黑龙江省主要杨树纤维用材品种纸浆性能综合评价

Comprehensive Evaluation on Pulp Properties for Fiber Timber Varieties of Poplar in Heilongjiang Province

选择黑龙江省7个主要杨树纤维用材品种为研究对象,测定了木材纤维形态、化学成分和成浆性能,分析了林龄与主要纸浆性能间的相关关系,对7个品种纸浆性能进行了综合评价。试验结果表明:7个品种的纤维长度为0.88～1.17mm,纤维素含量为49.28%～59.77%,粗浆得率为50.41%～54.97%,上述指标均达到或超过优质纸浆标准;林龄与纤维长度、纤维素含量和粗浆得率间无显著相关关系;纸浆性能综合评价由高至低的顺序为黑青杨>小青黑>银中杨>大青杨>青山杨>小黑杨>迎春5号。

Selecting the seven major poplar fiber timber varieties in Heilongjiang Province as the research object, wood fiber morphology,chemical composition ~ slurry performance were measured; relationship between forest age main pulp properties were analyzed; pulp properties of seven varieties were comprehensively evaluated. Result shows that： fiber length of the seven varieties is 0.88-1. 17 ram, the cellulose content being 49.28%-59.77~/00, crude pulp yield being 50.41 ~//0 - 54.97 % ;the above targets are met or exceeded the quality pulp standards. Forest age ~ fiber length,cellulose content and coarse pulp yield have no significant correlation;the descending order of comprehensive evaluation on pulp properties is： Populus euramericana ＇ N3016＇ X P. ussuriensis 〉 Populus pseudo-siminii 5〈 P. nigra 〉Populus alba X P. berolinensis 〉Populus ussuriensis Kom. 〉 Populus pseudo-cathayana X P. deltoides Populus simonii X P. nigra 〉 Populus nigra X P. simonii.
