| description | The analysis was conducted on the general biogenicity and phylogenetic structure of fungi in the soil microbiome
of greenhouse cucumbers grown as a monoculture and after the precursors of pepper and lettuce. The relationship
between the following indicators has been proved: the total biological activity of the soil, the species composition of
micromycetes, the development of Fusarium root rot, and yield. The effect of biological preparations based on strains
of Trichoderma viride and Gliocladium virens antagonistic fungi on the development of Fusarium root rot, nematodes
and yield of cucumbers was studied. The results of the experiment show that when cucumbers are grown after the
precursor pepper and lettuce, the development of Fusarium root rot and nematodes does not exceed critical values.
The introduction of Trichoderma and Gliocladium fungi into the soil in the form of a dry preparation with a titre 2.0 x
1010 conidia/g when transplanting plants to a permanent place at a consumption rate of 40 kg/ha increases the yield
of greenhouse cucumbers by 20-23%. The experiment is part of the study of the "soil exhaustion" syndrome and the
possibilities of overcoming it. The obtained results will serve as bioindicators that can be used for preliminary diagnostics
of the sanitary condition of degraded soils, selection of agrotechnical, breeding and protective measures of plants. |
