Formation of the composition of the microflora of the rhizoplane and the rhizosphere of cucumber in the coconut substrate

Abstract

The obtained results showed the formation of differences in the complexes of microscopic fungi of rhizoplana and rhyosphere in the summer-autumn crop turnover of cucumber with the secondary use of coconut mats. The results determined and showed the role of microorganisms that are part of the components of biological products, accounting for the number of which is important and necessary to ensure the existence of a controlled biocenosis of coconut substrate. In the process of microbiological studies, it has been proved that when using biological products in the community of substrate microorganisms, there is a direct connection between an increase in the number of antagonists and a decrease in phytopathogenic species. When applying biological preparations, the greatest differences in the microflora of the substrate were noted. This made it possible to more clearly identify changes in the structure of the microflora of the rhizosphere and rhizoplana of cucumber and stimulated the development of fungi such as Trichoderma spp., as well as bacteria of the genus Bacillus spp. and Pseudomonas spp. in the community. However, the revealed dynamics does not have a global scale, since the composition and structure of the dominant and frequently occurring other types of microbial communities of the control group largely coincided with the experimental one.
