摘要： This study investigated the effectiveness of manure-based slurry film (MSF) technology and validated its dual benefits in reducing mineral fertilizer input and enhancing fertilizer use efficiency through field experiments. The results showed that MSF maintained silage maize yield while reducing mineral fertilizer input by 30%, and achieved a significant yield increase under 15% reduction in fertilizer input compared to standard polyethylene film. An investigation of soil microorganisms demonstrated that MSF changed the microbial community structure, promoting the activation and use efficiency of nutrients such as nitrogen, phosphorus and potassium, while increasing soil organic matter content. Life cycle assessment was performed with SimaPro 9.5 revealing that the environmental impact of MSF is significantly greater than that of polyethylene film across various environmental assessment factors. The high environmental impact of MSF production stems from its energy and water consumption, necessitating a focus on process simplification while maintaining high yield. This study provides new insights into the development of cleaner technologies, examines diversified uses of cow manure, emphasizes the role of MSF in reducing mineral fertilizer application, and highlights potential environmental risks.
