FIELD: biotechnology.
SUBSTANCE: invention represents a polyfunctional agent for plants based on bacterial strains containing a filler with a biomass of bacteria in a spore form, potassium and sodium salts of humic acids, additionally contains fulvic acid in amount of 0.2–2.0 %, wherein content of biomass of bacteria is not less than 0.6x107 CFU/ml of living microbial cells, and salts of humic acids are introduced in form of 4–6 % solution. According to the second version, a polyfunctional agent for plants based on bacterial strains, containing a filler with a biomass of bacteria in a spore form, potassium and sodium salts of humic acids, additionally contains fulvic acid in amount of 0.2–2.0 %, wherein content of biomass of bacteria is not less than 0.3x107 CFU/ml of living microbial cells, and salts of humic acids are introduced in form of 4–6 % solution. Biomass of bacteria in spore form, in particular, contains Bacillus subtilis – strain DSM 24613 (VKPM B-10641), Bacillus amyloliquefaciens – strain DSM 24614 (VKPM B-10642), Bacillus amyloliquefaciens – strain DSM 24615 (VKPM B-10643), in equal percentage ratio.
EFFECT: invention stimulates growth of plants, protects them, influences adaptability and preserves stability of their properties.
