Abstract

The object of the study was silt pond No. 4 of the UE “Minskvodokanal” after the technical and biological stages of reclamation. The technical stage of reclamation consisted in applying sand pads to the surface of the silt pond with a layer of 50–60 cm and levelling the surface. The stage of biological reclamation consisted of planting tree and shrub species to determine which tree species are suitable for cultivation under these conditions.

The best survival rate in plantings created by seedlings with an open root system was observed in Norway maple (75.4%). A satisfactory survival rate above 25% was shown by such woody species as drooping birch (37.7%), large-leaved linden (30.3%), mountain ash (28.8%), and from shrubs – bladder berry (34.7%), white dogwood (23.3%), common hawthorn (41.3%), common lilac (30.7%). Low survival rate was noted in red (northern) oak (11.6%) and brilliant cotoneaster (7.3%).

Somewhat better results were obtained in the area where seedlings with a closed root system were planted. In Scots pine seedlings, survival rate was 59%, European spruce – 50%, silver birch – 27%, and black alder – 16%.

One of the reasons for the poor survival rate of trees was a long period of rainlessness with a high air temperature in May-June, which led to the drying out of the soil and a decrease in air humidity. Also, the soil-ground conditions, which have an alkaline reaction of the environment and the presence of a certain amount of toxic substances in the soil, negatively affecting plant growth, had a great influence on the low survival rate.
