摘要
云杉是青海省县主要的天然林资源,也是荒山造林和城镇绿化的优良树种。随着林业"三大"工程在我省的实施,对种苗的需求量日益增大,我省地处高海拔区,研究高海拔区云杉的育苗技术,对加快我省的生态建设,促进经济可持续发展有着深远意义。
Picea is not only major natural forest resources in Qinghai,but also fine tree species of afforestation and urban greening.With the implementation of ＂three＂ project of forestry in our province,the demand for seedlings is increasing.Since our province is located in high altitude area,studying seedling cultivation of picea of high altitude area has far-reaching significance to speed up ecological construction of Qinghai province and promote sustainable economic development.
