摘　　要：为了探究不同育苗方式对草莓育苗的影响,本试验以‘红颜’草莓品种为试材,研究了高架育苗、穴盘育苗和土壤育苗3种方式对草莓母株匍匐茎生长、子苗质量和开花时期以及假植对子苗质量和花期的影响。结果表明,3种育苗方式母株抽生匍匐茎数量和繁苗系数差异显著,表现为高架育苗>穴盘育苗>土壤育苗。高架育苗和穴盘育苗的子苗株高、茎粗、叶柄长、叶面积、SPAD值均明显高于土壤育苗,且显著提高了幼苗地下部鲜干重、壮苗指数、根系活力以及根系总长度、根系表面积、总根尖数。高架育苗、穴盘育苗和假植均促进草莓花芽分化和提早开花。由此得出,繁育草莓子苗的质量与育苗方式密切相关,以高架育苗效果最佳,其次是穴盘育苗。The effects of different seedling methods on seedling growth of strawberry cultivar ‘Hongyan’ are largely unknown. In this study, the effects of elevated seedling, plug seedling and soil seedling on stolon growth, seedling quality and flowering time of strawberry were investigated as well as the effects of sham planting on quality of seedlings and flowering time. The results showed that the number of stolons and seedlings were significantly greater in elevated seedling than that in the other two seedling methods and was the lowest in soil seedling. Additionally,elevated and plug seedlings also presented obvious advantages in plant height, stem diameter, petiole length, leaf area and SPAD value of seedlings. Furthermore, the positive effects on the underground biomass, fresh and dry weight,root activity, total root length, root surface area and total root tip number of seedlings were also discovered between the elevated and plug seedlings. The flower bud differentiation and flowering of strawberry were promoted by elevated seedling, plug seedling and sham planting. In summary, the cultivation of quality seedlings is affected be the ways of seedling. And the elevated seedling method is the best followed by the plug seedling.
