The salinization of the soil will seriously affect the growth of plants and reduce crop yields. Landscaping in saline-alkali areas has always been a difficult problem for ecological construction.Research on the green construction of gardens in saline-alkali areas, adopt physical, chemical and biological scientific measures to improve the saline-alkali soil, realize the construction of saline-alkali soil greening, and play a positive role in the restoration of the ecological system of the saline-alkali area and improve the ecological defense capacity of the area.
