木兰科植物引种适应研究及其园林景观评价

A Study on Introduction and Adaptation of Magnoliaceae Plants and its Landscape Evaluation

本文对引种赣州市区、郊区的12种木兰科植物进行低温、高温干旱的露地调查及其景观评价,研究结果表明:华盖木(Manglietiastrum sinicum)、凹叶厚朴(Magnolia biloba)、观光木(Tsoongiodendron odorum)、云南拟单性木兰(Parakmeria yunnanensis)耐当地低温气候,景观评价等级高,且对高温伏旱的适应性较好,适合作为当地优选开发树种;二乔玉兰(Magnolia×soulangeana)、乐昌含笑(Michelia chapensis)、金叶含笑(Michelia foveolata)、深山含笑(Michelia maudiae)、醉香含笑(Michelia macclure)适应性较广,可以在赣州市区、郊区被较广泛地常规栽植;引种乐东拟单性木兰(Parakmeria lotungensis),需在其幼龄期采取一定的遮荫和灌溉的保湿降温措施;毛桃木莲(Magnolia kwangtungensis)和乳源木莲(Manglietia yuyuanensis)不适当地引种。

In this paper,12 species of Magnoliaceae were introduced into the urban and sub-urban areas of Ganzhou city.We conducted open-field surveys of their resistance to low temperature and high temperature and drought,and conducted landscape evaluation of these introduced plants.The results showed that 4 species of Manglietiastrum sinicum,Magnolia biloba,Tsoongiodendron odorum and Parakmeria yunnanensis,which were resistant to the local low-temperature climate,and had good adaptability to high temperature and drought,and gained landscape evaluation at high level,are listed as the preferred species;5 species of Magnolia×soulangeana,Michelia chapensis,Michelia foveolata,Michelia maudiae,Michelia macclure are widely suitable for routine planting in the urban and sub-urban areas of Ganzhou city;while introducing Parakmeria lotungensis,which needs to be taken certain measures of shading,cooling and moisturizing at its young age;but 2 species of Magnolia kwangtungensis and Manglietia yuyuanensis were not suitable for planting.
