摘要
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。
In this essay, the fiber morphology and the wood basic density of 22 Populus x euramericanas in Shunyi, Heze and Langfang regions were tested and analysed, which provided theoretical basis for discussing their optimization and promotion in pulp and paper making. The results of the test shows that：the range of the fiber length of 22 Populus × euramericanas is from 0.76mm to 1.19mm, and the length of Populus×euramericanas 107 is the longest to 1.182mm. The length-width ratio is from 27 to 57,and the length-width ratio of 14 Populus x euramericanas are above 45, which have good pulp and paper making research value. Most of the Populus×euramericanas＇ basic density are 0.3-0.4 g·cm^-3, which is smaller than standard in the basic density.
