本文着重从纤维形态和木材密度方面对顺义、菏泽、廊坊3个地区22株欧美杨试样进行分析,为探讨其制浆造纸适性提供了一定的理论依据。研究结果表明,进行测试的22株欧美杨试样中,纤维长度分布在0.76～1.19mm之间,其中廊坊地区沙土6年生欧美杨107纤维长度最长,达到1.182mm;纤维长宽比分布在27～57之间,其中有14株欧美杨的纤维长宽比大于45,具有较高的制浆造纸研究价值;在木材基本密度方面,大部分试样的基本密度在0.3～0.4g·cm-3,密度较小。
This paper focuses on the analysis of 22 strains of Populus tomentosa from the aspects of fiber morphology and wood density in Shunyi, Heze and Langfang so as to provide theoretical basis for the discussion of the adaptability of pulping and paper making. The results showed that the fiber length distribution of 22 European and American poplar cultivars tested ranged from 0.76 to 1.19 mm. The 6-year-old poplar 107 in Langfang area had the longest longest fiber length, reaching 1.182 mm. The fiber length-width distribution 27 to 57, of which 14 strains of European and American poplar fiber aspect ratio greater than 45, with higher pulp and paper research value; the basic density of wood, most of the sample’s basic density of 0.3 ~ 0.4g · cm -3, the density is smaller.
