Abstract

The key to the normal growth and development of flowering shrubs is to provide optimal living conditions in the juvenile period. Obtaining high-quality planting material in a nursery using biologized techniques is a fundamental component of their future resistance to a complex of abiotic and biotic factors. The use of vermicompost (6 t / ha) as a fertilizer base and biologically active substances contributed to the production of high-quality seedlings. The applied biologic techniques contributed to the improvement of the growth and development of flowering shrubs, which influenced the reduction of damage by pests and diseases, the formation of healthy, decorative and attractive plants. Based on the analysis of the vital state, we ranked flowering shrubs according to their prospects for use in landscape design of the territory of urban ecosystems. Promising species for landscaping urban ecosystems in terms of a set of indicators are: Berberis thunbergii DC., Chaenomeles japonica (Thunb.) Lindl.), Lonicera caprifolium L., Physocarpus opulifolius L., Philadelphus coronaries L., Sorbaria sorbifolia L., Syringa velutina L. и Weigela florida DC.

Highlights

In the greening of the modern city, the leading role belongs to flowering shrubs
The objectives of the study included an analysis of the vital state of flowering shrubs grown using traditional and biologized technology; assessment of damage to flowering shrubs by entomo- and phytopathogenic objects in an urbanized environment
For the study, flowering shrubs were used, grown according to traditional technology and using biologic techniques (vermicompost was introduced into the soil of the experimental site before planting rooted cuttings of plants - 6 t / ha, obtained on the basis of sewage sludge, ash and buckwheat husks, during the growing season, treatments were carried out with biologically active substances: Mival-Agro (0.3%), Novosil (0.1%); Fitoverm 0.2% e.c. and Alirin-B, w.p. was used to protect against harmful objects

Summary

Introduction

In the greening of the modern city, the leading role belongs to flowering shrubs. They acquire special significance in landscape design due to their high decorative and artistic value, a wide range of colors of flowers and foliage, a different and long period of flowering, a short period of formation in the initial period of growth [1, 2]. In turn, the urban environment, being a powerful stressor for the biocenosis, causes irreparable damage, detrimental effect on flowering shrubs, reducing their decorative effect, attractiveness, productivity, gives rise to non-infectious diseases, reduces the overall resistance of plants to damage by pests, phytopathogens, makes them vulnerable. For landscape design, an assortment of flowering shrubs is required, characterized by a high degree of resistance to a complex of adverse factors, adapted to growing conditions. The aim of the research is to form an adapted range of flowering shrubs for the conditions of urban ecosystems
