<P>In order to study in the field of fermentation to produce biogas with<I>Conyza canadensis</I>, the anaerobic batch fermentation experiments were performed at 30°C. The results indicated that the net biogas production of the experimental group during total fermentation time of 36d was 3280ml. Further, it was calculated that the biogas production potential of<I>Conyza canadensis</I>was 354ml·g<SUP>-1</SUP>TS or 413ml·g<SUP>-1</SUP>VS.</P>
