摘　　要：针对干热河谷地区特殊地理环境,采用无纺布容器,以塑料容器为对照,研究不同材质及规格的容器对大叶相思苗木生长和生物量的影响.结果表明,无纺布容器及规格对大叶相思苗木的高、地径生长量,Ⅰ级侧根条数,苗木总生物量,根生物量有显著的影响;对大叶相思苗木质量进行综合评价.结果表明,大叶相思苗木培育的最佳容器为无纺布8 cm直径容器,其次是无纺布6 cm直径容器.Because of the dry-hot valley＇ s special environment, the authors used non-woven fabrics as seedling containers, contrasting to plastic containers, to study the impact of different sizes of containers on the Acacia auriliformis＇ seedling growth and biomass. The result showed that non-woven fabrics containers and their specifications have a significant impact on the seedling＇ s height, diameter growth, the number of Grade I lateral roots, total biomass of seedling and roots. The integrated evaluation on seedling quality of Acaccia auriliformis revealed that 8 cm-diameter non-woven fabric container was the optimal container, and 6 cm-diameter was the second.
