What are the effects of bagging apples on fruit quality and yield compared with not bagging?

1. Impact on fruit quality
Appearance quality
Bagging: The use of Apple Protection Bag makes the apple surface smooth and beautiful, bright in color, without fruit rust, and excellent in appearance. Because the fruit is isolated from the outside world, it avoids wind, sun, rain, pesticides, and dust pollution, making the fruit surface more delicate and evenly colored, improving the commercial quality of the fruit.
No bagging: The fruit surface of unbagged apples is easily affected by the external environment. For example, wind and sun will cause the fruit surface to be rough, the pores to be coarse, and even spots and fruit rust may occur. In addition, pesticide residues may also affect the appearance of the fruit surface.
Taste and flavor
Bagging: Although the use of Apple Protection Bag can improve the appearance quality of the fruit, it may also have a certain impact on the taste and flavor. Because the bagged apples grow in relatively closed and light-proof conditions, the organic acids, soluble solids, sugar-acid ratio, etc. in the fruit may decrease, resulting in a lighter flavor and a worse taste than unbagged apples.
No bagging: Apples without bags absorb and accumulate more trace elements in the fruit due to natural light and rain, thick peel, good toughness, good fruit hardness, strong disease resistance and stress resistance, higher sugar content than bagged apples, and more simple flavor.
Incidence of pests and diseases
Bagging: Bagging can effectively reduce the occurrence of pests and diseases, protect fruits from ring rot, sooty mold, leaf spot disease, pox spot disease, peach borer, apple borer and other pests and diseases.
No bagging: Apples without bags have a relatively high incidence of pests and diseases due to direct exposure to the natural environment. This may cause damage to the fruit and affect the quality and yield of the fruit.
2. Impact of yield
Bagging
Increased cost: The cost of Apple Protection Bag cultivation is relatively high, including the cost of paper bags, the labor cost of bagging and bagging, etc. These costs increase the burden on fruit farmers and may also affect the economic benefits of the orchard.
Yield and commodity rate: Bagging can increase the commodity rate of fruit, making the fruit more in line with market demand. However, due to improper operation during the bagging process or problems with the fruit's own growth, some fruits may be damaged or fall, thus affecting the yield.
No bagging
Reducing costs: No bagging cultivation can greatly reduce production costs, reduce expenses such as paper bags and labor costs. This enables the orchard to obtain higher economic benefits under the same management level.
Increasing yield: Since the fruit grows under natural conditions, the yield of no bagging cultivation is usually higher. Under the same water, fertilizer and management level, the yield of no bagging cultivation can be significantly improved, and the yield per acre can be increased by about 20%.
III. Comprehensive benefit analysis
Market demand: As consumers pay more attention to food safety and quality, bagged apples are favored for their beautiful appearance and low pesticide residues. However, some consumers prefer unbaked apples with a simple taste and rich flavor.
Development trend: Although Apple Protection Bag technology is of great significance in improving fruit quality and commerciality, with the shortage of agricultural labor and rising labor wage costs, no bagging cultivation has gradually attracted attention. Non-bagging cultivation can not only reduce costs and increase yields, but also has higher requirements for pesticide quality and plant protection technology, which is conducive to promoting standardization and large-scale management of orchards.
