The invention relates to a combined operation dispatching method for direct replenishment with a single water replenishment pump station and a single reservoir under condition of deficit irrigation. Taking maximum annual crop yield in an intake area as an objective function, reservoir water supply stages divided by the crop growth stage as stage variables, and reservoir water supply at each stage as decision variable, and under constraints of total annual available water supply of the reservoir-water replenishment pump station, staged available water supply of the water replenishment pump station and reservoir dispatching rules and reservoir capacity under the condition of deficit irrigation, an optimal water resource allocation module for direct replenishment with a single pump station-single reservoir system is built, a one-dimensional dynamic programming method is adopted for solution, the maximum annual crop yield under the condition of deficit irrigation as well as corresponding optimal water supply at a
