Problems solved by technology

[0004] However, the analysis of farmland irrigation systems at home and abroad shows that irrigation and drainage technologies that achieve self-circulation of farmland water and effective purification of pollutants are still rare.
Especially from the perspective of the system, through the rational construction of irrigation and drainage systems in large-scale irrigation areas, the combination of regional water resources self-circulation system and drainage system for wetland purification has not yet been seen.

Abstract

The invention relates to a self-circulating ecological water-saving irrigation and drainage system and a drainage method. Its structure is that there are internal and external water control gates between the outer river and the water-logged wet area, and a pumping station is installed in the water-logged wet area, and the drainage wetland farm ditch is connected with the water-logged wet area. The pumping station is grounded with underground irrigation pipes, and the underground irrigation pipes are connected The water pool and the water distribution pool are connected to the water inlet, and the water inlet is provided with a water diversion head. The water accumulation wet area is connected to the drainage wetland farm ditch, the drainage wetland farm ditch is connected to the drainage hair ditch, and the drainage wetland farm ditch and the field are ridges. Advantages: ensure the water environment required for the growth of crops; improve the utilization rate of farmland irrigation, effectively save water resources and increase crop yield; realize the full exchange of water bodies; improve the quality of river water environment; simple construction, easy to promote and implement, no need A large number of infrastructure projects can be widely used in farmland.

Description

technical field [0001] The invention relates to a self-circulating ecological water-saving irrigation and drainage system and a drainage method, which belong to the fields of farmland water conservancy irrigation and drainage technology, agricultural non-point source control technology and ecological restoration. Background technique [0002] my country is a country with severe shortage of water resources, and the utilization rate of water resources is also very low. Most of the reasons are caused by the waste of agricultural irrigation water in our country. Agricultural water is a renewable water resource. How to realize the self-circulation of farmland water through the optimal design and scientific layout of irrigation and drainage systems is an important way to solve the shortage of water resources. [0003] In terms of farmland drainage in irrigation areas, agricultural non-point source pollution occurs due to fertilization and spraying of pesticides on farmland. Agric...
