- 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 67.5 kg/hm2,P2O5 94.5 kg/hm2,K2O 118.125 kg/hm2)、T3处理(N 67.5 kg/hm2,P2O5 94.5 kg/hm2,K2O 78.75 kg/hm2)的肥料配施条件下适合于油莎豆的高产,产量分别达到12 649.5 kg/hm2和11 449.5 kg/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。
- 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.
