摘　　要：以引进的欧洲云杉和乡土种青海云杉、粗枝云杉种子5年生苗的苗高、地径、当年新梢生长量、分枝数、总芽数及二次抽梢等6个生长指标,进行了差异显著性分析,结果表明,欧洲云杉较乡土种在苗期即具有显著的生长优势,在适生区选择欧洲云杉育苗,即可解决云杉育苗周期长的问题。Through analysis of the significance difference for six growth index including five-year-old seedling height ,basal diameter, cmTent-year new shoot increment, branch number, total buds and secondary sprout of introduced Picea abies ,native species of Picea crassifolia and Picea asperata, the results indicated that Picea abies has distinct growth superiority compared with native species of Picea crassifolia at the seedling stage, therefore, seedling cultivation of Picea abie in the suitable distribution areas which can solve the problem of long nursery period of Picea abies.
