摘　　要：对施肥处理和未施肥处理两种条件下的 1 2年生 I-69杨 (Populusdeltoides Bartr cv.“Lux”ex I-69/ 5 5 )的年轮宽度、纤维长度、宽度、壁厚、腔径、长宽比、壁腔比、微纤丝角及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 :施肥处理可促进杨树生长 ;对年轮宽度、纤维宽度、腔径、壁厚、微纤丝角等有增大作用 ,但降低了纤维长度、长宽比等指标。经方差分析 ,施肥处理对 I-69杨木材解剖学特性的影响不显著。In order to investigate the effect of fertilization on wood properties of poplar 69 (Populus deltoides Bartr.cv.'Lux' ex I-69/55), the key wood properties (ring width, fiber length, fiber width, cell wall thickness,lumen,ratio of length to width, ratio of cell wall to lumen and microfibril angle) of poplar of 12 years old from 2 fertilization treatments (fertilized control) were determined and analyzed.The results showed that in the fertilized plantations,the poplars grow faster,implicating fertilization treatment had a positive effect on ring width, fiber width, lumen, cell wall thickness and microfibril angle, and had a negative effect on fiber length and ratio of length to width. Analysis of variance indicates that the selected fertilization treatment had no significant effect on the wood anatomical features of poplar 69.
