Formation of lawn grasses on the basis of soil conservation in the park zone of VNAU

Abstract

The conducted research is devoted to biodiversity, namely soil conservation. The very use of lawn grasses as an integral aesthetic decorative element of landscape design is at the same time an ecological and ameliorating factor of influence on the surrounding natural environment, which is quite widely used not only in Ukraine, but also abroad. It has been established that a feature of improving the condition of lawn cultural phytocenoses is the use of low-lying perennial grasses and their varieties, which are maximally adapted to the edapho-climatic conditions of the Podillia zone. Dense lawn coverings trap dust, increase air humidity, improve the microclimate of the environment due to the phytoncides released by them, thereby improving the air, preventing erosion and improving the agrophysical properties of the soil. Based on the records and observations made in the conditions of the park zone of the Vinnytsia National Agrarian University, the composition of lawn grass mixtures, quality condition and density of the lawn were established. The economic and ecobiological structure of lawns is displayed. The peculiarities of the formation of lawn cultural phytocenoses based on the analysis of the qualitative state of the existing grass stand are given. The percentage ratio of the quality composition of lawn grasses has been established. The agrotechnical measures for the care of lawn cultural phytocenoses at the research site are scientifically substantiated. A summarized balance of lawn areas by quality condition is given, which makes it possible to reasonably approach the planning of agrotechnical measures.
