摘　　要：在玉米高密度种植条件下,在其他管理措施和施肥量相同的情况下,采用水肥一体化施肥滴灌技术,夏玉米在生育关键期表现出地上部干物质质量明显提高,生物量增加,为夏玉米提质增产增效奠定基础。水肥一体化滴灌技术提升了玉米产量,增加了收入。滴灌施肥与常规施肥相比,亩节本增效12.54元—126.26元,其中最高亩增效益1161.47元,亩节本增效126.26元。Under high-density planting the use of drip irrigation with integrated watering and fertilization technology increased dry matter mass of above-ground part of summer corn significantly during critical growth period under the same other management measures and fertilizer application amount(pure conversion),which could increase biomass and lay a foundation for improving the quality,yield and efficiency of summer corn cultivation.Drip irrigation integrated watering and fertilization technology improved corn yield and increased income.Compared with conventional fertilization,drip irrigation fertilization could save costs and increase efficiency by 12.54 yuan to 126.26 yuan per mu,in which a significant efficiency of 1161.47 yuan per-mu and of 126.26 yuan cost saving were achieved.
