Factors affecting the Survival of Apple grafting

Apple is one of the bulk fruits, it is rich in nutrients, and its calories are very low, very suitable for weight loss, at the same time, its nutrients are easy to be absorbed and used by the human body. Many apple seedlings are cultivated by grafting, but there will be a lot of errors in the process of grafting, resulting in the failure of grafting. So what the editor wants to introduce to you today is the reasons that affect the survival rate of apple tree grafting. Let's take a look.

1. Rootstock combination

The grafting survival rate of apple trees is closely related to the combination of rootstocks and scions. The stronger the healing ability between rootstocks and scions, the higher the survival rate of grafting. Then the affinity between rootstocks and scions has a great influence on the survival of apple tree grafting, and M26 is often used in the rootstock which is more suitable for apple tree grafting. The healing ability of this kind of rootstock is the best at present, which is much better than that of Asustek, honey crisp and other varieties.

2. Scion selection

The quality of scion also has a great influence on the survival of apple tree grafting. We should choose scions that are suitable for local growth, high quality varieties and high fruiting rate. Secondly, the scion should choose Xiangyang area, robust, pest-free, well-developed, full shoots, no damage to the branches. Harvested scions to maintain freshness and a certain degree of humidity, it is best to store in the temperature of zero to five degrees or so, the humidity is maintained at about 90%. The temperature and humidity should not be too low or too high, otherwise it will affect the healing tissue of the scion and the survival rate of apple tree grafting.

3. Grafting management

Grafting management is the key to affect the survival of apple trees, and the quality of grafting technology directly affects the survival rate of grafting. First of all, we need to deal with the scion, generally truncating the scion about six to ten centimeters, must have two or more buds, and then cut the truncated scion into a smooth slope with a knife. As for the rootstock, we also truncate it into six to ten centimeters, deal with it smoothly, and finally choose a reasonable scion according to the size of the rootstock. When grafting, we need to align the interface between the rootstock and the scion, and then wrap it with a plastic sheet. when binding the plastic film, we should pay attention to it tightly, tightly and firmly, which can improve the survival rate.

4. Management in the later stage of grafting.

The management after grafting of apple trees has a great influence on the survival rate of grafting. If the management work in the later stage of grafting is not in place, it is very likely that the original surviving apple tree will die again. Generally speaking, about ten days after grafting, it is necessary to inspect the grafted seedlings in time, and if it is found that the grafting did not survive, then make up the grafting in time. When the new branch after grafting grows to about 18 centimeters, be sure to uncover the bound plastic film and tie the bracket when it is opened.

The main reasons affecting the survival rate of apple tree grafting are the selection and treatment of rootstock and scion, grafting treatment, grafting method and seedling management in the later stage.
