High-density cultivation systems (HDPS) are widely adopted in grape cultivation with the aim of increasing yield, improving fruit quality, and better adapting to mechanical harvesting. This study mainly analyzed the physiological and agronomic responses of grapes under HDPS conditions, including how to optimize the canopy structure, enhance the photosynthetic effect, and the changes in fruit development. It evaluated the impact of this planting method on yield stability, sugar-acid ratio, anthocyanin content, and harvest efficiency, and discussed the integrated schemes of pruning methods and mechanized operations that are compatible with HDPS. This research provides theoretical support for achieving more precise and sustainable management of vineyards, and also offers practical references for addressing labor shortages and responding to climate change.
