【摘要】 本论文以安徽省城市园林中木兰科树种的引种和应用为研究内容,通过对安徽省主要城市园林绿地的调查,从木兰科植物资源、地理分布、生物学和生态学特性等方面,对安徽省木兰科植物进行了园林观赏特性的研究,调查了我省城市园林中木兰科树种资源种类、抗寒性以及在园林中的表现,对丰富我省园林植物种类和木兰科植物景观具有理论指导和现实意义。1.安徽省植物资源中可供园林绿化的观赏植物资源浩繁,木兰科植物资源较为丰富,通过资源调查,将《安徽植物志》记载的记载的4属,11种,1亚种,扩展到了6属,34种(含1变种、1亚种和1杂交种)。2.通过对合肥、芜湖、马鞍山城市园林绿地调查,得知目前在园林上运用的仅有荷花玉兰、紫玉兰、白玉兰、含笑等少数树种,其他优良园林树种仍隐居山野,或已引种驯化成功但仍未广泛应用。3.对安徽省林科院园林苗圃、合肥植物园、黄山市林科所引种栽培的木兰科植物的生长情况、观赏价值、生物学特性及园林绿化效果的调查结果表明,木兰科植物由于其姿态优美、枝繁叶茂、花色艳丽而芳香、果形奇特的观赏特性,安徽省已从各地引种栽培的木兰科植物中筛选出了一批生长良好,具有很大的园林应用发展前景的树种。4.通过对合肥市新引进的6种常绿木兰科的抗寒性进行了初步研究,通过在越冬期间各个树种外部性状的表现和抗冻指数的分析,综合评价出了6个树种的抗寒能力,耐寒性由强到弱依次为乐东拟单性木兰＞深山含笑＞乐昌含笑＞阔瓣含笑＞金叶含笑＞红花木莲,这将为安徽省应用这6个树种提供参考。5.对木兰科在安徽省3个城市中的应用和不同树种在园林中的应用均进行了比较和实例分析,并对木兰科植物在安徽省城市园林中的应用提出了几点建议。更多还原

【Abstract】 The Introducing cultivation and application of Magnolia family trees in gardens of Anhui Province were studied.Based on the investigation on garden green land in the main cities of Anhui province,this study analyzed the natural resources, geographical distribution,biological,ecological ornamental characteristics of Magnolia family plant in Anhui province.Studied on the resource typies,cold resistance and performances of Magnolia family trees in gardens of Anhui Province.It provides with theoretical instruction and practical significance for enriching the varieties of gardens plants and scene of Magnolia family plants.1.A large amount of ornamental plant among the plant resources in Anhui Province could be plant for gardens and green.There were many kids of Magnolia family plants in this region.According to the investigation on plant resources,expanding the Magnolia family plants from four genera,eleven species,one subspecies recoreded in the "Anhui Plants Chronicle" to six genera,thirty four species(including one mutation,one subspecies and one hybrid species).The results made to know the real situation of Magnolia family plants in Anhui province.2.According to the investigation on gardens and green lands in Hefei,Wuhu and Maanshan cities,there were only a small part of Magnolia family trees in the cities area,such as M.grandiflora、M.liliflora、M.denudate、Michelia figo etc.Most of the other good types of trees were not cultivate in urban,but growed in mountain or not wide-ranging used after taming.3.We investigated the effection of Magnolia family plants in cities.The results indicated that the Magnolia family plants showed up the characteristics of beautiful postures,thick foliage,colourful flowers,fragrant smell and peculiar fruit shape.There were already planted many kinds of Magnolia family plants after select the tree species which growed well and transplanted extensively in Anhui.4.The characteristic of the cold resistance was studied on six evergreen Magnolia family plants which is introduced recently in Hefei by observing the exterior appearances,calculating and analyse the index of the cold resistance.Among them,the strong cold resistant tree species was Parakmeria lotungensis,then followed by Michelia maudiae,M.chapensis,M.platypetala,M.foveolata and Manglietia insignis in ture.It will provide a consult for application of the six kind of trees in Anhui Province.5.This paper also studied the application foreground of Magnolia family plants for gardens through comparing different tree species of Magnolia.The author also ummarized the introducing taming of Magnolia family plant in Anhui province and provided some suggestions.更多还原
