The invention relates to a water and fertilizer integrated drip irrigation method for flue-cured tobacco and belongs to the technical field of tobacco cultivation. The water and fertilizer integrated drip irrigation method for flue-cured tobacco comprises the following steps: (1) after ridging and pond digging, arranging branch pipes in waist ditches which are dug perpendicular to tobacco ridges; (2) arranging non-porous drip irrigation belts along the tobacco ridges, wherein the water inlet ends of the non-porous drip irrigation belts are communicated with the pipe walls of the branch pipes; (3) punching holes in the portions, corresponding to the position of a tobacco pond, of the non-porous drip irrigation belts; and (4) after the tobacco plants are transplanted to the tobacco pond, carrying out 5 times of drip fertilization or 9 times of drip fertilization. According to the method, the non-porous drip irrigation belts are adopted to accurately open holes according to actual needs, it is guaranteed that flue-cured tobacco transplanting is not affected while the tobacco pond is irrigated, the utilization efficiency of irrigation water is improved, fertilizer is applied according to needs in batches, the nitrogen fertilizer nutrient requirement rule of flue-cured tobacco with less nitrogen fertilizer in the early period and more nitrogen fertilizer in the middle period is met, the nitrogen fertilizer utilization efficiency is greatly improved, and then the yield and quality of tobacco leaves are improved.
