旱地冬小麦应用绿色抗旱剂增产效应研究

Study on Yield-improving Effects of "Green Drought Resistance Agent" on Winter Wheat in Dry Land

2002～2004年在山西临汾就旱地冬小麦应用绿色抗旱剂的使用效果进行了研究.结果表明:旱地小麦应用绿色抗旱剂具有较好的产量效应和生物学效应.GDR1号拌种剂较好地协调了旱地冬小麦的穗数、穗粒数、千粒重,使每hm2产量达3921.0kg,较对照增产9.42%:GDR5号在起身期叶面喷施,较对照增产12.49%.该项研究为旱地冬小麦应用生长调节剂开辟了新的领域.

Study on the applied effects of ＂Green Drought Resistance agent＂ on winter wheat in dry land was conducted during 2002～2004 in Linfen,Shanxi. The results showed that the application of ＂Green Drought Resistance agent＂ has good yield-improving effects and biological effects. ＂Green Drought Resistance agent NO. i＂ harmonized ear number,spike number and 1000-seed weight of winter wheat in dry land. The yield reached 3 921.0kg/hm^2,whose increase rate was 9.4G compared with the control. ＂Green Drought Resistance NO. 5＂ by leaf surface sprinkling in the period of getting up was 12.49 higher than that of the control in yield. This study opens up a new area for appying grow regulator to winter wheat in dry land.
