How do you graft trees? Tree grafting method tutorial

Here's how: cut the graft interface. Use a grafting knife to cut a centimeter parallel to the rootstock on the upper and lower sides of the rootstock saw edge, deep into the xylem, and twist the knife edge slightly towards the xylem.

Cut the scion. The length of the scion should be 5 6 cm, the upper end should have 1 2 full (germinating) axillary buds, and the lower end should be cut into a fracture of about 45 degrees with the scion, and on the front and back of the lower fracture. The axillary bud part of the scion needs to be covered with a single layer of film.

Take osmanthus grafting as an example:

1. Dealing with scion: when grafting, it is necessary to choose strong branches that have been lignified to make cuttings, and after selection, the leaves on it should be cut off, leaving one or two pieces, and it is necessary to ensure that there are one or two new shoots, and the bottom is cut into a wedge for later use.

2. Grafted rootstock: cut a cut at the top of the selected rootstock, and the length is similar to the scion wedge. After processing, insert the scion, taking care to align the cambium as much as possible. Do not insert the cut surface completely, leave a little on the outside, and wrap it tightly with plastic wrap at the end.

3. Post-management: After grafting, the entire grafted part should be covered with a plastic bag to keep warm and moisturize. Just make a few openings at the top to breathe.

Under normal circumstances, you can survive in the future, and remove the plastic bag in time. In the later stage, it is necessary to observe diligently, and if you find that there are side buds growing on the rootstock, you should remove them in time, otherwise you will compete for nutrients.

It doesn't matter if you don't graft trees, the little brother teaches you to do "seppuku", the grafting effect is good, and it is worth learning.

T-budding: 1. In order to be able to carry out T-budding, the bark of both trees must be smooth, and this method is usually carried out in the spring. Macro source.

2. Cut a scion. Cut at a centimeter position below the branch and on the bud, to a depth that covers the soft green layer underneath the bark.

3. Make a T-shaped incision in the rootstock. Make a vertical slice of the bark, deep enough to expose about a centimeter of green layer. The shade is about one-third of the way from the rootstock, making a slice that is about as deep horizontally as possible.

4. Use scion. Slide the scion containing the buds underneath the cut you just made on the rootstock, being careful not to bring any dust and bacteria with you. If part of the tarp of the scion sticks out above the T-incision, cut it off so that the parts fit together properly.

5. Tie the scion to the rootstock. Wrap a resilient rubber material (e.g. grafted rubber) around the rootstock to keep the buds in place. Be careful not to squeeze or cover the buds.

6. Remove the tied straps. After about a month, the rubber wrapped around the rootstock may become loose and fall off. If not, you gently take it apart yourself so that the piece doesn't get too tightly tightened.

7. Follow up the condition of the buds. If the bud looks plump and healthy, there's a good chance it's alive. If it's withered, then it's dead and you need to start over.

8. Remove other substances. In the spring of the following year, once the scion begins to germinate, cut centimeters diagonally on the scion that has successfully germinated. Other buds growing under the scion must be removed in order to promote the healthy growth of the grafted scion.

1. Grafting method: the universal grafting method. It is easy to operate, has a high survival rate and heals quickly. When seedlings are raised, attention should be paid to the height of the rootstock and scion seedlings to be roughly the same. If the rootstock is too high, the cutting position can be lowered appropriately to ensure that the roots are flush;

2. Cutting of rootstock seedlings: remove the growth point of the seedlings first. At the same time, 1** leaves are cut off, and this method is called monocotyledon grafting method; Leaving 2** leaves is called the dicotyledon method. The position of the joint port is about 1 cm at the base of the ion leaf is the most suitable;

3. Splitting method: use a blade under the scion cotyledon to cut into a "wedge", and the wedge is 1 cm long. Dig out the rootstock growth point, use the blade from bottom to top along the middle of the hypocotyl and cut the grafting interface 1 cm downward, insert the scion and fix it with a grafting clamp;

When the scion seedling age is l0-12 days, the hypocotyl is 6-7 cm, the rootstock seedling age is 8-10 days, and the embryonic extract length is 5-6 cm, the seedlings can be grafted. At this time, the seedlings have strong vitality, fast healing after grafting, and high survival rate is the best grafting period. l day before seedling, water should be poured once to loosen the soil to reduce root damage.

When the seedlings are raised, they are gently picked up from the bottom layer of the seedling soil, and each time l0-20 plants. When seedlings are raised, attention should be paid to the height of the rootstock and scion seedlings that are roughly the same. If the rootstock is too high, the cutting position can be lowered appropriately to ensure that the roots are flush;

Cutting of rootstock seedlings: remove the growth point of the seedlings first. If 1** leaves are cut off at the same time, this method is called monocotyledon grafting method; Leaving 2** leaves is called the dicotyledon method.

The position of the joint port is about 1 cm at the base of the ion leaf is the most suitable; When the knife is lowered, about 45 from top to bottom. The angle is cut into the hypocotyl of 1 3 a little more, when cutting the joint, it should be cut to a suitable place, and the knife edge should not move back and forth, otherwise it will destroy the conduction tissue of the stem and affect the wound healing, and reduce the survival rate.

Cutting and grafting of scion: cucumber seedlings are thinner and softer than the hypocotyls of pumpkin seedlings, and they should be accurate and ruthless when cutting, and they cannot return to the knife or make the wrong knife. According to the height of the pumpkin seedling, the cutting part is cut at about 1 cm from the hypocotyl ion leaf base, and it is 30 from bottom to top.

Angular cutting knife cut into the cotyl coarse L 2.

When the rootstock and scion are cut, the two are joined together. The method of joining is as follows: hold the pumpkin seedlings in one hand, use the thumb or index finger to separate the joint mouth slightly, and insert the upper cut of the cucumber seedlings into the lower cut of the pumpkin seedlings to make them fit.

When grafting, it is not allowed to move back and forth, and it is inserted at one time, otherwise it is easy to cause dislocation and affect the survival rate. Once jointed, clamp it with grafting clips. In order not to affect the nutrient transport and exchange in the seedlings, the tightness of the grafting clamp should be appropriately adjusted according to the thickness of the embryonic uranium, and the lower edge of the grafting clamp should be leveled with the lower position of the joint, so as to facilitate the cutting of the rhizome of the cucumber seedling after healing.

1. Amputate the tree to be grafted from the middle.

2. Divide the section into two from the middle of the section of the tree tree Zheng branch.

3. Wrap one end of the grafted branch with a black film to prevent water evaporation, and cut out a thin surface at the other end.

4. Insert the thinned end into the tree.

5. Tie the knot with a fine thread to facilitate the contact of the bark.

6. Wrap the grafted place with black film.

When grafting, the bark should be in contact with each other.
