Abstract


Dendroflora of green hedges at the University is presented with Buxus sempervirens, Syringa vulgaris, Paeonia suffruticosa, Carpinus betulus, Corylus colurna, Ligustrum vulgare, Juniperus virginiana, Thuja occidentalis that have been planted along the paths and for side border of low stairs, lawns and flower beds, for different areas fencing from wind, dust, gases, urban noise, outbuildings masking and others. The 15-20-year plantings of borders, green hedges and living walls that had been planted on the territory of the University of Horticulture to improve the aesthetics, decoration and functionality of the area were studied. The inventory and analysis of the current state of green hedges were done. Such types of green hedges as borders, green hedges, and green walls mainly composed of Carpinus betulus, Buxus sempervirens, Juniperus virginiana were selected by the height. A project of ecological principles to improve green hedges was developed. It was found out that green hedges are characterized by compositions expressiveness which forming duration depends on the participation of ornamental trees and shrubs in the planting. Silhouettes of separate planted trees solitaires acquire the expressiveness with age. Shrubs and short-lived trees gradually die. A great number of green hedges is in poor state. Such measures as forming cutting, new plants adding, application of agrotechnological measures to improve decoration will be effective for their preservation and renewal. It was offered to enrich green hedges with Ailanthus altissima, which is a priority type in the list of woody plants most suitable for making all types of green plantings in the Right-Bank Forest-Steppe of Ukraine as green hedges of Carpinus betulus, path plantings and landscape groups using Picea pungens (Engelm.), Spiraea x vanhouttei (Briot) Zab., Spiraea japonica L.). Using of Ailanthus altissima in ornamenting the University, gardens and parks is primarily caused by its valuable decorative qualities.
