THE INFLUENCE OF WINTER GREEN MANURES ON THE FERTILITY OF THE SOIL UNDER THE VINEYARD

The paper presents data on the effect of phytoremediation: the use of a mixture of winter vetch and wheat as green manure [GM] and their combination with the microbial preparation Azotobacterin [AB] (GM +AB) in vineyard rows on soil fertility on piedmont carbonate chernozems. A variant with overgrowing of row spacing with segetal vegetation served as a control. The studies were conducted in 2018–2019 in the foothill zone of the Crimea in a vineyard founded in 2002, on grapes of cultivar ‘Bastardo Magarachsky’. Also, GM cultures were sown in November and plowed in May next year. It was found that 0.19–0.21 kg m–2 of organic matter dry mass got into the soil during the plowing with GM, 1.6 times more than in the control. Thus, GM leads to the accumulation of moisture in the layer 60–100 cm, 13.4% higher than the control, and an increase in pHH2O and active carbonates content within the permissible values for grapes. There was an accumulation of organic carbon by 0.31–0.45%, mobile forms of nutrients in the soil: NO3 - by 18%, P2O5 - by 3.2 times, K2O - by 39% in the 0–60 cm layer under the influence of GM

PARKS OF RECREATIONAL COMPLEXES OF SUDAK CITY

Aim. Development of optimal paths of landscaping recreational complexes South-Eastern Crimea (Sudak for example), taking into account climatic, geographical and historical characteristics of the region. Material. Green plantings of recreational complexes have been surveyed in 2015–2016: the sanatorium "Sudak" of the Ministry of defense of the Russian Federation, the area is 26 ha; the pension "Crimean spring", an area is 10 ha; the pension "Zvezdniy", an area is 3 ha; the sanatorium "Sokol", an area is 3 ha; the Tourist and recreational complex "Sudak", an area is 17 ha. Results. Dendroflora of Sudak recreational facilities includes 151 species belonging to 90 genera and 47 families. The most represented species in the following families: Rosaceae – 27 (17,9%), Oleaceae – 12 (7,9%), Pinaceae – 12 (7,9%), Cupressaceae – 10 (6,7%), Fabaceae – 7 (4,6%). The greatest form variety is possessed by representatives of the family Cupressaceae (8, or 33,0%), the pyramidal form of cypress evergreen (Cupressus sempervirens `Pyramidalis`) dominates among them. An assortment of ornamental trees and shrubs in the studied sites are quite diverse – 175 species and forms. Deciduous trees and shrubs prevail here – 60 (34,3%) and 37 (21,1%) species and forms respectively. There are 37 (21,1%) species and forms of coniferous trees and shrubs. There are 24 (13,7%) types and forms of evergreen foliage plants: shrubs – 18 (10,3%), trees – 4 (2,3%), lianas – 2 (1,1%). Main conclusions. The source of introductory material for the green construction of South-Eastern Crimea should be the representatives of families Cupressaceae, Pinaceae, Rosaceae, Oleaceae, Fabaceae those are the most adapted to the soil and climatic conditions of the region. Increasing the diversity of ornamental trees and shrubs should be achieved through the use of coniferous and evergreen plants. To create picturesque groups of plants with different emotional conten increasing the number of decorative forms (cultivars) of ecologically resistant species has been recommended
