1. The maturity of fresh jujube fruit is closely related to the waxy film of the skin and thickening of the cuticle membrane, which is closely related to the weakening of the air permeability. This leads to the increase of respiratory quotient and the formation of anaerobic respiration, which causes the ethanol fermentation to mature and age the jujube fruit. Therefore, fresh dates that are generally required for storage should be harvested during the reddish period. Second, preservation of fruit stems when harvesting is an important measure to improve the storage stability of fresh dates. According to the preservation test of winter jujube, it was proved that the winter jujube without fruit stalks was wilted quickly, the stalks were easily rotted, and the storability was greatly reduced. Therefore, it is necessary to store fresh dates, emphasizing picking with stalks.
