摘　　要：设计对照组(120 m L接种物)和试验组(120 m L接种物+71 g空心莲子草),采用全混合批量式发酵模式,在中温30℃的条件下,进行沼气发酵试验,研究空心莲子草(Alternanthera philoxeroides Griseb.)的产沼气潜力。结果表明,试验组的沼气发酵历时27 d,净产气量为3 080 m L。由试验结果计算得出,空心莲子草的TS产气潜力为319 m L/g,VS产气潜力为403 m L/g。In order to study the potentials of biogas production with Alternanthera philoxeroides,the anaerobic batch fermentation were divided into the control group （120 mL inoculum）,the experimental group （120 mL inoculum and 71 g Alternanthera philoxeroides） and performed at 30 ℃.The results showed that the net biogas production of the experimental group during total fermentation time of 27 d was 3 080 mL.The biogas yield of Alternanthera philoxeroides was calculated as 319 mL/g TS or 403 mL/g VS.
