Regulated deficit irrigation and its application on fruit trees

Water resource is shortage in China, while fruit trees need much water to normal growth. So, the developing of water saving technique is inevitable in the orchard. The concept, research state and application of Regulated Deficit Irrigation (RDI) technique on fruit tree production are briefly presented in this study. Based on the state of research, existing obstacles and future development with the application of RDI technique in fruit tree production are discussed.
