température du sol de manière peu coûteuse et relativement très précise.
