Generally, this work of bagging is carried out one month after flowering, but for different varieties, there may be some differences in time. When bagging, comprehensive insecticidal and sterilization work should be performed on the entire orchard. Wait until these drugs are dried before bagging. Generally speaking, it is best to choose a sunny day at this time. It should not be a rainy day or when there is water on the surface of the fruit. This will cause the fruit to rot.
