测量了不同海拔、树龄的杉木人工林的管胞形态特征,并初步研究了管胞长度与年轮宽度、晚材率、木材密度以及有关力学强度(顺纹抗压、抗弯强度)的相互关系。可利用管胞形态(长度、直径、胞壁厚度)区分成、幼龄材的界限范围。 The tracheid morphological characteristics of Cunninghamia lanceolata plantations with different altitudes and ages were measured. The relationship between tracheid length, ring width, latewood rate, wood density, and relevant mechanical strength (compressive strength and flexural strength) relationship. Can be used to tracheid morphology (length, diameter, cell wall thickness) is divided into the boundaries of young wood.
