Method and device for automatically adjusting drip irrigation flow according to solar irradiation intensity

The invention discloses a method for automatically adjusting drip irrigation flow according to solar irradiation intensity, which is characterized in that a photovoltaic module drives a water pump to press irrigation water into an irrigation pipe network, the irrigation pipe network consists of a plurality of irrigation branch pipes, and a measurement and control integrated valve is mounted at a water inlet of each irrigation branch pipe; the measurement and control integrated valves adjust the flow and pressure of the main water delivery pipe and the irrigation branch pipes by changing the opening degree of the valves, when the solar irradiation intensity is large, the multiple measurement and control integrated valves are automatically opened, the number of the irrigation branch pipes is increased, and therefore the irrigation area is increased, and the purpose of fully utilizing redundant irradiation intensity is achieved. When the solar irradiation intensity is small, part of valves are automatically clos
