technical field

The utility model relates to the technical field of equipment for inhibiting saline-alkali infiltration, in particular to a device for inhibiting saline-alkali infiltration.

Background technique

Soil salinization refers to the increase of salt ions in the soil, which continuously accumulate on the soil surface to change the physical and chemical shape of the soil and cause certain harm to the growing plants. Under normal circumstances, groundwater and surface soil water are in a relative dynamic balance, but in arid regions (such as the Tarim Basin), soil evaporation is large, and soil moisture moves up along the soil capillary, and the salt in the soil also moves upward with the soil moisture. sports. After the water reaches the soil surface, it is lost by evaporation, while the salt accumulates on the soil surface, which causes soil salinization.

Common methods of controlling soil salinization include water conservancy projects with large wells and pipelines, and biological treatment using camel hair and quinoa plants. It needs to use a large amount of water flow, so it is not suitable for use in arid regions, and this method can only achieve the effect of soil desalination, but cannot collect and utilize the salt in the soil.
