When should persimmon trees be grafted?

When should persimmon trees be grafted? After cutting leaves in summer, cut off the new branches of the year and graft. Because there are many tannins and high survival rate, cashew trees are really suitable for grafting. Branching grafting or budding can be used. Generally speaking, Dos Ramos grafting is carried out from the end of March to the beginning of April. Split grafting, subcutaneous grafting and abdominal grafting can be used before and after germination of rootstocks in spring. When the rootstock seedlings are low, several grafting methods are suitable for dopa grafting. The time and method of Cada transplantation are different.

For example, the grafting method is usually carried out from March to April. There are usually two kinds of TEM suitable for bud grafting, one is summer and autumn, the autumn starts in August, and the other is spring and summer. There are three grafting methods for cashmere trees: nest grafting, nest grafting and grafting. Generally, plants are divided in the spring around March. At this time, the sap flow of rootstock is dormant, and the survival rate of division is high. Bud observation: cashew trees can be grafted in spring. Generally speaking, it should be carried out when healthy roots have begun to sprout and appear green, but the buds of spark plants have not germinated or are about to germinate.

At the same time, it is best to graft Zhou Shu in spring, when the root system has sprouted, showing green shoots, and rye has not sprouted or will soon germinate. Now, the surface of persimmon grafting can produce callus; The optimum grafting temperature is 20℃; The best time is from the end of March to the end of April, and the best time is mid-April, when the rootstock buds germinate and expand, but the leaves do not expand. The survival rate of transplantation is the highest, reaching 98.7%, while the survival rate of early and late transplantation is obviously reduced, which can be carried out in summer. It is more suitable before and after the complete solar term.

In the north, this may be because the khaki branches contain a substance called tannin, which directly affects the success of grafting. The reason why we choose to graft when the branches are about to sprout is also because the tannin content of Caqui branches is grafted in advance at this stage. It will take several years, and grafting planting will greatly shorten the fruiting cycle. So most of the booths we bought in the market were grafted. So, today, I'm going to explain to you the best grafting time of cashew trees. When choosing the grafting time and method, it needs to be more than two years, healthy and moth-free, and the trunk length is 10 cm.
