In order to study the physiochemical properties of different parts of chili stalks and their biogas production potentials during anaerobic digestion, chili (Sujiao16) was used as the raw material. The biomass, physicochemical properties and the biogas production of different straw parts of Sujiao16were conducted at bench scale. Results showed that straw yield of Sujiao16was up to 21 t/hm2, and the ratio of chili plants biomass to chili yield was 0.36. Different parts of Sujiao16 straw had significant (P<0.05) effects on physicochemical characteristics and biogas production, with the order of leaves (185.2mL/gVS) >stem (104.2mL/gVS) >root (68.9mL/gVS). The relative content of fiber and carbohydrate of different parts of Sujiao16stalks had strong impacts on the biogas production potential of the whole straw. According to the theoretical biogas production based on molecular formula, the biogas production potential of Sujiao16was evaluated, indicating that the bioconversion rates of different straw parts were relatively low during anaerobic fermentation. Thus the reasons needed to be studied in the future.
