Application of bacteria strains of the genus Bacillus in picking strawberry rosettes

In production experiments in the period 2014-2017, carried out in the production nursery of the agricultural artel "Gardens of Siberia" (Novosibirsk region), the introduction of strains of saprotrophic bacteria of the genus Bacillus into the soil had an adaptive effect on plants, increased the survival rate of rosettes of wild strawberries during wintering by 14.9-21.8% relative to control. A practical growth-stimulating effect on rosettes has been proven in the B. subtilis strain VKPM V-10641 and the experimental biological product Fitop 8.67: 24-29% more young leaves than in control; the length of the root system of plants significantly increased by 9.4-13.5%; total plant biomass – by 42.5%. The effect of improving the commercial quality of seedlings grown from picked rosettes under the influence of the B. subtilis strain VKPM V-10641 and the biological preparation Fitop 8.67 has been proven to be 35.2 and 28.2% higher than the control, which significantly exceeded the effect of the reference humic preparation Phoenix, 0.05 %. Under the influence of treatment with the B. licheniformis strain VKPM B-10562, the number of standard seedlings reached 63.7%, or 21.1% higher than the control, at the same level as the standard. The use of saprotrophic bacterial strains was at the same efficiency level as for the B. licheniformis strain VKPM V-10562 or at a higher level of efficiency for the B. subtilis strain VKPM V-10641 and the drug Fitop 8.67, in comparison with the humic standard Phoenix, 0.05 %, which indicates the prospects of their use in the technology of growing seedlings from pickled strawberry rosettes.
