摘要
【目的】研究果园地面覆盖PET镀铝银色反光膜对石榴果实品质的影响。【方法】以会理市铜矿村栽培的‘突尼斯软籽’石榴为材料,比较分析覆盖反光膜与未覆膜对照的果实品质差异。【结果】地面覆盖反光膜可以显著促进石榴果实的着色,提升着色面积,对树冠下层果实提高着色效果最明显。地面覆反光膜,树冠下层的石榴果汁中的花青素含量提升11.44%、总酚含量提升3.03%、总黄酮含量提升12.43%;抗氧化能力中DPPH中下层分别增加7.26%、12.89%,FRAP在上下层中分别增加3.67%、9.30%;对下层的可溶性糖提升4.58%,而对可滴定酸和TSS没有明显的影响。【结论】果园地面覆盖反光膜可以显著提升石榴树冠中下层果实品质,是生产上改良果实品质的有效途径。
【Objective】 To explore the effect of covering the orchard ground with PET aluminum-coated silver reflective film on pomegranate fruit quality. 【Method】 Fruits of ‘Tunisia soft-seed’ pomegranate cultivated in Tongkuang village of Huili city were used as materials. Fruit quality of covering with reflective film treatment and none reflective film treatment was comprehensively evaluated.【Result】The experimental results showed that the surface reflective film could significantly promote the stained area of pomegranate fruit and accelerate fruit coloring,and the effect on improving the coloration of fruit under canopy was most obviously. When the ground was covered with reflective film,the anthocyanin content in pomegranate juice under the canopy increased by 11.44%,the total phenol content increased by 3.03%,and the total flavonoids content increased by 12.43%.The antioxidant capacity of DPPH in the middle and lower layers increased by 7.26% and 12.89%,respectively,and FRAP in the upper and lower layers increased by 3.67% and 9.30%,respectively. The soluble sugar content in the lower layer was increased by4.58%,the titratable acid and TSS were not significantly affected.【Conclusion】Covering reflective film can significantly accelerate fruit qualityof the middle and lower layers of the pomegranate crown,which is an effective method to improve fruit quality in production.
