[Effects of bagging on the fruit quality in Litchi chinensis fruit and pesticide residues in it].
Different color bags were used to cover Litchi chinensis fruit to study the effects of bagging on its quality and pesticide residues. The results showed that bagging significantly improved the fruit color. Using bagging techniques, the I and II class fruit was accounted for 57.87% to 81.57%, 30% higher than that of control, and the weight per fruit increased significantly. Among the color bags used, white bag was the best. When the end of the bag was opened, it was benefit for decease control, but not good for pest control. When the end of the bag was closed, it was good for pest control, but bad for decease control. Bagging had no effects on the taste of Litchi chinensis fruit, but might increase the residues of fenpropathrin and trichlorphon. More study should to be carried out to select the suitable pesticides accompanied with bagging techniques.
