以北京市栽培的猥实实生苗为材料,在延吉市帽儿山植物园进行引种栽培试验,结果表明:在引种地猥实能够正常完成营养生长和生殖生长,并可实现天然更新,没有冻害和病虫害发生;植株平均高度为2.81m,最大树高可达3.8m,冠幅丰满,体量与原产地和次生引种地基本不存在差异,可在延吉盆地城乡园林绿化中推广应用。

A preliminary study was conducted on the introduction of Kolkwitzia amabilis from Beijing to Maoershan Botany Garden of Yanji city.The results showed that： the natural regeneration of K.amabilis could be achieved in the introduced area because the vegetative and reproductive growth of this species performs normally.There was no pest disease or winter injury.The average height was 2.81 m,and the tallest height was 3.8 m.The K.amabilis performed similarly in introduced area,original area and secondary introduction area.Therefore,K.amabilis could be widely used for landscape and garden greening in urban and rural region of Yanji Basin.
