摘　　要：为解决广州市部分桥梁绿化三角梅枝条老化、植株空脚、冠幅过大等问题,调节植株通风透光,保证桥梁绿化整体景观效果,广州市林业和园林科学研究院于2020年3—4月对广州市主要干道的桥梁三角梅首次开展了中度和重度修剪工作。文章对此次修剪后的相关数据进行了总结,并与未修剪的桥梁进行对比,探究其中(重)度修剪方式对桥梁绿化三角梅景观效果的影响。结果表明:经过修剪复壮后的桥梁三角梅花期相对于未修剪的桥梁花期延迟15d左右,植株抗寒性能及整体景观效果也明显优于修剪前,说明重(中)度修剪能够调控三角梅花期,并提高其耐寒性,该结果对桥梁绿化养护有较强的指导性。This article discusses the effects of the aging of Bougainvillea branches,empty stems,and excessive crown width in bridge greening in Guangzhou city.To address these issues and ensure the overall landscape effect of bridge greening,the Guangzhou Institute of Forestry and Landscape Architecture conducted moderate and severe pruning on Bougainvillea planted on prime thoroughfares in Guangzhou from March to April 2020.In this study,data from unpruned and pruned bridges were collected for comparison,and the atat included the flowering period and cold resistance.The results show that after pruning and rejuvenation,the flowering period of Bougainvillea on bridges is delayed by approximately 15 days compared with that on unpruned bridges,and the cold resistance and overall landscape effect of the plants are significantly better than those before pruning.These findings indicate that heavy(moderate)pruning can regulate the flowering period of Bougainvillea and im-prove its cold resistance,providing powerful guidance for bridge greening maintenance.
