摘要: Abstract The rising price of fossil fuel and the increasing environmental concern encourage use biomasses as energy sources. Aim this study was to compare two poplar SRC vSRC (6 3 years rotation cycle) with an annual crop (maize), used for biomass production in north Italy. average 13.9 Mg DM ha −1 per year 19.2 Mg DM ha maize. consumption cultivations about 15 GJ ha year, which represented only 6% product (about 257 GJ ha year). input value maize higher (26.8 GJ ha In case, 7% content 370 GJ ha During cultivation amount 8090 kg CO 2 eq ha emitted, 6420 kg CO 26,370 kg CO Compared maize, (or vSRC) crops are interesting from energetic point view, while requires less manpower, but it has major problems related landscape biodiversity.
