摘要
研究速生桉不同树龄生材密度及树皮率的变异性,采用排水法测定生材密度,体积法及质量法测定树皮率。结果表明:5 a生、6 a生、7 a生速生按的生材密度分别为1.033、1.037、1.036 g·cm^(-3),不同树龄的速生桉生材密度差异不显著。5 a生、6 a生、7 a生的树皮体积百分率分别为17.56%、16.29%、13.94%,不同树龄的速生桉树皮体积百分率差异显著。5年生、6年生、7年生的树皮质量百分率分别为18.34%、14.57%、11.21%,不同树龄的速生按树皮质量百分率差异显著。
Variations of green density and bark percentage of fast-graoing Eucalyptus were studied. The green density was tested by drainage method, and bark percentage was tested by measuring volume and quanlity. For the plants of five, six and seven-year-old fast-growing Eucalyptus, the green densities were 1. 033, 1. 037 and 1. 036 g ·cm^-1 respectively, and the variations were unremarkable among different ages. The bark volume percentages were 17.56%, 16.29% and 13.94% respectively, and the variation was significant. The bark quanlity percentages of five year, six year, seven year were 18.34%, 14.57% and 11.21% respectively, and the variations were significant.
