Abstract: Water deficit is the limiting factor in the advancement of the crop yield, but Regulated Deficit Irrigation(RDI) embarks from the crop physiology angle.Through making the crops to receive the certain moisture deficient,it not only Saves water,but also obtains the high production.It has the vital significance to the agricultural water resources sustainable development. This article introduces the accent which owes the irrigation physiological mechanism and the production increase mechanism,and analyzes the irrigation effect influence factors such as RDI degree, RDI time,fertilization,irrigated mode, and so on.And proposes the accent which owes the question further to study in the RDI.
