Abstract
In order to enrich and promote the varieties of colored-leaf trees for greening in northern Hebei,and the growth performance of colorful trees introduced in northern Hebei,the growth per-formance of the five colorful trees introduced in the experimental demonstration base of Longtoushan Breeding Farm of the state-owned forest farm of Mulan Weichang in Hebei Province was analyzed.The results showed that:(1)the average survival rate of the five color trees was 83.8％,and the preservation rate was 81.2％,at a high level;(2)the five color trees can achieve complete phenologi-cal display and normal growth in the growth year;(3)the duration and regularity of discoloration of the five color trees are different,and the ornamental period is longer;(4)among the five color trees,Ulmus pumila var.chinensis,Prunus mume var.pekinensis and Prunus rubra performed well in stress-resistance,and the management costs of the golden leaf wax and Euonymus japonicus are rel-atively high.关键词
