Abstract

Kazakhstan is an agrarian state, and agriculture is one of the main sources of the economy. The country not only provides its own agricultural production with raw materials, but also has the opportunity to export products to neighboring countries. Therefore, improving the efficiency of agriculture is one of the urgent tasks. Soil salinization is a key factor affecting the productivity of agricultural crops and creating serious obstacles to sustainable land management in arid and semi-arid regions.

Regions of Kazakhstan, characterized by a variety of ecological landscapes, are exposed to soil salinization, which leads to a decrease in crop yields and deterioration of ecosystems.

The purpose of the study is to isolate, select and identify salt-tolerant strains of microorganisms characteristic of the rhizosphere of Amaranthaceae plants growing on saline soils of Northern Kazakhstan.

The article presents the results of microbiological analysis of microorganisms selected from the microflora of Amaranthaceae plants growing on saline soils of Shortandy and Tselinograd districts of Northern Kazakhstan. The cultural and morphological characteristics of the studied microorganisms are also described. Quantitative indicators and the composition of the microorganism complex were determined, pure cultures were isolated. It was found that the microflora of the studied Amaranthaceae plants is rich in microscopic fungi, bacteria and actinomycetes.

The isolated strains of microorganisms were inoculated on solid media with sodium chloride at concentration of 1%, 2%, 3%, 4%, 5%, 7% and 10% and salt-restrain cultures were selected. As a result of the experiment, the following salt-restrain strains were identified: Sphingobacterium caeni 2P, Pseudomonas aeruginosa 25P, Halomonas meridiana 48P, Bacillus pumilus 54P, Paracoccus marcusii 58P, Sphingobacterium faecium 69P, Streptomyces europaeiscabiei 85P, Glutamicibacter halophytocola 98P, Bacillus megaterium 106P. In the future, the growth-stimulating and fungicidal properties of salt-restrain crops will be studied.
