摘    要:试验研究结果表明:高油玉米、高淀粉玉米和高蛋白玉米对氮磷钾的敏感顺序均为氮>钾>磷。在目前的肥料施用量及玉米和肥料价格情况下,高油玉米氮磷钾配施获得的经济效益为341元/hm2,磷钾配施的经济效益为120元/hm2,氮钾配施和氮磷配施的效益均为负值;高淀粉玉米施肥效益为负值;高蛋白玉米氮磷钾配施可获得609元/hm2的效益。氮磷配施、氮钾配施及磷钾配施的效益均为负值。氮磷钾配施对高蛋白玉米的增产效益最大,对高淀粉玉米的增产效益最小。

关 键 词:优质玉米  营养  产量  效益

Abstract:The experimental results showed that the order of high oil,high starch and high protein maize response to N,P and K were all N > K > P.Under the condition of the fertilizer application rates and the price of maize and fertilizer at present,the combined application of N,P and K for high oil maize can get the benefit of 341 yuan/ha,the combined application of P and K for high-oil maize can get the benefit of 120 yuan/ha,the combined application of N and K as well as the combined application of N and P all got the negative benefit.The fertilization for high starch all got the negative benefit.The combined application of N,P and K for high protein maize can get the benefit of 609 yuan/ha,the combined application for the any two of N,P and K were all got the negative benefit.The combined application of N,P and K got the highest and the lowest benefit for high protein maize and for high starch respectively.
Keywords:High quality maize  Application  Yield  Benefit
