摘要
对降香黄檀(Dalbergia odorifera)的树皮率、心材率,木材密度进行了研究。结果表明:降香黄檀树皮体积百分率及质量百分率平均值分别为20.14%、13.77%;心材百分率平均值为30.53%,心材形成的年龄为9～15 a;生材密度平均值为1.064 g/cm3;基本密度平均值为0.715 g/cm3;生材含水率平均值为49.21%。降香黄檀树皮体积百分率及质量百分率均随着树高的增加而增加;生材密度及心材率随着树高的增加而减少;基本密度随着树高增加,呈大—小—大—小的趋势变化;生材含水率随着树高的增加,呈小—大—小—大的趋势变化。
Bark percentage, heartwood percentage and wood density of Dalbergia oclorifera were studied. The results showed that the average value of bark volume percentage and quality percentage of D. oclorifera were 20.14 % and 13.77 % respectively; the average value of heartwood percentage was 30.53% and the formation age of heartwood was 9-- 15 a; the average value of green density was 1. 064 g/cm^3 ; the average value of basic density was 0. 715 g/cm^3 ; the average value of moisture con- tent of green wood was 49.21% . The park volume percentage and quality percentage increased with the increase of height, while green density and heartwood percentage decreased. Basic density showed the trend of high-low-high-low with the increase of height, while the moisture content of green wood was contrary （low-high-low-high）.
