Zusammenfassung:	The invention provides a rice field nutrient regulation and control method and device. The method comprises the following steps: determining the nutrient amount brought by irrigation according to the nutrient concentration and irrigation water amount in irrigation water in the previous growth stage of rice, and determining the nutrient amount brought by rainfall according to the nutrient concentration and rainfall in rainwater in the previous growth stage of rice; according to the nutrient concentration and the displacement in the drained water of the previous growth stage of the rice, determining the nutrient content of the drained water belt, and according to the nutrient concentration and the leaching water volume of the leaching water of the previous growth stage of the rice, determining the nutrient content of the leaching belt; according to the amount of nutrient brought by irrigation, the amount of nutrient brought by rainfall, the amount of nutrient taken away by drainage and the amount of nutrient ta
