Abstract: Livestock and poultry manure digested biogas slurry was used to prepare formulated biogas slurry fertilizer which was applied onto chilli pepper（ Capsicum annuum） to observe its effect on the photosynthesis and yield of chilli pepper,and compared with the blank and conventional fertilizer. The results show that the formulated biogas-slurry fertilizer significantly improved and promoted the photosynthesis and yield of the chilli pepper,which varied to different extents with the increase in the concentration of the biogas-slurry fertilizer. When dressed with the biogas-slurry fertilizer at the concentration of 30% the chilli pepper leaves contained the highest chlorophyll,8. 57% higher than that of the conventional inorganic fertilizer,and their net photosynthesis rate（ Pn）,stomatal conductance（ Gs）,intercellular CO2 concentration（ Ci）,transpiration rate（ Tr）,water utilization efficiency（ WUE） and stomatal limiting values（ Ls） showed no evident increase as compared to those of the conventional fertilizer. The chilli pepper dressed with the biogas-slurry fertilizer yielded 8. 70% higher than that dressed with the conventional fertilizer,which was significantly different. This indicated that the biogas-slurry fertilizer is a good liquid fertilizer in agricultural production.
