THE MODERN STATE AND THE PERSPECTIVES OF THE USE OF SINGLE-DIMENSIONAL FLOWER-DECORATIVE PLANTS IN THE GREENING OF THE PARK ZONE OF VINNYTSIA NATIONAL AGRARIAN UNIVERSITY

Abstract

The present state of the trends of the use of annual flower-ornamental crops in the Podillya region is analyzed and their promise for landscaping of the park zone of VNAU is determined. The most promising species and varieties of the cultures of the Astra family (Asteraceae L.) were studied and investigated: Medicinal leeches (Calendula officinalis L.), Zinnia aqnustifollia H., Rootsters (Tagetes erecta L.) and Astra annalistic (Callistephus chinensis L.), – ecologically plastic plants, resistant to limiting environmental factors and with long decorative properties during the growing season. The most promising varieties of domestic selection for the creation of a collection of annual crops on the basis of the exhibition area of the Vinnytsia National Agrarian University are found: medicinal herbs (Sun of Egypt, Kabloon, Geisha), cynic of the narrow-leaved (Gloriencha, Sombrero, Classic), black-eyed peoples (Titan, Vavila, Robin Good), astera annually (Artistic, Yablunevo, Amethyst). By studying the dynamics of the flowering time of the studied varieties, it was found that the highest flowering duration (up to 60 days) was found in Tagetes erecta L. (52 days for the Titan variety, 60 days for the Vanilla variety, 55 days for Robin Good variety). Also, we have generalized recommendations on the use of different cultivars of the studied annuals of foreign selection in landscaping, taking into account their biomorphological features. It is established that from a practical point of view, they are promising for creating groups on the background of the lawn, micoborts, rabatok, flower beds and is an excellent material for the creation of monosads. It is the expansion of variants of simple and complex garden compositions with their participation will give the park area VNAU more decorative, the results of research will be used for the course of lectures and practical classes on the program of the specialty «Landscape management» for students of the Faculty of Agronomy and Forestry Vinnytsa National Agrarian University.
