Optimization of living conditions for seedlings of flowering shrubs

Abstract

A strategically important task of nursery in the modern realities of urban development, perspectivization and greening of landscape design of urban ecosystems, is the cultivation of high-quality planting material of ornamental crops in an optimally short time. Researches on improving seedling production technology have actual and practical importance in solving these problems. Scientifically-based measures, including optimization of soil conditions by applying vermicompost obtained from sewage sludge, buckwheat husk and ash using earthworms from the family Lumbricidae, in combination with buckwheat husk ash, as well as treatment with immunomodulating bioactive substances “Mival-agro”, “Gumi”, “Lignohumate”, allowed to increase plant survival, improve biometric indicators and obtain seedlings of the 1st commercial grade with the possibility of using them for special landings (solitaire, mixborder).
