摘要
为探清紫金县乡村绿化美化引入的11种景观树种露地栽植抗寒适应性,进行了连续3个越冬期的观测调查。调查结果表明,11种景观树种的抗寒性能力表现存在较大差异,并根据抗寒平均指数划分为4个抗寒等级。其中,6种达到较强以上抗寒等级的景观树种,在无保护措施下露地栽植可在紫金地区安全越冬,适宜引种推广。
To explore the cold resistance adaptability of 11 types of landscape tree species introduced into Zijin area for beautifying and greening purpose under open field cultivation, A survey was conducted for 3 successive over-wintering periods. The results showed that there is significant difference in cold resistance adaptability among 11 kinds of landscape tree species. And 4 cold resistance grades are divided according to average cold resistance index of those 11 types of landscape tree species.
