| 摘 要： | 通过对檫树、酸枣、米槠人工林和天然林木材物理力学性质的测定和比较分析,结果表明:3种环孔材人工林木材除抗弯弹性模量、抗劈力和冲击韧性小于天然林外,其余指标均稍大于天然林.经差异显著性t检验表明:3种环孔材人工林和天然林木材物理力学性质指标中仅抗弯弹性模量、抗劈力和冲击韧性差异显著或极显著,其余指标差异不显著.研究结果为檫树、酸枣、米槠人工林培育提供科学依据. |

| Abstract: | Physical and mechanical properties of Sassafras tzumu,Cheorospondias axillaris and Castanopsis cartesii from plantation and natural forest were determined and analyzed.The results showed that the other indices of the three ring porous wood from plantation were slightly larger than those of natural forest except that elastic modulus of bending,impact toughness and resistance to cleavage from plantation were less than those of natural forest.The results of t test showed that there were significant difference or extremly significant difference on elastic modulus of bending,impact toughness and resistance to cleavage between plantation and natural forest only.The results would provide scientific basis for plantation cultivation of S Tzumu,C axillaris and C carlesii |
