摘要
本文分析了2001年作为纸浆林发展引种的10个三倍体毛白杨系号在石羊河流域造林的生长适应性。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石羊河流域速生、抗寒、耐盐碱、抗黄斑星天牛,在石羊河流域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;在专用纸浆林方面大力推广具有良好的发展前景。
The paper has analyzed the growth adaptability of 10 varieties of triploid Populus tomentosa of pulpwood forest afforested in Shiyanghe in 2001. The result indicated： under the conditions of the same site types and the same management measures, the tender forests of 7 varieties includingA129, A128, B330, A125,B1008,BT85, A122 represented good adaptability and resistance such as rapid growth, cold resistance, salinity ＆. alkalinity tolerance and anti-Anoplophora nobilis in Shiyanghe watershed. The growth increment of these varieties were significantly higher than that of P. tornentosa, P. X ＇Popularis＇ , P. alba var. pyrarnidalis; Just with this rapid growth characteristics, it made Anoplophora nobilis could not complete its life span and the damages could not occur, too. So it will has good developmental prospect in special pulpwood forest.
