摘　　要：为了研究不同种植密度对东方百合"西伯利亚"生长及切花品质的影响,试验选用周径16～18cm的东方百合"西伯利亚"为试材,分别设32株·m-2(处理A)、44株·m-2(处理B)、52株·m-2(处理C)3个种植密度处理。结果表明,不同种植密度下的东方百合"西伯利亚"生长发育进程的总体趋势基本一致,种植密度对东方百合"西伯利亚"生长发育进程的影响主要出现在植株生长发育的中后期,但处理间的差异不显著;种植密度对东方百合"西伯利亚"的生物学性状具有一定影响,其中处理A的叶片数、比叶重、基根均长以及茎根均长都显著高于处理C;种植密度对东方百合"西伯利亚"的干物质积累和分配存在一定影响,除了切花产量之外,不同种植密度下的东方百合"西伯利亚"的其他切花品质指标虽然存在一定差异,但均不显著。因此,适当密植不仅对东方百合"西伯利亚"的生长和切花品质不会造成较大的影响,而且还可以有效地利用各种资源,增加单位面积的切花产量,进而提高切花生产企业的经济效益。An experiment to study the effects of different planting densities（Treatment A： 32 plants·m-2,Treatment B： 44 plants·m-2,Treatment C： 52 plants·m-2） on growth and quality of cut flowers of Oriental Lily ＂Siberia＂（bulb size：16～18 cm） was carried out.The results of experiment indicated that the growth and development processes of Oriental Lily ＂Siberia＂ under all planting densities were extremely similar on the whole and the effects of planting density on the growth and development process of Oriental Lily ＂Siberia＂ mainly appeared in the middle and late stages,however,the differences among treatments were not significant.Planting density had some impacts on the biological characteristics of Oriental Lily ＂Siberia＂ and leaf number,specific leaf weight,mean basal root length and mean stem-root length of treatment A were all significantly higher than those of treatment C.Planting density also had some effects on dry matter accumulation and partitioning of Oriental Lily ＂Siberia＂,but the differences among treatments were still not significant.In addition to cut flowers production,although planting density also had some impacts on other indicators of the quality of cut flowers of Oriental Lily ＂Siberia＂,but no significant difference among treatments was detected.Thus,appropriately adopting a high planting density not only has no significant effects on growth and quality of cut flowers of Oriental Lily ＂Siberia＂,but also efficiently makes use of various resources,markedly increases cut flowers production per unit area and ultimately improves the economic efficiency of enterprises.
