| 摘 要： | 不同年龄栓皮栎的灰分含量、干质量热值和去灰分热值是栓皮栎能源开发利用的重要基础。通过对5个年龄栓皮栎不同器官热值、灰分含量的分析,得出:平均灰分含量从高到低时的树龄依次为46、36、17、57、27 a;枝或干的灰分含量低于叶或皮。平均干质量热值从高到低的树龄依次为27、57、36、17、46 a;树叶、树皮、树干的干质量热值与灰分含量均呈不显著负相关,树枝的干质量热值与灰分含量间为极显著线性负相关,平均干质量热值与灰分含量呈显著线性负相关;枝或干的干质量热值均低于叶或皮。平均去灰分热值从高到低时的树龄依次为57、27、36、17、46 a;枝或干的去灰分热值均低于叶或皮。从热值与栓皮栎能源林的经营成本考虑,17、27、36、46、57 a的5个栓皮栎年龄段中,27 a可为栓皮栎能源林的理想经营年龄。

| Abstract: | Ash contents,gross caloric values and ash free caloric values at different ages were important information for exploiting and utilizing energy of Quercus variabilis.Caloric values and ash contents in different tissues of Q.variabilis at five different ages were studied in this paper.Results showed that average ash contents decreased in the order of the 46th,36th,17th,57th and 27th year.Ash contents of branch or trunk were lower than that of leave or bark.Average gross caloric values decreased in the order o... |
