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.]
