摘要
为探讨竹材资源合理开发和高效加工利用,本文研究了不同海拔高度与坡向对毛竹干缩性的影响。结果显示:东北山顶毛竹、西南山脚毛竹的平均体积全干干缩率分别为18.030%、20.393%,平均体积气干干缩率为7.370%、8.856%;平均径向全干干缩率分别为9.513%、10.885%,平均径向气干干缩率分别为3.765%、4.897%;平均弦向全干干缩率为8.057%、9.004%,平均弦向气干干缩率为2.758%、3.367%;在0.05水平上经t检验,各指标均差异显著。
In this paper,in order for rational development and efficient processing and utilization of bamboo resources,a study was made on the influence of altitudes and slope aspects on the moso bamboo dry shrinkage property.The results showed that the mean volume full dry shrinkage rates were 18.030% and 20.393%respectively for the moso bamboo on the northeast ridge and southwest foothills with the mean volume air drying shrinkage rates of 7.370% and 8.856%respectively,mean radial full dry shrinkage rates of 9.513% and 10.885%,mean radial air drying shrinkage rates of 3.765% and 4.897%respectively,mean chordwise full dry shrinkage rates of 8.057% and 9.004%respectively and mean chordwise full air drying shrinkage rates of 2.758% and 3.367% respectively.There were significant differences among the indexes with T-test at 0.05 level.
