with peat and forest soil mixture (1:2) and one acorn per cell was placed. Germination was noticed on the start of April 2020 in seedbeds and two weeks later into containers and it was finished on the half May. Germination percent was near 50 % in both stocktypes. During growing period seedlings were ordinarily irrigated with several hand weeding. Fertilization were performed uniformly for both seedlings types during 6 weeks from middle June to middle July (Fitogal S®- Galenika, according producer prospects). Field trial – Terenski pokus Establishment site (44.777569, 20.429238) previous were planted mixed forest of pines (P.nigra and P. sylvestris) and deciduous species (Fraxinus excelsior, Tilia argentea, Prunus avium, Quercus cerris, Quercus petraea, Castanea sativa), marked as low valuable forest from several aspects. Situation on the field indicated need for sanitary logging and restoration in the aim to promote natural vegetation. Soil conditions, elevation, exposition and climatic characteristics indicated possibilities of oak forest establishment with giving priority for Q.pubescens. Site preparation was conducted after a clearcut. It included logging and removal of trees and shrubs with mechanical grinding of remains. Planting was performed in the first half of December 2020. Planting holes (30 x 30 cm) were prepared by mechanical driller several days before. Bareroot seedlings were transported in plastic bags from nursery, while containers seedlings were transported in containers. Planting sites were squarely randomized on the distance 3 m and random arrangement of different stocktype seedlings was performed during planting. Total of 408 seedlings were planted and marked accordingly to stocktype. Mechanical weed control between seedlings was provided only once – in the last week of May. |
