【摘要】：2016年1月昆明市发生了32年一遇的强低温天气,为检测昆明市主要园林植物的抗冻能力,对园林植物种类较为丰富的呈贡区进行了冻害调查。结果表明:冻害等级达到"严重"和"极严重"的园林植物有56种,全部为外来植物;冻害程度与植物的原产地、生物学特性、生长势、生境等因素有关;冻害对乔木的园林景观及生态效益影响较大,尤其是常绿行道树。分析认为,昆明市应减少外来热带植物的栽植,今后在引进外来植物时应加强对其低温限制因子的考虑。研究可为云贵高原的城乡园林建设、园林植物规划和园林苗木培育提供参考数据。
[Abstract]:In January 2016, a strong cold weather occurred in Kunming once in 32 years. In order to test the freezing resistance of main garden plants in Kunming, a freezing injury investigation was carried out in Chenggong District, where there are abundant species of garden plants. The results showed that there were 56 species of garden plants with "severe" and "extremely serious" degrees of freezing injury, all of which were exotic plants, and the degree of freezing injury was related to the origin, biological characteristics, growth potential and habitat of the plants. Freezing injury has a great influence on the landscape and ecological benefits of trees, especially evergreen street trees. It is concluded that the cultivation of exotic tropical plants should be reduced in Kunming, and the low temperature limiting factors should be taken into account when introducing exotic plants in the future. The study can provide reference data for urban and rural garden construction, garden plant planning and garden seedling cultivation in Yungui Plateau.
