分别取用一元直线方程和一元幂函数方程对尾叶桉U6(E.urophylla U6)无性系立木木材的含水率与吸水率的关系进行研究、分析与探讨。分析结果表明:两个回归方程的结论一致,立木木材的含水率与吸水率两者呈负相关关系。经作检验含水率与吸水率的相关程度达高度紧密,相关显著性达极显著水平,精度可靠可供参考使用。研究中还发现:尾叶桉U6(E.urophylla U6)无性系立木生长在砖红壤,沉积沙壤和粗骨砖红壤的三个不同土壤类型上的立木木材的含水率的差异性均极显著;而生长在砖红壤上的立木与生长在沉积沙壤上的立木木材吸水率无显著差异,其余差异极显著。
The relationship between water content and water absorption of E. urophylla U6 clones was studied, analyzed and discussed by using the linear equation of one dimension and the power of one dimension respectively. The results show that the conclusion of the two regression equations is consistent. The moisture content and water absorption rate of Timber wood have a negative correlation. The tested water content and water absorption of the degree of closeness, the relevant significant significant level, the accuracy of reliable reference for use. The results also showed that there was significant difference in the water cut of timber of three different soil types of E. urophylla U6 clonal growth in brick red soil, sediment sandy soil and coarse-grained red soil ; While there was no significant difference in the water absorption of standing wood grown on brick red soil and standing wood on sediment sandy soil, the other differences were extremely significant.
