西安市四种彩叶植物引种试验

Studies on Introduction and Cultivation of Four Color-leaf Plants in Xi'an area

在西安市长安区进行了加拿大红叶紫荆、紫叶锦带、金叶复叶槭、金叶白蜡等四种彩叶植物引进试验研究,结果为该四种植物在西安市均可安全越冬、越夏,生长正常,长势强健,观赏效果良好,其中金叶复叶槭早春展叶早、叶片观赏期最长,金叶白蜡展叶也较早、叶片观赏期也较长,紫叶锦带展叶最晚、叶片观赏期最短;四种彩叶植物值得在西安市园林绿化中推广应用。

Four color-leaved plants ——Cercis canadensis,Weigela Florida＇Foliiapurpureis＇,Acer negundo＇Aurea＇and Fraxinus chinensis Roxb,were introduced from Jiangxi province for planting test.The result showed that four plants all can safely go through winter and summer,performing well in growth and ornamentation.Acer negundo＇Aurea＇and Fraxinus chinensis Roxb can shoot leaves earlier and last long for ornamentation.Weigela Florida＇Foliiapurpureis＇ shoot leaves very late and last shorter period for ornamentation.
