对顺义、菏泽和廊坊三个地区不同树龄欧美杨107的化学成分、纤维形态以及制浆性能进行对比研究。结果表明,顺义地区的壤土四年生欧美杨107的木素含量最低为21.91%,综纤维素含量高达86.24%,卡伯值和K/Y值均最低,分别为14.5和0.279,粗浆得率最高为52.0%,黏度适中1186mL/g,制浆性能优于其它欧美杨107试样。
The chemical composition, fiber morphology and pulping properties of P. yangshuang 107 with different ages in Shunyi, Heze and Langfang regions were compared. The results showed that the lowest lignin content was 21.91%, the content of holocellulose was 86.24%, and the lowest Kappa number and K / Y value were 14.5 and 0.279 respectively. Up to 52.0%, viscosity 1186mL / g, pulping performance better than other European and American Yang 107 samples.
