北美樱桃核桧于1987 年引入呼和浩特市树木园,经10a 的引种驯化与3a的无性繁殖试验,证明该树种比当地其他柏类树种更耐旱、耐寒,无病虫害,生长旺盛。经分析北美樱桃核桧生长规律吻合于指数增长方程。10 年生平均树高2 .5 m ,最高达3 .2 m ,针叶呈淡蓝灰绿色,冠形优美,为温带半干旱地区庭院、街道、公园等地绿化的优良新树种。本文着重报道了其生态习性、引种驯化与栽培管理及扦插繁殖技术。
North American cherry cypress introduced to the tree garden in Hohhot in 1987, after 10 years of introduction and acclimation and 3a vegetative propagation test, the species proved to be more drought than other cypress species, cold, no pests and diseases, vigorous growth. Analysis of North American cherry nuclear cypress growth consistent with the law of exponential growth equation. The 10-year-old tree has an average height of 2.5 m and a maximum of 3.2 m.
