摘要

Biogas production is a way to utilise the surplus of herbage and produce bioenergy for heating and fuel. When the natural biomass of grasses is used as a substrate or co-substrate for anaerobic digestion, the main variable factor determining the biogas quality and the methane yield is the chemical composition of the substrate. The first cut of grasses is very important for the quantities of chemical indicators determining biogas production, because the biomass yield of the first cut can account for 70% of the annual biomass. Field and laboratory experiments were carried out at the Lithuanian Institute of Agriculture in Dotnuva (55 deg 24'N) to estimate two perennial grasses - cocksfoot (Dactylis glomerata L.) and tall fescue (Festuca arundinacea Schreb.) - for biogas production, with a special focus on the variation in their chemical composition when cut at the heading and flowering stages. The findings from the first experimental year showed the quality of biomass prepared for biogas production tobe better at the heading stage than at the flowering stage.
