Early grafting of Waxberry is more beneficial to the grafting technique of Waxberry in Spring

The scion of red bayberry is 2-3 years old. The stem is 0.8-1.5cm thick and 5-6cm long, depending on the size of the rootstock. The key to affecting the survival rate of grafted bayberry is to pay attention to windproof after grafting, set up pillars in time, fix new shoots and prevent them from being broken by the wind.

Red bayberry grafting

1. Scion collection:

The scion of Waxberry should be 2-3 years old at the periphery of the crown or at the top, and the robust branches of 0.5-1cm in diameter, and the spring or summer shoots of last year which are fully mature are also fine. After picking the scion, immediately cut off the leaf bark, twigs, and do a good job of moisturizing. When grafting on the spot, the required scion is grafted with picking. Long-distance collection, to take good care of, can be clean, moist fine sand layer-by-layer burial, pick up with pick-up.

2. Selection of rootstocks:

The seed trees of wild bayberry seeds are better, after grafting, they heal well, and have strong resistance and adaptability. In terms of tree age, it is better to choose the seedlings cultured for 2-3 years, and the tree age is within 15 years.

3. Grafting time:

The grafting of red bayberry is generally carried out before sprouting in spring, and early grafting is more advantageous. From late February to early March, choose sunny days with high temperatures. If it is too late, the bleeding will affect survival.

4. Grafting method:

1. Cutting method: red bayberry grafting is usually horseshoe-shaped, also known as horseshoe-shaped, long spike, full-coated high grafting. When grafting, the scion should be longer than that of the grafted seedling, which is usually 10 cm. The length of the cutting surface on the scion should be at least 1.5-2cm, preferably 3cm long, and smooth. The position of the scion on the rootstock should consider the shape of the tree in the future, which should be developed and sunny. To reach this point, it should be reserved as trunk, main branch and secondary main branch, which requires oblique outward growth and moderate growth, so as to avoid grafting on overstrong rootstocks and form the main structure. In order to avoid the baldness of the backbone branches and increase the fruiting part, the scions were arranged in the empty part and cultured as auxiliary branches to increase the fruiting. The distance between scions is more than 50 cm, so as not to cause too many branches and cause depression. The greater the angle between the bud and the central leader, the better the light, and the better the result. After grafting, the wound was bandaged with thin film. After survival, the new scion shoots emerge from the membrane seams.

2. High grafting method: the high grafting height of red bayberry and the number of scions borrowed should be suitable to the age of rootstock. For example, a 3-4-year-old tree is grafted high on the main branch, with a height of 40m ~ 60cm and a number of 3m ~ 4m scions. The 5-7-year-old tree is high grafted on the main branch, the secondary main branch and the lateral branch, the height is 80 Mel 120 cm, the number of scions is 10 mi 15, the diameter of the interface is more than 3 cm, and one interface is connected with 1 Mel and 2 scions. 8. The 12-year-old trees were grafted at 150 cm in height, and the number of scions was 15. 20 scions. Side regrafting was carried out in the empty backbone branches to increase the fruit branches. 13-20 years old, with high grafting at 1.8m / 2.5m and 30 scions with 25m / m. Lateral summer grafting was carried out in the empty backbone branches to increase fruit branches. More than 20 years of red bayberry trees, decline, vitality decline, it is not easy to survive after grafting, even if survive, poor growth, irregular growth among trees. Before the high grafting, the branches were renewed, the main branches and secondary main branches were sawed off at 1.4m, then the new branches were cut off, and then the branches with sturdy, good growth and good position were selected, and the high grafting was carried out the next year, and the rest of the over-dense branches were evacuated properly.
