SYLVOZ SYSTEM FOR THE SCREW
It is a training system with rich pruning, suitable for fertile and fresh soils for vigorous vines, very widespread by virtue of the qualitative and quantitative results it guarantees. Originally from Savoy, it is characterized by a long pruning system. It includes a 1.5 to 2 m high shaft that folds into a 2 to 3 m long permanent horizontal bead placed on the second wire of the scaffold. On the cord there are the fruit heads bearing 8-12 buds, distributed along the cord every 40-70 cm; these are folded to the headband and attached to the lower end. The shoots, which arise from the curves or from the special spurs, are used for the renewal shoots; they are grown vertically fixed to the third wire placed at about 2 m in height. A spur can be raised at the base of the fruit head for vegetative renewal.
In the Sylvoz system the distances on the final are two-3 m and three-4 m between the rows. The framework formed by steel poles 2 to 2.5 m high above the ground and 6 m apart on the row. The galvanized poles hold 5 or 6 wires, of which the lowest, 1 m from the ground, is used to fix the arches, the second holds the horizontal cord, the rest, which are spaced 40-60 cm apart, are used to fix the new one. vegetation.
Using the Sylvoz system in the breeding phase, the normal short pruning is practiced for the first two years, in order to strengthen the plant, leaving only one slice to reach the second wire. In the third year, the last two shoots are grown in the upper part of the stem.And in the fourth year, chosen the best, it bends over the second wire, forming a permanent cord that will be gradually stretched until it reaches the vine is close, without however ever go beyond it. In production pruning, the arch that fortified is eliminated, replacing it with a blunt line on the curvature. Like the previous one, there are also numerous variants of this breeding system, including the bilateral Sylvoz and the Casarsa.
