Grafting method of pomegranate tree:
1. Preparation before grafting
Grafting techniques of pomegranate trees: 1. Prepare tools before grafting. Generally, knives and saws are faster. If the knife is not sharp, it will not only affect the operation and slow down the grafting speed, but also reduce the contact surface between the scion and the rootstock due to uneven incision, resulting in wound necrosis. In addition, prepare benches and plastic film belts. Secondly, when the grafting is changed, the crown of the rootstock should be plastered. Generally, the crown after plastering should be reduced to 1/3 before plastering. You can choose 1~3 trunks, and leave 1~2 lateral branch plasters on each trunk, and the incision diameter is about 5cm.
2. Grafting time
The grafting time is from mid-March to mid-April, when the survival rate is high.
3. Grafting method of pomegranate tree
Grafting methods in pomegranate production include split grafting, cut grafting and subcutaneous grafting, among which split grafting is used more.
The splitting method is as follows: firstly, the cut surface of the rootstock is polished smooth with a knife, and then the rootstock is split vertically with a splitting knife, and the depth is 4cm~5cm, which is equal to or slightly longer than the surface of the scion. When the scion is grafted, it should be cut into smooth inclined planes from both sides of the lower bud, so that the outside of the scion is slightly thicker than the inside and is wedge-shaped. 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. If a plastic film bag can be placed at each joint of the rootstock and the lower end is tied tightly, the survival rate can be improved.
