[PROBLEMS] To improve the growth of plants on which walls are planted. A plant 20 planted in an opening 112 of a shelf 110 of a surface plate 100 is arranged in a vertical direction (with gravity and perpendicular to the ground). Since it grows in the reverse direction), the growth is improved compared to the case of growing (growing) substantially parallel to the ground. Since the water retention base 200 is sandwiched between the front plate 100 and the back plate 300 made of a heat insulating material, and the front plate 100 is not opened except for the opening 112 of the shelf 110, the temperature of the water retention base 200 is increased. Or a temperature fall is suppressed. As a result, the evaporation of moisture is suppressed. Furthermore, since the front plate 100 and the back plate 300 are made of a water-impermeable material, evaporation of moisture is further suppressed. Therefore, the temperature of the root 22 of the plant 20 is stabilized and drying is suppressed, so that the growth of the plant 20 is improved. [Selection] Figure 1 |
