摘要： 通过盆栽土培试验方法,研究了东方百合、麝香百合和亚洲百合3个切花百合品种生物量动态及其与施肥的关系。结果表明,无论施肥与否,切花百合的前期生长主要是以消耗鳞茎为主,供地上部生长,生物总量基本保持不变,这时虽然3个品种的百合进入了不同的生育阶段,但它们所经历的消耗鳞茎的时间基本一致,大约为47 d。此后,东方百合和麝香百合的鳞茎生物量迅速增加,总量也随之增加,茎、叶干质量在生长后期降低;亚洲百合鳞茎生物量变化不大,茎、叶干质量不断上升,总量增加。施肥对3个品种整株生物量积累和切花商业品质影响不显著,但能显著改善部分品质指标性状如东方百合的花直径、麝香百合的叶片颜色、亚洲百合每株花蕾个数等;也能增加后期部分器官如东方百合叶片和根系、麝香百合的叶片等的生物量。

Abstract: Through soil incubation experiment in greenhouse,the nitrogen uptake in 3 hybrids cut-flower lily(i.e Asiatic hybrids Var.Prato,Longiflorum hybrids Var.Snow Queen,Oriental hybrids Var.Siberia) was investigated under fertilization and CK conditions.The results showed that whether fertilizer was applied or not,the plant mainly used the materials stored in the bulb before 47 d for 3 hybrids at the different procreation stages.After 47 d,the biomass of Oriental hybrids and Longiflorum hybrids was increased in bulb,it was decreased in leaf and stem,and the total biomass of cut-lily was increased.The biomass of Asiatic hybrids did not changed too much in bulb after 47 d,it was increased in leaf and stem,and the total biomass of cut-lily was increased.Fertilization did not markedly influence the biomass accumulation of whole plant and the market quality of cut-flower for 3 hybrids.However,some quality characters such as flower diameter of Oriental hybrids,leaf colour of Longiflorum hybrids and flower bud number per plant of Asiatic hybrids were evidently improved and the biomass of some organs such as leaf and root of Oriental hybrids and leaf of Longiflorum hybrids were significantly increased at harvest.
