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。表6参9Abstract: 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（P＜0.01） 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.［Ch，6 tab. 9 ref.］
