MICROBIAL PREPARATIONS AS A FACTOR OF GROWING PRODUCTIVITY AND PRODUCT QUALITY OF MUSCAT WHITE GRAPES
Viticulture - is a perspective economic sector in the light of the import substitution. It's necessary to identify new, biologizing methods of growing grapes, including the use of biological preparations and phytomeliorants. Use of microbial preparations enhances growth and development of grapes. Sod between rows by perennial grass to prevent soil degradation, restore soil fertility due to replenishment of organic matter. Biological preparations, created on the basis of effective strains of soil micro-organisms, are used for the cultivation of various crops, but in the vineyards they are used rarely. There are some studies of this issue. Therefore, the aim of research was to determine the effect of microbial preparations Diazofit, Phosphoenteryn and Complex of microbial preparations (CMP) on the background of sod between the rows of the vineyard by perennial grass (naturally growing grass and the mixture of cereal and legume herbs) on the yield and quality of grape variety Muscat white in terms of the Crimea. To achieve this goal in the vineyard of LLC "Adam plus" field experiment was laid. The yield of grape plants was determined in the experimental plots. The quality of the wine materials was determined in laboratory conditions. It is shown that under the influence of elements of suggested agricultural technologies contributing to the overall increase in the yield of plants per hectare (8%), sugar content increases (2.2%) and acidity of wine reduces (2.7%). Thus, we can conclude that the use of the offered elements of cultivation the vineyards by biologizing technology enhances yields of Muscat white grapes, as well as improves the quality of grape must. It is shown that the largest increase in all indicators observed on the background of cereal and legume herbs mixture that is due to the influx of large amounts of fresh organic matter to the soil of the vineyard
