Abstract
U vinogradima se rezidba u zrelo obavlja jednom godišnje s ciljem zadržavanja željenog uzgojnog oblika. Uz rezidbu, nakon značajnijeg obolijevanja ili kraja životnog ciklusa vinove loze provodi se uklanjanje trsova. Oba agrotehnička zahvata rezultiraju pojavom velike količine biomase koju je moguće zbrinuti kroz proizvodnju energije. Dosadašnja istraživanja biomase vinove loze, kao energenta, uglavnom su bazirana na potencijalu rezidbenih ostataka. Rezultati istraživanja pokazali su da uklanjanje trsova vinova loza rezultira pojavom velike količine biomase, od 8,2 t s.t./ha (Merlot) do 9,2 t s.t./ha (Šipon) uz energetski potencijal od 136 GJ/ha (Shiraz) do 168 GJ/ha (Šipon). Vrijednosti pepela od 3,25 % (Shiraz, Šipon) do 3,42 % (Graševina), hlapivih tvari od 76,34 % (Šipon) do 84,80 % (Shiraz) i donje ogrjevne vrijednosti od 17,81 MJ/kg (Graševina) do 18,58 MJ/kg (Shiraz) ukazuju da se uklanjanjem nasada vinove loze može osigurati sirovina zadovoljavajućih energetskih karakteristika.
Abstract (english)
In vineyards, pruning is done once a year, which results in a large amount of pruned biomass. At the same time, after a significant illness or the end of the life cycle of the vine, the vines are taken out. This results in a large amount of biomass that can be disposed of by the direct combustion process. Previous research on grapevine biomass, as an energy source, is mainly based on the potential of pruning residues. The aim of this paper was to determine the mass of total aboveground biomass, fuel properties and energy potential of primary energy per hectare on selected grape varieties (Shiraz, Šipon, Merlot, Graševina). The results of the research showed that the extraction of vines results in the appearance of large amounts of biomass, from 8.2 t d.m./ha (Merlot) to 9.2 t d.m./ha (Šipon) with energy potential from 136 GJ / ha (Shiraz) to 168 GJ / ha (Šipon). Values of ash from 3.25% (Shiraz, Šipon) to 3.42% (Graševina), volatile substances from 76.34% (Šipon) to 84.80% (Shiraz) and lower calorific values from 17.81 MJ / kg (Graševina) to 18.58 MJ / kg (Shiraz) show that the extraction of vineyards can provide the raw material with good energy characteristics.
