Abstract

Abstract: Effects of irrigation mode on yields，grain qualities and water use efficiency were studied using four extensive-adaptation super rices( Guinongzhan，Yuxiangyouzhan，Hemeizhan and Shengtai 1) in a field experiment． Compared by conventional irrigation( CI), total grain number per panicle was increased，head milled rice rate ＆ protein content of grain improved under half amount of conventional irrigation( HACI), significantly． What is more， the amount of consumed water was remarkably decreased，water use efficiency markedly increased under HACI．

Key words: Irrigation mode, Extensive-adaptation super rice, Yield, Quality, Water use efficiency
