RECONSTRUCTION OF YOUNG DECIDUOUS SEEDLINGS BRIQUETTED
This article discusses the behaviour pattern of ground vegetation and growth of pine plantations established by fifteen years old planting of containerized seedlings on prepared by scarifier soil cuttings and without preparation. Experienced seedling stands were laid down in the framework of «Taiga – Model Forest» international project by employees of the Petrozavodsk State University and the Forest Research Institute of Russian Academy of Sciences. They were laid in an old overgrown logging out of fresh green moss pine forest on podzolic illuvial Fe-rich sandy loam soils. Plant biometrics: mean stend-height is 5,24 cm, mean stend-diameter is 8,0 cm, crown development 2,3–1,8 m have stands created on prepared soil. The root assemblage of trees on the unprepared soil does not have a strong major root and have a weak roots development of all kinds orders. Also indexes of growth tension (height-to-diameter ratio) and integrated estimating index (height-to-basal area ratio) validated study findings. Based on observations and analysis of the results it was concluded that the need for soil preparing on moss forest site types for reforestation by containerized seedlings.
