Features of natural regeneration under the canopy of polytric pine forests of Belarusian Polesie

摘要

In article results of study of natural regeneration under a cover of Polytric pine forests on the territory of Belarusian Polesie. 10 indicator plots have been laid under the canopy of middle-aged, ripening and mature pine stands on the territory of GLHU “Miloshevichsky forestry enterprise”, GLHU “Petrikov forestry enterprise” and GOLHU “Mozyr experimental forestry enterprise”. Produced enumeration of undergrowth on survey sites with subsequent transfer of the acc ounting amount to 1 hectare. The ages, heights and conditions of each plant with groups to their viability have been determin ed. Undergrowth of birch, oak and pine prevalence under the canopy of pine stands. The largest number of young growth noted in the stand density of the parent stand between 0.7–0.8. The absence of relationship between the amount of under-growth and density of the pine stand have been identified. The structure and density of underbrush has been studied. Prevalence of buckthorn brittle was evaluate d. The underbrush is sparse and doesn’t make any influence on the growth of undergrowth under these conditions. Mosses occupy up to 85% of the total projective cover field layer in the plots. It was noted that a small fraction of the pine regrowth due to the high den-sity of the coating with moses (Polytrichum commune L.), which prevents the rooting of pine seedlings.
