摘要
通过对张家口坝上地区不同海拔高度樟子松苗木生长状况的研究,得出随着海拔高度的升高,樟子松苗木的高生长、根茎生长受到抑制,冻伤冻死几率增加,是制约张家口坝上地区樟子松引种成功与否的一个主导因子。
Based on the research on the growth situation ofPinus sylvestris var. mongolica Litv. at different altitude in Bashang district, Zhangjiakou, the results show that with the altitude＇s rising, the growth of height and rootstock of Pinus sylvestris var. mongolica Litv. is restricted and the cold mortality increase. This is a main leading factor to restrict the introduction of Pinus sylvestris var. mongolica Litv. in Bashang district, Zhangjiakou.
