Abstract: The paper aims to reduce the environmental pollution caused by farm sewage, and explore its resource utilization mode. We studied the effects of cattle farm sewage on lily’s agronomic traits, yield, quality and soil physical and chemical properties by replacing chemical fertilizer for green production of lily after harmless treatment. The results showed that: the twice application of cattle farm sewage (20.2 m3/hm2 every time) as additional fertilizer at lily bud stage replacing chemical fertilizer could promote lily growth, increase the root length, commodity rate, total sugar contents of lily, and enhance lily bulb yield by 12.0% to 24.1 t/hm2; although different additional fertilizer applications had no significant influence on soil physical and chemical properties, the application of cattle farm sewage (20.2-31.3 m3/hm2 every time) could encourage soil microbial carbon and nitrogen. This study indicates that cattle farm sewage after some decontamination treatments can be applied as additional fertilizer during green production of lily for both medicine and food use, which can not only take full advantage of nutrients in cattle farm sewage, but also improve lily’s quality and soil microbial biomass.
