Abstract
In order to take advantage of the water resource in semiarid region of west Liaoning,the field experiment of limited supplementary irrigation scheduling was conducted during 2006～2007.The results showed that seed yield and water use efficiency were obviously effected by measure of limited supplementary irrigation.This study established the limited supplementary irrigation scheduling for spring maize in semiarid region of west Liaoning,which was based on the analyse on yield effect,irrigation efficiency and water use efficiency.The limited supplementary irrigation scheduling can provide the technical support for the large-scale field of supplementary irrigation on spring maize.
