云杉广泛分布于我省原始林区及次生林区的亚高山和河谷坡地。三个主要的种类:青海云杉(Picea crassifolia)、紫果云杉(P.purpurea)、青扦(P.wilsonii)都已成为我省林区主要的更新树种。云杉耐荫,喜欢大气湿润和凉爽的生境,由于它的种粒小,育苗技术要求高,历史上遗留下来的人工林很少。解放前及解放初期仅有小片用野生苗移植的造林地;1962年以后,我省多数林场基本上解决了云杉育苗的技术问 Spruce is widely distributed in the primeval and secondary forests in the province of subalpine and valley slopes. Three major species: Picea crassifolia, P. purpurea, P. wilsonii have become the major regeneration species in our province. Spruce shade, like moist and cool atmospheric habitat, due to its small size, high seedling technology requirements, the history of the plantation left behind few. Before liberation and the liberation of early only a small transplant with wild seedlings of afforestation land; after 1962, most of our province forest basically solved the technical problems of spruce seedlings
