为了探索不同施肥处理对 -69杨(Populusdeltoidescv. -69/55)木材材性的影响规律,作者对4种施肥处理下的12年生 -69杨的纤维长度、宽度、双壁厚、腔径、壁腔比、微纤丝角及木材基本密度等材性指标进行了系统测试,并对测试数据进行了统计分析。结果表明:不同施肥处理对 -69杨的双壁厚、腔径、壁腔比和微纤丝角影响显著,而对纤维长度、宽度和木材基本密度影响不显著,其中双壁厚和壁腔比在各试验地之间差异达到0.1%显著水平,微纤丝角达到1%显著水平。
In order to explore the effects of different fertilization treatments on wood properties of Populus deltoides cv. -69/55, the author studied the effects of four fertilization treatments on the wood length, width, double wall thickness, Wall cavity ratio, microfibril angle and wood basic density and other material properties were systematically tested, and the test data were analyzed. The results showed that the effects of different fertilization treatments on double wall thickness, cavity diameter, wall cavity ratio and microfibril angle were significant, but no significant effect on fiber length, width and wood basic density. Among them, double wall thickness and wall cavity The difference between the experimental sites reached a significant level of 0.1%, and the microfibril angle reached a significant level of 1%.
