摘要 为了筛选耐寒树种,进而为胶东地区园林绿化常绿阔叶树种的选择提供依据,对23种胶东地区引进的常绿阔叶树种越冬冻害情况进行了比较研究。结果表明:红叶石楠、北海道黄杨、小叶扶芳藤、常春藤、扶芳藤、凤尾兰、枸骨、枇杷和石楠在胶东地区可安全越冬,不受冻害影响或受冻害影响很小,适于在该地生长;马醉木、南天竹、阔叶十大功劳、高山杜鹃、广玉兰、海桐、火棘、龟甲冬青、山茶和桂花约1/3的叶片越冬受冻失绿,部分枝条枯死,能够适应胶东地区的生长环境,可进行推广应用;十大功劳、法国冬青、细圆齿火棘和香樟越冬表现较差,抗寒能力弱,在引种过程中,要有严密的保护措施,以防受到冻害。枇杷、海桐、火棘和南天竹在市郊或者海滨无保护的环境中受冻害严重,但在管理状况较好的绿地环境中能够安全越冬。 In order to screen cold resistance species and provide a practical reference guide for introducing evergreen broad-leaved tree species in eastern Shandong,23 species of evergreen broad-leaved trees'freezing injury condition overwintering had been investigated.The results showed that,the plants of Photinia serrulata,Euonymus japonicus Thunb.,Euonymus fortunei var.radicans,Hedera nepalensis var.sinensis,Euonymus fortunei(Turcz.)Hand.-Maza.,Yucca gloriosa L.,Ilex crenata Lindl.,Eriobotryajaponica(Thunb.)Lindl.and Photinia serrulata Lindl.could overwinter safely,suffering less freezing injury and fitting for the growing environment.Plants of Nandina domestica Thunb.,Mnonia bealei(Fort.)Carr.,Rhododendron lapponicum(L.)Wahl.,Magnolia grandiflora L.,Piittosporum bobira(Thunb.),Pyracantha fortuneana(Maxim.)Li,Ilex crenata cv.Convexa,Aamellia japonica Linn.and Osmanthus fragrans(Thunb.)Lour.could adapt to the growing condition in eastern Shandong,having part of branches withered with one third of leaves chlorotic.Plants of Folium Mahoniae Bealei,Viburnum odoratissimum Ker.,Pyracantha crenulata(D.Don)Roem.and Cinnamomum comphora(L.)Prsel.had weak ability in overwintering.A series of measures should be took to protect them from freezing injury.Plants of E.japonica,P.bobira,N.domesticaand P.fortuneanasuffered from freezing injury hardly in suburb or coast with no protection.
