摘　　要：红檵木是重庆常见的园林绿化植物,常用于道路两边绿化、校园绿化和公园绿化等。对重庆市主城区3种不同生境类型下19个样地的红檵木进行实地调查,研究不同生境类型和不同园林修剪形式对红檵木春季物候的影响。结果表明,叶平均物候期与花平均物候期显著正相关,展叶持续时间与开花持续时间不相关;公园的红檵木展叶及开花时间显著晚于道路和校园的,展叶速率最快,展叶持续时间最长;道路的红檵木开花持续时间最长。开花速率方面3种生境差异不大,自然状态的红檵木花期较早且开花持续时间更长,花量更多,观赏效果更好。As one of the common landscaping plants in Chongqing, Loropetalum chinense var. rubrum was commonly used in the road, campus and park. This paper investigated Loropetalum chinense var. rubrum in 19 samples with three different habitats in Chongqing to study the influence of different habitats and pruning techniques on the spring phenophase. The results showed that the average phenophase of leaves was significantly positive correlated to the average phenophase of flowers while the sprouting leaves dura- tion was not associated with the flowering duration, that with the fastest leafing speed and the most lasting leafing time, the leafing and flowering time in park was significantly later than that in road and campus , that the flowering duration was longest in road, and that the flowering speed had little difference in three habitats but the flowering time was early and lasting in natural habitat where the flower quantity was more and the ornamental effect was better.
