摘　　要：本文对贵州百里杜鹃风景区马缨杜鹃、迷人杜鹃和露珠杜鹃3个主要建群杜鹃花种进行了开花习性及花期规律调查和研究,基本了解了这3种杜鹃花各自的开花习性以及3种杜鹃花之间的花期规律。马缨杜鹃单花序盛开时间大约在25～30天,露珠杜鹃及迷人杜鹃单花序盛开时间大约在25天左右。开花率高峰出现日,露珠杜鹃早于迷人杜鹃5天左右,迷人杜鹃早于马缨杜鹃5天左右。迷人杜鹃虽然与马缨杜鹃基本同时进入盛花期,但早5天左右完成盛花期。Tree main rhododendron species, namely Rhododendron delavayi Franch. , R. irroratum Franch. , and R. agastum Balf. f. et W. W. Sm. were investigated and studied for their flowering characteristics. The results showed that the time of full blossom stage of R. delavayi Franch was 25 -30 days, while that of R. irroratum and R. agastum was 25 days. The flowering peak time of R. irroratum was 5 days earlier than that of R. agastum, which in turn was 5 days earlier than that of R. delavayi.
