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 vertical type seepage pipe salt elimination method for seashore saline soil. The method includes the following steps that first, land levelling and molding are conducted on a determined green land; second, a temporary open trench is formed in the levelled green land in a spaced mode, the width of the open trench is 50-60 cm, and the depth of the open trench is 90-100 cm; third, vertical type seepage pipes are mounted, the vertical type seepage pipes which are prepared in advance are placed at the bottom of the open trench, the shaft axis distance between the adjacent vertical type seepage pipes is 5 cm, a drain pipe is arranged at the bottom of each vertical type seepage pipe, and each drain pipe is directly communicated with a municipal well or a drainage well; fourth, original soil of the open trench is backfilled into the trench; fifth, secondary levelling and molding are conducted on the green land, and the original soil which is evenly mixed with a biological modifying agent and is 10 cm in thickness is additionally laid on the soil surface, and then conventional irrigation is carried out. By the adoption of the method, the quick desalting purpose can be achieved.

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...
