This study summarizes the effects of different planting densities and canopy structures on the yield and quality of Changshan Huyou. The research results show that low-density cultivation can improve light conditions and contribute to the enhancement of fruit quality, but the yield per unit area is relatively low. High-density cultivation can significantly increase the yield per unit area in the early stage, but it is prone to overly dense canopies, which leads to a decline in fruit quality and also increases the risk of pests and diseases. Medium density shows a good balance between yield and quality. Reasonable canopy management can improve the distribution of light, promote the accumulation of nutrients such as sugar and vitamin C, and also enhance the appearance and flavor of the fruit. This study aims to provide references for the scientific management and industrial upgrading of Changshan Huyou orchards.
