Abstract: The research on spraying technology using GDR and the saving on water effect in dryland wheat was conducted in Taiyuan, Qingxu and Linfen during 2002—2005. The result showed that diluted 225 times, the yield-improving effects GDR5 was the best, the second was 300 times and 150 times, their yield—improving range was 5.2%~18.5%; sprayed during jointing and grouting (heading) the effect was the best, the second was only jointing. their yield—improving range was 10.2%~20.6%. the research of mix and spray on GDR showed that mixing using GDR1 and spraying in jointing using GDR5 the effect was the best. the saving on water effect of GDR5 was the best when each GDR was sprayed, The second was using GDR2 and GDR1. This study opens up a new area for applied grow regulator to winter wheat in dry land.
