Colorful and colorful. Bagging can significantly improve the coloration of the fruit, up to the full red fruit, the fruit surface is smooth and beautiful, no rust, good appearance, according to the experimental fruit surface coloration greater than 75% proportion accounted for 86.7%.
Prevent pests and diseases. After bagging, the fruit is isolated from the outside world, and germs and pests cannot be invaded by humans, which can effectively control rotifera disease. Coal pollution disease. The harm of spotted defoliation disease, pox spot, peach small heartworm, pear chunkun and other pests.
Mitigate hail hazards. Hail mostly occurs at the young fruit stage. At this time, the fruit is still small hanging in the bag, and the hail falls on the bulging bag, slowing down its mechanical impulse and saving the fruit from it. According to our investigation, when the bagging fruit is harmed Xiaoice by hailstone, the bagging fruit is not harmed; When the unbagged fruit is seriously harmed by hail, the bagging fruit is less damaged.
Good for the production of green food. After bagging, the fruit does not come into direct contact with pesticides, and the number of sprays can be reduced. Unbagged orchards need to apply pesticides 8 times a year, bagged orchards 4---5 times. It can effectively reduce the amount of pesticide residues, which is conducive to the production of pollution-free green food and lays the foundation for export foreign exchange earnings.
High economic efficiency. In recent years, the apple market has shifted from a seller's market to a buyer's market, and merchants have increasingly strict requirements for fruit quality, and some orchards have high yields, but the commodity rate is low and the benefits are not good. Bagging can increase the commodity rate of orchards to about 90%, while the fruit surface is tender and smooth, bright coloring, excellent appearance, low pesticide residues, high price, easy to sell, from the market sales point of view, bagging fruit than unbagged fruit price is about double, and the supply is in short supply.
