Why Are More and More People Using Fruit Growing Bags For Apples?

Whenever you walk into the apple orchard, you will always see one apple wrapped in a fruit growing bag. What are the benefits of this fruit growing bag? Why is it being used by more and more people?

1.Promote the coloring of apple fruit surface

Through bagging, apple fruit grows under shading conditions for a long time, which inhibits the synthesis of chlorophyll, thus making the ground color on the peel surface lighter, which is conducive to the full display of anthocyanin, and making the fruit show bright red color based on the little green ground color.

2. Preventing and removing fruit rust

The environment of all parts of the fruit surface after bagging apples is relatively uniform and consistent, which greatly reduces the direct stimulation of external adverse environmental conditions such as wind, rain, pesticides, harmful light and so on, thus reducing the self-protection function of fruits, the peel develops stably and gently, and the epidermal cells are closely arranged. Shading by bagging also makes epidermal cells secrete less wax, reduce lignin synthesis, inhibit the occurrence and activity of cork cambium, and make lenticels occur less and less. Bagging apple fruit can not only prevent fruit rust and reduce fruit point, but also prevent coal stains, drug spots, branches and leaves abrasion spots, etc., which pollute the fruit surface, and make the fruit surface bright and beautiful.

3. Reduce pesticide residues

After bagging apple fruit, the fruit growing bag blocks the contact between the fruit surface and the outside world, and the chance of bacteria invasion is greatly reduced. Practice shows that bagging has a good control effect on fruit borers, such as fruit borers, leaf rollers and mites that lay eggs on fruit surfaces and leaves, and various fruit diseases, such as ring rot, anthracnose and other rotten fruit diseases. The number of pesticide spraying can be reduced by 2 ~ 4 times in the whole year. Because the application times of apples were reduced after bagging, the pesticide residue was reduced. The pesticide residue of bagged fruits was only 0.045 mg/kg, while that of non-bagged fruits was 0.24 mg/kg. Apple bagging has become one of the indispensable measures to develop green food at present.

It is best to use double fruit growing bags for apples. Because the bagged apples are removed two times, the inner bag can play a buffering role after the outer bag is removed, so that the apples can gradually adapt to the external light conditions, protect the apples from burns and safely enter the coloring period. Apples are always in a dark environment. If they are exposed to sunlight at once, the delicate skin of apples will be easily burned under the irradiation of ultraviolet rays, and the red inner bag is more conducive to coloring apples. The coloring quality and chromaticity are better than those of single-layer bags, which is conducive to improving the output value. Therefore, bagging has so many benefits, so use it quickly!
