摘　　要：以22年生温州蜜柑(Citrus reticulata Blanco cv.Unshiu)植株为试材,分别进行了果袋颜色(分别是红、黄、蓝、白色,套袋时期7月1日,摘袋时期9月25日)、摘袋时期(套袋时期7月1日,摘袋时期分别为9月5日、9月20日、10月5日,以不摘袋为对照,黄色牛皮纸袋)和套袋时期(套袋时期分别为7月2日、8月4日、9月9日;摘袋时期在9月27日,黄色牛皮纸袋)试验,研究套袋对温州蜜柑果实品质的影响。结果表明,在3个试验中,套袋处理均能提高果面的光洁度,增进着色,极显著地降低了果实中可滴定酸和维生素C的含量,极显著地提高了固酸比和糖酸比,大多数能极显著地提高可溶性固形物的含量,但对可溶性糖含量影响不太一致。综合来看,以套蓝袋和红袋改善果实内外品质的效果最好,白袋最差;最佳摘袋时期是9月20日;最佳套袋时期是7月2日和8月4日,过晚套袋则效果不显著。22 years old Citrus reticulata Blanco cv.Unshiu plants were used as experimental material.The fruit bagging tests were carried out with different color of bags（with red,yellow,blue,white film bags;Bagged on July 1,bags removed on Sept 25）,different removal dates of bag（on Sept 5,Sept 20 and October 5 with bag non-removal as the check;Bagging on July 1;All bags made from yellow craft papers） and different bagging dates（on July 2,Aug 4 and Sept 9;Bag removed on Sept 27;All bags made from yellow craft papers） to study the effects of bagging on fruit qualities.The results showed all the fruit bagging treatments could improve fruit surface,enhance coloration,reduce very significantly Vc content and titratable acid content,increase very significantly solid-acid ratio,increase significantly or very significantly soluble solid contents in most of the treatments,and didn＇t show an inconsistent effects on fruit qualities among the treatments.By comprehensive analysis on fruit qualities,the blue and red bags were the best and the white ones were the worst.The best bag removing date was Sept 20 and the best bagging dates were July 2 and Aug 4,bagging too late was bad.
