| 中文摘要: |
| 为促进黑木相思人工林木材的合理高效、高附加值利用,对5年生和7年生黑木相思木材生
材性质展开研究。结果表明,5年生黑木相思木材平均生材密度、平均基本密度、平均树皮质量率、
平均树皮体积率、平均生材含水率及平均心材率分别为0.784 g/cm3、0.405 g/cm3、19.26%、
15.26%、94.94%及14.0%,7年生分别为0.875 g/cm3、0.458 g/cm3、16.63%、12.20%、99.63%及
31.4%。5年生和7年生黑木相思木材生材密度、基本密度、树皮质量率、树皮体积率及心材率差
异显著,生材含水率差异不显著。 |
| 英文摘要: |
| To promote rational and high-value utilization of plantation-grown Acacia melanoxylon timber,
this study investigated the green wood properties of 5-year-old and 7-year-old trees. The results showed
that the 5-year-old trees exhibited average green wood density of 0.784 g/3, basic density of 0.405
g/3, bark mass percentage of 19.26%, bark volume percentage of 15.26%, green wood moisture content
of 94.94%, and heartwood proportion of 14.0%. Corresponding values for 7-year-old trees were
0.875 g/3, 0.458 g/3, 16.63%, 12.20%, 99.63%, and 31.4%, respectively. Significant differences
were observed between the two age groups in green wood density, basic density, bark mass percentage,
bark volume percentage, and heartwood proportion, while no significant difference was found in
green wood moisture content. |
