1 pre-mining treatment 1.1 3 to 5 days before mining using “anti-drop No. 1” 500 times spraying spikes, the time is sunny 9 am to 11 am as well. In the event of rainfall within 6 hours after spraying, it can be replenished and sprayed once. Before spraying, spray can also be sprayed on the No.1 Pre-harvest grape which was developed by Shanxi Institute of Agricultural Products Storage and Preservation. 1.2 timely mining, thickening cream grape no obvious after-ripening and after-ripening process, therefore, for storage of grapes should be fully mature after appropriate mining, take full advantage of autumn and cool, large temperature difference between day and night to improve the maturity. Longan grapes in full maturity, with 1 to 2 times the light cream, fruit cream significantly thickening, sugar reached the highest, storability
