This study investigates the mechanisms by which ridge cultivation and flat cultivation systems influence sweetpotato growth and yield formation. Through a comparative analysis of crop emergence, growth dynamics, canopy structure, and storage root formation under different planting methods, the study systematically evaluates their regulatory effects on physiological-ecological characteristics and yield components. The results indicate that the ridge cultivation system significantly promotes early growth and rapid canopy development by improving soil aeration and drainage, thereby increasing the leaf area index (LAI) and light use efficiency. Furthermore, it enhances the partitioning of photosynthates toward storage roots, accelerating the rate of storage root formation and boosting final yield. In contrast, while the flat cultivation system offers advantages in water retention, it imposes limitations on soil aeration and root expansion, resulting in accelerated canopy senescence during the late growth stage and lower yield stability. Analysis of physiological mechanisms further reveals that planting patterns collectively influence crop growth and development pathways by regulating source-sink relationships and soil micro-environmental conditions. This study provides a theoretical basis for optimizing sweetpotato cultivation practices and increasing yield per unit area.
