The mobile grape trellises

The amount of the work in the vineyard, its yield greatly depends on what type of grape trellis is used in the vineyard.The most common is the Vertical Shoot Position. The advantages of the Vertical Shoot Position is the simplicity of the device and the use of inexpensive building materials. It is less time consuming and easily accessible for vineyard care.The disadvantages are that the maximum area of the green mass and the maximum yield cannot be obtained. The horizontal grape trellis system - pergola - allows to get the maximum area of green mass, the maximum assimilation of solar energy takes place, that increase yields by 2-3 times and provide the best quality of grapes.The disadvantages is that the care of vines grown on horizontal trellis is very time-consuming. Because the vintner is forced to work with his head constantly pulled back and his arms raised high.The authors have developed a new type of grape trellis - a mobile pergola - which during the vegetation - during the development of green mass and fruit ripening are placed horizontally, and during the green operations - pruning, spraying, harvesting - in a vertical position. As a result, we get a high yield typical for the pergola, which is 2-3 times higher than the yield obtained on the vertical grape trellis, and its maintenance is just as convenient and simplified as that of the vertical grape trellis.
