止される。The rainwater stored in the water tank rises by the capillary force of the porous gravel material and is supplied to the ground. At this time, since a water supply limiting sheet with an aperture ratio of 0 to 1 to 10% is arranged between the water tank and the ground, the rainwater supplied to the ground by the capillary force of the porous gravel material is raised. The amount of water is adjusted, and the amount of water is supplied according to the evapotranspiration of the ground and plants, and excessive supply is prevented.

Since the water tank 3 is filled with the porous gravel-like material 6, it is possible to use the ground 4 without using equipment for holding the ground 4 such as a plate on the water tank 3.
Can be provided, and the water 7 stored in the water storage tank 3 can be raised by the capillary force and supplied to the ground 4. The water storage tank 3 may be one or a combination of two or more as necessary. Therefore, the size may be determined according to the place where it is installed and the size of the housing 2, but the depth is, for example, 5 to 25.
It is preferably about cm. Further, for example, when the amount of water 7 in the water tank 3 is insufficient due to a small amount of rainfall or the volume of the water tank 3 is small, water other than rain water, for example, tap water is supplied. You can also

The porous granular artificial soil is, for example, a substance having a high basic exchange capacity, a substance having a high water retention capacity, and a porous material containing all or part of a warm-acting fertilizer, and is lightweight and has a water retention capacity. It is high in fertilizer retention, has good water permeability and breathability, and does not hinder root growth. As the artificial soil having such characteristics, for example, "Super resole" (trade name, manufactured by Crea Terra Co., Ltd.) can be used.

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.

により徐々に排水することができる。According to the mechanism described above, the rainwater storage type planting ground 1 stores rainwater in the water storage tank 3 and restricts the supply of the water 7 rising in the porous gravel-like material 6 by the capillary force as necessary. It is possible to grow the plant 8 without irrigation by supplying it to the ground 4 while adjusting the supply amount with the use sheet 11, but gradually discharging the water 7 stored in the water tank 3 to the outside of the housing 2. By providing the draining means 5 for storing the water, when the rain exceeds a predetermined amount, the water is temporarily stored in the water storage tank 3 and the draining means 5 is provided.
Can be gradually drained.

A holding plate 13 having a large number of holes or a net-like water passage is arranged at a position lower by a predetermined distance, for example, about 50 mm, and the lower end surface of the ground 4a on the holding plate 13 is the water storage tank 3
So that it is lower than the upper end surface of. By arranging in this way, when the water level of the water 7 in the water tank 3 is higher than the lower end surface position of the ground 4a on the holding plate 13, the water 7 once rises into the ground 4, Through the ground 4a on the holding plate 13 at the lower position, it is gradually drained to the drain groove 14 through the holding plate 13.
