This application discloses a method for inhibiting
excessive growth of shoots
sprouting below the fracture surface of large branches of *Walnut yangbiense* and promoting fruit production, comprising the following steps: 1) After sawing off large branches of *Walnut yangbiense*, a sealing gel containing
carbendazim and
paclobutrazol is applied to the
cut surface; 2) Below the fracture surface, a
branch segment with a length of 45–55 cm is selected, and multiple incisions are made on the segment, extending to the
xylem, with the incisions evenly distributed on the surface of the selected segment; 3) 190–210 g / tree of
paclobutrazol, 1.5–2.5 kg / tree of NPK compound
fertilizer, and 25–35 g / tree of
rare earth powder are applied to the soil around the base of the
trunk, followed by rotary
tillage and soil covering. After implementation of this method, the new shoots
sprouting below the fracture surface grow only 12–16 cm per year, far less than the
annual growth length of the control treatments, demonstrating a good effect in controlling
excessive growth of new shoots.
