对人工林杨树木材小×钻4707#杨的纤维长度、纤维直径、纤维壁厚等纤维形态特征指标进行了系统的测试。结果表明:在径向上,木材纤维长度、纤维宽度的变异都是自髓心向外开始逐年增大,此后再逐渐减小或保持平稳;而纤维壁厚变化幅度不大。纤维形态各指标的径向变异均要大于轴向变异。
The fiber length, fiber diameter, fiber wall thickness and other fiber morphological characteristics of poplar wood × Drilling 4707 # poplar were systematically tested. The results showed that in the radial direction, the variation of wood fiber length and fiber width all began to increase year by year from the medullary center and then gradually decreased or remained stable. However, the variation of fiber wall thickness was not significant. The radial variation of each index of fiber morphology should be larger than the axial variation.
