Grafting technology of pepper tree

The most widely used methods of grafting Zanthoxylum bungeanum trees are: bud grafting, which uses buds as scions (buds); branch grafting, which uses a branch with one or several buds as scions. Branch grafting includes cleft grafting, cut grafting, etc.

1. Cleft grafting

Cleft grafting is suitable for thicker rootstocks. When grafting, choose 2-4 year old seedlings, saw them off at a relatively smooth part, and then use a grafting knife to flatten the cross section. Then take the scion, cut a knife on each side to make the lower end into a wedge shape, cut it with 2-3 buds, and then use a wooden wedge to prop open the cut of the rootstock and insert the scion.

2. Cutting

For grafting, choose a place with thick, smooth cortex and smooth texture, cut off the cross section of the rootstock, make an oblique cut on the back of the lower bud of the scion, and then insert the scion into the cut of the rootstock so that the cambium on both sides of the rootstock and scion are aligned and close.
