The invention discloses a pepper high-
branch grafting method which comprises the following steps: firstly, sawing off the part, 20-60cm away from the ground, of a stock, flattening the cross section, and removing pepper thorns within 10cm around the cross section; then, obliquely
cutting a
skin layer on one side of the section to reach the
xylem; the scion is firstly obliquely
cut and then vertically
cut from the opposite side to the
xylem. Then inserting the scion into the stock, aligning the
cambium and slightly exposing the upper end of the scion; on the premise that the scion is not touched, a special film belt for
grafting is used for binding the connector from bottom to top, and a
bud on one side of the base of the scion is reserved. Besides, the portion, 5-10 cm below the connecting point, of the stock is coated with a layer of dry-wet adjusting material through a film belt special for
grafting, the film belt is composed of
zeolite with the particle size of 3-4 mm and
montmorillonite, and holes with the spacing of 3-5 cm and the
diameter of 1-2 mm are formed in the film belt so that the proper
humidity of the connecting point can be kept. The method ensures that the interface is moist, improves the grafting
survival rate, promotes healthy growth of the Chinese prickly ash tree, realizes variety improvement, and provides
technical support for the Chinese prickly ash industry.
