Soil salinization is one of the main factors seriously restricting agricultural development and soil recycling.As China has a vast area of saline land,the restoration of saline soil is thus of great significance to increase the arable land area and crop yield.Saline soil is usually remediated by physical,chemical and biological methods.Biological remediation reduces soil salinity by utilizing biological metabolic activities.Compared with chemical and physical methods,biological remediation is more economical,environmentally friendly and efficient,so it is widely used in saline soil remediation.This study summarizes the harm of soil salinization and the current situation of soil salinization in China,discuesses the mechanism and research progresses of plant,microorganism and microorganism-plant combined remediation of saline soil,and prospects the application prospect of biological remediation of saline soil.
