【摘要】:2016年1月昆明市發(fā)生了32年一遇的強(qiáng)低溫天氣,為檢測昆明市主要園林植物的抗凍能力,對園林植物種類較為豐富的呈貢區(qū)進(jìn)行了凍害調(diào)查。結(jié)果表明:凍害等級達(dá)到"嚴(yán)重"和"極嚴(yán)重"的園林植物有56種,全部為外來植物;凍害程度與植物的原產(chǎn)地、生物學(xué)特性、生長勢、生境等因素有關(guān);凍害對喬木的園林景觀及生態(tài)效益影響較大,尤其是常綠行道樹。分析認(rèn)為,昆明市應(yīng)減少外來熱帶植物的栽植,今后在引進(jìn)外來植物時應(yīng)加強(qiáng)對其低溫限制因子的考慮。研究可為云貴高原的城鄉(xiāng)園林建設(shè)、園林植物規(guī)劃和園林苗木培育提供參考數(shù)據(jù)。
[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.
