HYDROPONICS DEVICE, HYDROPONICS SYSTEM, LIFT MECHANISM, AND CULTIVATION/HARVESTING METHOD OF PLANT

摘要

To sufficiently perform draining work without requiring labor in harvesting by hydroponics.SOLUTION: A hydroponics device comprises a cultivation tank 2, a cultivation panel 3 and a lift mechanism 4. Liquid fertilizer 20 is stored in the cultivation tank 2. The cultivation panel 3 is mounted on the cultivation tank 2, and holds plants 6 to be cultivate by a posture at which roots 62 of the plants are positioned below. The lift mechanism 4 vertically moves the cultivation panel 3 within a range including the lower position P1 and the upper position P2. The lower position P1 is a position at which the roots 62 of the plants 6 are immersed into the liquid fertilizer 20. The upper position P2 is a position for draining at which the roots 62 is separated upward from the liquid fertilizer 20.SELECTED DRAWING: Figure 3
