甘肃高寒半干旱区园林绿化中金叶榆的配置模式
|
摘要
金叶榆是我国自主培育成功的彩叶植物新品种。为丰富高寒半干旱区生态城市建设树种资源,改变园林景观色彩单一、植物配置模式单调的局面,进一步提升城乡绿化景观的内涵层次,从宁夏林业科学研究所引进金叶榆,进行了区域栽培试验及示范推广,结果表明:该树种在高寒半干旱地区生长表现优良,抗寒耐旱,种苗繁殖容易,园林用途广泛,成活率在98%以上,景观效果极佳,是优良的黄色系彩叶树种;提出了该树种在城镇园林绿化中的5种配置模式,即模纹花坛配置模式、色篱配置模式、散植模式、列植模式、片植配置模式,以期增加高寒半干旱区彩叶树种资源,丰富园林景观色彩,为园林绿化建设带来更广阔的发展空间。
Ulmus pumila cv.Jinye is China's own successful cultivation variety of Coleus plants.To enrich plant species resources in ecological city construction in alpine-cold semiarid area,change the poor situation of landscape architecture with sigle color and monotonous plant configuration mode and to further enhance the level of urban and rural green landscape,Ulmus pumila cv.Jinye was introduced from Ningxia Institute of Forestry for regional cultivation experiment,demonstration and populization in Gansu.The results showed that the species in cold semiarid areas presented characteristics of good growth performance,cold and drought resistance,good seed breeding ability,and wide garden application.The survival rate was of over 98%,and the landscape effect was perfect.Therefore,it is an excellent yellow color species.Five configuration modes of this species in urban landscape application were proposed:carpet flower bed mode,colorful fence configuration mode,scattered planting mode,line-planting mode,and forest planting mode.These modes can increase the resources of species with colorful leaves in the alpine-cold semiarid area,enrich color diversity in landscape architecture,and promote the landscaping development.
