摘要:
对柚木木材的生材性质进行研究，可对人工林柚木的合理加工和高效利用提供理论依据。采用体积法和质量法测定11年生的柚木树皮率，用排水法测定木材体积，并用测定得到的数据分析柚木的树皮率、心材率、生材密度、基本密度和生材含水率。研究结果表明：11年生柚木树皮体积分数和树皮质量分数随着树高的增加而增加，在树梢部位树皮率最高，平均值分别为26.26%，25.93%。心材率随着树高的增加而减小，心材在根部较大，树干根部心材率最大为47.63%，平均值为34.60%。生材密度随着树高增加而减小，平均值为1.094 g/cm3，自髓心向外，南向和北向都先减小后增大。基本密度随着树高增加呈现先减小后增加的趋势，平均值为0.558 g/cm3，自髓心向外，南向和北向均逐渐增加。生材含水率随着树高的增加而减小，平均值为97.32%，自髓心向外，南向跟北向均减少且数值基本相等。
Abstract:
In order to provide a theoretical basis for the rational processing and efficient utilization of planted teak wood, the green wood properties of Tectona grandis Linn. f. from the Guangxi Forestry Research Institute were studied. The bark percentage of 11-year-old T. grandis Linn. f. was determined by the volume and the quality method and the green wood volume were determined by the drainage method. The measured data were used to analyze the bark volume, heartwood percentage, green density, basic density and moisture content of green wood. The research showed that 1)The bark volume fraction and bark mass fraction of 11-year-old T. grandis Linn. f. increased with the increase of tree height, and the bark rate was the highest at the top of the tree, with an average of 26.26% and 25.93%, respectively. 2)The heartwood percentage decreasing with increasing height, heartwood was biggest in tree root, the heartwood percentage was 47.63%, and the average was 34.60%. 3)The green density decreased with the increase of tree height, with an average value of 1.094 g/cm3. 4）From the pith to to sapwood, south and north, the green density decreased first and then increased. The basic density decreased first and then increased with the increase of tree height, and the average value was 0.558 g/cm3. From the pith to sapwood, the basic density of south and north increased gradually. The moisture content of green wood decreased with the increase of tree height, with an average value of 97.32%. From the pith to sapwood, the south and the north decreased and the values were basically equal.
