【Abstract】 Fruit bagging in the course of pear’s growing,one of the main ways by which non-polluted, high-quality pear is produced,not only can avoid the fruit damaged or infected by pests,diseases and birds. etc, but can reduce the remains of pesticide in the fruit and uniformly put color on the surface of fruit as well,which therefore improve the fruit quality.Compared to the fruit without being bagged,fruit-bagged has smooth and clean surface which doesn’t have stained spots, avoid scorch caused by sunlight and has hardly been contaminated, while the fruit weight reduces a bit, the fruit tastes slightly tasteless. Among the four kinds of bags, ambilayer bags play more effectively than monolayer ones.更多还原
