中文摘要	在甘肃省干旱半干旱区引种4年生云杉属7个植物,对其抗寒性、抗旱性、耐盐碱性及生长性状进行研究。结果表明:在试验区7个云杉属树种抗寒性表现为川西云杉=红皮云杉>白扦=粗枝云杉=恩氏云杉=蓝云杉>黑云杉;白扦、恩氏云杉抗旱性较差,其它云杉属树种表现较好;恩氏云杉抗盐碱性较差,而其它云杉属的树种表现出较好的抗盐碱特性。7个云杉属树种引种后保苗率为红皮云杉>川西云杉>粗枝云杉 >白扦>蓝云杉>恩氏云杉>黑云杉。7个云杉属树种树高、当年新梢生长量和冠幅的变异系数较大,各性状在种间差异极显著。对7个云杉属树种运用性状综合评价方法进行评价,初步筛选出在甘肃省干旱半干旱区具有较强适应性和生长潜力的云杉种为川西云杉和红皮云杉。
英文摘要	Seven species of 4-year-old Picea were introduced in arid and semi-arid regions of in Gansu Province to study their cold-tolerance,drought resistance,salt-salinity tolerance and growth traits. The results showed that the cold resistance of 7 species of Picea in the experimental area was as follows: Picea balfouriana = Picea koraiensis > Picea asperata = Picea meyeri = Picea pungenGlauca Globosa’= Picea engelmanii > Picea mariana; Picea meyeri and Picea engelmanii had poor drought resistance and other spruce plants performed well. Picea engelmanii had poor salt and alkalinity,while other Picea species showed better resistance to salinity. The conservation rates of the seven species of Picea after introduction were as follows: Picea koraiensis > Picea balfouriana > Picea asperata > Picea meyeri > Picea pungenGlauca Globosa’> Picea engelmanii > Picea mariana. The coefficient of variation of tree height,shoot growth,and crown width of the seven species of Picea were relatively large. The differences among the traits were extremely significant among the species. A comprehensive evaluation method for traits of seven species of Picea was used to evaluate the spruce species. The Picea balfouriana and Picea koraiensis were selected as the spruce species with strong adaptability and growth potential in the arid and semi-arid regions of Gansu Province.
