摘　　要：以轻型基质泥炭土、珍珠岩、废菌棒和稻谷壳为基料,采用4因素3阶单形重心混料试验设计,运用两阶段多目标决策方法进行综合评价,开展轻型基质配方对木荷Schima superba,紫楠Phoebe sheareri和黄檀Dalbergia hupeana等3个阔叶树种容器苗苗木出圃品质影响的研究。结果表明:不同基质配方对3个阔叶树种容器苗的苗高、地径、高径比及生物量、苗木品质指数等影响均达到显著水平。基质类型可按泥炭土的体积百分比进行划分:泥炭土体积分数占70%为促生型,60%为中等型,40%为缓生型。研究认为,在生产中不同树种应采用不同的基质类型:紫楠等苗期生长缓慢树种选择促生型,木荷等苗期生长中等树种选择中等型,而黄檀等苗期速生树种可选择缓生型。For bi-level,multi-objective decision-making,the effects of four light medium formulas（peat soil,perlite,waste mushroom-stick,and rice chaff） on container seedling quality of three broadleaf tree species：Schima superba,Phoebe sheareri,and Dalbergia hupeana,were studied.A single shape barycenter design with four mediums,three species,and three levels having 30 replications was used.Results of the medium formulas showed significant differences（P0.01） in species for height,ground diameter,ratio of height to diameter,biomass,and quality index.For peat soil,70% peat promoted growth,60% peat showed moderate growth,and 40% peat inhibited growth.For best production,P.sheareri having early but slow growth should use a medium that promotes growth,S.superba having moderate growth should use a medium that moderately promotes growth,and D.hupeana having fast growth should use a medium that inhibits growth.
