Successful grafting of jujube trees is conducive to growth, how to graft jujube trees?

The grafting of jujube trees can generally be selected from four methods: skin grafting, splitting, ventral grafting, and bud grafting. Plugging joint, also called subcutaneous joint. This method is suitable for grafting jujube trees where the rootstock thickness is greater than the scion thickness and the rootstock germinates and debarks.

First of all, we should learn professional grafting technology, and we should also water and fertilize in time, and we also need to timely top dressing, and we also need to choose phosphate fertilizer and nitrogen fertilizer, and we should also ensure that the light is sufficient, and we should also maintain the permeability of the soil and do a good job of loosening the soil.

It is necessary to choose the branches to be thicker for grafting, so that the survival rate will be higher, and the appropriate time for grafting should also be selected, and fertilizer should be supplemented in time.

Successful grafting of jujube trees is conducive to growth, how to graft jujube trees? 1. Grafting timeGrafting jujube trees is suitable for carrying out between April and September every year, when the plant is in the growth period, and the trunk and branches grow relatively strong, grafting will not affect the growth of jujube trees in the later stage, pay attention not to graft in rainy days, otherwise it will affect the recovery of plant wounds. 2. Handle branchesBefore grafting jujube trees, it is necessary to select the lignified branches that are free of diseases and pests from the mother plant, and then cut the bottom obliquely into a 45-degree oblique angle, and cut off the leaves of the branches from the bottom to the top 10 cm, leaving only the top 3-4 leaves.

3. Handle the rootstockBefore grafting jujube trees, it is necessary to select rootstocks that are free of pests and diseases and have no damage, and then spray carbendazim on its surface for disinfection and sterilization, and then use the sterilized knife to obliquely cut out a V-shaped incision at the position of 1 4 on the surface of the rootstock. 4. GraftingAfter processing the branches and rootstocks of the jujube tree, you can insert the bottom of the branches into the incision of the rootstock, and then use a plastic rope to tie the branches of the jujube tree to the rootstock, and then use a plastic bag to cover the two together to prevent the wound of the plant from being infected by bacteria.

<>1. If it is generally carried out in summer, it can grow about one to two meters in that year, which is better than that in spring. The time of grafting is generally selected from June to September, and the time should not be too early. If it is too early, the jujube is not fully ripe and cannot be used as a scion, and if it is too late, the temperature will be low, which will affect the survival rate.

The jujube trees in the village can be grafted from March to August, but grafting from mid-April to early May not only has the highest survival rate, but also grows new branches in that year.

At the beginning of the month, select the adult jujube trees that are strong and disease-free, collect the jujube heads of the current year, and pay attention to judging whether the jujube heads have been completely lignified. After harvesting the scion, cut off the leaves immediately, leaving only the petioles, and then wrap them in a clean, wet towel with plastic wrap on the outside and tie the mouth of the plastic bag to reduce water evaporation. Before cutting off, you can peel a circle of bark at an appropriate height, and after a while to see if there are new branches under the ring peeling opening, if so, you can keep it and slowly cultivate it into a new jujube head, and then cut off the original crown.

If there are no new branches under the ring peel opening, wait for the ring peel to heal and then switch down to the empty position of the bridge and peel again until a new branch bud appears. When grafting, don't graft all the branches on a tree, just graft some branches. For grafting, high grafting is preferred, and thick and erect is the best.

In addition to cutting, splitting, and ventral jointing, it can also be plugged into the skin, bud jointed and other methods. The grafting time can be continued until mid to late May. In July and August, the seedlings that have not been vied can be regrafted.

Be sure to keep an eye on the time and don't miss it. When grafting, the action should be rapid, and the rootstock and scion should be cut in strict accordance with the technology, and the joint surface should be smooth, so that the cambium layer of the rootstock and the scion should be closely connected, the binding elasticity should be moderate, and the binding should be untied in a timely manner.
