Abstract

The invention relates to viticulture. The purpose of the invention is to preserve the productivity of plantings and extend the operation of the vineyard. The method includes the operations of stubbing up old bushes, rejuvenating the remaining ones, growing young shoots from them with the subsequent formation of crown in these shoots. To form a crown, shoots are grafted with a graft variety, and then the graft is rooted in an apical end in pairs from two adjacent bushes in the holes located between the rows. After bruising, the shoots are separated from the rejuvenated bushes, and the bushes are removed.

Description

The invention relates to viticulture.

The purpose of the invention is to preserve the productivity of plantings and extend the operation of the vineyard.

Example. The tests were carried out on the variety Rkatseteli, with the arrangement of bushes 2.5 x 1.5 m, on an area of 0.6 hectares, the age of plantations is 16 years. A known method was tested as a control.

In the first year of testing at an experimental site in early spring, before bud break, a rejuvenating pruning of the bushes was carried out in a row, one after the other. The old parts of the bushes were removed, 2-3 young vines were left, growing from the head of the bushes. In May, after the shoots reached a length of 40–50 cm, pro-1- normalized debris was carried out, separately by two most developed shoots. At the beginning of July, on each of these shoots, they were inoculated with a graft of Ripara x Rupestris Cober 5 BB, at a height of about 1 m from the base of the shoot. In the fall, the bushes were cut accordingly, and the grafted shoots were above the budding site.

In the second year, during the growing season, fragments of shoots were conducted on grafted vines below the budding site, except for the two upper ones. At the end of the growing season, after harvesting, the trellis was removed from the plantings. In the middle between the aisles, the pristambic stakes were installed against the behind-the-bush bushes. After that, all non-crooked bushes were uprooted by the passage of the picker across the rows. At the end of the clearing, each of the stakes of the stake was planted with two (then one from the adjacent bushes) grafted vines of the FOLDER variety Riparia x Rupestris Cobbber BB. Pre-vines of varietal varieties were cut to length

140-150 cm so that after planting the height of the ground boom is about 1 m, and the place of the cut is treated with B indolyl oil-acid of 052% concentration. Planting was carried out under the hydroborer, apical part of the vines into the soil.

In the third year, during the growing season, fragments were cut and pruned on the vine of a harvested variety, rooted in this period. bush; horns, fruit vines. At the end of the growing season, after harvesting, rejuvenated bushes were pruned to reduce the load on them, leaving 10-15 eyes to the load.

During the fourth year, we completed the formation of the crown of the future bushes: sleeves, horns, replacement knots, fruit ENTs. At the end of the growing season, they were removed from the rejuvenated bushes and the trunks were attached to the prchchtakbovye rings, two each. After that, the raskorchevka uterine bushes.

Thus, the reconstruction of the plantation was completed. The new layout of the rasteshty - 30 x 2.5 m.

In a known way, all the measures inherent in it were carried out: partial shredding of the bushes through a series, rejuvenation of a partial above-ground part of the remaining bushes and annual rejuvenation of the root system.

With the initial yield of the plantation 75-80 (before the beginning of the test), according to a method known from the first year, the yield decreased to 46 c / ha in the second, third and fourth year it was within 85-94 c / ha. In the proposed method, in the first year of testing, the yield was 74 centners per hectare, and in the second, third and fourth, respectively, 95 and 1 16 centners / hectare.

Thus, the invention allows for the accelerated reconstruction of the planting of grapes, updating both the aboveground and underground parts of the bushes, not only without reducing its productivity, but also enhancing it through two-way feeding: the old

and the new root system. one

The specific features of the proposed method, the budding of the rootstock and the rooting of the rootstock, connected through grafting with a bush, allows the use of grape species that are immune to phyloxera.

Formula of Invention

A method of reconstructing a vineyard, including the uprooting of old bushes, rejuvenation of the remaining ones, cultivation of young shoots and the formation of their crown, characterized in that, in order to preserve the productivity of plantations and prolong the exploitation of the vineyard, shoots that grow after the rejuvenation of the bushes are planted with ROUTINE varieties and rooted apical ends in pairs from the two adjacent bushes in the holes located in the aisle, after being cornified, they are separated from the rejuvenated bushes, which are then removed.

Claims (1)

Claim A method of reconstructing a vineyard, including uprooting of old bushes, rejuvenating the remaining, growing young shoots and forming y. of them crowns, characterized in that, in order to maintain the productivity of the plantings and prolong the operation of the vineyard, the shoots growing after rejuvenation of the bushes are planted with root crops and root apical ends in pairs from two adjacent bushes in the holes located in the aisle, after rooting they are separated from rejuvenated bushes which then delete.
