Abstract

Highland bamboo () is fast growing perennial plant that occurs as small holder plantation and naturally in the highlands of Ethiopia with a wide range of values and uses. This study assessed environmental conditions where the species grows, and related the sites-suitability information to other potential regions in Ethiopia. Field survey was conducted to growing areas in Ethiopia. Data were collected on dendrometric and environmental variables from field plots of 400 m of bamboo stands in three replications in each of the study districts in the regions. Consultations were also held with key informants, women, youth and elder focus group discussants on the common uses and production constraints of the species. The study identified wider uses of the species from being raw material for household utensils, furniture, fencing to building local houses in Ethiopia. Observations indicate that grows in the south, south-western, central and north-western highlands of Ethiopia at altitudes ranging from 2200 to 4000 m.a.s.l. It grows rapidly, where after planting from offset, starts to yield useable culm within three to four years. The species growing sites characteristics in the present study indicated that it's well performing in the altitudinal range between 2387 and 2979 m.a.s.l. We recommend promoting highland bamboo in Ethiopia for better culm yield on sites with elevation from 2300 up to 3500 m.a.s.l with mean annual rainfall >1200 mm, temperature varying from min. 6 °C to max. 30 °C and slope from 0 to 60% to attain optimum growth across the country.

摘要

高地竹()是一种生长迅速的多年生植物,以小农户种植园的形式存在,并且自然生长在埃塞俄比亚的高地,具有广泛的价值和用途。本研究评估了该物种生长的环境条件,并将适宜种植地点的信息与埃塞俄比亚的其他潜在地区进行了关联。对埃塞俄比亚的种植区进行了实地调查。从各研究区域内每个研究区的400米竹林样地中收集了树木测量和环境变量的数据,共进行了三次重复。还与关键信息提供者、妇女、青年和老年焦点小组讨论者就该物种的常见用途和生产限制进行了磋商。该研究确定了该物种在埃塞俄比亚有更广泛的用途,从家用器具、家具、围栏的原材料到建造当地房屋。观察表明,高地竹生长在埃塞俄比亚南部、西南部、中部和西北部的高地,海拔范围为2200至4000米(平均海平面)。它生长迅速,从竹鞭种植后,三到四年内就开始产出可用的竹竿。本研究中该物种生长地点的特征表明,它在海拔2387至2979米(平均海平面)的范围内生长良好。我们建议在埃塞俄比亚推广高地竹,以便在海拔2300至3500米(平均海平面)、年平均降雨量>1200毫米、温度在最低6°C至最高30°C之间且坡度为0至60%的地区获得更好的竹竿产量,从而在全国实现最佳生长。
