本研究的目的是筛选潜在的北方能源作物和作物残体的甲烷生产的适合性，并调查收获时间对不同作物的甲烷生产潜力的影响。在100- 200天的甲烷潜力测定中，作物的甲烷比产率在0.17 - 0.49 m3 CH 4kg − 1 VS（添加的挥发性固体）和25 - 260 m3 CH 4 tww −1（湿重吨）之间变化。耶路撒冷、梯牧草和草芦的潜在甲烷产量最高，为2900- 5400 m3 CH 4 ha −1，相当于总能量产量为28- 53 MWhha −1，约为2000 m3 CH 4 ha −1。乘用车运输40，000 -60，000 kmha-1。收获期对作物单位体积甲烷产量的影响差异很大，而大多数作物单位体积甲烷产量随作物成熟而增加。
The purpose of the study was to screen potential boreal energy crops and crop residues for their suitability in methane production and to investigate the effect of harvest time on the methane production potential of different crops. The specific methane yields of crops, determined in 100–200d methane potential assays, varied from 0.17 to 0.49m3CH4kg−1VSadded(volatile solids added) and from 25 to 260m3CH4tww−1(tonnes of wet weight). Jerusalem artichoke, timothy-clover grass and reed canary grass gave the highest potential methane yields of 2900–5400m3CH4ha−1, corresponding to a gross energy yield of 28–53MWhha−1and ca. 40,000–60,000kmha−1in passenger car transport. The effect of harvest time on specific methane yields per VS of crops varied a lot, whereas the specific methane yields per twwincreased with most crops as the crops matured.
