Research Progress on Remediation and Conservation of Saline Alkali Soil
The improvement of saline alkali land was very important to improve the ecological environment and promote the sustain-able development of agriculture.According to the characteristics of saline alkali land, soil desalting remediation and fertilizer conser-vation in saline alkali soil were summarized, the advantages and disadvantages of these measures were analyzed, and then the view-point — "salt discharge is the basis while fertilization is the purpose"was proposed,in order to provide reference for the improvement of saline alkali soil.
