摘　　要：2002—2005年在山西太原、清徐和临汾就旱地冬小麦应用绿色抗旱剂的喷施技术及节水效应进行了研究。结果表明:GDR5号喷施以稀释225倍的增产效果最为显著,其次为稀释300倍和150倍,增产幅度为5.2%￣18.5%;GDR5号喷施以起身喷+灌浆(挑旗、抽穗)喷的效果最好,其次为起身喷。增产幅度为10.2%￣20.6%;绿色抗旱剂拌+喷试验表明以GDR1号拌种+GDR5号起身期喷施效果最显著。各个绿色抗旱剂叶面喷施的节水效果以GDR5号的较高,其次为GDR2号和GDR1号。该项研究为旱地冬小麦应用生长调节剂开辟了新的领域。Spraying technology of GDR and saving water of winter wheat in dry land were studied in Shanxi Taiyuan, Qingxu and Linfen from 2002 to 2005. The result showed that the yield-improving effects of spraying GDR No.5 diluted 225 times was the better than 300 times and 150 times, which improving yield from 5.2% to 18.5%. sprayed at raising stage and at grain filling stage, GDR No.5 has the best effect.and sprayed only at raising stage has the best effect. Spraying GDR No.5 can improving yield from 10.2% to 20.6%. The research of GDR dressed and sprayed experiment showed that seal dressed by GDR No.1 and GDR No.5 sprayed at raising stage has volume effect, spraying GDR No.5 has the best effect of saving water among all GDR No.5 ,and GDR No.2 and GDR No. 1 have the second effect. This research can open a new area for used of growth regulator to winter wheat in dry land.
