ПРОДУКТИВНОСТЬ НАСАЖДЕНИЙ И КАЧЕСТВО ВИНОПРОДУКЦИИ СОРТА ШАРДОНЕ ПРИ НЕКОРНЕВЫХ ПОДКОРМКАХ РАЗНЫМИ ГРУППАМИ ЭЛЕМЕНТОВ

Abstract

The article presents the results of many years of research on the study of the effect of non-root preparations of various composition and system of influence on the grape plant. Investigating the technical variety of Chardonnay grapes, the main attention, along with the yield, was paid to the quality and organoleptic value of wine products from infertile soil areas. The objects of research were grapes and wine of the Chardonnay variety with variants of treatment with non-root preparations (Gumel Lux, Phylloton, Agrumax). The experience of studying the effect of foliar fertilizing on the productivity of the grape plant and the quality of wine was laid in the Anapa district on grape plantations grafted on the rootstock of Berlandieri x Riparia Kober 5BB 2006 planting according to the scheme of 3x1.5 meters, the formation of a double-shouldered cordon Kazenava. The results of research in 2019-2021 showed that the treatment of grape bushes growing on conditionally suitable soil with the studied preparations of non-root action had a positive effect on the yield and technological qualities of Chardonnay grapes. The best result in yield was given by the variants treated with Agrumax and Gumel Lux -9.7 and 9.4 kg/bush, respectively. Wine materials with variants of treatment with Gumel Lux and Phylloton preparations proved to be the most extractive in the experiment, which affected the taste qualities of these samples. According to the organoleptic parameters in the year of the study, a variant of wine material from grapes treated with Gumel Lux proved to be the best.
