The area of saline-alkali land is approximately 1×108 hm2 in China,of which about 0.37×108 hm2 can be utilized.Saline-alkali land is an important cultivated land reserve resource,with huge potential for development and utilization.Planting rice is an effective approach to utilize saline-alkali land.Rice root research is of great significance to explore the potential of saline-alkali paddy land to increase potential production.This paper briefly summarizes the current research status of saline-alkali stress in rice root system,and mainly focuses the effects of saline-alkali stress on root phenotype,stress physiology as well as its impact on yield formation.The prospects for future research are proposed.Overall analysis on stress morphology and physiological mechanism of saline-alkali stress in rice root system from multiple perspectives,clarification of the soil-root-yield interaction mechanism and construction of an ideal root system configuration based on excellent germplasm resources combined with breeding technology,will definitely provide a reference for tapping the potential of saline-alkali land rice to increase yield.
