The method is simple and the effect of controlling the flower is obvious. However, due to the poor healing of the wounds after girdling, it often appears that the curative effect is not obvious due to premature healing or the phenomenon of dead trees (branches) is even impaired due to the late healing. In recent years, based on the principle of girdling, the fruit farmer in Jiaonan, Shandong Province has found two alternatives to girdling in production practice to make up for the shortcomings of girdling.
