Effects of N,P and K ratio on the growth and development of cut chrysanthemum ‘Jinba’

    Corresponding author: FANG Wei-min

Abstract: To determine the effects of N,P,K nutrients on the growth and development of cut chrysanthemum ‘Jinba’(Dendramthema × grandiflorum ‘Jinba’) and obtain the optimum formula,experiment with orthogonal experimental design with three factors including N,P,K nutrients at three levels was conducted. The results indicated that under the condition of this experiment,N was the most important factor influencing the growth and development,and stem diameter,leaves area,flower diameter,length of petal,growth days of flower bud break,plant weight and length of root among three levels was significant(P<0.05). The effects of P on stem diameter,length of flower neck and growth days of flower bud broke was significant. The effects of K on length of flower neck,growth days of flower bud broke,leaves fresh mass and stem fresh mass was significant. The optimum fertilization level of N,P,K was N ∶ P ∶ K= 14.3 ∶ 2.0 ∶ 8.0 during vegetative growth stage and N ∶ P ∶ K = 7.1 ∶ 4.0 ∶ 12.0 during reproduction stage.[Ch,4 tab. 18 ref.]
