Abstract:: 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/hm²，P₂O₅94.5 kg/hm²，K₂O 78.75 kg/hm²),T7(N 67.5 kg/hm²，P₂O₅?94.5 kg/hm²，K₂O 118.125 kg/hm²),with the yield reaching 11 449.5 kg/hm² and 12 649.5 kg/hm².If considering high quality，high yield，cost of inputs and environmental rotection，the better fertilizer quantity was T3.
