摘　　要：以多菌种生物制浆工艺为基础,利用10个新选育的杨树无性系为材料,从基本密度、纤维形态、化学成分等方面探索杨树超短轮伐条材生物制浆可行性,结果表明:品种间条材材性差异明显,杨树超短轮伐条材的纤维形态、化学成分等制浆特性均能满足制浆造纸的需求;用1、2 a条材进行生物制浆完全可行,其得浆率为65.0%~72.0%,浆纸质量达国标阔叶木浆的Bk-C标准。Based on the multiple fungi biopulping technology,the wood basic density(WBD),fibre form and chemical components of 10 poplar clones were used to study the biopulping feasibility of poplar minirotation coppice shoot.The result showed that the wood quality characteristics of 1 and 2 years-old poplar could fulfill the technical requirement of pulping and paper making.Coppice shoots can be used to biopulping.The pulp yield of biopulping was between 65.0% and 72.0%,and the quality of pulp was up to the par of s...
