摘　　要：以13年生红富士苹果为试材,探讨反光膜铺设时间长短对果实品质的影响。结果表明,果园地面铺设反光膜能显著提高苹果果实维生素C含量和着色程度,降低果实可滴定酸含量,且铺设时间越长效果越好;铺设反光膜能显著增加果实红色度,反光膜铺设时间20天时,果实着色效果最好。13-year-old Red Fuji apple was used as test material.The effect of reflective film mulching time on Fuji apple fruit quality were investigated.The results showed that reflective film mulching could significantly improve vitamin C content and promote fruit coloration,reduce the titratable acid content of apple fruit,and the longer the mulching time,the better the fruit quality.Reflective film mulching could significantly increase the redness of apple fruit,improve the red-yellow ratio of fruit.The fruit coloration was the best with 20 days reflective film mulching time.
