季节性淹水对长江滩地69杨木材材性及其变异的影响

以安微新洲滩地上生长的６９杨为材料，研究季节性淹水对６９杨木材材性及其变异的影响。结果表明，与未淹水相比，长江滩地季节性淹水对６９杨纤维形态特征影响不大，０．０５水平下方差分析检验不显著；对木材微纤丝角，木材密度，木材干缩率和力学性质影响较大，０．０５水平下方差分析检验显著，其中，微纤丝角，基本密度，抗弯弹性模量，抗 度和气干体积缩率分别增加了１５．６％，５．９％，１５．７５，１７．２％和２８．５

Effect of Seasonal Flooding on Wood Properties and Variation of Poplar 69 Grown in the Beaches of Changjiang River

The wood properties of poplar 69 were tested,which was collected from Xingzhou beaches of Changjiang river where seasonal flooding usually takes place.The results showed that seasonal flooding gave a significant effect on poplar 69's wood properties including microfibril angle,basic density,MOE,MOR and air dry volumetric shrinkage with the increase of 15 6%,5 9%,15 7%,17 2% and 28 5% respectively,although its effect on fiber's morphology of poplar 69 was very little.
