In the process of using fruit protection bags, how to manage and maintain these bags to ensure their effectiveness?

In agricultural production, the use of fruit protection bags has become a common measure to protect fruits from pest infestations and external environmental impacts. However, for these protective bags to truly play their role, they must be managed and maintained scientifically.

1. Purchase and preparation
Choose high-quality materials: Choose protective bags made of high-quality materials that are wear-resistant, anti-aging, waterproof and breathable. Make sure the bag is non-toxic and harmless and will not cause contamination to the fruit.
Specification matching: Choose a protective bag of appropriate specifications according to the variety and size of the fruits being grown. A bag that is too big or too small will affect its protective effect.
Quantity preparation: Calculate and prepare enough protective bags in advance based on the area of the orchard and fruit yield.

2. Pre-use treatment
Cleaning and disinfection: Before use, clean and disinfect the protective bag to remove possible bacteria, viruses and other harmful organisms.
Check the quality: Check the protective bags for damage, cracks and other quality problems to ensure that each bag is intact.
Pretreatment: For protective bags that require pretreatment (such as applying insect repellent), follow the instructions to ensure that the agent is evenly applied and not excessive.

3. Usage process management
Timely bagging: The timing of bagging is very important. Bagging is usually performed when the fruit grows to a certain stage, such as the young fruit stage. Bagging too early or too late may affect fruit quality and yield.
Correct bagging: When bagging, make sure the fruit is completely wrapped in the bag and the mouth of the bag is tightly attached to the fruit stem to prevent pests from invading through the gaps. At the same time, avoid bags that are too tight or too loose to avoid affecting the growth of the fruit.
Regular inspection: Regularly check the integrity of the protective bag, and replace or repair any damaged or fallen bags in time.
Pest and disease control: Although protective bags can block most pests, they still need to be combined with other pest and disease control measures, such as spraying pesticides.
Weather response: During the bagging process, pay close attention to weather changes. If severe weather such as strong winds or heavy rain is expected, the bagging work should be suspended to prevent the bags from being blown off by the wind or damaged by rainwater.

4. Post-harvest processing
Timely bag removal: Remove the protective bags in time before the fruit matures to facilitate the coloration and quality improvement of the fruit.
Cleaning and sorting: After harvesting, clean and sort the used protective bags to remove dirt, residue and other impurities.
Classified storage: Classify and store the cleaned protective bags according to specifications, materials, etc. to facilitate selection and management for next use.
Inspect and repair: For damaged or aging protective bags, repair or replace them to ensure that they can provide good protection the next time they are used.

5. Continuous improvement
Recording and analysis: Record and analyze problems and phenomena that occur during the entire use process, find out the causes and propose improvement measures.
Training and education: Regularly provide training and education to fruit farmers on the use and management of fruit protective bags to improve their understanding and usage skills of protective bags.
Technology update: Pay attention to the development of new agricultural technologies, and timely introduce and update more advanced fruit protection bag products and technologies.
