Before the harvesting method is exported or stored, the fruit is pre-cooled to 4-5Â°C. To prevent mechanical damage, the packaging containers should not be too large, each containing 6-10 kg, before the packaging, Li Guo should be pre-cooled as soon as possible, pre-cooling method to use 0.5-1 Â°C cold water cooling effect is better.
1, cold storage. Storage temperature is 0-1 Â°C, humidity is about 90%, plums stored at -1 Â°C 45-60 days will cause browning caused by low temperature, should pay attention to avoid this temperature. Prior to plums entering the store, formaldehyde or sec-butylamine fumigants were used for disinfection. 2. The plastic bags are stored at low temperature and controlled atmosphere. A 0.025 mm thick polyethylene film was used for fruit packing. Each bag of 5 kg, after the bag is fastened, stored at 0 - 1 Â°C. It can be stored for 10 weeks under the condition of oxygen concentration of 1% -3% and carbon dioxide concentration of 5%.
