PROBLEM TO BE SOLVED: To provide the subject tray, which improves irrigation function of a plant-culturing mat, facilitates water management for the ground, and stabilizes the whole plant-culturing facility on the area on which it is placed. SOLUTION: This tray 1 is provided at least with a connection 2 outside of the tray, having an almost hook-shaped cross section and flaring at the top, on one side wall at the upper side of the wall, and another connection 3 outside of the tray, having an almost hook-shaped section and flaring at the bottom, an another side wall at the upper side of the wall. It is preferable that the upper side of the connection 2 is positioned higher than that of the connection 3 by cutting off the side end of the tray section at which the connection 2 is located. It is also preferable to divide inside of the water tank tray 1 into two or more water tank compartments by partitions, and to provide a cavity on the side wall at the upper side at a required point. A desired water tank tray 1 is selected from the water tank trays 1, and used with the connections 2 and 3 being alternately connected to each other on the area on which the trays 1 are to be placed side by side. |
