Further, it is preferable to dispose a water-permeable sheet 12 between the water storage tank 3 and the ground 4 so as to overlap the water supply limiting sheet 11. The water-permeable sheet 12 is made of, for example, a non-woven fabric that allows water to pass through but does not allow the roots of the plant 8 to pass through. When the water-permeable sheet 12 does not pass through the roots of the plants 8, the roots extend into the water storage tank 3 and suck up the water 7 in the water storage tank 3 excessively, or the roots extending into the water storage tank 3 die and the water storage tank 3 Prevents the water 7 from decaying. The method for preventing the roots of the plants 8 from growing in the water tank 3 is not limited to the provision of the water permeable sheet 12, and for example, a substance containing the physiologically active substance trifluralin that inhibits the roots of the plants 8 is distributed. The method of setting is also adopted.
