摘要	Experimental studies have been carried out on the quality of green silage and performance of anaerobic digestion with additives of acetic acid for maize straw silage. The results show that additives of a small amount of acetic acid do good to long-term green maize straw silage and to preventing it from getting putrid and to improving the quality of fermentation. When acetic acid percentage content is 2% of fresh weight, the ratio of holocellulose (HoC) reaches (51.20±0.45)%, the total amount of organic acid is higher to (10.92±0.30)% than other groups, which shows better quality of green maize straw silage and higher methane production potential. After 240 days green silage, the maize straw silages were mixed with cattle manure in 3:7 total solid ratio to produce biogas at 37. When acetic acid percentage contents is 4% of fresh weight, the methane production is the highest. After 70 days anaerobic digestion, the average contents of methane is 54.00%, TS gas yield rates is 312.02 L/ (kg TS) and VS gas yield rate is 470.63 L/(kg VS). © 2019, Editorial Board of Acta Energiae Solaris Sinica.
