Abstract
Biological reclamation is used to restore technogenically disturbed landscapes. Plant characteristics are important when choosing a plant assortment for the restoration of degraded areas. The purpose of this work was to study the principles and methods of creating artificial vegetation cover on disturbed industrial lands. Before carrying out biological reclamation, the surface was finished and a layer of potentially fertile soil layers with a capacity of at least 1 m and a fertile soil layer with a capacity of at least 0,5 m was applied. Before starting work, the quality of the seed material and its value were determined. Soil improvers (sapropel, latex, microorganisms, cellulose mulch) and biologics (TOP organic, complex of rhizospheric bacteria, hydrogel) were used for planting herbaceous and woody shrubby plants. After carrying out the hydraulic sowing activities, field germination of the seed was monitored every 10 days. Aerial photography was performed with an RGB camera using unmanned aerial vehicles of the DJI Phantom 4 Pro+ model with an on-board Global Navigation Satellite System receiver installed. It was found that the use of a biological product based on a complex of rhizospheric bacteria activated the processes of seed germination in experimental plots. Such activation made it possible to obtain productive bushiness of perennial crops in the early stages, due to which the area of vegetation covering the experimental site increased. The addition of hydrogel and TOP organic with a weight of 2 kg also had a positive effect on seed germination and plant survival. A comparative analysis of all experimental parameters revealed that the most effective projective coating of the site was obtained with the combined use of hydrogel and the preparation TOR-organic. At the same time, a further increase in the mass fraction of hydrogel in the substrate does not significantly affect the result of the creation of artificial vegetation cover on disturbed industrial lands.
