摘　　要：采用随机区组试验设计方法,开展了基质配比和容器规格对武当木兰(Magnolia sprengeri)容器苗生长影响的研究。结果表明:不同基质配比和容器规格对苗木质量均有显著影响。以腐殖质为主的基质配比容器苗生长较好,而以黄绵土或沙土为主的基质配比容器苗生长较差;武当木兰幼苗根系发达,从生产实际出发,容器规格以10 cm×20 cm最佳。提高武当木兰容器育苗质量的最佳培养方案为:50%腐殖质+50%细河沙,选用10 cm×20 cm的容器,该组合既能保证容器苗的苗高、地径、单株生物量等各项指标充分生长,又能节约育苗成本,同时根系与基质能形成紧密的根系团。A randomi experimental design was conducted to investigate the effects of growth medium and container size on growth dynamic of Magnolia sprengeri Pamp.. The result indicated that the medium compositions and container size had a significant influence on seedling growth. In general, seedlings grown in containers with medium composed of humus grew extremely well, while seedlings grown in containers with yellow soft soils or sandy soils showed a bad growth performance. Because M. sprengeri had a strong root system, it was found that containers with 10 cm ×20 cm dimensions provided the best growth of the seedling. The best growth medium needed 50% humus and 50% river sand. The implementation of the growth protocol mentioned above guaranteed optimal growth in terms of seedling height, diameter, and biomass. The protocol also had potential to save costs associated with the much-valued seeding growth, meanwhile the root-soil system had potential to form a good root cycling.
