This study investigated the effects of canopy structure optimization on yield performance and fruit quality of ‘Taishuu’ sweet persimmon. The tree growth characteristics, canopy formation patterns, and canopy regulation requirements under different cultivation conditions were analyzed, with particular emphasis on the effects of canopy optimization on shoot distribution, flower and fruit development, fruit set, yield formation, fruit coloration, sugar accumulation, flavor, texture, and nutritional quality. The analysis indicates that a rational canopy structure can promote yield stability and improve fruit quality by optimizing light distribution and ventilation within the canopy, enhancing leaf photosynthetic capacity and light-use efficiency, improving assimilate transport and source–sink allocation, and coordinating vegetative and reproductive growth. In practical production, differentiated canopy management should be implemented according to tree age, planting density, and tree vigor, in combination with water and fertilizer management, flower and fruit load regulation, and rootstock-mediated vigor control. Future research should further improve canopy structure evaluation systems, deepen understanding of the mechanisms linking canopy regulation with fruit quality formation, and integrate technologies such as LiDAR, unmanned aerial vehicles, three-dimensional reconstruction, and digital decision-making to establish precision canopy management systems, thereby providing a theoretical basis and technical reference for high-quality, efficient, and sustainable production of ‘Taishuu’ sweet persimmon.
