Abstract: China's water resources are unevenly distributed,and drought seriously affects agricultural production.Many studies have shown that after a certain degree of drought stress,rehydrated crops will gradually return to normal growth state,and even accelerate the growth of crops,showing compensation effect.However,the extent of compensation to crops and how to adjust agricultural irrigation system according to the compensation effect and reduce the adverse effects of drought stress on agricultural production need to be clarified.Through summarizing the related research on the effects of drought rewatering compensation effect on the physiology,morphology and yield of various crops,the growth characteristics of crops after rewatering were further understood,which provided certain theoretical reference for improving the research on compensation effect of crop drought rewatering.

Key words: drought rehydration, compensation effect, drought stress, agricultural restoration
