Took the main cultivated Fuji apples in Yanyuan County as the research object, six different planting densities were set up to analyze the effects of planting density on the growth of apple trees, photosynthetic characteristics, and fruit quality. The results showed that as the tree spacing increased, the indicators such as tree height, trunk diameter, canopy size, and new shoot length all significantly improved. Low-density planting was beneficial for alleviating tree competition and promoting overall growth potential. The analysis of photosynthetic characteristics indicated that the 1.8 m tree spacing had the optimal photosynthetic rate, and the higher-density treatments increased by 20.7%, and stomatal conductance and transpiration rate were also significantly improved. In terms of fruit quality, the single fruit weight of T₄ treatment reached 195.42 g, and the soluble solids, sugar-acid ratio, and hardness of the higher-density treatments increased by 9.3%, 22.5%, and 6.3% respectively, with the best overall performance.

以源县主栽富士苹果为对象，设置6个不同栽植密度处理，分析栽植密度对苹果树树体生长、光合特性及果实品质的影响。结果表明，随苹果树株距的增大，树高、干径、冠幅及新梢长度等指标均显著提升，低密度栽植（T₆）有利于缓解树体竞争，促进整体生长势；光合特性分析显示，1.8 m株距（T₄）光合速率最优，较高密度处理（T₁）提升20.7%，气孔导度与蒸腾速率亦显著改善；果实品质方面，T₄单果质量达195.42 g，可溶性固形物、糖酸比及硬度较高密度处理分别提升9.3%、22.5%和6.3%，综合表现最佳。
