The effect of biologization of growing wine grapes on the microbocenosis of a vineyard

Abstract

This article presents the results of a microbiological study of soil samples selected in the vineyard in the berry growth stage in 20162017, aimed at studying the number of bacteria of the main ecological and trophic groups involved in the transformation of soil organic matter. It is shown that the combined use of microbial preparations and grassing contributed to an increase in the number of bacteria in the rhizosphere of the grape. Thus, the greatest number of ammonifying, amylolytic and oligonitrophilic bacteria were observed against the background of bluegrass grassing: the excess of control was 2.9, 1.3 and 1.2 times, respectively. At the same time, it was revealed that in comparison with the control, the number of phosphate-mobilizing and oligotrophic bacteria was greatest in natural grassing.
