With the rapid development of information technology, digital village construction has become essential for promoting agriculture and rural modernization. This study thoroughly analyzes the construction and implementation of an agricultural information service system within the context of a digital countryside. By integrating theoretical research and empirical data, an efficient service system model was designed and validated, leading to significant improvements in agricultural production efficiency, product quality, and market competitiveness. The study identifies key challenges in the implementation process, including technological adaptability, user acceptance, and economic and horticulturalist factors, and proposes corresponding solutions. This study provides theoretical and practical guidance for agricultural formalization in the digital countryside, offering clear directions for relevant policy formulation and future research. The findings aim to enhance the effectiveness of digital technologies in rural areas, supporting sustainable agricultural development and rural revitalization.
