To investigate the relationship between soil microbial activity and chili pepper yield, this study conducted field experiments and employed a combination of microbiological and agronomic analytical methods to systematically evaluate the characteristics of soil microbial activity under various management practices, as well as their impact on chili pepper growth and yield. The results demonstrated that soil microbial abundance, community structure, and enzyme activity all exhibited a significant positive correlation with chili pepper yield. Microorganisms enhance soil nutrient availability by facilitating the decomposition of organic matter and the transformation of nutrients, thereby bolstering the growth vigor and fruit-bearing capacity of chili pepper plants. Furthermore, soil microbial activity indirectly contributes to yield formation by improving soil structure and water-retention capacity. The study also revealed that different cultivation management practices—such as the application of organic fertilizers and the addition of microbial inoculants—can significantly modulate levels of microbial activity, thereby influencing chili pepper yield performance. Case studies further validated the potential application of optimized microbial management strategies in enhancing both the yield and stability of chili pepper production. These findings provide a crucial theoretical basis and practical guidance for high-yield chili pepper cultivation and soil health management.
