以A5-13杨、A5-17杨等6个杨树种、品种(系)为试验材料,对基本密度、气干密度、干缩系数、纤维长度、纤维宽度及综纤维素含量进行了测定,结果表明:A5-13杨、A5-17杨属于木材密度中等的品系,基本密度均为0.36 g.cm-3,气干密度分别为0.43 g.cm-3、0.42 g.cm-3;体积干缩系数分别为0.37和0.35,小于大多数杨树种、品种(系),抗变形能力较强;木材纤维长度分别为1 175μm、1 230μm,超过大青杨7.5%和12.6%;综纤维素含量分别为84.3%、85.4%,是优良的制浆、造纸材。
The basic density, air-dry density, dry shrinkage coefficient, fiber length, fiber width and holocellulose content of six poplar species and varieties (lines) of A5-13 Yang and A5-17 Yang were tested. The results showed that: A5-13 Yang, A5-17 Yang belong to the medium wood density, the basic density is 0.36 g.cm-3, air dry density were 0.43 g.cm-3, 0.42 g.cm-3; Volume shrinkage coefficients were 0.37 and 0.35, respectively, which were less than those of most poplar species and varieties (lines). The wood fiber length was 1 175μm and 1 230μm, respectively, exceeding 7.5% and 12.6% of Populus euphratica. Cellulose content was 84.3%, 85.4%, is an excellent pulp and paper.
