Abstract:
The article provides information on the types and species of soil
algae determined from soil samples taken from the soil of vineyards and
orchards from 0-5 cm to a depth of 20-25 cm.
Key word:
Vineyard, essential garden, soil algae, species and species, gray
soil.
Cultivated soils are fundamentally different from non-cultivated
conservation lands. When soil is plowed and cultivated, its biological properties,
in particular, biogenicity, biological activity, and productivity increase. When the
soil is cultivated, the number of microorganisms in it increases, the importance
of mold fungi decreases, and nitrification processes increase. That's why we
conducted scientific research on the study of soil algae.
Processing the soil with different methods leads to a change in the order of
algae communities in it [1; 389-399.]. Algae of cultivated soils are very dynamic,
therefore there are many similarities in the flora of algae in different
geographical regions. To date, there is information in the literature about the
effect of soil cultivation: plowing, cultivation, fertilization, application of various
insecticides, land reclamation, and even cultivation on the composition of algae
flora and their development. First of all, this is manifested in the composition of
algosinusia of each crop [2; 212-215.]. It was studied that the types of
cyanobacteria and algae in the vineyards and orchards designated for research
consist of the following species. 58 species were identified from vineyard soils,
which made up 30% of the total species (194) in the fields where algological
research was conducted. In Almazor soils, this indicator is 24.21%. In the
taxonomic structure, the shares of cyanobacteria and green algae have the same
index. The number of species of diatom algae in Almazor soils made up 37.0% of
the species identified from this place. In vineyard soils, this indicator is 24.14%.
[3; 47.]. Cyanobacteria took the first place with 37.37 percent more than others
in field soils where algoflora was studied. A similar figure is 33.68% of diatom
algae. These two comprise 71.05% of the total algoflora. Green algae make up
24.73% of the total algoflora. Among the groups of algae, representatives of the
department Xanthophyta make up only 4.21%.

The analysis of the given numerical data shows that the maximum
conditions for the development of algae do not exist in the perennial vineyard
and mulberry soils without irrigation in the one-year wheat field. Contrary to
this situation, soil fertilization and moisture preservation in cotton fields and
alfalfa fields allow the development of algae groups. This situation increased to a
maximum during the summer when the temperature and humidity were
sufficient. [4; 232-236, 5; 98-101.].
The general list of algae found in vineyard and orchard soils was unique for
both fields. The samples include
Merismopedia tenuissima, Gloeocapsa punctata,
Nostok linckia
f
. muscorum, Phormidium foveolarum, Ph. frigidum, Lyngbya
martensiana f. edaphyca, Chlorococcum humicola, Chlorella vulgaris,

developed well. For diamond
soils,
Nostoc commune f. sphaericum, Anabaena cylindrical f. hollerbachiana,
Phormidium incinatum, Ph. corium, Chlamydomonas globosa, Pinnularia silvatica
and others became characteristic. 13 species were identified in samples of
vineyard soil below of its plowed layer.
Conclusions, the soil algoflora of the vineyard and essential garden soils kept
almost similar species and species. The reason for this is that the almost
identical agrotechnical measures and the lack of irrigation have led to the
development of less number of algae cells. 11 types and species were identified
under the plowed layer of essential garden soil. For its soil,
Nostoc commune f.
