The grafting method of pomegranate is as follows:
1, firstly, smooth the cross section of the rootstock with a knife, and then split the rootstock vertically with a cleaver, with a depth of 4cm~5cm, equal to or slightly longer than the scion surface.
2. When the scion is grafted, it should be cut into smooth slopes from both sides of the lower bud, so that the outside of the scion is slightly thicker than the inside and is wedge-shaped.
3. Leave 2~4 knots for each scion, and cut the surface by 3cm~4cm. After cutting the scion, pry open the split seam with the back of the knife and insert the scion, so that the scion and rootstock cambium are aligned when inserting. One branch can insert 1~2 scions. If the rootstock is thick, it can also be cut into a cross-shaped incision and inserted with 3~4 scions. After the connection, use a plastic film tape with a width of 2 cm to 3 cm to tie it tightly from the lower end of the joint until the scion is tied tightly with the rootstock interface.
4. Hold the pomegranate well and stably with a bracket to ensure normal growth.
5. Pay attention to the situation after grafting.
Extended data:
Grafting is a kind of vegetative reproduction in asexual reproduction. When grafting, the scion should be closely combined with the cambium of rootstock to ensure the survival of the scion. Grafted branches or buds are called scions; Grafted plants are called roots or edible wood. Generally, seedlings with 2 ~ 4 buds are selected as scions, which become the upper part or top of the plant after grafting, and rootstocks become the roots of the plant after grafting.
When grafting, the cambium of the two injured surfaces are close together and tied together. As a result, due to cell proliferation, they heal each other and become a whole connected with vascular tissue. This is the principle of grafting.
The new plants propagated by grafting can not only keep the excellent characters of the mother plant, but also make use of the excellent characteristics of the rootstock (stress resistance, adaptability, early fruiting, etc.). ).
