The area of saline alkali land in China accounts for one tenth of the total area of saline alkali land in the world,which seriously restricts agricultural production.It is very important to repair and make good use of saline alkali land.At present,the methods of saline-alkali land remediation include chemical remediation,engineering remediation and bioremediation,among which bioremediation is an economical,efficient,green and sustainable method.Bioremediation improves the soil and environment of saline-alkali land through biological resources such as plants and microorganisms.Halophytes can grow and reproduce in saline-alkali soil and have the ability to repair high concentration saline-alkali soil,while common crops can enhance their salt tolerance through gene mining and variety cultivation to achieve the purpose of repairing saline-alkali soil.Microorganisms can also be used to improve crop salt tolerance or degrade salt and alkaline substances in saline-alkali soil.Bioremediation is a green and environmentally friendly method for the remediation of saline-alkali land,which is in line with the development strategy of sustainable agriculture and circular economy in China.
