摘　　要：采用氮、磷、钾不同配比施肥,对切花月季卡罗拉的株高、叶片数、最大叶面积、盛花期开花数、最大花冠径、切花枝长度、白粉病发病率、脯氨酸、可溶性糖含量等指标进行测定,结果表明供试的12种氮磷钾配比处理中,处理輥輰訛生长最好,抗白粉病能力最强,N∶P2O5∶K2O的施入量为0.108、0.010、0.057 kg/m2,比例为1∶0.93∶0.53。Through the different N,P and K fertilization experiment,the indexes of stem height,leaf area,leaf number,blossom number,Maximum corolla diameter,branch length,incidence of powdery mildew,contents of praline and soluble sugar were analyzed.The results showed that among the 12 kinds of N,P and K treatments,the cut rose treated with T was of best growth and resistant to powdery mildew,with application of N,P2O5 and K2O of 0.108、0.010、0.057 kg/m2 respectively and the ratios was of 1∶0.93∶0.53.
