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 For symmetrical holes, seal the bag and store it in a cool, dry room. Second, the chemical storage method 1, sulfur dioxide lime water immersion method: the sulfur dioxide into the clarified saturated lime water solution, made of pH value of 4.5-4.6, the red tomatoes soaked in them, the same operating procedures and the law . 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 is carried out in a 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. Precautions: The method of natural adjustment in rural areas is to use the fruit itself to breathe oxygen, gradually consume oxygen to the content range needed for storage, and then control it 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.
