METHOD OF RECLAMATION OF SPOIL BANKS AND SITES OF INDUSTRIAL WASTE

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of forestry and reclamation. The method comprises coating the slopes with soil substrate by uniform shifting it from the horizontal surfaces, covering the horizontal sites with soil substrate by leveling, planting the nursery plants of trees and shrubs, planting seeds of herbaceous plants. As the soil substrate, a mixture of material with a high content of nutrients is used in the form of sewage sludge, organic matter, peat, manure and phosphogypsum with the ratio of the mixture components of 2:1 by volume. The mixture is stirred by milling on horizontal plate. Covering the surface of the slopes with the resulting mixture with the thickness of 25-30 cm is carried out by uniform sliding on the slopes. Then, a continuous layer with the thickness of 15-20 cm is formed on the horizontal surfaces. The layer of the soil substrate is covered on top with a mulch layer of sand with the thickness of 1-3 cm using a spreader. At the final stage of reclamation across the entire surface the nursery plants of fast-growing trees and shrubs are planted, which have the developed root system and aboveground part with the height of 0.5-1.0 m, followed by sowing seeds of herbaceous plants.;EFFECT: invention enables to accelerate biological reclamation due to creation of optimal conditions for growth of tree and shrubbery vegetation by optimising the composition of the artificial soil substrate used.;2 cl, 8 dwg
