Abstract: Different concentrations of biogas slurry were irrigated in scale raising farms to investigate their effects on the soil environment and quality of Brassica chinensis. Compared with the normal chemical fertilizer (CK), different irrigation amounts of biogas slurry showed no effect on the soil quality. Under equal nitrogen condition, the biogas slurry used as an organic fertilizer with rich nutrient contents instead of nitrogen fertilizer, were helpful to improve quality of Brassica chinensis. Application of biogas slurry with proper dose could not only decrease the wastewater disposal in scale raising farms, but also decrease the application of chemical fertilizer and improve the quality of Brassica chinensis.

Key words: Brassica chinensis, biogas slurry, soil quality, quality
