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.Ⅰ69/55),the key wood properties (fiber length, fiber width, double wall thickness, lumen diameter of fiber, wall thicknesslumen 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 01% level, lumen diameter of fiber at 5% level, wall thicknesslumen ratio at 01% 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.
