It is best to choose a double-layer or single-layer paper bag, which requires light and black inside and outside, moderate light transmittance, good air permeability, strong expansion and weak water absorption, but in areas with low temperature in winter, it is recommended to use double-layer bagging. When bagging, we should grasp the principle of going up and down first, first inside and then outside, first cover the fruit of the upper part and inner layer of the crown, then the fruit of the lower part and outer layer, and open the mouth of the bag first. Make the mouth of the bag face down and put the fruit into it, the fruit should be suspended in the center of the bag, should not touch the bag surface, and finally tie up the mouth of the bag.

4. Management after bagging

10-15 days after bagging, spray chemicals in the whole garden to check the bagging situation. Once bagging is found to be damaged, it should be replaced in time. When using chemicals, it is forbidden to use copper pesticides, so as to avoid flower spots in the fruit and affect the quality of the fruit.
