Orange bagging is an advanced method to produce high-grade fine oranges. The quality of oranges produced by bagging is better, and the price is more than 1 yuan per kilogram higher than that of unbagged fruits. So how do you bag oranges? Let's take a look.

1. Spray before bagging

Before bagging oranges, you should first spray liquid medicine to avoid germs on the fruit. If you continue to harm the fruit after bagging, the bag will lose its original meaning. Fungicides can be sprayed with new high-fat membrane liquid, which can not only protect the fruits and leaves of the plant from bacterial infection, but also play the role of liquid membrane bagging. Spraying will not affect the normal growth of the fruit, but also can improve its coloring degree, spraying 2-3 times in a row, after the last spraying, 2-3 days after bagging, the fruit surface should be kept clean, there should not be liquid or dew, so as not to cause the fruit to rot.

2. Bagging time

In addition, the time of bagging day should also be chosen, which is suitable for around 9: 00 a.m. or 4: 00 p.m., and try to avoid the periods when the dew is not dry in the morning, the high temperature and strong light at noon and the return of tide in the evening.

3. Bagging method

Choosing a double-layer or single-layer paper bag as a bag requires light and black color, moderate light transmittance, good air permeability, strong expansion and low water absorption, but in areas with low temperature in winter, it is recommended to use double-layer bags. When bagging, we should grasp the principle of first going up and then down, first inside and then outside, first covering the fruits of the upper and inner layers of the crown, and then the fruits of the lower and outer layers. Open the mouth of the bag so that the mouth of the bag is facing down and put the fruit into it. The fruit should be suspended in the center of the bag and should not touch the side of the bag. Tie up the mouth of the bag.

4. Management after bagging

To do a good job in the management of the garden after bagging, first of all, spray chemicals in the whole garden 10-15 days after bagging, check the bagging situation, and replace it in time once it is found that the bagging is damaged.
