20.500.12556/RUL-69650 Vpliv redčenj na razvoj bukovih sestojev na Somovi gori Thinning effects on the development of beech stands in the Somova gora research object V prispevku je prikazan razvoj bukovih sestojev, njihove reakcije na redčenja različne jakosti ter primerjava redčenih in naravi prepuščenih bukovih sestojev. Na raziskovalnem objektu Somova gora (Gozdnogospodarsko območje Kočevje, GE Željne-Laze, oddelka 43 in 40, montanski bukov gozd, Enneaphyllo-Fagetum) od leta 1980 spremljamo razvoj bukovih sestojev, ki so sedaj v razvojni fazi drogovnjak, nastali pa so z oplodno sečnjo pred približno petinosemdeseti leti. Opravljene so bile štiri meritve (1980, 1986, 1989 in 1993) ter redčenji (1980 in 1991). Učinki redčenj so evidentni in se kažejo v debelinskem priraščanju dreves, rastnem pospešku, debelinski strukturi, številu drevja, vrednostni podobi gozda, pokrovnosti zeliščnega sloja ter velikosti in sproščenosti krošenj. V redčenih sestojih izbranci bolje priraščajo kot ostala enako debela drevesa. he article presents the development of beech stands and their reactions to different thinning intensity, and the comparison of thinned and unthinned beech stands. The development of beech stands in the Somova gora research object (Forest Enterprise Kočevje, Forest Unit Željne-Laze, compartments 43 and 40, mountain beech forest on carbonate; Enneaphyllo-Fagetum) bas been examined since 1980. The stands are now in the developmental phase of pole-stand and were formed by shelterwood cutting some 85 years ago. Four measurements have been carried out (1980, 1986, 1989, and 1993), and the stand was thinned in 1980 and 1991. The effects of thinning are evident and can be obse1ved in diameter growth, timber production, diameter structure, tree-number, stand quality, covering rate of herb layer, and crown characteristics. The diameter increment of crop trees is higher than the diameter increment of other equally thick trees. izbiralno redčenje bukovi sestoji učinek redčenj struktura sestoja drogovnjak izbranci thinning beech stands pole-stand crop trees thinning effect stand structure true false false Slovenski jezik Angleški jezik Neznano 2015-07-10 21:33:40 2015-07-10 21:33:40 2024-08-10 03:59:06 0000-00-00 00:00:00 1994 0 0 Str. 85-106 [Št.] 44 1994 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*24:630*17(Fagus silvatica) 0351-3114 934 Bon¦Źina_A._44.pdf Bon¦Źina_A._44.pdf 1 DEE848C87CFAF6CCE562A07E29C8871C 5204bfa4fc9fb27c1d19c2b0693f909660acaf98fbbed40c5d510388ad6695c1 69732950-a1b3-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=100855 Biotehniška fakulteta 0 0 0
