Abstract

The experimental data of 2017-2019 are presented. The influence of microbiological preparations produced in the biological laboratory of the Federal State Institution “Omsk Reference Center of the Rosselkhoznadzor” on the propagation of introducers of tree species growing on the territory of the regional nature monument “Regional Dendrological Garden named after G.I. Gense” was analyzed. Improvement of the technology for growing seedlings was carried out in open ground by various methods: green cuttings, lignified (winter) cuttings and seed propagation using environmentally friendly preparations - Elena, Azolen, Trichodermin and Black Yeast. The metabolites of the producer strains of the studied preparations are antibiotics, siderophores, hormones, enzymes, nutrients (nitrogen, phosphorus, potassium). The multifaceted mechanism of action of these preparations includes a growth-stimulating effect, suppression of the development of phytopathogens by isolating enzymes and antibiotics, as well as by direct parasitization and competition for the substrate, optimization of the processes of providing plants with mineral nutrition. Their positive effect on rooting, development of the root system, an increase in the diameter of the root neck and growth has been established. The best preparations that influence the formation of larger and more developed root systems of seedlings are Black Yeast and Trichodermin. More responsive to the use of the studied environmentally friendly preparations by tree species are brittle willow, spherical (Salix fragilis) and Manchurian walnut (Juglans mandshurica).
