| 摘 要： | 根据云杉在南五台，宁长，长青三地试验的数据，对１－５年生苗木和幼森生长性状进行了试验分析，结果表明：不同种间高生长，发芽率，保存率存在极显著差异，这些苗期和幼林期的性状差异与地理经，纬度相关不紧密。初步选择出生良好，稳定性强的７，９，５，１号种。

| Abstract: | Growing characters of 1 to 5-year-old seedlings and their growth were a.nalyzed from the data collected from experimental plots in three areas of Wutai,Ningdong and Changqing. The results show that there exist significant differences among species in height growth, germination rate and survival rate,and the character variation is not closely related with geographic longitude and latitude. The species of No. 7, 9, 5,and I with good growth and stable characters have been tentatively selected out. |
