Abstract:
With global resources and environmental problems becoming more and more prominent, soil salinization has received widespread attention, and about 8% of the world’s land is threatened by salinization. China is a country where soil salinization is relatively serious, and the saline soil area accounts for 1/10 of the global saline soil area, and in recent years, under the influence of natural and human factors and other conditions, the soil under salinization stress is still developing, which seriously affects other aspects such as arable land resources, crop yield, and agricultural development. Therefore, it is of practical importance to improve the quality of saline soils and crop yields using economically rational and efficient management measures. This paper summarizes the causes and sources of soil salinization, and reviews the management pathways of saline soils from four aspects: irrigation and drainage measures, physical regulation, chemical improvement, and biological measures, to provide references for further research on saline soils management.
