magistrsko delo - 2. stopnja
Povzetek
Namen magistrske naloge je bil ponoviti meritve sadnje in analizirati spremembe, opisane v diplomski nalogi Belcla (2021), na območjih Gozdnogospodarske enote Spodnje Dravsko polje. Poleg tega smo popisali naravno obnovo in primerjali uspešnost različnih vrst zaščite mladja. Stopnja izpada vseh sadik se je med leti gibala od 21 % do 40 %. Visoko stopnjo izpada pripisujemo presaditvenemu šoku in neprimerni oskrbi sadik. Ugotovili smo, da so vse posajene drevesne vrste primerne za sadnjo, vendar so se med njimi pojavljale razlike glede na preučevane parametre. Kakovost sadik se je zaradi manjše gostote poslabšala. Glavne poškodbe sadik so bile posledica insektov in gliv ter gojitvenih del, ki smo jih označili kot problematične. Na umetno pomlajeni površini so tujerodne drevesne vrste kljub negi predstavljale 35 % drevesne zmesi. Od prve meritve se je dobro vraščal gaber in druge klimaksne vrste. Zaščita sadik se je izkazala za nujno, saj so bile sadike, zaščitene z tulci, najbolj vitalne in najmanj poškodovane. Umetna obnova se je izkazala za primernejšo kot naravna, saj je bil naravno obnovljen sestoj neenakomerno pomlajen, pri čemer so prevladovale manj tržno vredne vrste slabše kakovosti.

Analysis of planting success in forest management Unit Spodnje Dravsko polje and comparison with natural regeneration |
Sekundarni povzetek: |
The aim of this thesis was to repeat the measurements of planting and to analyze the changes described in the thesis of Belcl (2021) in the areas of the Forest Management Unit Spodnje Dravsko polje. In addition, we inventoried natural regeneration and compared the success of different types of seedling protection. The mortality of all seedlings varied from 21% to 40% between years. The high mortality is attributed to transplant shock and inadequate tending of the seedlings. All the tree species planted were found to be suitable for planting, but there were differences between them based on the parameters studied. The quality of the seedlings declined due to the lower density. The main damage to the seedlings was caused by insects and fungi and by silvicultural work, which we identified as problematic. In the artificially regenerated area, non-native tree species accounted for 35 % of the tree species mixture, despite tending. Hornbeam and other climax species have established well since the first measurement. Protection of seedlings proved to be necessary, as the seedlings protected by sleeves were the most vigorous and least damaged. Artificial regeneration proved preferable to natural regeneration, as the naturally regenerated stand was unevenly regenerated with a predominance of poor quality, less marketable species. |
