| 摘 要： | 2009年冬季低温对北京市的园林植物造成了严重的伤害。于2010年春季对部分苗圃、公园、绿地等的植物进行了冻害调查,并按照冻害程度进行了分级。结果如下:(1)受害最为严重的植物有:石榴、紫薇、大叶黄杨、丝兰,冻害等级达到了5、6级。竹子的冻害等级为5级。雪松达到了4级;(2)一些冻害等级为5的灌木,如梾木、八仙花、山梅花、木槿等,进行及时的修剪,当年仍能开花,不影响观赏效果。(3)海棠、丁香、玉兰、荚迷、白蜡等的大部分品种表现出较强抗寒性,适合北京地区栽植;(4)‘绿宝石’黄杨、‘冬美’黄杨、‘约翰’黄杨、‘福克纳’黄杨、‘绿丝绒’黄杨等黄杨新品种,抗寒等级达到1级,成功抵御了冻害。此次园林植物冻害的调查和分析,为今后北京地区的植物引种、园林养护与应用提供了参考。
