摘　　要：水肥一体化是发展现代农业的关键技术之一,以明显的节水增产效应使其大面积推广应用成为可能,水肥一体化技术和常规漫灌进行试验比较,发现前者节水率达19.9%,增产8.6%～14.6%。但是由于受到技术、经济等的限制,目前水肥一体化设备和推广应用中还存在问题,本文就存在的问题进行了阐述并提出相应的对策,为我国发展现代农业提供支撑。Integrative water and fertilizer technology is one of the key technologies in development of modern agriculture, its significant water saving and yield increasing effects make its large-scale application possible. Compared with traditional flooding irrigation, it could save water by 19.9% and increase yield by 8.6%-14.6%, but there were still some problems in its widespread application due to economic and technological limitations. The existing problems and corresponding countermeasures are elaborated aiming to provide support for modern agricultural development of our country.
