Fruit trees can not be planted without grafting. How to improve the survival rate of marriage?

Abstract: there are many benefits of fruit tree grafting, how to improve the survival rate of grafted fruit trees?

Grafting belongs to asexual reproduction, the principle is to select a good affinity scion and rootstock, make them closely combine, in order to ensure the survival of the scion. The method of grafting has many advantages. It can not only maintain the excellent characters of scion varieties, but also make use of the favorable characteristics of rootstocks to achieve early seedling formation, early flowering and enhance the ability of drought resistance and pest resistance. The grafting of some plants and flowers can significantly improve the economic value and ornamental value.

Although grafting has so many benefits, but not any two species can be grafted together, is suitable for grafting together, there is no good grafting technology, it may not survive.

So what problems should be paid attention to when grafting in order to improve survival?

The first is to choose the right two materials. For example, cucumbers can be grafted onto black-seeded pumpkins, peaches, plums, apples and kiwifruit can be grafted with each other, different kinds of tomatoes can be grafted, and flowers can be grafted basically. the basis of selection is that the two had better be varieties of the same family and genus, and the thickness is basically the same, which can improve the survival rate.

The second is that grafting should pay attention to the grasp of time, and different crops should choose the appropriate grafting time. Fruit trees are generally grafted in early spring, summer and autumn. Grafting is carried out before the sprouting of fruit trees in early spring, after the maturity of scion buds in summer, and at the end of summer and the beginning of autumn. Fruit tree varieties can be grafted in early spring, with the exception of grapes, which need to be grafted in summer. Persimmon trees planted at home are usually grafted from mid-March to early April. The overall selection principle is that the rootstock and scion are in the budding or growing period together.

The third is to choose the appropriate grafting method. Cucumber generally chooses connection method and insertion method, which is easy to operate and has a high survival rate. There are two kinds of insertion methods: oblique insertion and direct insertion. The grafting method does not take root when grafting, so it is easy to appear the phenomenon of withering, which requires higher grafting techniques. It is easy to survive by grafting, but the wound needs to be taken care of to avoid infections such as bacteria.

Finally, there are some details and management that need to be paid attention to. Tools such as blades and scissors for grafting, as well as rootstocks and sprouts to be grafted must be disinfected first. The sterilized rootstocks and sprouts can be soaked with naphthylacetic acid 200-3000PPM to improve the survival rate. After the grafted panicle buds and rootstocks are integrated, they should be unbound in time. If the grafted branches are too prosperous, they should also be peeled off to ensure balanced growth.
