摘　　要：针对冀西北地区水资源匮乏和化肥不合理施用问题,进行了春玉米膜下滴灌水肥一体化技术试验。结果表明,与农户传统水肥管理措施相比,膜下滴灌水肥一体化技术可明显增加春玉米产量,提高春玉米的肥料偏生产力;膜下滴灌水肥一体化技术虽增加了地膜、滴灌设备的费用,但可实现播种、施肥、覆膜、铺设滴灌带、喷施除草剂等多道工序一次性完成,可节省用工费和水电费。综合分析结果表明,春玉米膜下滴灌水肥一体化技术可提高农户的经济效益,在冀西北地区有良好的推广应用前景。Study on integrated water and fertilizer management with drip irrigation and film mulch for spring maize was car-ried out to solve the problems of lack of water resources and unreasonable application of fertilizer in northwest Hebei province. The results showed that yield of spring maize and partial factor productivity（PFP） under integrated water and fertil-izer management with drip irrigation and film mulch were higher than those under traditional water and fertilization manage-ment. Integrated water and fertilizer management with drip irrigation and film mulch increased the cost of plastic film and drip irrigation equipment, but this practice could save cost of labor and water through simultaneous realization of sowing, fertilization, mulching, laying drip irrigation, spraying herbicides and other processes. In short, integrated water and fertilizer management with drip irrigation and film mulch for spring maize could improve the economic benefit of farmer, and had good prospect of application and extension.
