| 摘 要： | 目的]以5年生马占相思为研究材料,对马占相思基本密度和树皮率进行研究,为马占相思的综合利用提供科学依据。方法]伐倒10株马占相思平均木,锯取圆盘,用排水法测定木材基本密度、树皮基本密度,并从体积和干重两方面测定马占相思的树皮率。结果]马占相思的木材基本密度平均值为407 kg/m3,树皮基本密度平均值为376 kg/m3,基本密度沿树干高度增加而减小。马占相思体积树皮率平均值为16.5%,重量树皮率平均值为15.4%,体积树皮率的平均值比重量树皮率的平均值大。结论]马占相思木材基本密度与大多数阔叶树材相比,处于中下水平;木材基本密度比树皮基本密度大。 |

| Abstract: | Objective] Taking 5 year-old Acacia mangium as the research object,the research would provide scientific basis for the comprehen- sive utilization of Acacia mangium. ~ Method] Wood density and bark density were studied by draining method. Bark rate of Acacia mangium was determined from two aspects such as volume and dry weight. Result ] The mean of wood basic density was 407 kg/m3, bark density was 376 kg/m3. The mean of the bark volume rate was 16.5% ,bark weight rate was 15.4% ,and the bark volume rate was higher than the bark weight rate. Conclusion] The basic density of Acacia mangium at a lower level ,wood basic density was higher than bark basic density. |
