摘　　要：通过盆栽土培试验方法,研究了施肥与不施肥(对照)条件下东方百合、麝香百合和亚洲百合3个切花百合品种的钾素吸收规律。结果表明:随着生育期进展,各品种的切花百合地上部各器官含钾量均逐渐降低,地下部器官根和鳞茎则依品种和施肥的不同而表现出差异。鳞茎中的钾素支撑切花百合的前期地上部生长的钾素需求,经历的时间3个品种基本一致,均为47d。钾素快速吸收期品种之间存在差异,东方百合由花芽分化至切花,历时81d;麝香百合由花芽分化至切花,历时50d;由亚洲百合10月6日至切花,历时25d。施肥均提高了3个品种后期整株的钾积累量,但出现时期因品种而不同,东方百合最早、麝香百合次之、亚洲百合最迟。Through soil incubation experiment in greenhouse, the phosporus uptake in 3 hybrids of cut-flower lily （i. e Asiatic hybrids Var. Prato, Longiflorum hybrids Var. Snow Queen, Oriental hybrids Var. Siberia） was studied under fertilization and CK conditions. The results showed that the potassium concentration in stem and leaf for 3 hybrids was decreased during the whole procreation stage, but the change of the potassium concentration in root and bulb was depended on the variety and fertilization treatment, The plant rnainly used the potassium stored in the bulb during prophase （be- fore 47 days） for 3 hybrids of lily. The period when potassium was rapidly absorbed was about eighty-one days from bud differentiation to harvest for Oriental hybrids lily, fifty days from bud differentiation to cut-flower for Longiflorum hybrids lily, and was about twenty-five days before cutting flower for Asiatic hybrids lily.
