DESCRIZIONE
An aquaculture device (100) is provided with the following: a growing chamber underground part (67) that contains therein an underground space in which the underground portion (1A) of a plant (1) grows, and that is configured so that the underground space is separated from an aboveground space in which an aboveground portion (1B) of the plant (1) grows; an underground temperature adjusting unit (2478) that adjusts the temperature of the atmosphere in the underground space; and a control unit (50) that controls the underground temperature adjusting unit (2478). The control unit (50) includes the following: a dormancy determination unit that determines whether the growing period of the plant (1) is a dormant period in which the leaves of the aboveground portion (1B) have died; and a temperature control unit which, if it was determined by the dormancy determination unit that the growing period of the plant (1) is a dormant period in which the leaves of the aboveground portion (1B) of the plant (1) have died, causes the underground temperature adjusting unit (2478) to adjust the temperature of the atmosphere in the underground space so that sprouting of the plant (1) is promoted.
