摘要

在我国(包括研究地区),本地饲料和水果物种除了提供水果(食物)和饲料外,还为当地社区提供各种产品和服务。虽然关于本地饲料和水果物种的繁殖方法及其在当地的使用有着丰富的传统知识,但林业研究和推广工作却很少认识到这一点。这项研究的总体目标是调查埃塞俄比亚 Merhabete 地区本地饲料和水果物种的使用价值和繁殖方法。研究人员随机选取了 127 户家庭,就本地饲料和水果物种的使用和繁殖方法进行了访谈。研究表明,大多数本地饲料和水果物种被用作木柴(23.9%),其次是木炭(10.9%)、木材和建筑木材(10.6%)、栅栏(9.3%)、土壤肥力改良(9.1%)、农具(7.1%)和药物(3.3%)。本地饲料和水果物种(42.7%)是通过野化(自然再生)繁殖的,其余则是通过育苗(7.2%)、播种(6.06%)和切茎(4.8%)繁殖的。过度放牧(46.5%)、过度开发(22%)、气候变化/干旱(20.5%)和病虫害(11%)是研究地区本地饲料和果树/灌木物种再生的主要制约因素。因此,必须通过适当的研究或开发工作来减少所研究物种的繁殖限制。Ziziphus spina-christi (L.) Desf.、Faidherbia albida (Delile) A. Chev.、Cordia africana Lam.、Ximenia americana L.和 Acacia senegal (L.) Willd.是研究地区农民最喜欢种植的树种。驯化的重点应放在首选的前五个物种上,以促进物种保护和可持续利用。

Assessment of Use Values and Propagation Methods of Native Fodder and Fruit Species in Merhabete District, Ethiopia
Native fodder and fruit species provide various products and services to local communities besides their fruit (food) and fodder supply in our country including in the study area. Although, there is rich traditional knowledge on propagation methods of native fodder and fruit species and their local use, but little recognition has been given by forestry research and extension efforts to enhance them. The general objective of the study was to investigate the use value and propagation methods of native fodder and fruit species in the Merhabete district, Ethiopia. A total of 127 households were randomly selected and interviewed about local use and propagation methods of native fodder and fruit species. The study indicated that the majority of native fodder and fruit species were used for firewood (23.9%) followed by charcoal (10.9%), timber, and construction wood (10.6%), fencing (9.3%), soil fertility improvement (9.1%), farm tool (7.1%), and medicine (3.3%). Native fodder and fruit species (42.7%) were propagated through wilding (natural regeneration) and the remainder were propagated through seedlings (7.2%), seed (6.06%), and stem cutting (4.8%). Overgrazing (46.5%) followed by overexploitation (22%), climate change/drought (20.5%), and disease and pest (11%) were the major regeneration constraints to native fodder and fruit trees/shrubs species in the study area. Therefore, proper involvement either through research or development works are essential to reduce the propagation constraint of studied species. Ziziphus spina-christi (L.) Desf. followed by Faidherbia albida (Delile) A. Chev., Cordia africana Lam., Ximenia americana L., and Acacia senegal (L.) Willd. were the most preferred species for planting by farmers in the study area. Domestication should focus on the preferred top five species to promote species conservation and sustainable use.
