What caused the death of newly grafted cherries?

It's an honor to be here to answer your questions. There are many reasons for the death of newly grafted cherries. Let me introduce you.

Causes of grafting death

1. grafting season and time? First of all, at the end of March in spring, the time is about half a month, and the disc spindle budding splitting method can be used. Secondly, grafting can be carried out in the middle and late month by plate budding or η-shaped budding. Finally, grafting in autumn, from the end of August to September, can use the strip bud grafting method. If the season and time of grafting are wrong, the grafted cherry tree will die.

Second, the best rootstock tree species? The object with cuttings is called rootstock, and the tree species of rootstock have strong affinity with cuttings, which is the premise and foundation of grafting survival. The ability to produce healing tissue between rootstock and scion is weak, water and nutrition cannot be transported, and grafting fails, resulting in cherry death.

Third, grafting humidity and temperature?

When the temperature is too high over 28℃ or too low below 15℃. Callus can not be formed, and grafting activity is low. If the soil humidity is too high, glue will flow on the interface, which will affect the survival. If the water is watered during the grafting period, the survival rate is low, and it is more appropriate to keep the soil water content around 16% during the grafting period. Don't water during grafting. In order to prevent soil drought, it can be watered once a week before grafting and not watered for half a month after grafting. If cherry is exposed to hot and high temperature, it is difficult for grafted seedlings to survive in direct strong light. Therefore, when grafting, the parts must avoid direct sunlight, and it is better to graft where there is light behind.

Cherry tree grafting

1, root connection? There are three kinds of root grafting: ① Cut off the rootstock with the main root neck, cut the joint between the cortex and the wood fruit about 4㎝ at the edge of the cut, insert the scion about 10cm, and wrap it with plastic film. (2) For larger woodcuts, the big lateral roots can be dug out from the tip, cut from a proper thick place, then cut into scions, grafted and buried with soil. (3) Root bags with roots can be grafted at the cost of each root.

2. grafting? Give two examples: ① Make a spoon-shaped V-shaped incision on the bark of the stump, loosen the cortex on both sides, and graft the scion in, so that the skin and bone are opposite and wrapped. ② Small rootstocks can be cut from the ground 10 cm, and then scions with a length of about 10 cm can be grafted from the cortex at the edge of the wood incision.

Step 3 bud grafting

Take three kinds of T-buds as examples. First, choose a smooth place on the resistant wood. First a horizontal knife, a vertical knife. The two knives are T-shaped, about 3 cm long and reach the xylem. Then, cut the buds from the scion, connect them and wrap them. ② Flake bud grafting: cut the cortex at a smooth place at a distance of 10 cm from the ground, stick the bud piece on it and wrap it. After survival, cut off the upper end of the glued wood interface. ③ The cut on the wood marked by inverted T-shaped buds is inverted T-shaped, and the connection method is the same as that of T-shaped connection.
