The invention discloses a drip-irrigation annular field pipe network for reversing water flow based on capillary pipes. The pipe network comprises a main pipe, the main pipe is perpendicularly provided with a branch pipe a and a branch pipe b which are parallel to each other, a plurality of parallel drip-irrigation capillary pipes are perpendicularly arranged between the branch pipe a and the branch pipe b and are parallel to the main pipe, each drip-irrigation capillary pipe is provided with a plurality of drip-irrigation emitters, a water inlet valve a is installed at the end, close to the main pipe, of the branch pipe a, a flush valve a is installed at the other end of the branch pipe a, a water inlet valve b is installed at the end, close to the main pipe, of the branch pipe b, and a flush valve b is installed at the other end of the branch pipe b. The invention further discloses an irrigation method of the drip-irrigation annular field pipe network. The drip-irrigation annular field pipe network and the irrigation method solve the problems of dirt siltation of capillary pipes, time and labor waste during flushing of the capillary pipes and high cost.
Description
technical field [0001] The invention belongs to the technical field of water-saving irrigation, and in particular relates to a ring-shaped field pipe network for drip irrigation based on capillary reversing water flow, and also relates to an irrigation method for the ring-shaped field pipe network for drip irrigation. Background technique [0002] Drip irrigation is an advanced water-saving irrigation technology, which is widely used in arid and water-scarce areas in my country. In order to alleviate the shortage of water resources, researchers began to explore the use of high-sand content surface water, brackish water and recycled water as drip irrigation water sources, and integrated water and fertilizer technology. However, there are sediment, minerals, organic matter, microorganisms, etc. in the irrigation water of this technology. Even if a filter is installed in the drip irrigation system, some very fine solid particles will enter the pipe network; when the pipeline fl...
