| 摘 要： | 对观光木的生材密度、含水率、树皮率及心材率进行测定分析,结果表明:观光木的生材密度从髓心向外呈先减小再增大的趋势,随着树高的增加,亦呈先减小再增大的趋势,其平均值为0.873 g.cm-3;基本密度自髓心向外逐渐增大,随着树高增加,呈先减小后增大再减小的趋势,其平均值为0.423 g.cm-3;含水率从髓心向外呈减小的趋势,随着树高的增加,呈先增大后减小再增大的趋势,其平均值为108.4%;树皮的体积百分率及质量百分率均随着树高的增加而增加,其平均值分别为13.5%、15.8%;心材率随着树高的增加而减少,心材百分率平均值为15.6%。

| Abstract: | The green density,moisture content,bark percentage and heartwood percentage was studied for Tsoonpiodendron odorum.The research showed that:the green density had a "decreasing" and then "increasing" direction from pith to sapwood,had a similar direction with increasing height,the average was 0.873 g·cm-3.The basic density increased from pith to sapwood,had a "decreasing" then "increasing" and then "decreasing" direction with increasing height,the average was 0.423 g·cm-3.The moisture content of green wood decreased from pith to sapwood,had a "increasing" then "decreasing" and then "increasing" direction with increasing height,the average was 108.4%.The bark volume percentage and bark quality percentage increasing with adding height,and bark volume percentage and bark quality was 13.5% and 15.8% respectively.The heartwood percentage decreasd with increasing height,and heartwood percentage average was 15.6%. |
