With the development of the fruit market and people's concepts, high-tech has gained more and more attention in the production. Fruit bagging has become the main direction of development in the commercial production of the apple industry. Showed a variety of advantages: 1, Apple bagging can significantly increase the fruit surface finish, improve the appearance of the fruit quality of the product, and the high price and high economic efficiency. 2, bagging to promote a fruit increase. On the one hand, bagging apples strictly controls the retention and retention of fruit, ensuring the full supply and effective use of nutrients. 3, bagging reduce pest damage. After bagging, the fruits are isolated from the outside world, and pathogens and pests cannot be invaded by humans. It can effectively prevent and treat diseases such as ringworm disease, anthrax, and peach borer. 4, bagging can prevent hail, to avoid natural disasters on mechanical damage to fruit. Hails occur mostly in the young fruit period. At this time, the fruit is still small and hangs in the fruit bag. The ice clams fall onto the bag that the drum has risen, slowing its mechanical momentum and protecting the fruit from harm. 5. Reduce pesticide pollution and residue. After bagging the fruit does not directly contact the pesticide, reducing the pollution of the pesticide. Apple bagging also has some drawbacks, mainly in the following aspects: 1, reduce the fruit sugar, resulting in light flavor. Generally, the sugar content of bagged fruits is lower than that of unbagged fruits. 2, increase the possibility of sunburn. Increase the possibility of calcium deficiency physiological disease. 3, bagging weakened the transpiration of the fruit surface, thereby reducing the absorption of calcium in young fruit. 4. Bagging takes time and labor, increasing production costs. However, judging from the current situation, Apple's bagging outweighs the disadvantages, or should be vigorously promoted.
