异叶南洋杉人工林木材生材性质研究

Green Wood Properties of Araucaria heterophylla Plantation

为合理利用异叶南洋杉人工林木材,通过排水法、质量法和数值法对异叶南洋杉人工林的生材性质展开研究,结果表明,异叶南洋杉人工林木材树皮体积百分率、质量百分率、生材密度、基本密度和生材含水率的平均值分别为11.39%、13.78%、0.842 g/cm^(3)、0.394 g/cm^(3)和121.43%。随异叶南洋杉树高的增加,树皮体积百分率和质量百分率总体呈增大趋势;生材密度和基本密度总体呈下降趋势;生材含水率总体呈先升高后降低的趋势。以期为异叶南洋杉人工林木材的合理利用提供数据支持和理论支撑。

In order to make reasonable use of Araucaria heterophylla plantation wood, this paper used drainage method, mass method and numerical method to study the green wood properties of Araucaria heterophylla plantation. The results showed that the average bark volume percentage, mass percentage, green wood density, basic density and green wood moisture content of Araucaria heterophylla plantation were 11.39%, 13.78%, 0.842 g/cm^(3), 0.394 g/cm^(3) and 121.43%, respectively. With the increase of the tree height, the bark volume percentage and mass percentage showed an upward trend;the green wood density and basic density showed a downward trend;the green wood moisture content increased first and then decreased. This research provided data and theoretical support for the rational use of Araucaria heterophylla plantation wood.
