Embodiment 1

[0028] Vertical seepage pipe salt drainage test site: Qidong Binhai Industrial Park Experimental Base

[0029] A vertical seepage pipe salt discharge method for coastal saline soil, comprising the following steps:

[0030] 1), firstly carry out the leveling and modeling of the land on the determined greening land; the modeling is designed to have undulating shapes;

[0031] 2) On the well-leveled green land, set a temporary open ditch at intervals, the width of the open ditch is 50cm, and the depth is 90cm; the width of the green space between adjacent open ditch is 5m;

[0032] 3) Installation of vertical seepage pipes: put the prepared vertical seepage pipes into the bottom of the open ditch, the distance between the axis lines of adjacent vertical seepage pipes is 5m, install a drainage pipe at the bottom of the vertical seepage pipes, The drainage pipe is directly connected with the municipal well or the drainage well; the vertical seepage pipe is a cement seepage pipe wi...

Abstract

The invention relates to a salt drainage method for vertical seepage pipes in coastal saline soil. The method comprises the following steps: 1) First, leveling and modeling the land on a determined green land; A temporary open ditch with a width of 50-60cm and a depth of 90-100cm; 3) Installation of the vertical seepage pipe: put the vertical seepage pipe prepared in advance into the bottom of the open ditch, adjacent to the axis of the vertical seepage pipe The line spacing is 5m, and a drainage pipe is installed at the bottom of the vertical seepage pipe, and the drainage pipe is directly connected with the municipal well or the drainage well; 4), the original soil of the open ditch is backfilled in the ditch; Sub-leveling and shaping, and spreading 10cm thick original soil evenly mixed with biological amendments above the soil surface; then carry out regular watering. The method of the invention can achieve the purpose of rapid desalination.

Description

technical field [0001] The invention relates to a salt discharge method for coastal saline soil, in particular to a salt discharge method for vertical seepage pipes for coastal saline soil. Background technique [0002] Due to the high salt content, shallow water level, and muddy compaction of the coastal saline soil, it is extremely difficult to plant green seedlings. Gardeners have racked their brains to solve the problem of coastal saline soil greening, and have adopted a variety of saline soil greening methods. At the beginning, the method of farmland soil replacement was used to solve the saline soil greening, but this method of destroying farmland for greening brought losses to food production. The second is that some methods are difficult for construction units to accept due to complicated operations and high input costs. Tianjin Hailin Gardening Environmental Technology Engineering Co., Ltd. has developed a number of soil improvement and vegetation construction tech...
