Seed potato treatment is a critical agronomic measure for enhancing emergence quality and early growth performance. This study systematically analyzed the effects of various seed potato treatment methods-including cutting, chemical disinfection, and sprouting-on emergence characteristics, seedling morphological indices, and physiological-biochemical responses. The results indicated that all treatment methods improved seed potato vigor to varying degrees; notably, the combined treatment demonstrated the best performance in increasing emergence rates and shortening the time to emergence, while also significantly improving emergence uniformity. Regarding seedling growth, optimized treatments significantly promoted plant height, leaf area expansion, and root development, while enhancing chlorophyll content and photosynthetic efficiency. Physiological analysis revealed that appropriately treated seed potatoes exhibited increased antioxidant enzyme activity, enhanced seedling adaptability to stress, and improved carbon and nitrogen metabolism. Comparative analysis highlighted the distinct advantages of the combined treatment in terms of growth promotion and practical production value. Case studies further validated that optimized seed potato treatment techniques can significantly improve emergence quality and economic returns in actual production. This study provides a theoretical basis and technical reference for the standardized treatment and high-efficiency cultivation of seed potatoes.
