Lesna biomasa iz zunajgozdnih nasadov hitrorastočih vrst : diplomsko delo - univerzitetni študij = Wood biomass from outside the forest plantations of fast-growing species : graduation thesis - university studiesJemec, Tina, gozdarkaZunajgozdni nasadi hitrorastočih drevesnih vrst dajejo velik hektarski donos lesne biomase, ne posegajo v naravne gozdove in hkrati pomenijo razbremenitev naravnih gozdov. Ti nasadi predstavljajo ... pomemben vir lesne biomase za velike porabnike, kot so daljinski sistemi in večje termoelektrarne. Primerne lokacije za nasade hitrorastočih drevesnih vrst so opuščene kmetijske površinein kmetijske površine z manj ugodnimi razmerami za pridelavo živil in krme, vodovarstvena in kontaminirana območja, površine prizadete zaradi rudniške ali druge industrijske dejavnosti ali strma območja. Sečnjo v teh nasadih izvajamo vsakih nekaj let, odvisno od obhodnje. Ta je po navadi od 2- do 5- letna. Gostota sajenja je različna in je odvisna od obhodnje. Najbolj pogosto za nasade uporabljamo klone vrbe ali topola. Količina proizvedene lesne mase je odvisna od dolžine obhodnje, drevesne vrste, kakovosti tal in od intenzivnosti nege. Skupaj z Gozdarskim inštitutom smo opravili meritve na testnem nasadu v letu 2009 in letu 2010. Na podlagi obdelave pridobljenih podatkov smo prišli do ugotovitve, da skupni donos testnega nasada ne dosega pričakovane vrednosti donosa nasada navedenega v literaturi. To pa zato, ker so bili naši podatki dobljeni na podlagi enoletnega prirastka. Nasad v tem času še ni dosegel kulminacije volumenskega prirastka, zato podatki iz tega nasada še ne potrjujejo gospodarnosti tovrstnega nasada.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
