Embodiment

[0012] a. Select the root irrigation pipe with cuttings and grooves on both sides of the pipe wall as the drainage pipe. The diameter of the root irrigation pipe is 50mm, and the gap between the cuttings and the groove is 0.04mm. On the pipe wall of the root irrigation pipe per meter There are 50 water inlet holes with a diameter of 0.005mm;

[0013] b. Bury the selected root irrigation pipes in the farmland at a distance of 80cm, a slope of 2.2-3.3‰, and a depth of 60-80cm, and use them as underground hair-row hidden pipes, and connect them with the farmland with a width of 2m and a depth of 1.5m. The open drains are connected vertically, so that the farmland irrigation water can discharge the salt accumulated in the farmland soil into the farmland drainage system through the hair-type hidden pipe, so as to achieve the purpose of rapid salt washing and drainage;

[0014] c. Excavate a dredging ditch with a depth of 1 meter and a width of 1.5 meters on the side of the shallowe...

Abstract

The invention relates to a capillary drainage type buried pipe drainage method under a shallow buried condition. According to the method, root irrigation pipes provided with cutting wood and grooves in two sides are selected as drain pipes; and the selected root irrigation pipes are buried in a farmland at an 80 cm interval, a 2.2-3.3 permillage slope and a 60-80 cm depth, serve as underground capillary drainage type buried pipes, and are communicated perpendicularly with agricultural drainage open channels, so that farmland irrigation water drains salt accumulated in the farmland soil into an agricultural draining system, and fast salt washing and water draining are achieved. Experiments prove that the capillary drainage type buried pipes adopted in the method are good in drainage effect and long in service life.

Description

technical field [0001] The invention relates to a hair row type underground pipe drainage method under the condition of shallow burial, which belongs to the field of soil improvement. Background technique [0002] The present invention is aimed at heavy saline-alkali lands where the buried depth of the groundwater at the edge of the oasis in the arid area is within the range of 0.8-1.0m. Due to the strong jacking effect of the groundwater, the infiltration of the farmland irrigation water and the removal of salt will be blocked, so that the irrigation water will stay on the surface of the farmland. For more than a month, the farmland was in a state of salt accumulation for a long time and normal cultivation could not be carried out. In response to this problem, the traditional approach is (1) conventional open ditch drainage, that is, to excavate an open ditch for agricultural drainage in the farmland and connect it with the bucket row, and drain the excess water into the bu...
