[0002] Tobacco is an annual herb of the genus Nicotiana in the Solanaceae family. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, gradually pointed at the apex, narrowed at the base into an ear-shaped semi-amplexicaul shape, and the petioles are not obvious or wing-shaped.
[0003] When tobacco is planted, there is a girdling device for girdling the tobacco plants. In order to reduce the absorption of nutrients by the tobacco plants, the stems of the tobacco plants are girdled. Girdling refers to the practice of surrounding the branches of the plant and peeling off a certain width of bark to reduce the absorption of nutrients. At the same time, it can disinfect and avoid cross infection.
[0004] However, when girdling the tobacco plants, the staff needs to hold the girdling device to gird the tobacco plants. If the staff uses too much force, the depth of the girdling of the tobacco plants will be deeper. If the staff uses too little force, the depth of the girdling of the tobacco plants will be shallower. As a result, the staff cannot control the girdling force well during girdling, thus affecting the girdling effect. Utility Model Content
