摘　　要：以设施栽培鲜切菊花主栽品种荷兰多头小菊‘Cedis’和多头菊‘Country’为研究对象,比较其鲜切菊花产量、观赏性状和对氮磷钾养分吸收、累积特性,以期为设施鲜切菊花优质生产和科学施肥提供依据。结果表明:两品种的产量无显著差异,多头小菊‘Cedis’的采收率和高等级鲜切花比例显著高于多头菊‘Country’,而鲜样质量和株高则以多头菊‘Country’较高。多头小菊‘Cedis’的氮和钾需求量显著高于多头菊‘Country’,分别高10.80%和35.03%,而磷需求量两者无显著差异。多头小菊‘Cedis’的养分吸收量为K>N>P,而多头菊‘Country’为N>K>P。移栽30~45 d时(茎生长期—花芽分化期),鲜切荷兰菊氮、磷、钾阶段累积量最大。In order to provide theoretical basis for high quality and scientific fertilization of chrysanthemum,we carried out a field experiment to compare the yeild,ornamental characters and nutrient uptake and accumulation characteristics between‘Cedis＇ and‘Country＇which are two leading varieties of chrysanthemum in the Netherlands. The results showed that the yield was not significantly different between‘Cedis＇ and‘Country＇. The harvest rate of‘Cedis＇ reaching the high level of cut-flower quality was significantly higher than that of‘Country＇. However,‘Country＇was higher in the fresh weight and stem length relatively. The accumulation amount of nitrogen and potassium in‘Cedis＇ was evidently higher than that of ‘Country＇with increase of 10.80% and 35.03%,respectively,while that of phosphorus was not different between two chrysanthemum apparently. The total amount of‘Cedis＇ nutrients was K,N,P in decreasing order,and that of‘Country＇nutrients was P,K,N in increasing order. The requirement of chrysanthemum on nutrients increased to the highest level when chrysanthemum was transplanted after 30–45 d（the stem growth stage–the flower bud differentiation stage）.
