Our research work is aimed at developing effective technologies for the use of Bioorganicfertilizers in forest nurseries of the Aksaу branch of RSI “Ile-Alatau state national natural Park”. The scientific novelty of this article, for the first time stabilized the technology of bioorganic fertilizers in thecultivation of seedlings of tree plants and seedlings of forest nurseries of the Aksai branch of the RSI “IleAlatau State National Natural Park”. The quantitative composition of the main ecological-trophic groupsof soil microorganisms of the upper and lower forest nurseries of the Aksai branch of RSU” Ile-Alataustate national natural Park “ has stabilized.Purpose of research – study of the technology of using bioorganic fertilizers for forest nurseries of theAksay branch of the RSI “Ile-Alatau State National Natural Park”.As a result of the study, it turned out that the length of apricot growth (Prunus armeniaca) in theundergrowth phase increased by 25% in the form of treatment with the PGPR «BioEcoGum» preparation compared to the control form, and increased by 37% in the phase of mass opening of leaves. The growthlength of Sivers apples (Malus sieversii) in the phase of sprout formation compared with the control formshowed an increase in the form of treatment with «BioEcoGum» PGPR by 32.0%, with a leaf openingphase of 29%.Key words: bioorganic preparation, PGPR bacterium, Microbiology, soil, humus.
