Irrigation and drainage integrated device suitable for underground high water level

Abstract

The invention discloses an irrigation and drainage integrated device suitable for a high underground water level. The irrigation and drainage integrated device comprises a set of underground irrigation pipelines, an underground water conveying pipeline, a water storage pool body, a water inlet pipe, a water outlet pipe, a water pump and two automatic control valves of the water pump, wherein one end of each underground irrigation pipeline is connected with the underground water conveying pipeline; a water permeable film is mounted at the other end of each underground irrigation pipeline; the underground water conveying pipeline is connected with the water inlet pipe; the water inlet pipe is connected with the water storage pool body; the first automatic control valve is mounted on the water inlet pipe; one end of the water outlet pipe is connected with one side of the water inlet pipe; the other end of the water outlet pipe is connected with the water storage pool body; and the water pump and the second automatic control valve are respectively mounted on the water outlet pipe. According to the irrigation and drainage integrated device, redundant underground water can be drained under higher underground water level of farmland and is stored in the water storage pool body, and infiltrating irrigation is carried out through the underground irrigation pipelines under lower underground water level, so that the irrigation and drainage functions are achieved, the water resources are saved and high and stable yield of crops can be facilitated.

Description

technical field [0001] The invention relates to an irrigation and drainage device, in particular to a device suitable for the integration of infiltration irrigation and drainage of shallow-rooted crops. Background technique [0002] With the development of my country's economy and society, the contradiction between supply and demand of water resources will become more and more prominent. Global warming will lead to extreme weather such as drought and flood. It is an important way to improve the efficiency of water resource utilization in the South. [0003] Due to the imperfection of the underground drainage system or improper management and operation, the continuous high water level of the groundwater is often caused by repeated rainfalls, which leads to the lack of oxygen in the root system of the crops, affects the growth of the crops, and produces a large number of fallen flowers and fruits; on the other hand, seasonal drought will be serious. Affect the high quality, hi...
