Abstract

An irrigation system is provided. The irrigation system includes a reservoir for storing irrigation water, an electrolytic gas generator, a detector, and a control unit. The electrolytic gas generator is in fluid communication with the reservoir to output a first gas and a second gas generated by the electrolytic gas generator to the irrigation water. The detector is arranged in the water reservoir to detect the concentrations of dissolved first gas and dissolved second gas of the irrigation water to obtain dissolved gas concentration information. The control unit electrically connects to the detector and the electrolytic gas generator receives the dissolved gas concentration information and adjusts the voltage applied to the electrolytic gas generator according to the dissolved gas concentration information to control the type of gas generated by the electrolytic gas generator and the concentrations of dissolved first and second gas of the irrigation water.
