Pruning of vine
In the vineyards of Ukraine for the winter shelter thoroughly ground. In this regard, the rod is removed from the poles and make a preliminary pruning shrubs. It involves removing a significant amount of end fructuous vines, that is, reducing the amount of the bush, but not all chasing the shoots. When pre-trimmed leaves a considerable amount of spare vines (3-4 in the bush).
In the spring, before trimming, establish the extent and nature of renal damage in the eye, the state of the wood of annual and perennial parts of the bush and roots. Only with this in mind, the decision on the extent and nature of the crop. On pruning vineyards set load bush crops. It is closely associated with the preservation of fruit buds and wood bush.
With the end of the formation of clusters annual pruning should be to remove end fructuous shoots on old hands and the formation of new points and knots in the last year. With this new knot is left below the arrow.
Shoots arrows at last year's completely removed only if parked on a branch develops at least two shoots and eyes are well preserved, it is possible to establish the normal load of fruit from a bush points and knots. If the knot in last year's shoots are missing or poorly preserved fruit buds, on the part of the sleeve end fructuous choose flight or two and they are cut as extra hands.
Load on the bush in the little eyes set depending on the biological characteristics of the variety and method of formation.
When the fan in the stands forming technical grades of the average load on the bush should be 60 - 65 healthy eyes, in plantations of table varieties - 40-50. With irrigation, the load on the bush increases almost 2-fold.
In the vineyards with the cup-shaped form, with the support code, the load should not exceed 20 - 25 buds on a bush. Typically, a load of little eyes when cutting some increase, and refine it during the first pieces of the shoots. This makes it possible to more accurately adjust the value of the crop.
The sleeves are usually 5-6 years. As soon as the growth of shoots at the ends of branches is reduced and the bushes produce large quantities of fat shoots produce rejuvenation sleeves. With the weakening of the growth of bush rejuvenate its entirety. New sleeves derive from strong shoots of fat, which is selected in the right place. In their first year on a limb cut off, and the next - strong stems are cut at the sleeves below the - on the twigs. On the sleeve after bud burst leaving only the top 3.4 eye, the bottom is removed.
In the spring of third year in a new sleeve shape fruit element, and the old is removed, leaving the stump to 1.5-2 cm
As we age due to injuries inflicted by year, the bushes grow old and weaken. Then they completely rejuvenate the truncation of all above-ground parts. Of the strongest shoots create a new form of the shrub.
