The invention discloses an electric topping and sprouting inhibition shear. The electric topping and sprouting inhibition shear comprises a handle outer casing, a cutting mechanism, a pesticide spraying mechanism and a control mechanism, wherein the cutting mechanism is arranged on the handle outer casing; the pesticide spraying mechanism is arranged on the cutting mechanism; the control mechanism is used for controlling the cutting mechanism and the pesticide spraying mechanism to work; the cutting mechanism comprises a slide rail, a slide block and a driving assembly, the slide rail is arranged in the handle outer casing, the slide block is in sliding fit with the slide rail, and the driving assembly is used for driving the slide block to do reciprocating movement; the front end of the slide rail extends out of the handle outer casing, and is provided with a first blade; a second blade is arranged on the slide block and is matched with the first blade to shear. By adopting the structure, the electric topping and sprouting inhibition shear has the advantages that the mechanical topping of tobacco plants is realized, the spraying amount of sprouting inhibition agent is accurate and controllable, the pesticide residue amount can be effectively controlled, and the quality of subsequent tobacco product is improved; the size is small, the hand holding of an operator is convenient, the electric topping and sprouting inhibition shear is especially suitable for mountain and hill areas, the operation is simple, convenient and rapid, the labor intensity of operators is effectively decreased, and the production cost is reduced.
