The effects of different proportions of vegetable waste biogas slurry combined with chemical fertilizer on soil properties and lettuce quality were compared.The results showed that the porosity,to-tal nitrogen content,organic matter content,available phosphorus,available potassium and pH of the soil increased after the application of biogas slurry,and the increase rate increased with the increase of biogas slurry dosage.Vegetable waste biogas slurry can increase the fresh weight of lettuce,and in-crease the content of chlorophyll,total sugar,reducing sugar and vitamin C in lettuce.The effect of bio-gas slurry combined with chemical fertilizer was better than that of biogas slurry alone.
