1. Improve the appearance quality of citrus fruits: The fruits in the sunny part around the canopy of citrus trees are easy to form sunburn on the peel and dry flesh when exposed to high temperature due to no leaf shielding, thus producing sunburn fruits with low edible value. The traditional method is to paint white or sticker, but the effect is not ideal. Bagging can effectively prevent the production of sunburn fruit. According to statistics, it can reduce the rate of cell embrittlement and lignification of Guanxi honey pomelo juice by about 75%. Bagging during the young fruit stage of citrus can effectively prevent scratches and reduce the number of reticulate fruits. Gannan navel orange has about 15% sunburn fruits and reticulate fruits, and about 10% spot fruits, diseased and insect fruits every year, which greatly reduces the rate of commercial fruits. Through bagging, the high quality commercial fruit rate of citrus can be effectively improved. The fruit bagging can also effectively improve the thickness and evenness of the orange peel oil cell, so that the whole fruit surface is smooth and beautiful, and the color is consistent.

After bagging, citrus fruits are isolated from the outside world, which can reduce the chance of infection with bacteria and reduce the rate of diseased fruits. Scale insects and rust lice often damage citrus fruits, causing black peel and scar, affecting the commodity of fruits. Proper spraying of pesticides before bagging can prevent the insect source on the tree from invading the inside of the fruit bag. Make the fruit grow in a pest free space all the time, and finally get the citrus fruit without pest damage.

3. Reduce pesticide residues and improve efficiency: bagging orchard can reduce the application frequency and amount of pesticides when the damage of pests and diseases to trees is not serious, so as to save costs and reduce the pollution of pesticides to the environment. The pesticide residue of bagged fruit was lower than that of common fruit. The bagging of citrus can reduce the ratio of diseased and damaged fruits and improve the quality of citrus fruits so as to improve their commercial value. Its comprehensive added value is far greater than the cost of bagging.
