The invention relates to an electric quantitative annular fertilizing device for flue-cured tobacco transplanting, and belongs to the field of agricultural mechanical equipment. A quantifying shaft of the electric quantitative annular fertilizing device is driven by a micro motor to cooperate with a quantifying base to quantitatively distribute granular chemical fertilizer in a fertilizer bucket; in different growth periods of tobacco seedlings, the fertilizing amount can be adjusted through a quantitative adjusting sheet, the quantitatively distributed granular chemical fertilizer enters a conical scattering disc along a feeding pipe, the granular chemical fertilizer is annularly scattered around hole pond plantlets through the conical scattering disc under the action of rotation, an annular fertilization function is achieved, it is guaranteed that the root systems of the tobacco seedlings can grow downwards, meanwhile, electric quantitative fertilization on each tobacco seedling is achieved, the human labor intensity is greatly reduced, and fertilization efficiency is improved. In the fertilization process, the conical scattering disc can be covered with a conical cover, and it is avoided that the chemical fertilizer is scattered all around to cause chemical fertilizer waste. The electric quantitative annular fertilizing device is simple in structure, convenient to carry and high in practicality, and the fertilization efficiency is effectively improved.
