Assortment of cereal grasses for forming lawns at landscaping sites in the Coastal zone of Southeastern Crimea

Abstract

   Lawns are integral elements of landscaping of landscape architecture objects. Rational selection of the assortment allows creating economical, long-term, highly decorative plant coverings in specific soil and climatic conditions. The coastal zone of the Southeastern Crimea is extremely unfavorable for creating lawn coverings due to low humidity, high summer temperatures, heavy low-fertility waterproof soils, salinization. The article analyzes classical and modern works on creating lawns and the range of lawn grasses in relation to the conditions of the southern arid and semi-arid regions. A basic range of lawn grasses has been developed, including 9 species and 3 forms, for creating lawns for various purposes in the coastal zone of the Southeastern Crimea. For the arrangement of parterre and ordinary lawns of class I quality with a high level of technology for creation and care, it is proposed to use grass mixtures of long-term low-lying cereals resistant to low mowing. Lawn coverings for sports facilities must be resistant to trampling and frequent mowing. They can be created from a mixture of Lolium perenne L. cultivars or a grass mixture with Festuca rubra L. ssp. rubra, F. rubra var. commutata Gaudin, F. rubra var. trichophilla Ducros tx Gaud., Poa angustifolia L., Lolium perenne L. Ordinary lawns of quality class II with a high level of technology of installation and subsequent periodic irrigation can be created from grass mixtures, the components of which are undemanding to environmental factors and resistant to negative factors. For turf covering for special purposes without irrigation and rare high mowing, cereals of local flora can be used.
