Can the various grafting methods on the Internet really survive?

As long as the method is correct, where watering is carried out in the grafting period, the survival rate is low, and the soil moisture content is generally kept at about 16% in the grafting period. Therefore, it must not be watered during the grafting period. When grafting, it is best to choose when the weather is fine, and do not do it in rainy weather, so as not to affect the survival rate after grafting.

As long as the grafting methods on the Internet can really survive, the reason why there are a variety of grafting methods on the Internet is actually because different plants need to adopt different grafting methods.

A lot of it is okay. Choose the right season, the right soil, and follow the method step by step, and the chance of survival is still very large.

The method of checking the survival of fruit trees after grafting is as follows:

1.The survival test of bud grafting is carried out 10 to 15 days after grafting, and the sign of successful survival is that the bud is fresh and the petiole falls off at the touch. If the buds shrank and are dark, the ones that don't fall off the touch don't survive.

For those who do not survive, they should be replenished in time.

2.The survival test of the graft is checked about 1 month after grafting, and if the scion is fresh, the wound heals well, and the bud has germinated and grown, it indicates that it has survived.

When grafting, pay attention to the essentials of operation, first cut the wood, cut the scion short, shorten the water evaporation time, the tool should be sharp, the incision should be smooth, the shape should be aligned, the parenchyma cells should be tightened, the joint should be tight, the binding should be tight and appropriate, and the grafting should be checked in time.

The grafting method with the highest survival rate: plugging method, relying on grafting method, and splitting method.

1. Plugging method

First, use a bamboo skewer to remove the growth point of the rootstock, puncture the jack from the midrib at the base of one cotyledon to the hypocotyl of the cotyledon on the other side, and place the rootstock on the operating table. Then pick up the scion seedlings and cut the scion, then pull out the bamboo skewers on the rootstock, and immediately insert the scion, as deep as possible to promote healing and improve the survival rate.

2. Relying on the connection method

Also known as tongue jointing, it involves a bevel cut on the rootstock and the scion, with the edges facing opposite directions and similar in size, and then the incisions are fitted. The whole process must be fast, the rootstock and scion are cut and immediately matched, and firmly clamped with grafting clips, and then the grafted seedlings are planted in the nutrient bowl.

3. Splitting method

First, the stem above the rootstock is split from it, then the upper part of the scion is cut into a wedge shape and inserted into the incision of the rootstock split. Adopt this grafting method, the rootstock seedlings used are older, sow rootstock seedlings first, and then sow germination scion when they can be transplanted, and can be planted in the same nutrient bowl.

Wedge requirements for grafted rootstocks and scions:

There are mainly triple cutting methods, namely single-sided wedge, double-sided wedge and tongue-shaped wedge, and single-sided wedge is suitable for miter cutting and bud jointing. The double-sided wedge is more suitable for splitting and top plugging method, where the young stem is cut into a double wedge from top to bottom, and the tongue-shaped wedge is mainly used for the grafting method, which needs to be cut into the stem obliquely with a blade from a certain position on the stem of the seedling.

3. The reason for the survival of all grafting lies in the close combination of the cambium layers of scion and rootstock and the role of living together. When two tree species with affinity are grafted, the rootstock and scion are in the condition of sufficient nutrition and vigorous life function, the wound callus quickly fills the gap between the ear and the anvil, and the adjacent parenchyma cells have intercellular connection, and the protoplasm communicates with each other, and the inter-anvil conduction tissues are connected with each other to form a common cambium layer, so that the scion can get the nutrients and water of the rootstock root system, and gradually grow into a new plant. Therefore, the key to the survival of grafting is mainly determined by the regeneration ability of anvil, interpanicle cambium and parenchyma cells and the degree of callus production.

Why does grafting survive? How do scion and rootstock grow together?

The following explanations: 1. The grafting interface is a V-shaped callus, the lower part of the V-shaped is an acute angle, the callus at the interface is obvious, the upper part of the interface is thicker than the lower part, the skin color of the skin and the rootstock above the grafting interface is obviously different, the opening angle of the new branch is large, and there are many branches, and this kind of seedling is grafted into a live seedling;

2. The petiole fell off after 7 days of bud grafting, and the bud did not dry, and the necrosis was grafted into life;

3. The most accurate criterion for judging that the pure tease seedlings of the grafted tree have survived is to continue to grow after 15 days of germination.
