How to improve the grafting Survival rate of Persimmon

Grafting is a very commonly used planting technique at present, and the most commonly used method for persimmon trees is grafting, but in the process of using grafting technology, the survival rate is not satisfactory. There are many factors affecting the survival rate of grafting, such as incorrect selection of rootstocks, poor quality of rootstocks and scions, grafting time, weather, improper grafting techniques and methods, and so on. So how can we improve the survival rate of persimmon grafting? Let's take a look at it with the editor.

1. Selection of rootstock and scion

Improper selection of rootstocks is the most basic reason for the failure of persimmon grafting. We should choose one-year-old or three-year-old persimmon branches with a diameter of about two to three centimeters, which can be used as rootstocks for grafting. As for the scion, we should first choose the seedlings suitable for grafting persimmon trees, such as fine seedlings with smooth skin and no diseases and insect pests. Only when the rootstock and scion are properly selected can the follow-up work be carried out smoothly.

2. Grafting time and climate

Grafting we generally choose in cloudy days, no wind, humidity of the weather grafting. Although it is said that the humidity is relatively high, it can not be grafted on rainy days, and grafting can not be carried out before and after rain, because it will affect the healing ability of seedlings and lead to grafting failure. Grafting can not be carried out in sunny days, the survival rate of grafting in sunny days is very low, because persimmon trees produce high tannins during this period, which will hinder the healing of rootstocks and scions.

3. Grafting techniques and methods

At present, there are three kinds of persimmon grafting techniques, namely, split grafting, bud grafting and grafting. The splitting method is suitable for spring, that is, around March, when the sap of the rootstock flows, the sprouts sprout and the scion is dormant, and only the survival rate of split grafting will be higher. And bud grafting is carried out in summer, generally during the period from the Beginning of Summer to Grain in Beard, especially Lesser Fullness of Grain, the survival rate of grafting is the highest. Grafting in autumn is usually done by means of nested grafting, mainly during the period from August to September.

4. Management methods after grafting.

After the persimmon trees are grafted, we should always check the grafting. Wipe off the sprouting branches from the rootstock in time so as not to affect the healing of the rootstock and scion. The second is to untie or loosen the condom in time after survival. If the persimmon trees are grafted in summer, we also need to cut off the rootstocks on the buds in time. The last is to do a good job in field management, timely watering, weeding, loosening soil and topdressing and so on.

It is believed that many people have tried the grafting methods of persimmon trees and even other seedlings, and their survival rates are high and low, which mainly lies in the grafting technology. This is a simple way to improve the survival rate of persimmon grafting, which is sorted out by the editor. I hope it can help all the friends who love grafting.
