介绍了复叶槭变种——金叶复叶槭(Acer negundo‘Aurea’)在陇东地区的引种表现,通过引种栽培及繁育试验,分析了它的生物学特性、生态适应性和抗性,对比总结出最佳育苗技术。结果显示:该树种叶色多变,观赏期长,抗寒等级为二级以上,且长势健壮,少有病虫害,可作为优良彩叶树种大力推广。通过繁育试验对比,带木质芽接成活率在95%以上,建议在今后苗木繁育中应用。
The introduction of Acer negundo’Aurea ’introduced in Longdong region was introduced. Its biological characteristics, ecological adaptability and resistance were analyzed by introducing cultivation and breeding test. Contrast summed up the best breeding technology. The results showed that: the tree species varied leaf color, long ornamental period, cold resistance grade two or more, and the growth of robust, few pests and diseases, can be used as a good color leaf tree species to promote. Through the comparison of breeding test, with wood budding survival rate of 95% or more, it is recommended in the future seedling breeding applications.
