Abstract: Study of farmland disposal volume of biogas slurry and its effect on peppers yield, quality and soil fertility during the production in greenhouse were investigated through a field plot experiment. The results showed that biogas slurry could be a substitute for chemical fertilizer that applied in pepper production system, the yield of pepper in the treatment with biogas slurry amount equivalent to 2-3 times of the chemical nitrogen fertilizer was similar to the yield in the treatment with conventional chemical nitrogen fertilizer. Moreover, quality of pepper was improved, and the chemical fertilizer and cost could be saved. Furthermore, the application of biogas slurry farmland disposal also significantly increased soil organic matter, total nitrogen, available nitrogen, available phosphorus and potassium content. The recommendation amount of biogas slurry was 900 t·hm-2[i.e., nitrogen 530.6 kg·hm-2 (three times more than the conventional mineral nitrogen fertilizer), P2O5 37.8 kg·hm-2, K2O 311.4 kg·hm-2, COD 900 kg·hm-2] in greenhouse pepper production system.

Key words: biogas slurry, farmland disposal, pepper, yield, quality, soil fertility
