Використання тропічних і субтропічних рослин в озелененні мегаполісів

Abstract

One of the promising areas of landscaping is container. The use of plants in containers in the central part of the city will create landscaping in areas where trees and shrubs cannot be planted directly into the soil. Perspective, in this regard, is the use in landscaping in the frost-free period of tropical and subtropical plants. This method does not solve the problem as a whole, but it can be a great original addition. The aim of this work was to analyze the participation of tropicogenic flora plants in the landscaping of the city of Kryvyi Rih and to identify perspectives for greening of metropolitan species from the collection of tropical and subtropical plants of the Kryvyi Rog Botanical Garden of the NAS of Ukraine. Surveying of the city's greening showed that the use of subtropical and tropical plants as a container container during the warm period is quite limited, and the single facts of their use in containers are revealed. For these purposes, plants of Chamaerops humilis L., Agave americana L., Brugmansia suaveolens (Humb. Et Bonpl. Ex Wild.), Chlorophytum comosum (Thunb.) Baker., Chlorophytum comosum 'Variegatum', Nerium oleander L. varieties were used. In the presence of extremely rich collections of tropical and subtropical plants in the botanical gardens of Ukraine, there is an opportunity to significantly expand this list. The Kryvyi Rih Botanical Gardens protected soil collection has 988 taxa. Based on study of plant biology, the collection identifies and identifies species that are appropriate for landscaping metropolitan areas by planting them in portable containers, and some of them directly into the soil as accent plants. When selecting plants for landscaping in the open ground it is important to take into account the features of their stay in the winter in the halls or greenhouses (temperature and light modes).
