As an important land resource, the poor physical and chemical properties of soil in saline alkali land are the biggest obstacle to plant growth and development in saline alkali land. Carrying out targeted research on saline alkali land improvement is of great significance to ensure food security and protect the ecological environment. In recent years, it is urgent to fully tap the potential of such areas in agricultural production and ecological greening through economic and effective original soil improvement measures. The existing research and engineering projects of saline alkali land treatment at home and abroad are mostly realized through water conservancy, physics, chemistry, biology and other measures, and tend to form a comprehensive treatment system integrating engineering, plant, microorganism and other technologies. Among them, salt separation layer + concealed pipe drainage is a more effective and commonly used engineering measure in saline alkali land treatment. Through the research and development of supporting new materials and processes, constantly improving the technical system can greatly promote saline alkali land treatment. This paper discusses the improvement of salt barrier in saline alkali soil
