The role of biologic techniques in improving the life state of flowering shrubs

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.
