What is the function of fruit bagging?
Comprehensively analyzing the role of fruit bagging in the field of green plants and flowers, the following is a detailed explanation by the editor.
What is the function of fruit bagging?
Reduces pesticide residues, as after bagging, the fruit is isolated from the outside, and the fruit is no longer contaminated during pesticide and fertilizer application. Improves fruit quality, as after bagging, the fruit's growth is not affected by the external environment, resulting in superior quality. Reduces the risk of pests, as bagged fruit can avoid the invasion of most pests. After bagging, natural weather conditions such as rainy and sunny days cannot affect the fruit.
Fruit bagging is a very common practice with many advantages. It ultimately improves the quality of the fruit, increases yield, and increases farmers' income. Specifically, the main functions of fruit bagging are as follows.
Advantages and Functions of Fruit Bagging
1. Reduces pesticide residues, as after bagging, the fruit is isolated from the outside and not contaminated during pesticide and fertilizer application.
2. Improves fruit quality, as after bagging, the fruit's growth is not affected by the external environment, resulting in superior quality.
3. Reduces the risk of pests, as bagged fruit can avoid the invasion of most pests.
4. Reduces the impact of natural disasters, as after bagging, natural weather conditions such as rainy days and strong sunlight cannot affect the fruit.
Taking grape bagging as an example, its advantages include:
① Improves fruit surface smoothness
② Reduces fruit diseases and pests
③ Increases fruit coloring
④ Reduces the number of pesticide applications
⑤ Lowers pesticide residues in the fruit
⑥ Reduces bird damage
How to Bag Fruit
1. Bagging should be done on sunny days.
2. Before bagging, remove any excess leaves from the fruit stem or cluster base.
3. Before bagging, spray the fruit comprehensively with pest and disease control agents allowed for use in non-harmful food products, and after the pesticide dries, proceed with bagging. Finish bagging the fruit that has been sprayed on the same day.
4. Bagging bananas 15-20 days after flower bud removal. Bagging longan and lychee after fruit thinning. Bagging pears and peaches about 30 days after flowering. Bagging mangoes 45-60 days before harvest. Bagging loquat about 30 days after flowering and fruit setting. Bagging pomelos and oranges from mid-May to early June.
Fertilizer and Water Management After Fruit Bagging
Orchards with bagged fruit need to strengthen fertilizer and water management and leaf protection to maintain strong tree growth and meet the fruit's growth needs.
Due to the decrease in calcium content in bagged fruit, which is prone to bitter pit disease and others, spray 300-500 times of amino acid calcium or amino calcium or amino acid complex micro-fertilizer once a month from July to September.
Apply 500 10^-6 rare earth once each in late June, 40 days before harvest, and 20 days before harvest, or spray photosynthetic micro-fertilizers such as "Nongjia Wang" in June, July, and one month before harvest to increase the soluble solid content in bagged fruit.
Water thoroughly before fruit expansion and before removing the bags to meet the water needs of bagged fruit and prevent the target.
The above introduction on the role of fruit bagging is for everyone to learn and understand!
