| 摘 要： | 目的]比较2种相思树种树皮密度、树皮率及木材密度,为木材加工利用提供科学依据。方法]伐倒5年生的马占相思和厚荚相思2个相思树种各10株样木,在胸径处锯取5 cm厚圆盘,用排水法测定木材基本密度、树皮基本密度和树皮率。结果]马占相思木材基本密度平均值为407 kg/m3,厚荚相思为418 kg/m3;马占相思树皮基本密度的平均值为376 kg/m3,厚荚相思为456 kg/m3;马占相思的树皮率为16.5%,厚荚相思为14.2%。结论]厚荚相思的木材和树皮基本密度都高于马占相思,马占相思的树皮率大于厚荚相思的树皮率。

| Abstract: | Objective]The bark basic density,percent of bark and the timber basic density of Acacia mangium and Acacia crassicarpa were studied in order to provide scientific basis for utilization of the wood.Method] 5 cm thick disk was taken by chain saw in diameter at breast height place.Drainage method was used for determining timber basic density,bark basic density and percent of bark.Result] The mean value of timber basic density of Acacia mangium is 407 kg/m3,and Acacia crassicarpa is 418 kg/m3;The mean value of bark basic density of Acacia mangium is 376 kg/m3,and Acacia crassicarpa is 456 kg/m3.The mean value of bark rate of Acacia mangium is 16.5%,and Acacia crassicarpa is 14.2%.Conclusion]The timber basic density and the bark basic density of Acacia crassicarpa are higher than those in Acacia mangium.The cortices rate of Acacia mangium is higher than Acacia crassicarpa. |
