Abstract

The source of energy at household level in Ethiopia mostly comes from wood biomass. The increasing population and shrinkage of natural forests resulted in shortage of wood supply for energy. Hence, looking for fast-growing with better fuel wood characteristics is required to access wood and for the supply of fuelwood consumption. This study aims to select tree species with better biomass and good fuel wood characteristics. Seven tree species: Acacia polyacantha, Acacia abyssinica, Eucalyptus camaldulensis, Albizia lophantha, Acacia melanoxylon, Acacia decurrens, and Eucalyptus globulus were selected to study the growth performance, biomass and fuel wood characteristics. Six trees per species were randomly selected and harvested for fuel wood property (wood moisture, ash content and fiber content) analysis. Acacia abyssinica, Acacia polyacantha and Eucalyptus camaldunesis showed better survival rates than other species. The better height performance was recorded from Acacia .decurrens, Acacia polyacantha, Eucalyptus camaldulensis, and Eucalyptus globules. A. polyacantha and A.decurrens provided the highest biomass. A. decurrens showed the lowest wood moisture (31.1%) and wood density (0.76 g/cm3), and the lowest ash content (2.2%). Hence, A. decurrens and A. polyacantha are recommended for fuel wood due to high density, low moisture, and low ash content and good biomass production.

埃塞俄比亚谢瓦北部中高海拔地区薪柴生产树种的筛选

埃塞俄比亚家庭的能源来源主要来自木材生物质。人口的增长和自然森林的萎缩导致能源木材供应的短缺。因此，需要寻找具有较好薪柴特性的速生树种来获取木材和供应薪柴消费。本研究旨在选择生物量较好、薪柴特性好的树种。选取聚刺刺槐、深海金合欢、山梨树桉、白刺刺槐、黑梭子刺槐、秋叶刺槐和蓝桉7种树种，研究其生长性能、生物量和燃料木材特性。每个树种随机选取6棵，采伐后进行薪柴性质(木材水分、灰分和纤维含量)分析。深海金合欢、聚棘金合欢和桉树的成活率高于其他树种。黄花刺槐、聚棘刺槐、山梨树和蓝桉的高值表现较好。聚棘和花楸的生物量最高。木密度(0.76 g/cm3)和木材含水量(31.1%)最低，灰分含量(2.2%)最低。因此，由于密度高、湿度低、灰分含量低和生物质产量好，建议将槐和聚棘作为燃料木材。
