Increase survival and development of groving grapes by use of the biopreparation on the basis of an endomycorrhizal fungi

Abstract

Objective. To study the effect of mycorrhizal preparation "Rizomax" on the basis of an endomycorrhizal fungus Glomus sp. on the growth and development of the root system of the grape plant.Methods. The studies were conducted from 2016 to 2018. The influence and aftereffect of mycorrhizal drug on the root system and growth of the grape bush were studied in the Eastern viticultural district of the South Coast zone of the Crimea. The studies were carried out according to the generally accepted methods used in viticulture.Results. The advantage of introducing mycorrhizal preparation when planting in the zone of the root system is established, in this regard, more intensive growth and root formation occurs, as well as the growth and development of the grape bush improves. The influence of the aftereffect of the studied preparation on grape plants is estimated, it is established that in experimental variants the development of plants occurs more intensively. Due to symbiosis, the grape plant more effectively uses moisture and nutrients accumulated in the mycelium, which is reflected in the improvement of phytometric indicators and high aging of the vine.Conclusions. When conducting studies in 2017-2018, to study the aftereffect of the mycorrhizal preparaion "Rizomax", in the experimental version, a stable excess of growth processes by 38.3% 43.8% and the leaf surface of the bush by 34.5% 41.7% over the control version was established. The ratio of different fractions of roots in the experimental version compared to the control is more favorable. The fouling part of the root system is 2.53 m according to the measurements of the roots, you can see how much soil the roots of the grape bush covered, that is, in the experimental version, the absorption capacity is higher. Well-developed root system and leaf surface provide further, high productivity of grape bushes. Therefore, for good plant nutrition, it is important to maintain a correlation between the root system and the leaf surface.
