What should we pay attention to in the best grafting method of Lagerstroemia indica?

1. Select the part with full leaf buds in the middle of the branch and cut it into 3-5 cm long, with 2-3 buds as the scion. Cut the long section of1.5-2cm downward on the smooth surface of the scion, and cut the short section of 0.7-1.2cm on the reverse side. Cut off the head at the appropriate part of the rhizome with a hacksaw or branches. On the smooth and flat side of the rootstock, use a cutting knife to obliquely cut a knife on the shoulder of the cutting surface to expose the cambium, aim at the inside of the cambium with slightly exposed xylem, and cut a cut of about 2 cm vertically downward. The terminal bud of the scion is on the same side as the long section, facing the long section and facing the rootstock incision, and the scion is evenly inserted into the rootstock incision. When operating, the scion should be in a line called "Bailu", which is beneficial to survival.

2. The cambium of scion and rootstock should be aligned or at least aligned to one side, and cutting scion and rootstock must be completed with one knife, otherwise the complete combination of scion and rootstock cannot be guaranteed, thus affecting the survival rate.

3. Then use a 3cm× 60cm long plastic strip to tie it up from top to bottom. Be careful not to rub the seams when binding. Cover the cross section of the rootstock tightly, seal the incision to prevent rainwater from infiltrating, and finally tie it tightly and fix it.
