How to store grapes can not fall

Low air humidity, dehydration of fruit, and stem shrinkage are important reasons for the large amount of threshing of grapes during storage. Therefore, to maintain the storage room with a high relative humidity during storage. At 0°C-1°C, the relative humidity should be controlled at about 90%. It is usually lined with several layers of paper or added with a film bag to maintain moisture. At the same time, it is also necessary to prevent the humidity from being too high, causing the grapes to rot. If the grapes were sprayed with 50ppm-100ppm of naphthaleneacetic acid and 1ppm of gibberellin 3 days before harvesting, there was also the effect of keeping the fruit stems fresh and the fruit pieces not falling off.
