Abstract: In the context of increasing global water resource shortage,how to improve the agricultural water using efficiency is of great significance for the sustainable development of agriculture. As a kind of efficient water-saving irrigation technology with good prospect,alternate partial root-zone drip irrigation is considered to be one of the most promising irrigation technologies in the future. At present,scientists around the world have carried out a lot of researches on the impact of alternate partial root-zone irrigation on crop growth and physiology,and analyzed its water-saving mechanism,which needs to be summarized and sorted out urgently. This paper reviewed the development history of alternate partial root-zone irrigation,reviewed the effects of alternate partial root-zone irrigation on crop growth and development,yield and quality,summarized the physiological mechanism of this technology affecting crop water use efficiency,and prospected the future research direction of alternate partial root-zone irrigation. In order to provide reference for the research of water-saving irrigation mechanism and innovation of water-saving irrigation technology for crop alternate partial root-zone irrigatio.

Key words: Alternate partial root-zone irrigation, Water use efficiency, Yield, Quality, Water-saving mechanism
