Background

The salinization of soil refers to that salt segregants in the soil are increased and then continuously gathered to the surface of the soil, so that the physical and chemical shapes of the soil are changed, and certain harm is caused to growing plants. In general, groundwater and surface soil water are in relative dynamic equilibrium, but in arid regions (such as Tarim basins) with high soil evaporation, soil moisture moves up along soil capillaries, and the salinity in the soil also moves upwards along with the soil moisture. The water is evaporated and lost after reaching the surface layer of the soil, and the salt is accumulated on the surface layer of the soil, so that the soil is salinized repeatedly.

Common methods for treating soil salinization comprise water conservancy projects in which macro wells and pipelines are paved and biological treatment by using chenopodium plants and the like, wherein the water with the best effect belongs to high-pressure salt and salt washing, but the method is not suitable for being used in climatic regions because the method needs large-discharge water flow, and only can play a role in desalting and alkalizing soil, but cannot collect and utilize the salt in the soil.
