摘要
采用样方法研究2008年春季冰雪灾害对株洲市常绿木本园林植物的影响。结果表明:株洲市常绿木本园林植物受严重灾害后表现为雪折、雪倒及器官冻害;雪折、雪倒现象较严重的植物为樟树、毛竹、杉木及马尾松;冻害现象最严重的大多为近几年从南亚热带地区引进的树种,这些树种需2～4年才能恢复正常形态;本地传统绿化植物中受冻害的种类在5月下旬均发出新枝叶,恢复正常生长。冰雪灾害对园林植物的极端危害是可以预防的:在园林植物引种过程中应遵循科学地引种驯化步骤,建立健全的引种法规;依据立地类型选用园林绿化植物,还须强化园艺技术(特别是防寒防冻和修剪整型)以及营造混交林、防护林等栽培管理措施。
Snow disasters in the early spring of 2008 to the garden evergreen woody plants in Zhuzhou was investigated with the quadrat method.The results showed that the ornamental plants in Zhuzhou,Hunan Province were seriously damaged by the heavy snow squall.The injured symptoms of plants were characterized by snow broken,snow inverted,and plants organs frozen.Cinnamomum camphora,Phyllostachys edulis,Cunninghamia lanceolata,and Pinus massoniana were more injuried by snow broken and snow inverted.The most injuried species were those introducted from south subtropical regions in recently years.Most of them died,and some survival ones need 2～4 years to recover.All native traditional plants hurt by the freezing flushed new leaves in late May and recovered to normal growth.The authos believe that it is possible to prevent from snow disasters.Some measures must be done for that.Scientific principle in introducing of exotic species must be obeyed.Sound rules for introducting exotic tree species must be carried out.Adaptable trees would be planted in adaptable sites.Garden plants are chosen according to forest site classification.The horticultural technology must be improved（for example coldproofing and frostproofing measures,pruning and sculpting）.Cultivation and management measures such as planting mixed forests and shelterbelts can prevent snow disasters from injuring trees.
