文摘内容 The fiber morphology and pulping properties oftriploid of populus tomentosa from plantation atdifferent ages were investigated in the paper, also themain chemical compositions were determined. Theresults showed that the difference of chemicalcompositions is not significant, and the extractivecontents become bigger in some sort with age, thedifference of length weighted mean length of fiberalso is not significant, and coarseness of fiber hastrend of augment by degree, while the fines contentincreases obviously with age. That difference ofpulping properties between chemical pulping (KPprocess and Soda-AQ process) and chemimechanicalpulping (SCMP process and APMP process) is notsignificant, which is consistent with the analysis ofchemical composition and fiber morphology.Considering comprehensively, the tree age of 5 yearsis better for paper making industry, also the mixedpulping with different ages of the triploid of populustomentosa is feasible with steady pulp quality。
