Growing grapes on your own gardensite - an exciting and useful activity, but requiring a lot of effort and attention. In addition, from time to time it is necessary to perform a procedure such as grafting, which is used to restore a bush or replace one variety with another. In this article we will look at how grapes are grafted in autumn and winter.
What is an Inoculation?
Vaccination is a way to grow grapes, withwhich part of one plant is transferred to the shoot or the trunk of the other. The part that is planted is called a graft. The plant on which the vaccine is produced is a stock.
An old variety with its qualities always remainsfrom below, and from above - a new variety that retains its own characteristics. As a result, a single organism with features inherent in different varieties is obtained. Often, several varieties of grapes are planted in one bush, which have different maturity and color of berries. The resulting bush is called a bouquet.
Why are grapes planted?
This question is of interest to many novice wine growers. We can note some advantages of grafting grapes:
- The grafted plants are much fruited earlier. Thanks to this procedure, the first bunch of a new grape variety appears already the next year after planting.
- Inoculated bushes increased yield. Sometimes such grapes give larger clusters and fruits.
- Inoculation allows to accelerate the ripening time of some varieties of grapes.
- Another plus of such an operation: this is a great way for the rapid reproduction of difficult in cultivation, rare and scarce varieties.
In the south, grapes are planted toThe root system was resistant to the phylloxera. This aphid, which lives on the roots of grapes and feeds on its juice, while it can damage not only the root system, but also leaves. Because of this, the bush withers and dies. Grafting in the southern regions is also used to increase the fruitfulness and drought resistance of the plant.
In the middle zone, where the soil is poorly drained, such a procedure is necessary to combat high humidity and acidity.
In the north, grapes are inoculated to increase the periods of its active growth and development.
Preparing cuttings for grafting
In order to graft grapes in autumn orIn winter it was successful, it is necessary to take care of the preparation of the cuttings. For their cutting, only the ripened vine is used, which has a yellow-brown color. The bark must be firm and dry. The most suitable for harvesting cuttings are shoots that have grown on a fruit vine.
The diameter and length of the cuttings are very important.The standard is a length of about 55 cm, diameter - 6-12 mm. Shanks must be cleaned of the antennae and stepsons, while trying not to damage the kidneys. Then two cuts are made - the first one is 0.5 cm below the knot, the second one is 2-3 cm higher. The vine, sprinkled with sand, is stored in a pit that has a depth of about 60 cm. With the arrival of frosts, it must be insulated.
What is needed for grapes in autumn
Grafting in the fall begins with trainingtool. It is necessary to take care that the pruner and knife are sharpened sharp. To keep the tools dull, it is best to store them in covers. Before vaccination, they must be disinfected with alcohol and not put on the ground during work.
Grape vine is removed from the store in a weekbefore the procedure. Cuttings for autumn grafting in advance do not cut into pieces, it is done immediately before the operation itself. To the place of the procedure they are brought wrapped wet sacking.
How does the vaccine work?
Autumn vaccination of grapes occurs in such a wayway. First, around the old root dig a hole. Then it is necessary to cut down all of its aboveground part, the cut is made at a distance of 10 cm from the ground. The cut location must be level, unaffected by pests and diseases. The stub is cleaned from the old bark and treated with a 3% solution of copper sulfate.
Grafting in winter
Winter, or table, vaccination of grapes is made in the period from February to April. Such an operation can be carried out directly at the desk, hence the name.
Для прививки необходимо подобрать подвой и привой one diameter and make slanting slices on them. With the help of tongues, cut on them, the graft is connected to the stock. In the place of inoculation, the plant must be wrapped with a film, then place the seedling in wet sawdust. Capacity put in a warm place. If the winter grafting was done correctly, then after 15-20 days a seedling can be transplanted.
If for some reason you do not like the varietygrapes, growing on your site, or the plant is damaged, do not rush to uproot it. Carried out according to the technology of winter or autumn grafting will allow you to replace one of its varieties with another, restore the damaged plant, and also quickly multiply valuable, but rare species.
