摘　　要：[目的]确定大花萱草杂交品种0812的耐干旱、耐瘠薄能力。[方法]对大花萱草杂交品种0812进行土壤干旱胁迫及不同施肥方式测试,观察其生长状态,并测定生理指标。[结果]大花萱草杂交品种0812在14 d干旱复水后的形态不影响其观赏;施肥与否对花期无太大影响,其薹高、花色、花径稍受肥料影响,但影响不显著。[结论]大花萱草杂交品种0812比较耐瘠薄,适合在干旱贫瘠土壤中种植。[Objective]To determine the ability of drought tolerance and barren resistance of the new species of Hemerocallis hybridus.[Method]Soil drought stress and different fertilization methods were tested,the growth state and physiological indexes were observed.[Result]It was observed that after 14 days of drought and water recovery,the morphology didn’t affect its viewing.Fertilization didn’t have much effect on flowering.Its bolting height,flower color and diameter were slightly affected by fertilizer,but the effect was not significant.[Conclusion]The hybrid species 0812 is relatively barren and suitable for drought and barren soil cultivation.
