为了探讨树龄对桉树杂交种燃料特性的影响,对2-6年生的幼树和20年生的成熟树木材基本密度、发热值、近似和最终参数的变异性进行了测定和分析。结果表明,2-6年生的幼树的木材基本密度没有显著变化,平均值为0.55-0.58g.cm-3。成熟树木材的发热量高于幼龄材,但幼龄树木材的灰烬含量要高于成熟材。不同树龄木材的挥发物质和固定碳的含量没有明显的变化趋势。研究表明,桉树杂交种成熟材的燃料特性稍好于幼龄材的燃料特性。
In order to investigate the effect of tree age on the eucalyptus hybrid fuel characteristics, the variability of wood basic density, calorific value, approximate and final parameters of young and 20-year-old saplings aged 2-6 years were measured and analyzed. The results showed that the basic wood density of saplings aged 2 to 6 years did not change significantly, with an average of 0.55-0.58g.cm-3. Mature trees have higher calories than juveniles, but young trees have higher ash content than mature trees. There is no obvious trend of volatile matter and fixed carbon content in different ages of timber. Studies have shown that the fuel properties of mature eucalyptus hybrids slightly better than those of young wood fuel properties.
