Detailed Explanation of Persimmon Tree Grafting Techniques, Methods and Steps
Persimmon is a relatively common fruit tree that friends in rural areas often see; basically every household grows one or two, and when the persimmons ripen, the fiery red fruits hang on the tree, looking very beautiful. When growing persimmons, in order to cultivate strong seedlings and increase yield, grafting techniques are often used. So how should persimmons be grafted? Let's learn about it together.
1. Grafting Time
There are many grafting methods for persimmon, and different grafting methods have different grafting times. Cleft grafting is suitable in March-April when the buds have already begun to sprout; at this time the rootstock sap begins to flow, and the scion is in the dormant bud-breaking stage, which helps improve the grafting survival rate. Bud grafting has two suitable grafting times each year: one at the transition between spring and summer, in May when persimmons bloom; the second at the transition between summer and autumn, preferably in August when the autumn shoots begin to stop growing.
2. Cleft Grafting Method
Cleft grafting uses perennial, robustly growing, well-developed vegetative branches or fruiting branches as scions. It can be further divided into cleft grafting, bark grafting, and so on. Cleft grafting is suitable when the rootstock is thick and strong. At 5-10 cm above the ground on the rootstock, choose a smooth, straight spot and cut it off, then use a knife to make a slit 3 cm deep in the middle. Cut the lower end of the scion into a wedge shape, requiring the scion to carry 2-3 plump buds, and insert it into the slit, aligning the cambium layers of both. Bark grafting is generally carried out after the rootstock bark slips. Choose a smooth spot on the rootstock bark and cut it off, make a longitudinal cut through the bark on one side down to the xylem, twist the knife left and right to make part of the bark lift, cut the scion into a horse-ear shape, and insert it under the bark.
3. Bud Grafting Method
Bud grafting uses plump buds from one-year-old branches that have not yet sprouted as grafting buds. The commonly used types are T-shaped and H-shaped. For the T-shaped method, make a T-shaped cut 3-5 cm above the ground on the rootstock, reaching deep to the xylem, then take a shield-shaped bud piece about 2 cm long and 0.6 cm wide from the scion and insert it. For the H-shaped method, cut an H-shaped slit about 2 cm long and 1.5 cm wide on a smooth part of the rootstock, cut a rectangular bud piece from the scion equal in length to the rootstock cut, insert it into the cut, then wrap the bud piece with rootstock bark, remove excess rootstock bark, expose the bud, and tie it with plastic film.
4. Precautions
The persimmon plant contains an alkaline substance called tannin, which oxidizes very easily when exposed to oxygen, causing wounds to turn yellow and black. Therefore, grafting must be performed by experienced people. To avoid wound oxidation, proper handling must be done to prevent grafting failure.
