摘　　要：以玫瑰秸秆为发酵原料,在恒温30℃条件下进行批量式沼气发酵试验。结果表明,发酵历时44 d,当发酵体系出现酸化时,在微生物的调节下,pH能够很快恢复,产气未受到任何影响。当提高玫瑰秸秆的发酵总固体含量到20%时,发酵体系表现出同样的规律。玫瑰秸秆的产气潜力为305 mL/g TS,324mL/g VS。This paper studies the biogas production yield using the rose straw as raw material.The fermentation was conducted batch by batch at constant temperature 30 ℃.Fermented liquid became acidic in the fermentation of the gerbera straw but could be restored to normal quickly with the reaction of adjustment of the anaerobic microbe.The biogas yield of rose straw could not be the influence of pH value.When the fermentation concentration is 20%,the law of fermentation is same as the above results.So biogas yield of the rose straw is 305 mL / g TS and 324 mL / g VS with 44 days of anaerobic digestion.
