Abstract: 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）.
