摘要:
2016 年1 月23-25 日,浙江省杭州市连续3 d 最低温-8 ~ -9℃,许多园林植物遭受不同程度冻害。于2016年2 月上中旬、2016 年4 月下旬至5 月下旬对杭州植物园、西湖景区公园、部分街道绿化及住宅小区园林植物进行调查,并对其受冻害情况及其冻后养护恢复情况进行调查分析。结果表明,共有19 科34 属41 种园林植物遭受不同程度的冻害,其中约83%为引种植物;66%的植物冻害等级为轻度或中度,不需人为干预或适度修剪就能恢复正常生长;27%的植物冻害等级为重度,长势明显趋弱;7%的植物出现受冻死亡的现象。建议在森林城市建设中,植物的引种遵循科学规律,重视驯化,尽量选用乡土植物与外来植物相搭配的配置方式,加强日常管护,降低低温逆境胁迫对园林植物的影响。
Abstract:
From January 23rd to 25th in 2016, Hangzhou of Zhejiang province experienced three consecutive days ofthe lowest temperature -8-9℃,and many garden plants were suffered varying degrees of cold injuries. Investigations were carried out on garden plants at Hangzhou BotanicalGarden, parks in the West Lake scenic area, part of streets and residential areas in middle February 2016 and late April to late May of the same year.The results showed that 41 species of 34 genera and 19 families were injured by the cold weather, among them, 83% were introduced species. About66% species were injured slight or moderate, and recovered by pruning or even without any operation. 27% species were severely damaged, and theirgrowth turned weaker obviously.7% species were died. Suggestions were put forward for better growth of garden plants such as less introduction,more domestication and much more local species for distribution and better management.
