Study on Anaerobic Fermentation of Corn Stalk

This study was carried out to investigate the effects of granularities on anaerobic fermentation of corn stalk, three kinds of corn stalk granularities (9-18cm, 2-4cm and 0.6-2mm) were selected in this experiment. The main components of corn stalk fore-and-aft the anaerobic fermentation were measured, also the content of CH₄ of biogas were detected. It was found that both the corn stalk´s conversion and the biogas output of the granularities in 2-4cm were higher than the other two kinds of size, and it can reach 65.03%, 11.80ml/gTS under medium temperature condition and 59.41%, 11.4ml/gTS under normal temperature condition.
