摘　　要：选用有特色花且市场潜力大的“红粉佳人”和“红珍珠”两种高山杜鹃为研究对象,探索了抹芽处理对其花期的影响。结果表明:抹芽处理与对照组花期有明显差异,可提前56 d左右,有效延长盛花期5 d左右,延长花期总历时30 d,提高成花率至71%~93%。有效地提前了花期、延长了花期和提高成花率,提升高山杜鹃“红粉佳人”和“红珍珠”的开花质量,增加观赏价值。为“红粉佳人”和“红珍珠”两种高山杜鹃提供了一种契合春节开花的花期管理技术。Two kinds of Rhododendron lapponicum"Pink beauty"and"Red Pearl"with distinctive flowers and high market potential were selected as the research objects to explore the effects of bud picking on their flowering period.The results showed that there were significant differences between the treatment and the control group in the flowering stage,which could advance the blooming stage by about 56 d,effectively prolong the blooming stage by about 5 d,extend the blooming stage for 30 d,and increase the flowering rate to 71%~93%.The flowering period is effectively advanced;the flowering period is prolonged and the flowering rate is improved;the flowering quality of Rhododendron lapponicum"Pink beauty"and"Red Pearl"is improved;the ornamental value is increased,which provides a new flowering management technique for two species of Rhododendron lapponicum"Pink beauty"and"Red Pearl".
