摘要
对西北农林科技大学对比试验林中的8年生秦白杨5号、西北杨系列2号和3号的木材材性以及纤维形态特征进行了研究。以毛白杨30号为对照,通过多重比较和方差分析。结果表明,西北杨2号、3号的物理力学性质与毛白杨30号的物理力学性质接近,是良好的板材原料。秦白杨5号的物理力学性能为4个品种中最差,但其纤维形态特征及材积生长量表现最优;秦白杨5号、西北杨系列2号、3号材积生长量都比对照组毛白杨30号的大,可以应用于木材加工业和纸浆造纸工业。
In this paper,the woods of 8-year-old poplar cultivars Qinbaiyang No.5 and Xibeiyang No.2 and No.3 were used to examine the properties and fiber morphologies.Populus tomentosa clone No.30 that is the main poplar cultivar planted in local area was taken as the control.Variance analysis and multiple comparison methods were adopted to process the data obtained.The results indicated that the physical and mechanical properties of Xibeiyang No.2 and 3 were similar to the control,they could be used as raw materials to make plumbers.The physical and mechanical properties of Qinbaiyang No.5 were the poorest among the four cultivars tested,however,its morphological properties and volume growth traits were the best among the four.Comprehensive test results showed that the volume growths of Qinbaiyang No.5 and Xibeiyang No.2 and No.3 were all higher than the control,indicating that they can be used in wood industry and pulp and paper industry.
