四种槭树科植物在银川市的引种生长表现

Preliminary analysis on the growth performance of four Aceraceae plants introduced in Yinchuan city

为了解和掌握槭树科植物在银川市的引种生长表现,引种栽培金贵黄枫、青龙、鸡爪槭、红火树-珊瑚阁4种槭树科植物,经过1年的生长,观测统计其生长状况、观赏性、越冬和越夏表现以及成活率,对其引种生长表现进行初步分析评价。结果表明:4种槭树科植物在银川的生长表现存在差异,鸡爪槭和红火树-珊瑚阁越冬越夏能力强,金贵黄枫和青龙越冬越夏能力较弱;红火树-珊瑚阁成活率最高,达到了86.6%,其次是鸡爪槭,成活率为66.7%,青龙和金贵黄枫成活率最低,为33.3%;观赏性方面,鸡爪槭、红火树-珊瑚阁和青龙表现良好,金贵黄枫次之。综合分析认为,红火树-珊瑚阁和鸡爪槭在银川地区的生长状况较好,采取适当保护措施可使其正常生长;青龙和金贵黄枫在银川地区的生长状况较差,有待驯化与研究。

In order to understand and grasp the introduction and growth performance of four species of Aceraceae in Yinchuan,Ningxia,after one year of growth,the introduction and growth performance of the four aspects of growth status,ornamental value,winter and summer performance and survival rate were analyzed and evaluated.The results showed that the growth performance of the four Aceraceae plants in Yinchuan was different:Acer acuminatus and red fire tree had strong ability of overwintering and oversummer,but Jingui and Qinglong had poor ability of overwintering and over summer.The survival rate was the highest(86.6%),followed by Acer chinense(66.7%),Qinglong(33.3%)and Jingui(33.3%).Appreciation of Acer chickenacer,red fire tree and green dragon performed well,Jin Gui second.Comprehensive analysis:the growth of Acer saccharinum‘Skinneri’and Acer palmatum were better,and could grow normally with protection measures in Yinchuan area.The growth of Qinglong and Jingui in Yinchuan is poor and needs to be domesticated and studied.
