The pesticide machine 19 is connected to the water supply pipe for pesticide, and is used for supplying pesticides needed by plants. A fertilizer solution provided by the fertilizer machine 5 flows into the tank 6 along with the water flow path from the 6 water supply pipe for fertilizer 3 to avoid the fertilizer solution remaining in the water supply pipe for fertilizer 3, and a pesticide solution provided by the pesticide machine 19 flows into the tank 6 along with the water flow path from the water supply pipe for pesticide 20 to avoid the pesticide solution remaining in the water supply pipe for pesticide 20.
