First, the plastic bag storage method To the tomatoes into a 45-60 cm long, 30 cm wide plastic bag made of 0.04 mm thick polyethylene film, in the lower 1/3 of the bag mouth with fine pins 3 -4 pairs of symmetrical holes, seal the mouth, store in a cool, dry room. Second, the chemical storage method Sulfur dioxide and lime water immersion method: Sulfur dioxide is introduced into the clarified saturated lime water solution to make the pH value of 4.5-4.6. Soak the tomatoes with full red color. The operating procedure is the same as the above method. Using this method to store tomatoes for 4 months, the good fruit rate is 95%, and the cost is low and the effect is good. Third, the modified atmosphere storage method can extend the storage period, and store the tomatoes produced during the peak season in July in the off-season in August. Autumn tomatoes can also be freshly stored until the Spring Festival. 1. Storage method: Atmosphere storage in the ventilation warehouse. Pick fresh and not fully ripe tomatoes into the storage baskets, each containing about 25 kg. First lay a piece of plastic film slightly larger than the bottom on the floor, and place 20 kilograms of lime on the film. Place the mattress and put it on top. The dragonfly is rectangular, six baskets long, four baskets high, two baskets wide, and 48 baskets per basket. After the weights are good, use the prepared storage cover on the rake, wind the edge of the account together with the plastic film on the floor, cover it with soil, and tightly cover it with the soil. Plug it with a stopper. 2. Note: In rural areas, the method of natural adjustment is used, that is, oxygen is used to breathe oxygen from the fruit itself, and the oxygen is gradually consumed to the content range required by the storage, and then it is controlled within this range. Check once every half month to pick out the ripe and rotten fruit, and also play a role in ventilation. Gas analyzer can also be used to determine the gas composition in the account. If the oxygen content is less than 2%, it can be supplied by a blower to supplement oxygen. If the carbon dioxide is higher than 6%, some hydrated lime should be added.
