| 摘 要： | 对广东廉江石岭林场5年生尾巨桉不同器官的燃烧特性因子、物质组成成分和营养元素等指标进行了研究,并做了相关性分析。结果表明:5种器官去灰分热值在18.57~21.09 kJ·g~(-1)间,排序为叶片树枝树根树干树皮;去灰分热值和干质量热值、灰分相关显著,和粗纤维、粗蛋白、粗脂肪、全氮都显著相关,尾巨桉不同器官的热值受其物质成分及营养元素的影响。

| Abstract: | We studied combustion characteristics, material composition and nutrient elements in different component tissues of 5 years old Eucalyptus urophylla×E.grandis at Shiling forest farm in Lianjiang, Guangdong, and examined associations among component tissue characteristics. Ash free calorific values (AFCV) of the 5 different component tissues ranged from 18.57 to 21.09 kJ·g-1, with their rank order by AFCVs being: leaves>branches>roots>stem-wood>bark. AFCV, gross caloric value and ash content were significantly correlated with each other, as were crude fiber, crude protein, crude fat and total nitrogen. AFCV of E.urophylla×E.grandis's component tissues were found to be associated with their material composition and levels of key nutrient elements. |
