Poškodovanost sestojev listavcev pri redčenju s klasično in strojno sečnjo : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Damage to broadleaf stands following thinning with classical and mechanized harvesting : B. Sc. Thesis - Professional Study ProgrammesPovhe, LukaRaziskava je potekala v GGE Mirna gora, KE Semič - Metlika, oddelek tri. Namen naloge je ponovna primerjava klasične in strojne sečnje ter spravila. Gre za ponovitev pred trinajstimi leti začete ... raziskave, zato smo študijo izpeljali na primerljiv način. Oddelek je bil že razdeljen na pet stratumov: dva za strojno tehnologijo, dva za klasično in eden, kjer zaradi nadaljnjih raziskav ni bilo ukrepanja. Pred začetkom sečnje smo poiskali središča ploskev in jih dodatno označili. Po končani sečnji smo popisali poškodbe in sproščenost izbrancev. Ugotovili smo 19,4 % poškodovanost pri klasični tehnologiji in 24,4 % poškodovanost pri strojni (nove, nove in stare poškodbe). Skupna poškodovanost (nove, stare, nove in stare poškodbe) pa je pri klasični tehnologiji 35 % in pri strojni tehnologiji 49,4 %. Glede starosti poškodb je pri obeh tehnologijah največ starih poškodb in pri obeh tehnologijah jih je največ na deblu. Glede sproščenosti izbrancev smo ugotovili večjo pri klasični tehnologiji. Tudi vrednosti svetlobe so višje v sestojih klasične sečnje, kar lahko utemeljimo z jakostjo redčenja. Najmanjše vrednosti svetlobe so bile v stratumu pet, kjer ni bilo redčenja in drugih ukrepanj. Primerjava z rezultati tujih raziskav nakazuje, da je v Sloveniji več poškodb pri strojni sečnji, kar je lahko posledica visokih normativov.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
