| 摘要:以5~15年生米老排、黑格和大叶栎为研究对象，7年生尾巨桉为对照，通过对比分析不同树种和林龄样木的木材基本密度、纤维形态、制浆特性及造纸性能，综合评价了不同原料的制浆造纸适用性。结果表明，基于坐标综合评定法获得的3个速生阔叶树种纸张物理强度得分值（0.59~19.91）小于桉木（21.25），均为较优的制浆造纸原料。不同树种相比，米老排的纤维长度（1.53~1.70 mm）较大，但纸张整体强度指标未表现出明显优势；黑格的木材基本密度（0.442~0.586 g/cm3）较大，残碱量（10.0~13.8 g/L）和卡伯值（18.0~21.4）较高；大叶栎的木浆黏度（1 066~1 237 mL/g）较高，纸张整体强度指标也较优。不同林龄样木相比，5年生和12年生米老排、6年生黑格以及6~13年生大叶栎的制浆造纸综合性能较优，而13年生米老排、10年生黑格以及15年生大叶栎的纸张整体强度指标较低，表明3个速生阔叶树种适于培育短轮伐期纸浆林。 |
| Abstract:Wood basic density， fiber morphologies， and pulping and papermaking properties of 5 to 15 years old Mytilaria laosensis， Albizia odoratissima， and Castanopsis fissa as well as a control of 7-year-old Eucalyptus grandis × E. urophylla were investigated， to comprehensively evaluate the applicability of these raw materials for the pulping and papermaking. The results showed that under the evaluation of physical properties of the paper according to coordinate integrative assessment method， scores for the three tree species （0.59~19.91） were smaller than that of the control of Eucalyptus （21.25）， and all of them were superior raw materials for the pulping and papermaking. Compared with different tree species， the fiber length （1.53~1.70 mm） of Mytilaria laosensis was larger， but the overall strength indices of the paper showed no significant advantages. The wood basic density （0.442~0.586 g/cm3） of the Albizia odoratissima， residual alkali content （10.0~13.8 g/L） and Kappa value （18.0~21.4） of pulp from it were higher. The viscosity （1 066~1 237 mL/g） of pulp from Castanopsis fissa was higher， and the overall strength indices of the paper were superior. As for a comparison among groups with different tree ages， the pulping and papermaking properties of 5-year-old and 12-year-old Mytilaria laosensis， 6-year-old Albizia odoratissima， and 6 to 13 years old Castanopsis fissa were better， while the overall indices strength of papers of 13-year-old Mytilaria laosensis， 10-year-old Albizia odoratissima， and 15-year-old Castanopsis fissa were lower， indicating that the three species of fast-growing broad-leaved trees were suitable for cultivating short-rotation pulp forests. |
