APPROBATION OF MODIFIED ORGANIC BIOPREPARATIONS ON SOME PLANT TYPES OF THE ASTANA BOTANICAL GARDEN

Аннотация

Scientists of the LLP "Institute of Coal Chemistry and Technology" developed and obtained a line of modified organic biopreparations (MOB) based on the organomineral fertilizer "Kazuglegumus", in combination with such elements as NPK components (nitrogen, phosphorus, potassium), molybdenum, iron, magnesium. The resulting biopreparations have a beneficial effect on the structure of the soil, as well as improve stress resistance. Laboratory studies of the MOB line on microgreens "Cress-salad" were carried out, then subsequent field tests on biological objects in the
Botanical Garden of Astana, and an analysis of the composition of the soils before and after the tests was carried out. The most effective results from the entire line of MOBs were noted for the biopreparations "Potassium humate + NPK" and "Potassium humate + molybdenum", which manifested itself in their positive effect
both on the growth of microgreens "Cress-salad" and on the biological objects of the Botanical Garden in the field trials. It is also worth noting the biopreparation
"Potassium Humate + magnesium", which distinguished itself by its effect when used on Blue Spruce (Picea pungens). This is evidenced by the results of the analysis in the agroecological testing center (laboratory) at the NJSC “Kazakh Agrotechnical University named after. S.Seifullin”, namely, the indicators of the content of humus, nitrogen (N-NO3), phosphorus (P2O5), potassium (K2O), magnesium (Mg) have improved. The content of humus increased in 73.3% of the experimental groups,
positive results were also observed for the rest of the above indicators.
