摘要
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 investigate the effect of fertilization on wood quality of Poplar 69(Populus deltoides cv.Ⅰ69/55),the key wood properties (fiber length, fiber width, double wall thickness, lumen diameter of fiber, wall thicknesslumen ratio, microfibril angle and basic density) of 20 Poplar 69 trees of 12 years old from 4 plots subjected for different fertilization treatments were determined and analyzed.The results showed that fertilization treatments had significant effects on double wall thickness at 01% level, lumen diameter of fiber at 5% level, wall thicknesslumen ratio at 01% level and microfibril angle at 1% level. No significant effect of fertilization had been found on fiber length, fiber width and basic density.These results provided some information for the silviculture of poplar plantation.
