在室内水培和大田条件下研究了冬小麦使用旱宝Ⅰ号与微肥混合拌种的节水增产效果。结果发现：在渭北旱塬干旱条件下，旱宝Ⅰ号拌种对冬小麦成苗、产量和ＷＵＥ有明显促进作用，与对照相比，出苗期可提前３ｄ，出苗率提高４．５％，产量增加１０％，ＷＵＥ提高９．９％。肥力条件对旱宝Ⅰ号的效果有明显影响，较好肥力条件有助于发挥旱宝Ⅰ号的效果。与Ｍｎ、Ｂ等混合拌种后对成苗及产量和ＷＵＥ有显著促进作用，但与旱宝Ⅰ号单独拌种的效果无显著差异 Under hydroponics and field conditions in laboratory, the effect of water saving and yield increase of mixed seed dressing of Chaba I and micro-fertilizer for winter wheat was studied. The results showed that under dry conditions in Weibei arid highland, dry seedling Ⅰ could significantly improve the seedling yield, WUE and yield of winter wheat, compared with the control, the seedling emergence rate increased by 3d and the germination rate increased by 4.5% Production increased by 10% and WUE by 9.9%. Fertility conditions have a significant impact on the effect of Chaba I, better fertility conditions help play the effect of Chaba I. Mixed with Mn, B and other mixed seedlings on the seedling and yield and WUE had a significant role in promoting, but with the dry treasure I single seed dressing effect was no significant difference
