| 摘 要： | 调查了经历乐昌市2020年12月—2021年1月低温天气的园林植物的受冻害、需处理和恢复的情况，记录到受冻害的园林植物有124种（含杂交种、变型和园艺品种），具有受冻害种类较多、外来植物受冻害比例高和同种植物受冻害程度因地或苗而异的特点。受冻害的主要原因除了长时间的低温天气外，还有苗木栽培时间短、引种不科学、管理粗放等。建议遵循适地适树原则，科学选择植物种类，区别选择南北两地种类；尽量使用本地苗圃培育的苗木，少用外来苗木；加强人工管护和灾后处理；提前炼苗。

| Abstract: | This paper investigated the situation of freeze injury, need to be treated and recovery of landscape plants experiencing the low-temperature weather from December 2020 to January 2021 in Lechang City and recorded 124 species(including hybrids, varieties and cultivars) of landscape plants suffered from freeze injury, characterized by more species of freeze injury, a high proportion of exotic plants suffered from freeze injury, and the degree of freeze injury of the same species varying from place to place or from seedling to seedling. The leading cause of freeze injury to landscape plants, in addition to a long period of low-temperature weather, are seedlings cultivated for a short period of time, unscientific introduction, sloppy management, and so on. It is recommended to follow the principle of right place and suitable trees, select plant species scientifically and differentiate between species from the north and the south; try to use seedlings cultivated in local nurseries and use fewer exotic seedlings; strengthen manual care and post-disaster treatment; and refine seedlings in advance. |
