引进 39个黑杨派新无性系 ,以I6 9杨和中林 4 6杨为对照 ,进行苗期试验和造林试验。分别在鲁西南、鲁南、胶东、鲁西北共营造区域化试验林 2 0片 ,并测定各无性系的生长性状、形质指标、木材材性以及抗干旱、耐盐、抗病虫等性状。经过多性状分析 ,选出L35、L32 3、L32 4、T6 6、T2 6、I10 2、L80 2、I10 7、中菏 1号等 9个综合性状优良的无性系 ,可作为优良品种在山东省推广应用 ,并提出它们的适生范围、培育目标及栽培技术要点。
39 black poplar clones were introduced. Seedlings and afforestation experiments were conducted with I6 9 Yang and Zhonglin 46 as control. A total of 20 regionalized experimental forests were established in Southwest Shandong, Lunan, Jiaodong and Northwest Shandong, and their growth traits, quality traits, wood properties and resistance to drought, salt, pest and disease were measured . Through the analysis of multi-traits, 9 elite clones with excellent comprehensive characters such as L35, L32 3, L32 4, T6 6, T2 6, I10 2, L80 2, I10 7 and Zhonghe 1 were selected and used as elite cultivars in Shandong Promote the application of the province, and put forward their scope of fitness, cultivation objectives and cultivation techniques.
