摘　　要：海东市随着造林范围扩大、造林林种增加,造林树种单纯的矛盾日益突出。自2013年以来,先后从国内20个省、市(区)购买引进树种85种,并逐块栽植进行了全面的引种试验工作。结果表明:生长良好的有23个树种,生长正常的有24个树种,生长衰弱引种不成功的有38个树种。得出了在引进的85个树种中有47个树种是可以引种的,这些树种的引种成功,丰富了海东市原有的造林树种,为林业造林树种的引种选择提供了参考。With the development of construction,the scope of afforestation has expanded,and the number of afforestation species has increased.The contradiction of simple afforestation tree species has become increasingly prominent.Since 2013,85 introduced species trees from 20 provinces and cities(districts)in China are purchased and a comprehensive introduction experiment is conducted by planting them one by one.The results showed that there were 23 tree species with good growth,24 tree species with normal growth,and 38 tree species with weak growth that were not successfully introduced.It was found that out of the 85 tree species introduced,47 tree species could be introduced.The successful introduction of these tree species enriched the existing afforestation tree species in Haidong City and provided a basis for the introduction and selection of forestry afforestation tree species.
