This paper describes the integrated management mode of irrigation and drainage in four districts of Huaibei Plain in Anhui Province.The governance models in the northern part of Huaibei are as follows: (1) The shallow drainage ditch should be shallow drainage ditch; (2) (3) High efficient water-saving irrigation technology (4) Choose drought-resistant and high-yielding grain crops and cash crops The mode of dryland zoning in the middle Hejian Plain is: (1) moderate drainage, (2) (1) Give full play to the integrated water-saving effect of drainage system; (2) Water-saving irrigation engineering technology. The management mode of vegetables and efficient cash crops in suburbs of cities and towns is as follows: (1) micro-irrigation technology; (2) low-pressure pipeline supporting hand-held hose irrigation; (3) fixed sprinkler irrigation.
