Effects of Bag Type on Fruit Quality of Red Massh Grapefruit

[Objectives]The effects of bag types on the appearance and internal quality of red Massh grapefruit were studied.[Methods]Outer-yellow inner-black double-layer pomelo special paper bags,white single-layer paper bags,yellow plastic film bags,and red plastic film bags were used to cover the fruit of red Massh grapefruit.With the fruit free of bagging as a control,the effects of fruit bags with different materials were compared.[Results]The four kinds of fruit bag treatments effectively reduced pests and diseases,and increased the good fruit rate,and the effects of paper bag treatments were better than those of film bags.The outer-yellow inner-black double-layer pomelo special paper bags had good air permeability and were easy to operate.The bagged fruit had a smooth and beautiful surface and showed a unique uniform pink color after removing the bags.The fruit had moderate sour and sweet flavor and good overall benefits.It is worthy of popularization and application.[Conclusions]Fruit bagging has good economic benefits,and it is recommended to use the outer-yellow inner-black double-layer pomelo special paper bags.
