本试验研究了不同类型的商品果袋在沙田柚幼果期套袋后果实品质的变化。结果表明，套袋显著地改善了柚果的外观品质，防病虫效果显著，并使单果重明显增加。虽然套袋使鲜果的可溶性固形物和维生素C的含量略有下降，但贮藏后的果实风味更佳，其中以B型果袋对提高沙田柚果实商品价值较突出。 In this study, the fruit quality of different types of commercial fruit bags after sacking in Shatian pomelo was studied. The results showed that bagging significantly improved the appearance quality of pomelo fruit, significantly prevented pest and disease and significantly increased fruit weight. Although bagging made the content of soluble solids and vitamin C in fruit slightly decrease, the fruit flavor after storage was better, and the fruit bag with type B was more prominent in improving the value of Shatian pomelo fruit.
