How to graft grape seedlings? How many years?

Firstly, the scion was cut, and 1-2 buds were retained on the scion, and then at the bottom of the lower bud of the scion, at the distance of 0.5-0.8cm from the bud, the slant of 3cm was cut on both sides, and the cilantro was smooth and wedge-shaped, the scion was thinner on one side and thicker on the other side, and then the upper 2-2.5cm of the bud was cut into clean water, and when the cutting side of the stock was inserted, the thick side of the scion was facing outward and the thin side was facing inward. Generally grafted grape seedlings will bear fruit in the second year if they are properly managed.

First, how to graft grape seedlings

The main results are as follows: 1. Generally grape seedlings are grafted by split grafting, first cutting the scion and keeping 1-2 buds on the scion, then at the lower part of the scion at the bottom of the bud 0.5-0.8cm away from the bud, a slope about 3cm length is cut on both sides, the cilantro is smooth and wedge-shaped, and the scion is thinner on one side and thicker on the other, which is beneficial to the tight grafting after being inserted into the rootstock.

2. After cutting the lower part of the scion, it is necessary to cut the upper 2-2.5cm of the bud, then put it in water or contain it in the mouth. When inserting the cutting seam of the rootstock, the thick side of the cutting surface of the scion faces outward and the thin side faces inward, which can promote the close combination of the rootstock, and pay attention to the alignment of the cambium of the rootstock and the scion, and slightly "expose" 1-2mm, which is conducive to wound healing in the later stage.

3. After grafting, you need to use a wide 1cm plastic strip, winding upward from the bottom of the interface of the rootstock to the upper incision of the scion. The port of the plastic strip needs to tie a living knot around the bottom of the joint to avoid moisture loss at the interface, and the young shoots that grow after survival are protected from sunburn. Generally, the interface can be wrapped with leaves growing near the joint on the rootstock.

II. Management of grape seedlings after grafting

The main results are as follows: 1. After grafting the grape seedlings, it is necessary to irrigate the grape seedlings with fine water in time, which is beneficial to maintain sufficient soil moisture. Check the survival rate after 7 days. If it is found that the grafted shoots are bright green or the petioles that rely on the buds fall as soon as they touch, it shows that the grape seedlings have survived. If the grape buds turn brown and the petioles are dry and not easy to fall off, it shows that the grafting did not survive and needs to be regrafted in time.

2. For the surviving plants, when the new shoots grow to 60-70cm, they need to pick the heart for the first time, release the plastic strip tied on the interface in time, and tie it on the shelf at the same time, which is beneficial to promote the healthy growth of the new shoots, and the management in the later stage is the same as that of ordinary seedlings.

3. Grape seedlings grafted for several years bear fruit

Generally grafted grape seedlings, if properly managed in the first year and sufficient fertilizer and water, will form flower buds, and will bear fruit in the second year. If the grape seedlings are not well managed, it is possible to postpone the fruiting time. At the same time, the grafted grape seedlings are different in fruiting time.

4. How much is the grape seedling grape grape?

It is about 4.2 yuan per grape seedling in spring light, 4.3 yuan in giant rose grape seedling, 4.3 yuan in sweet sapphire grape seedling, 4.7 yuan in black grape seedling, 4 yuan in honey grape seedling, 4.7 yuan in Karen grape seedling and 4.6 yuan in green grape seedling.
