PROBLEM TO BE SOLVED: To provide a watering apparatus capable of performing efficient watering by continuously adjusting a supply amount of water corresponding to illuminance of light with which plants are irradiated while increase in the size of the apparatus is suppressed.SOLUTION: A watering apparatus 10 has: a water storage tank 12 mounted on a frame 11; a supply part 13 which supplies water flowing out from the water storage tank 12 toward plants by water load; an electric proportional valve 14 which adjusts a flow rate of water flowing in the supply part 13; and an electric power supply source 15 which supplies electric power to the electric proportional valve 14. Furthermore, the watering apparatus 10 has: an illuminance sensor 16a which detects illuminance of light with which plants are irradiated; and a control part 18 which adjusts a valve opening degree of the electric proportional valve 14 on the basis of the illuminance detected by the illuminance sensor 16a.SELECTED DRAWING: Figure 1 |
