摘　　要：以东丰试验点的13年生大青杨无性系评比林为试验材料,通过生长指标、物候期、干型及抗性等调查和综合分析,初步选择出L18和N8两个无性系为适宜试验地及毗邻地区生长的优良品系。结果表明,L18和N8两个无性系树干通直,抗性较强,无病虫危害,平均树高生长量分别超过参试无性系平均值16.9%和16.5%,平均胸径生长量分别超过参试无性系平均值37.9%和40.2%。The 13-year-old Populus ussuriensis clone clones at Dongfeng test site were used as test materials. Through investigation and comprehensive analysis of growth indicators, phenophase, dry type and resistance, two clones L18 and N8 were initially selected as Excellent strains suitable for growth in test plots and adjacent areas. The results showed that the trunks of the two clones L18 and N8 were straight, with strong resistance and no harm to pests and diseases. The average tree height growth exceeded the averages of the tested clones by 16.9% and 16.5%, respectively, and the average DBH growth exceeded the parameters. Test clones averaged 37.9% and 40.2%.
