Regulated deficit irrigation (RDI) technology provides a new way to solve the contradiction between agricultural water supply-demand and the shortage of water resources. The paper briefly introduces the concept of RDI technology and its water-saving mechanism, and then describes the specific application of RDI technology in watermelon planting and the impact of RDI on watermelon growth dynamics, photosynthetic physiological characteristics, water productivity, and quality. It is concluded that timely and appropriate RDI of watermelon can not only improve the quality of the watermelon and maintain or even increase the yield, but also increase the water use efficiency (WUE). Finally, the main problems existing in the watermelon RDI technology are summarized, and its application is prospected, in order to obtain new results in the follow-up research of watermelon RDI.
