Grape cold storage technology

1. Variety selection Hard and crisp meat varieties are resistant to soft meat type, with large fruit pieces, thick fruit peels, thick wax on the fruit skin, and long brushed fruit species. Therefore, it is advisable to choose Kyoho and global red storage.
Second, the harvesting standard should be selected after clear morning dew and then harvested. If there is moderate rain or watering before harvesting, the harvest should be postponed for another 1 week. The ripening ear with the same size and color of the fruit and ears should be selected to remove the disease and injury. Residual fruit, in order to prevent bacteria from entering the storage, the vinegar should be sprayed once before harvesting.
Note the following grapes cannot be stored:
1. Grapes with insufficient ripeness, sugar content below 14% (15% to 16% of soluble solids), grapes with soft tip or jug.
2. Grapes before picking or in heavy rain.
3. Downy mildew and other heavier grapes.
4. Rotten fruit, green fruit, serious ear size.
5. Grapes that suffer from natural disasters such as frost, blisters, and locust plagues.
3. Disinfect the warehouses with potassium permanganate for 1 week before putting them into the warehouse. Disinfect the surfaces around the ceiling of the warehouse and the ground 1 times. Put 2 kg of sulfur into the 20-ton storage tank for 3 days before storage for fumigation.
IV. Pre-cold harvesting When using a plastic turnover basket with a weight of 20 kg of grapes, place it in the shade during the day and store it in the shade to store it in the evening. Afterwards, reduce the temperature to -1°C as soon as possible. Rapid pre-cooling can quickly reduce the respiratory intensity and ethylene release of stored grapes. Kyoho and other grape pre-cooling time is limited to 12 hours, too long prone to dry stem threshing. When the small packaged grape that is stored in the fresh-keeping bag is put into the storage, the bag opening should be opened to disperse the heat and water brought by the field. After pre-cooling, the bag should be sealed and the pre-cooling room is preferred.
V. Stacking and Preservation Pre-chilled grapes shall be sorghum-packed with 3 tons (ie 20 baskets of 150 baskets). Each basket of grapes shall be placed with 10 packages of preservatives. After the barrier is closed, the plastic film is sealed on the cover to make each pod a self-contained body and become a small environment. The fresh air released by the preservative evenly fills the entire space. The space is large, with a buffer regulating effect, so that the grapes are not susceptible to phytotoxicity. Because of being isolated from the outside world, the carbon dioxide and water vapor produced by grape respiration flooded in the space surrounded by the plastic film and did not emit, weakening the aerobic respiration process and achieving a reasonable respiratory intensity. Due to the heat of breathing, the temperature inside the membrane is higher than that outside the membrane. Most of the released water vapor condenses on the inner wall of the plastic membrane and becomes ice, but does not adhere to the surface of the fruit. The grapes are still clean and the fruit powder is not damaged. Intrusion, the relative humidity of the air in the membrane can be well maintained, thereby reducing the loss of grape fruit moisture and prolonging the storage time.
Sixth, storage management
1. After all the grapes in the warehouse have been put into the warehouse, put a little sulfur between the cricket and the pupa. Close the library doors and ignite them after they are ignited. Kill pathogens brought into the human library. Since the warehouse is an automatic temperature controller, the management personnel no longer enter the warehouse, and the temperature of the warehouse is adjusted by the temperature control device, and the temperature is maintained at -2 to 0°C. The temperature in the plastic film and the warehouse temperature may differ by about 1°C.
2. In the middle period of storage, when the temperature and storage temperature are basically qualified, the ventilation and air exchange will be performed once. After the ventilation, the warehouse door will be closed after being fumigated with sulfur.
3. After two months of storage, the grapes are combined for ventilation and the grape is replaced with fresh plastic wrap. Only fresh wraps are used instead of turning the grapes, and then the grapes are covered again. At the same time, the freshness of the grapes can be checked.
This method is simple to use, low cost, and can be used repeatedly, through the practice of preservation in recent years, the longest preservation time of up to 8 months, the preservation rate of 95% or more, in the simple storage of grapes has promotion value.

Organic wolfberry is a kind of wolfberry produced in the production of organic wolfberry in accordance with the organic agricultural standard, without the use of genetically engineered organisms and their products, without any chemical synthetic pesticides, chemical fertilizers, growth regulators and other substances, and a series of sustainable agricultural technologies.
The organic farming system makes the best use of the available resources in the regional agricultural system (plantations) to encourage and promote biological cycles within the farming system, including microorganisms, plants and animals, and to make full use of organic and nutrient elements within the closed system, and to avoid all possible pollution by farming techniques used in the system. Maintaining and improving the long-term fertility of the soil of the garden, and realizing the sustainable and scientific development of the garden.
High quality, organic wolfberry can be said to be the highest standard in the food industry of Chinese wolfberry; no pollution, the organic wolfberry produced by the transformation of traditional roots garden is under 0.02ppm. The certification standards of organic wolfberry mainly include USDA in the United States and certification of organic products in China.
