The utility model discloses a positioner for the accurate transplantation planting distance of flue-cured tobaccos. The positioner comprises a central bearing, sleeve connecting rods, a rolling ring, an operation handle and positioning needles; the circumference of the rolling ring, the distance between the central bearing and the rolling ring, and the distance between every two adjacent positioning needles can be adjusted according to the actual planting distance through a round rod sleeve screw, inner supporting sleeve screws, outer supporting sleeve screws and positioning needle screws, so that the distance between every two adjacent positioning needles can be adjusted at the distance of 50, 51, 52, 53, 54 or 55 cm. Therefore, the positioner has the advantages that the accuracy in the planting distance of a flue-cured tobaccos field can be greatly improved, the planting distance for transplantation of the flue-cured tobaccos is accurately positioned, the planting density of planted tobaccos plants in the unit area is reasonably maintained, the tobaccos leaf production quality and working efficiency are improved, the uniformity in the planting distance is ensured, the labor intensity is reduced, and convenience for manual operation and good simplicity and practicability are realized.
