| 摘 要： | 水量不足是中国农作物产量提高的主要限制因素，而调亏灌溉是从作物生理角度出发，通过使作物受到一定的水分胁迫，在实现节水的同时，也获得了高产，对农业水资源的可持续发展具有重要意义。介绍了调亏灌溉的生理机制和增产机理，对作物调亏灌溉效应影响因素诸如调亏程度、调亏时间、施肥和灌溉方式等进行了概述，并提出了调亏灌溉中需要进一步研究的问题。

| 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. |
