Abstract

This invention relates to the field of ecology. The purpose of the invention is to obtain a durable coating suitable for biological recultivation. The composition contains, in wt%: lignosulfonate 1.00-2.50, carbamide 1.00-3.00, polyacrylamide 0.25-0.75, lime slaked (powder) 0.30-0.50, chloride calcium 0.02-0.05, water the rest. The composition is better to apply on wet ash. Moist ash, coated with a composition, gives a more durable coating and requires less blend. 1 tab.

The invention relates to ecology and can be used for the rapid elimination of dust from ash dumps in combination with phytomelioration.

The purpose of the invention is to obtain a durable coating suitable for biological recultivation.

Example. The mixture is prepared in any convenient container by successively dissolving the components of the composition in water in an amount determined by the area of the ash dump at the recommended consumption rate of 1 t / ha. For this, 94.95 mac. waters with a salt content of 1.6–2 µeq / l, dissolve 0.5 wt.h. AMP polyacrylamide, then 0.05 wt.h. Calcium Chloride 2.0 mAh of carbamide, 2.0 mAh.h. lignosulfonate and only then 0.5 parts by weight. the lime

Moreover, if the dissolution sequence is disturbed, the solution of the resulting composition coagulates. The mixing of the components of the solution is carried out using a circulation pump. The resulting composition is applied to the surface of the ash dump using an airplane. In this case, it is better to apply the composition to the wet ash, since the resulting protective layer prevents the inner layers from drying out and creates favorable conditions for the germination of the seeds, while the wet ash, which is coated with the composition, gives a more durable coating and requires a smaller amount of mixture.

The components of the composition interact with the active substrate (ash), due to which a whitish coating is formed, which prevents the sun from excessive heating of the ash with a thickness of 0.07-0.1 mm, which withstands pressures up to kg / cm.

The resulting coating withstands the autumn rains, persists for 92 days, and leaves in good condition under the snow. In the spring after that snow cover is maintained.

Experiments based on the cultivation of white clover, giant hair, yellow alfalfa, wheat, millet, and oats on pure ash and on a developed coating showed a more intensive growth in the variant with a film-covered ash. Thus, out of 100 seeds of wheat, sown on pure ash, 72 shoots were obtained, the average height of which was 12 cm a month after sowing, and 84 shoots under the cover, the average height of which was 19 cm at the same time.

The tested formulations and the results of their use are presented in the table.
