The invention discloses a plant snow removal method, in particular to a method for removing accumulated snow on a plant through a plant snow removal device which moves in a mechanical intermittent mode and hauls the flexible part of the trunk of the plant in a reciprocating mode through a hauling rope. The plant snow removal device comprises the hauling rope, a hauling device and a controller. One end of the hauling rope is connected with the flexible part of the trunk of the plant, the other end of the hauling rope is connected with the hauling device, the controller controls an electromotor to intermittently run to drive a hauling force generation mechanism to move, the hauling force generation mechanism drives the hauling rope to move, and the hauling rope drives the flexible part of the trunk of the plant to generate reciprocating swings, so that accumulated snow on leaf crowns of the plant are made to drop, damage of the pressure of the accumulated snow to the plant is eliminated, through plant snow removal, adaptability of the plant to environments is improved, plants growing in the south extend to the north, damage to the plants is reduced, economic benefits are increased for farmers, the method is suitable for plants growing in multiple environments and being planted according to multiple methods, and practicability is high.
