摘　　要：以河南圆粒油莎豆为试材,在覆膜滴灌条件下,研究了氮磷钾肥的配施对油莎豆产量及品质的影响。结果表明:T7处理(N 67.5kg/hm2,P2O594.5kg/hm2,K2O 118.125kg/hm2)、T3处理(N 67.5kg/hm2,P2O594.5kg/hm2,K2O 78.75kg/hm2)的肥料配施条件下适合于油莎豆的高产,产量分别达到12 649.5kg/hm2和11 449.5kg/hm2。T7和T3处理亦能极显著地提高油莎豆的品质,若综合考虑优质、高产、成本投入及环境保护等因素,以T3肥料配施较优。Taking Henan Cyperus esculentus as material, the effects of N,P, K combined application on yield and quality of Cyperus esculentus under plastic mulched drip irrigation were studied. The results showed that the best amount of N,P, K fertilizer applied for Cyperus esculentus with maximum yield was T3（N 67.5 kg/hm^2 , P2O5 94. 5 kg/hm^2 , K20 78. 75 kg/hm^2 ）, T7 （N 67.5 kg/hm^2 , P2 O594. 5 kg/hm^2 ,K20 118. 125 kg/hm^2）,with the yield reaching 11 449. 5 kg/hm^2 and 12 649. 5 kg/hm^2. If considering high quality,high yield,cost of inputs and environmental rotection,the better fertilizer quantity was T3.
