| 摘 要： | 采用排水法、体积法及质量法对阴香树的生材密度、含水率、树皮率及心材率进行测定.结果表明：阴香的生材密度从髓心向外北向呈现先降低后增大的变化趋势,而南向则呈现逐渐降低的趋势,在树高方向生材密度变化较为波动,但基本上呈现先增大后减小的趋势,其平均值为1.210g/cm3.阴香木的基本密度从髓心出现先降低后增大的规律,在树的高度方向上表现出先减小后增大再减小的趋势,阴香木基本密度的平均值为0.548g/cm3.阴香木的生材含水率从髓心位置向外逐渐减小,测试的生材含水率平均值为122.5％.树皮体积百分率及质量百分率的变化规律是均随着树高的增加而增加,其平均值分别为13.86％和15.2％.随着树木高度的增加,心材率反而降低,其平均值为42.0％.

| Abstract: | The green density, moisture content, bark percentage and heartwood percentage of Cinnamomum burmannii were studied by drainage method, volumetric and quality method. The resucts showed that the green density decreased and then increased in the north from pith to sapwood, and had a gradual decrease in the south. It showed great volatility with increase of height, but ba- sically presented the trend of increasing first and then decreasing with average value of 1. 210 g ~ cm-3 The basic density of the Cin- namomum burmannii appeared to have a tendency that decreases and then increase from pith to sapwood, but it showed the trend of de- creasing first, then increasing, and finally decreasing with the increase of height with average value of 0. 548 g ~ cm-3 The moisture content of green wood of Cinnamomum burmannii decreased from pith to sapwood with average value of 122. 5%. The bark volume per- centage and bark quality percentage had a similar change, they increased with height increasing, and the average value of those were 13.86% and 15.2%, respectively. The heartwood percentage decreased with height increasing, and the average was 42. 0%. |
