In recent years, grape production in Changxingdian Town of Beizhen City has developed rapidly and production has increased rapidly. Storage technology of large-grain fresh table grapes has become an important issue facing local grape production. Since 1992, many people have been renting cold storages in Shenyang and some cities in Jilin Province to store grapes such as Kyoho. By 1997, 15,000 tons of grapes had been stored off-site, increasing the economic benefits of 30 million yuan. In order to improve the benefits of grape storage in different places, the author has studied and summarized the collection, packaging, transportation and storage of different varieties of grapes in recent years. 1. Select high-quality fruit, grape yield is best controlled at an average of 1500 kilograms per mu, and fruit soluble solids content should be above 17%. The fruit is best matured naturally, do not spray ethephon and Other ripening agents, and stop watering for about one week before harvesting. 2. Kyoho grapes are harvested in mid-to-late September, and late-maturing varieties such as Red Globe, Okuyama Ruby, and Italy are harvested in mid-October. The cold weather was harvested and collected into a box lined with a polyethylene film of 0.05 mm, and then the bag was precooled overnight at a constant temperature of 1-2°C. The grape fresh-keeping agent medicine bag is used to tie two eyes with a pin, put 4 bags per kilogram, put on the ear, and tie the film bag. 3, grapes stored in different places, the packaging should be small, only 1 layer of fruit inside the box, each box of 5-7 kg is appropriate to prevent the fruit in the transport due to squeeze or fruit cracking, reduce the loss rate of off-site storage. When loading and unloading trucks should be handled gently, 20-30 km after starting, the speed should be slow and stable. 4. Strictly control the temperature during the storage period of the grape into the cellar, store the temperature at minus 0.5 to minus 1 °C, and control the temperature at minus 1 °C at the beginning of March. In the cold room, it is appropriate to store 175 kg of grapes per cubic meter of space. 5, Red Fuji, Kyoho, Red Earth, Okuyama Ruby, Italy 5 grape varieties, with Red Earth, Okuyama ruby, Italy's most resistant storage and transportation, storage 185 days, the total loss rate of 1.3% -2.0%, full fruit, Fruit stems are fresh green, basically without falling grains, good quality and good taste. They are excellent grape varieties that can be stored and transported in Jinzhou area and can be stored for 7 months. Kyoho is a species that is relatively resistant to storage and transportation, with a total loss of 3.4% for 150 days. Red Fuji was not resistant to storage and transportation for 3 months, and the total loss was 7.5%. It was severe during the storage and transportation process. China Agricultural Network Editor
