To provide a plant cultivation device capable of easily adjusting the concentration of oxygen dissolved in water, facilitating switching high/low concentration of oxygen dissolved, and supplying the appropriate water for growing to a plant.
The plant cultivation device includes: an air conditioning means 2 generating high oxygen concentration air, in which oxygen partial pressure is higher than air, and low oxygen concentration air, in which oxygen partial pressure is lower than air, and supplying them while switching them; a dissolving tank 3 supplied with water, communicating to the air conditioning means, supplied with the high oxygen concentration air or the low oxygen concentration air from the air conditioning means, dissolving the high oxygen concentration air or the low oxygen concentration air in water, and generating air dissolved water; and a water supply means 4 supplying air dissolved water which is generated in the dissolving tank to a plant.
