对粗放与集约两种栽培措施下人工经济林核桃木材纤维形态特征进行了系统分析。结果表明 ,( 1 )与粗放管理的人工经济林核桃相比较 ,集约的纤维长度、宽度、壁厚、腔径、长宽比和壁腔比均小 ,方差分析表明只有纤维宽度、壁厚在 0 .0 5水平显著 ,其它特征均未达显著水平。 ( 2 )两种栽培措施下纤维长度、宽度、壁厚、长宽比和壁腔比的径向变异规律差别不大。 ( 3)集约管理的核桃的各种纤维形态特征和粗放管理的纤维长度、宽度、腔径和长宽比等特征的轴向差异均不显著 ;粗放管理的壁厚、壁腔比的轴向差异显著。 ( 4)两种栽培措施下的大部分纤维形态特征及其径向和轴向变异规律差异不大
The morphological characteristics of artificial walnut wood fiber were systematically analyzed under both extensive and intensive cultivation measures. The results showed that: (1) Compared with the extensively managed artificial economic forest walnut, the intensive fiber length, width, wall thickness, cavity diameter, aspect ratio and wall cavity ratio were small. The variance analysis showed that only the fiber width and wall thickness were 0 .0 5 significant level, other characteristics were not reached significant level. (2) The radial variation of fiber length, width, wall thickness, aspect ratio and wall-cavity ratio under the two cultivation measures is not obvious. (3) The characteristics of various types of fibers and intensive management of the fiber length, width, diameter and length-width ratio of the axial characteristics of the axial differences are not significant; extensive management of wall thickness, axial ratio of wall cavity ratio Significant difference. (4) The morphological characteristics of most of the fibers and their radial and axial variations under the two cultivation measures were not significantly different
