In practice, the steppe regions of Ukraine
the most prevalent forms of fan cupped bushes. Cupped no shtamb
form used in areas where the vineyard is established Dwarf support or
none at all. If you or be tied to a stake sheaf shoots and brush
adjacent to each other. As a result, deteriorating bushes (poor lighting
and poor ventilation), reduced crop quality. Enabling load on the bush
eyes at this forming allowed very limited, which makes it impossible
to obtain high yields.
Pict. 1. Derivation of forming a bush fan:
1 - a seedling in the year of planting, 2 - at the end of the first or second year and 3 - in the spring of the second or third year, 4 - in the spring of the third or fourth year, 5 - in the spring of the fourth or fifth year
When the sleeves will develop
eyes, leaving the top 4.3 flight of the strongest. If the bushes are no
strong shoots, and long sleeves to create, existing vines are pruned in
the right place at 2-3 buds on a twig. The following spring from them
form long sleeves. To create short sleeves vines pruned to 2-3 buds.
Results on the bush should be 4.6 sleeves of varying lengths.
Pict. 2. Withdrawal cupped shape bush
Formation of the bush usually extends over 3-4 years. But this process can be accelerated. To do this, to grow strong bushes in the first years after planting, which is achieved by the use of irrigation, fertilizers and thorough care of the soil. On young bushes strong vines, when they reached 6.7 internodes, pinch out over a 4-5th leaf. As a result, developing stepchildren, of which the following spring form long and short sleeves, all the strong shoots on the sleeves again pinch, forming fruiting units (arrows and swirls on the vine replacement).
