STRUCTURE AND TAXONOMIC ANALYSIS OF SOIL ALGAE STEEP AREAS OF NORTHERN FERGHANA IN WINTER
Abstract: The article analyzes the distribution of soil algae in winter soils in tropical regions of northern Fergana. The first 77 species of soil algae were detected and their taxonomic analysis was performed. Algoflorada contains 4 species of algae (Syanophyta, Xanthophyta, Bacillariophyta, Chlorophyta).
Keywords: algoflora, taxon, tour, northern Ferghana valley.
Introduction
The northern Ferghana valley extends from west to east 130 km, from north to south, from 35 km to 80 km. The area is 7.4 thousand km2. The region ranks first among the Ferghana Valley regions. The north and northeast are bordered by the Jalal-Abad and southern-western regions of the Republic of Tajikistan from the southern Khujand region of the Fergana region of the Republic of Tajikistan and the Andij an region to the east.
A. M. Muzafarov (1965), A. E. Ergashev (1974), M. A. Kuchkarova, S. X. Halilov (1976), A. E. Elmuratov (1991), X. A. Alimjanova (2008) and others have been devoted to the study of water basins algae and research on soil algae has not been carried out so far.
At present, one of the pressing issues is stabilization of the balance between nature and society, the identification of soil conditions, the study of soil microorganisms, detection and distribution of soil microorganisms, and the assessment of their ecological and sanitary condition. First of all, it is important to identify and analyze the current composition of soil algae in the northeastern Fergana valley, to make a general list of soil algae of Uzbekistan, as well as to evaluate local biodi-
Research area and methods
During the research, laboratory analyzes were carried out, statistical methods and methods were used in general algorithm. The low plain of the western and eastern regions of the northern Ferghana Valley received soil samples from 10 monitoring points at altitudes ranging from 400-450 m to 1700-2800 m above sea level. A total of 20 soil samples were obtained for taxonomic and quantitative study of soil algae. Samples of soil samples were obtained from 0-3 cm of the surface and 3-30 cm deep. Algorithmic detectors, monographs, and Gollerbax M. M., Polyanskiy V. I. [1] (1951) was used. The composition of the types of the collected algorithms was determined and analyzed in the Laboratory of Microbiology and Algaology of the Botanical Institute of the Academy of Sciences of the Republic of Uzbekistan.
Analysis of the results
During the winter months of the northern Ferghana valley, 77 species and species (51 varieties of 2 varieties and 24 forms) were detected in the soil algae. They consist of 8 classes of 12 classes in 4th grade families with 32 families (Table 1).
