摘　　要：以蝴蝶兰栽培品种‘粉红豹’和‘绿如意’为试材,研究不同氮(N)、磷(P)、钾(K)比例的营养液处理对成株期蝴蝶兰开花的影响。结果表明,与商品用花期肥料“花多多2号”(N:P:K=10:30:20)对照相比,适当提高P元素比例的营养液1号(N:P:K=10:40:20)和适当降低N元素比例的营养液3号(N:P:K=5:30:20)均能显著缩短蝴蝶兰花梗的平均萌发时间;且营养液3号在促进植株花梗伸长生长,增加开花数量,缩短开花时间,提高开花品质等方面的综合表现较佳。Effects of different ratio of nitrogen(N),phosphorus(P),and potassium(K)nutrient solution treatments on flowering characteristics of mature plants of Phalaenopsis cultivars‘Fen Hongbao’and‘LüRuyi’were studied.The results showed that compared with control nutrient solution(N:P:K=10:30:20),appropriately increasing P element proportion(No.1 nutrient solution,N:P:K=10:40:20)and reducing N element proportion(No.3 nutrient solution,N:P:K=5:30:20)significantly shortened the average initiation and outgrowth time of flower peduncle.In addition,the comprehensive performance of No.3 nutrient solution was better in promoting flower peduncle elongation growth,increasing the floral number,shortening the flowering time and improving flowering quality.
