3个彩叶豆梨品种在银川地区的引种栽培试验

Introduction and Cultivation Experiment of Three Varieties of Color-Leaf Gallery Pear in Yinchuan

为丰富银川地区园林观赏树种,特别是彩叶树种,笔者在宁夏银川地区开展3个彩叶豆梨优良品种(“首都”“贵族”“克利夫兰”)引种栽培试验,对其生物学特性、物候期、植株生长情况进行了研究。结果表明:这3个品种均具有树形紧凑、枝叶丰满、发芽率、保存率、秋季叶色鲜红或橙红等特点,有较好的观赏价值。其中,“首都”的平均叶生长期和平均红叶期最长,发芽率和保存率最高,植株生长情况整体优于“贵族”和“克利夫兰”,可用于公园、小区、街头景点绿化美化,相较于“贵族”和“克利夫兰”更适合在银川地区栽植。

In order to enrich landscape tree species especially color-leaf varieties,three excellent varieties of color-leaf gallery pear(Capital,Nobility and Cleveland)were introduced and cultivated in Yinchuan,Ningxia.The biological characteristics,phonological period,germination rate and survival rate and plant growth were studied.The results showed that these three varieties have compact tree shape,abundant branches,and bright red or orange-red leaves in autumn and etc..They all have good ornamental values and good adaptability,and among them,Capital has the longest average leaf growth period and red leaf period,germination rate and survival rate,and generally,it has the best plant growth.Therefore,Capital is more suitable to be used in parks,communities and streets in Yinchuan.
