【摘要】 在随机抽取木材样件并进行材质材性测定的基础上,通过典型正交分析,研究了柏木材质的宏观生态变异规律。结果表明林型、立地类型、栽培区和经营类型的改变显著地影响到柏木的材质材性要素。与阔叶树种混交显著增大了气干密度、管胞长度和年轮宽度,提高了木材抗压,抗弯强度;随着立地的贫瘠化,木材抗压、抗弯强度增大;栽培区和经营类型的改变主要通过调节木材数量生长影响及材质、材性。研究结果为柏木材质定向培育提供了科学的措施依据。更多还原

【Abstract】 Based on random sampling in the field and wood quality measurements the macro—ecological variation pattern of wood quality of Cupressus funebris Endl. was studied with typical orthogonal analysis. It is indicated that wood quality factors are. significantly changed in response to the variation of forest type, site, planting area and management regime. Intercropping with soft broadleaved trees has efffectively increased wood density, fiber — tracheid length and average ring width, enhanced wood crushing and bending strength. With site deterioration the wood crushing and bending strength is increased. Change of management regime and planting area Causes wood quality variation through growth regulation. The results provide cypress silvicultural practice with scientific更多还原
