| 摘 要： | 对广东省东莞市樟木头林场6年生巨桉、柳桉、大花序桉、粗皮桉、托里桉5种桉树的灰分含量、干重热值和去灰分热值进行研究.结果表明:5种桉树的灰分含量、干重热值和去灰分热值因品种而异.各品种的灰分含量较低,在1.75%～3.96%之间,高低顺序为托里桉粗皮桉大花序桉巨桉柳桉;干重热值和去灰分热值分别在17.19～18.15 kJ/g与17.90～18.59 kJig之间,干重热值高低顺序为巨桉柳桉粗皮桉大花序桉托里桉,去灰分热值为粗皮桉巨桉柳桉大花序桉托里桉.单株干重热值与去灰分热值分别在783.30～1 808.65 MJ/株与804.97～1 843.52 MJ/株之间,排列顺序分别为巨桉粗皮桉大花序桉柳桉托里桉、巨桉粗皮桉大花序桉托里桉柳桉.综合分析,巨桉的灰分含量低、热值高,符合理想植物燃料的要求,且其总生物量大,可选作生物质能源树种.

| Abstract: | Five eucalypt species planted in Guangdong Zhangmutou Forest Farm were investigated in terms of biomass, and their ash contents and caloric values were determined. The results showed that there were differences in ash content, gross caloric value (GCV) and ash free caloric value (AFCV) among the 5 species. The ash contents were low, ranging from 1.75% to 3.96% in the decreasing order of E. torelliana>E. pellita>E. cloeziana> E. grandis> E. saligna; the gross caloric values (GCV) from 17.19 kJ/g to 18.15 kJ/... |
