摘　　要：为探讨NaHSO3对套袋红富士苹果果实产量和外观质量的影响,以7年生盛果期红富士苹果树为试材,进行了叶面喷施不同浓度的NaHSO3试验。结果表明,与对照相比,喷施NaHSO3的各处理单果重、叶片光合色素含量、果实产量、果形指数、着色面积和硬度均有所增加。其中,喷施10 mmol/L NaHSO3对于改善套袋红富士苹果的外观质量、提高果实产量最为有效。The different concentrations of sodium bisulfite solutions were sprayed on the leaves of 7 - year - old Red Fuji apple trees during full fruit periods to study the effects of sodium bisulfite on fruit yield and appearance quality of bagged apple. The results showed that the foliage spraying sodium bisulfite had some- what increased the weight of single fruit, photosynthetic pigments content in leaves, fruit yield, fruit shape in- dex, red area percent and hardness of fruits, compared to the CK. The treatment with 10 mmol/L sodium bi- sulfate had the best effects on the fruit appearance quality.
