Rationing the number of brushes on grapes

Rationing the number of brushes on grapes

The rationing of grapes on grapes enables the quantitative and qualitative properties of future harvesting.

Rationing the number of brushes on grapes

The purpose of rationing

The main purpose of the ration is to take the vine the strain that it cannot endure. When the berries are overloaded, the plant is formed much more than it is able to provide good nutrients for growth and development.

Table varieties with large fruits tend to form excessive fruit formation.

As a result, the harvest does not reach the size of the berries and their taste qualities that are intended for the variety of varieties. The deflection on the maturation of excess food fruits leads to the exhaustion of the plant and to poor maturation of the vine and does not make it possible to prepare the horticultural culture for wintering in a suitable manner.

Time of normalization

The normalization of the number of berries in the vine takes place before the flower phase begins, whereby the size and number of inflorescences are visually assessed on individual drives. The best option for an adult fruit strut is early normalization in the presence of completely or partially formed inflorescences. In this case, the entire food begins to flow into the abandoned grapes, which has a positive effect on the size properties and prevents the nutrient flow to the berries that still need to be removed.

When determining the normalization period, they are based on the rule: varieties with stable pollination are normalized in the stage of the formation of inflorescence, in young bushes with poor pollination quality in earlier seasons, the load on the grape shrub is regulated at the end of the flower.

For inexperienced breeders, it is possible to determine additional inflorescences in visual inspection immediately after the end of the flowering and pollination phase if well-shaped ovaries are visible.

Calculation of the number of clusters

The following features are taken into account when calculating the load of a grape shrub:

  • Concept of technical maturity,
  • Average weight of the grapes,
  • The size of the resulting berries,
  • Winter hardness,
  • The length of the autumn cut of the vine.

Together, these parameters help to determine the optimal normalization for a grape shrub.

Mathematical approach

Some winegrowers use the Magarach formula: m c * n, where M is the optimal number of eyes of a grape shrub, n The number of powerful shoots is C is a correction factor that is assumed at 2.5.

Such a formula applies if the standard for a bush is not calculated according to the future yield, but according to the number of eyes. In this case, the correction factor takes into account losses. One of the minus points is the need to adapt the normalization indicators after pruning the shoots.

Corporation pure approach

The hand norm depends on the variety

The brushstorm depends on the variety

Most breeders determine the standard for a grape bush according to variety features:

  • For larg e-fruity table species with earlier ripeness with a bundle weight of 0.8 kg and large berries of 3.5 * 2.5 cm – with a rate of 1 per 1, such varieties are much longer with great yield, with great yield, for a large amount,
  • For types of blackboard with a bundle weight of up to 0.5 kg – with a rate of no more than 2 per 1 drive,
  • For technical species and types of table with a fret weight of up to 0.2 kg – 3 or more per 1 drive.

Varieties with bushes from 1.5 kg remain sterile with every third. Small brushes of rosin varieties do not require normalization.

The older the vine, the greater the harvest that she tolerates, but the number of brushes on the shoots is gradually increased, usually plus half an additional brush for every following year.

Some varieties can form brushes with an increased berry density, which means that the fruits contained therein do not ripen. Such clusters are normalized by thinning, with up to 30 % of the fruits.

Features of normalization

When calculating the normalization of the future grape harvest, some factors should be taken into account, the presence of which requires a reduction in the weight to be due to grape drive.

The earth

When growing large fruity varieties, the saturation of the soil with phosphorus and potassium is taken into account when calculating grapes in grapes, which can provide good nutrition for the number of brushes selected during the rationing. If the bioactivity of the soil is in the stage of education, it is recommended not to leave more than 1 brush per 1 drive on large fruity varieties.

Fros t-resistant varieties

For the subsequent successful wintering of the plant, the frost resistance boundary of the variety variety i s-21 ° C. In the absence of such a feature, the burden on the vineyard in relation to the empirically calculated indicators is reduced to ensure the number of elements required for the winter, and the brushes are less than arbitrarily expected.

Grapes: how many brushes leave?

7 Consequences of overloading a grape shrub with a harvest

The overload of the bush has serious negative consequences:

  1. The ripening is significantly delayed;
  2. Grapes lose their appearance, berries become small and / or heterogeneous in size;
  3. The sugar content decreases;
  4. The next year promises to be vulnerable, the harvest of the next year will not be put on the right level;
  5. Drives grow badly and tires bad;
  6. The overall hardness of the bush decreases;
  7. The yield and resilience of the plants against diseases decrease.

When do you start rationing the harvest?

After pollination and berry approach (2-3 mm), the yield of the current season can be estimated. However, one thing has to be taken into account: removing the inflorescences before flowering does not reduce the harvest quantities and does not weaken the bush.

To remove unnecessary grapes at a later date when the berries have become larger than 3-5 mm leads to harvest losses, loss of bush resistance for free.

How is the rationing and how many brushes should remain?

  • Remove the grapes on the drives of replacement nodes completely,
  • Fully remove the grapes on underdeveloped shoots,
  • Fully remove the grapes on damaged drives.
  • Grapes are completely removed if there are not enough leaves on the drive above the thunderstorm.
  • If the bush gives the very first clusters, 1-2 control clusters are left for testing on such a bush – the rest is removed.
  • On a young bush 2-3 years of life – they strictly leave one (no longer) cyst per drive.
  • On an adult, medium-sized or strong bush with tufts and berries of small and medium size (150-250 g), 2 tufts remain.
  • On an adult bush-when the variety is stronger, and the clusters have an average size of 300-600 grams, 1-2 (often two) clusters that escape are left at a time.
  • In an adult, strong a bush with large and very large clusters (700-1200 g and more), only one cluster remains to escape.
  • You need to leave more complete and even brushes, regardless of the top brush or bottom.
  • The remaining brushes should lie optimally to one another.
  • Famous strains don’t ration the harvest.

These are the main points for standardizing the load on the grape bush.
