METHOD OF FORMING, PRUNING AND MAINTENANCE OF GRAPE VINE Russian patent published in 2009 - IPC A01G17/00 

FIELD: agriculture.

SUBSTANCE: method consists in row planting, raising of slanting cordon with grape links, and in vertical raising of green growth on trellis in several tiers. At the end of the second year of vegetation extra sprouts on the head of the vine bush at soil surface are cut off except two strongest. The strong sprouts are pruned before beginning of the third vegetation at length exceeding the space between vine bushes in a row and are pleated into an integrated twisted stem in form of a plate. The plate is fastened with its upper end to the lower tier of the trellis at the angle of not less, than 45°. At the upper part of the twisted stem two or three sprouts are left with incline into direction of the slanting stem. To form a twisted shoulder of the cordon in form of a plate out of two-three well developed sprouts this shoulder is secured in horizontal position to the lower tier of the trellis thus creating a continuous trellis in a row. One or two eye twigs are left in each knot on twisted shoulders of the cordon during manual or mechanised pruning. Sprouts produced by twigs in spring are broken off with leaving 15-20 sprouts for an industrial variety and 12-15 sprouts for a table variety per running meter of the trellis. Growths of sprouts are arranged vertically between parallel wires of the second and the third tier of the trellis. After pruning for covering vine bush for winter the lower tier is taken off hooks of intermediate trellis posts. Further vine bushes together with wire are placed on ground surface in a section line of the row and earthed up with a bank covering slanted stems, cordons and twigs. In spring vines are uncovered. After uncovering the lower tier of the wire together with vine bushes are lifted from the ground surface and are hanged on hooks at the height of 45-50 cm to the intermediate trellis posts with following stretching of wire with a winch.

EFFECT: reduced labour intensiveness at cultivating vineyards in zones of covered vine-growing; increased efficiency and profitability.
