摘　　要：为推动江苏响水地区露地青花菜高效、丰产和可持续发展,综合考虑青花菜种植规模、地理地形、种植面积和水源概况等,通过计算灌溉管网系统各项参数,优化设计了基于沟渠水源水肥一体化管网布局,并根据当地灌溉分区规划和灌溉施肥制度原则,构建了1套合理的水肥综合管理系统,可有效地提高劳动生产效率及水肥利用效率。相比传统农田灌溉施肥节水30%以上,节肥25%以上,增产15%左右,减少劳动投入80%,降低了人工管理费用,大大减少了灌溉不均匀的现象。In order to promote the efficient,productive and sustainable development of broccoli planted in open field in Xiangshui district of Jiangsu province,the layout of the integrated pipe network based on ditch water and fertilizer was optimized by comprehensively considering the planting scale,geographical topography,planting area and water source profile of broccoli,calculates various parameters of the irrigation pipe network system.Besides,a reasonable comprehensive water and fertilizer management system was constructed according to the local irrigation zoning planning and irrigation and fertilizer system principles so as to effectively improve the labor production efficiency and water and fertilizer utilization efficiency.Compared to traditional farmland irrigation and fertilization,it saved water by more than 30% and fertilizer by 25%,increased yield by about 15%,reduced labor input by 80%,reduced labor management costs and greatly reduced the phenomenon of uneven irrigation.
