摘　　要：为了找出不同扦插密度对北京杨扦插苗生长的影响,进行了北京杨硬枝扦插的对比分析试验,采用10 cm×10 cm、20 cm×20 cm、30 cm×30 cm、40 cm×40 cm、50 cm×50 cm不同密度处理,分析比较了扦插生长的最适密度。结果表明,30 cm×30 cm扦插密度处理的北京杨生根率、生根长度及新生枝条长度都好于其他扦插密度处理。The effects of planting density on growth of cuttage seedlings of Populus beijingensis W.Y.Hsu were studied by comparative analysis test in which the cuttage seedlings were planted at density of 10 cm×10 cm,20 cm×20 cm,30 cm×30 cm,40 cm×40 cm and 50 cm×50 cm.The results showed that the optimal density of cuttage seedling was 30 cm×30 cm as the rooting rate,as root length and length of new branches of seedlings were better than those of the other planting densities.
