Agricultural land initial stage runoff collection irrigation system and method thereof
The invention discloses an agricultural land initial stage runoff collection irrigation system and a method thereof. The agricultural land initial stage runoff collection irrigation system comprises a drainage canal, a diversion canal, a drainage canal flow blocking weir, an initial stage runoff sensor, an electric water collection valve, a water collection tank, a lift pump, an agricultural irrigation pipeline and farmland irrigation spray nozzles. Square non-flush-period drainage exits are dug in the drainage canal flow blocking weir, and the electric water collection valve controlled by the initial stage runoff sensor is arranged on the diversion canal and is used for collecting initial stage runoff for daily farming irrigation. The agricultural land initial stage runoff collection irrigation system and the method thereof start from the perspective of reducing the pollution of agricultural initial stage runoff with high nitrogen and phosphorus load to water and utilizing agricultural crops to absorb the nitrogen and phosphorus load, an original canal system is utilized, the functions of collecting the initial stage runoff and ensuring smooth drainage of rainfall are achieved, and meanwhile the water resources are used for non-flush-period farmland irrigation. According to the agricultural land initial stage runoff collection irrigation system and the method thereof, the structure is simple, the implementation is easy, and flexible application can be achieved according to existing conditions of an application place.
