不同密植行距对'库尔勒香梨'果实色泽和品质的影响研究OA
Study on the Effects of Different Row Spacing in Dense Planting on Fruit Color and Quality of'Korla Fragrant Pear'
本研究以8年生'库尔勒香梨'为试材,调查了库尔勒香梨园的5个不同密植行距(220、280、340、420、480 cm),系统研究了行距配置对果实色泽、单果质量及综合品质的影响.结果表明,各处理间单果质量虽无显著差异,但处理T4(420 cm)冠层上部、下部果实单果质量分布最为均匀,分别为111.83 g和108.94 g;在色泽指标方面,T4处理表现出更明显的黄绿色泽、更高的果皮透亮度和更饱和的着色效果,同时其冠层上部、下部果实可溶性固形物含量分别为13.95％、13.60％,可滴定酸含量均为0.54％,表现出良好的一致性.主成分分析表明,420 cm行距处理在提升果实综合品质和外观色泽方面效果显著,其综合评分为2.295,排名第一.综上,420 cm×100 cm行株距配置的'库尔勒香梨'在果实色泽和品质表现最优.
This study utilized 8-year-old'Korla fragrant pear'trees as experimental materials to investigate the effects of five different row spacings(220,280,340,420,480 cm)on fruit color,single fruit weight,and overall fruit quality.Although no significant differences in average single fruit weight were observed across treatments,the T4 treatment(420 cm row spacing)exhibited the most uniform distribution of fruit weight between the upper and lower canopy layers,with values of 111.83 g and 108.94 g,respectively.In terms of color characteristics,fruits from the T4 treatment displayed a more pronounced yellow-green hue,greater peel transparency,and enhanced color saturation.Furthermore,the soluble solids content in the upper and lower canopy fruits under T4 was 13.95％and 13.60％,respectively,while titratable acidity remained consistent at 0.54％in both canopy positions,indicating high physiological uniformity.Principal component analysis revealed that the 420 cm row spacing treatment significantly enhanced overall fruit quality and visual appearance,achieving the highest comprehensive score of 2.295.In summary,the'Korla fragrant pear'orchard with a row and plant spacing configuration of 420 cm×100 cm exhibited the best performance in fruit color and quality.
