METHOD OF CREATION OF VEGETATIVE GROUND COVER IN RECULTIVATION OF DISTURBED SOILS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of recultivation of disturbed soils, in particular technogenic wastelands. The method comprises application on the soil surface of wastes, mineral fertilisers, and sowing of perennial grasses. At that, on the soil surface the mining wastes are applied with the layer not less than 5 cm, containing calcite and/or hydrous magnesium silicate. Compound fertilisers N₇₀P₇₀K₇₀ are applied, then exfoliated vermiculite is spread with a layer of up to 1 cm with granules of up to 4 mm, a mixture of seeds of perennial plants is sown, watered and covered with a polymer film which is removed at the 5-7^th day. As mining wastes the carbonatite wastes are also used, or screened olivinite ore or serpentinite magnesite. As the seeds of perennial plants the red fescue, timothy, awnless brome, European dune wild ruttishness is used in the amount of 50-100 g/m². Watering is carried out at the rate of 5 l/m².;EFFECT: method reduces complexity of technical and biological works on recultivation of disturbed soils and planting of urban areas, wastes recycling of mining and processing complex, increasing the efficiency of formation of sowing culture phytocoenoses and their durability, accelerating the process of recultivation with creation of conditions for accelerated accumulation of elements of fertility in the disturbed layer.;4 cl, 1 tbl
