1. The air-controlled storage uses a 0.025 mm thick polyethylene film bag to seal and store the plum fruit. At 0°C to 1°C, the general gas composition is 3% oxygen and 5% to 7% carbon dioxide. Liguo can be stored for 70 days. Can significantly inhibit fruit rot, soft and soluble solids reduced. According to reports, under the condition of 0°C, relative humidity of 90%-95%, oxygen of 3%, and carbon dioxide of 3%, Liguo has good storage effect. 2. The small package storage will be timely picked Li Guo after selection into the polyethylene film pouch, 1 kg to 1.5 kg per bag, sealed at -1 °C conditions, can be stored for 2 to 3 months. 3. The ice storage and refrigeration method is a traditional natural cryogenic storage method in China. Before the chill, the North collected natural ice or sprinkled water to make ice. The ice cubes are 0.3 to 0.4 meters thick, 1 meter long and wide, and they are stored in underground pits. When the plums mature in summer, they are used for storage and cooling. Li Guo, who had better resistance to Tibet, was selected for timely recovery without injury and was shipped to the ice cell after precooling. Store 0.5m thick ice cubes on the bottom of the cellar and on the four sides. Stack the fruit boxes on top of it. The layer of fruit boxes is covered with ice cubes. Fill the gaps with crushed ice. After stacking, heat insulation material such as rice straw is covered at the top to maintain a relatively stable temperature. The method can store fresh plums stored in late August until the beginning of winter. If transferred into a common pit for continued storage, it can be stored until New Year's Day. The cellar door should be closed during storage in the ice cell, and the cellar temperature should be controlled as low as -0.5 to 1°C.
