Abstract

The invention provides a salt drainage method adopting high-strength underground pipes. The salt drainage method comprises steps of constructing an underground pipe salt drainage system, laying a mixed layer and performing irrigation, wherein for the step of constructing the underground pipe salt drainage system, the pipe burying slope for the underground pipes ranges from 0.48 permillage to 0.60 permillage; for the step of laying the mixed layer, the volume ratio of zeolite to crushed stone in the mixed layer is (0.5-1):(0.8-3); for the step of performing irrigation, the irrigation flow velocity is 9-13m<3> / h. The invention further provides an application of the salt drainage method adopting the high-strength underground pipes in improvement of interpenetrated saline-alkali soil in North China. After improvement is performed for one year with the salt drainage method, an alkaline spot area occupies 12.6%-20.1%.

Description

technical field [0001] The present invention relates to a method for discharging salt by using a high-strength hidden pipe and its application in improvement of saline-alkali land, in particular to a method for discharging salt by using a high-strength hidden pipe and its application in improving saline-alkali land in North China The invention belongs to the technical field of rapid desalination and improvement of saline-alkali land. Background technique [0002] According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. In the arid and semi-arid areas of North China, the precipitation is small and the evaporation is large, and the salt dissolved in the water is easy to accumulate on the soil surface. In summer, the rain is abundant and concentrated, and a large amount of soluble salt seeps into the lower layer or flows away with the water. In spring, the...
