TECHNOLOGY OF SUPPLEMENTATION OF THE MOST COMMON ETERNAL EVERGREEN TREES AND SHRUBS IN THE CONDITIONS OF VOLYN REGION

Abstract

The article describes the beneficial properties of evergreen trees and shrubs as an important and integral part of human life and our planet as a whole. Particular attention is paid to the technology of reproduction of both coniferous and deciduous evergreen trees and shrubs, namely grafting to increase their species diversity and quantitative composition, the creation of highly ornamental and environmentally sustainable greenery, as well as to reduce the growing time for modern urbogenic conditions that have become global in recent decades. The method of grafting trees and shrubs was studied, the percentage of survival and growth rates of the most common evergreen plants in Volyn were studied, in order to include them in the future for landscaping. The object of the study were evergreen trees and shrubs, namely we studied such evergreen plants as Thuja occidentalis L. «Columna», Thuja occidentalis L. «Clobosa», Thuja occidentalis L. «Ericoides», Thuja occidentalis L. «Aurea Ellvangeriana», Juniperus sabina L., Juniperus communis L. «Hibernica», Picea pungens Engelms «Glauca», Buxus sempervirens L. During the research, methods of comparative analysis and synthesis of information, observation, description, generalization were used, as well as system and field methods, mathematical and statistical method were used. Measurements and observations of cuttings planted in the greenhouse and their number were carried out and the number of rooted and planted cuttings in open ground was determined. Also, the ratio of cuttings that took root in the total number of planted cuttings in percentage was calculated and the average size of underground and aboveground parts of plants that best take root and grow in the natural and climatic conditions of Volyn region was measured. In modern conditions, which are characterized by a high degree of anthropogenic pressure on natural ecosystems, these studies are extremely important and relevant, which is due to the need to find and alternative solutions to combat these processes directly in each region of Ukraine.
