摘要
分析了1998年引种的10个三倍体毛白杨系号在白银地区造林的生长适应性。结果表明:在同一立地类型和同等抚育条件下,A129、A128、B330、A125、B1008、BT85、A122等7个无性系杂种三倍体毛白杨幼林在白银地区速生、抗寒、耐盐碱、抗黄斑星天牛,对叶锈病、褐斑病和煤污病基本免疫,在白银市表现出较强的适应性和抗逆性,生长量显著高于普通毛白杨、群众杨、新疆杨;由于其速生性使黄斑星天牛不能完成生活史而不至于造成危害;在速生用材林、专用纸浆林、农田防护林和公路绿化等方面大力推广具有良好的发展前景。
Based on the analysis on growth adaptability of 10 varieties of triploid Populus tomentosa introduced in Baiyin district in1998, the results showed that : under the same site and management measures, its infancy forest of 7 clonal crossbreeds of A129, A128, B330, A125, B1008, BT85 and A122 grow fast and resist to cold, salinity and alkalinity and Anoplophora nobilis, and are almost immune to leafrust disease, brown patch disease and coal blotlike disease and their growth increment are remarkably higher than that of Populus tomentosa, Populus×'Popularis', Populus alba var pyramedalis, which indicate the stronger adaptability of triploid Populus tomentosa in Baiyin district; their fast growth make Anoplophora nobilis unable finish its life span and so it can not damage these trees; the 7 varieties will be promising in extantion of wood forest with fast growth, specialused paper pulp forest ,agricultural protection forest and afforestation of roadway
