摘要
通过对5年生15个杨树无性系为材料的树高、胸径、材积及木材的纤维长度、纤维宽度、纤维的长宽比及木材的基本密度等的对比分析,结果表明:15个杨树无性系的木材平均纤维长度为0.773～1.111mm,纤维长宽比在34.5～46.0之间,基本密度在0.291～0.369g/cm3之间,壁腔比在0.26～0.39之间。综合评价认为592、107、187、303、2025、725、108、69、皖林2、皖林1等10个优良无性系可作为营造纸浆林的品种,符合造纸原料的要求。
Data was collected from 15 Populus spp. clones of 5-year-old. Height, DBH, individual stem volume, fiber length, fiber width, ratio of fiber length to width and wood basic density have been contrasted and analyzed. The results showed that： The average fiber length and the ratio of fiber length to width stands of 15 poplar varieties were 0.773-1.11 lmm and 34.5-46.0. The wood basic density and the ratio of fiber wall to fiber cavity stands were 0.291-0.369 g/cm3,0.26-0.39. Through comprehensive evaluation, such as 592 , 107,187,303, 2025,725.108,69,wanlin2 ,wanlinl could be considered as the first choice polar varieties for the stands of Pulp-forest cultivation.
