grape plant to make unproductive expenditures, created by them plastic substances and let them not for the formation of the harvest, but for the renewal of the sleeves. From the above even a brief analysis, it is clear that the approach to vine plant formation in traditional formations from a biological point of view is far from ideal and requires a deep rethinking. III. C onsideration of O ptions for S olving the P roblem in nature grapes are multimeter liana, then let it remain, fully realizing its biological potential, and by shaping measures we should make it technological in care and harvesting. This approach was implemented in a new innovative shaping called "Liana-like method of shaping grapes". For this method a patent under number 2535734 registered in the State Register of Inventions of the Russian Federation on October 16, 2014 [6]. The method is carried out as follows. At the first stage, during 3 years after planting, initially two non- branching shoots are formed on the grape plant (figure 1). For this purpose, growth of all stems on current year shoots is strongly limited (no more than 3 leaves), and development of shoots on perennial wood is not allowed at all. Steps on shoots of the current year, up to half of its length, are removed in late autumn. The remaining stepchildren in the following spring and in June are subjected to strong growth-limiting formation, and as the habitus of the next year's growth increases, they are to be gradually removed. By early July, all stems on the previous year's growth should be completely removed. From the 4th year, the second stage of formation of vines-like sleeves begins (Figure 2). For this purpose, four zones are distinguished and formed on each arm. The lower perennial part of the arm (older than one year) is called the first zone or reserve zone. Its habit increases every year, which ensures the growth of biomass of above-ground and regular underground parts of the grape plant, which allows to form a powerful plant with much higher productive potential than in traditional formations.
