1. Yali pear: Yali pear is a traditional fine variety in North China. It can be used for storage, cellar storage, ventilation storage, and cold storage. Cold storage requires that the relative humidity be kept above 90%, and the cooling should be carried out in sections. That is, after the temperature drops to 10°C, the temperature is stable for 3 days, the temperature is lowered by 1°C every 3 days, and dropped to 1°C every 2 days after falling to 4°C. Drop to 0.5. 2. Avocado: Although the peel of avocado is thick, but the meat is fine, it is a famous local variety. Can be stored in small bags and large storage, can also be controlled atmosphere storage. The best storage temperature is 0-10°C, relative humidity is 95%, oxygen concentration is 3%-4%, carbon dioxide concentration is 2%. Pear is susceptible to diseases, and must be sprayed with low-toxic and highly effective bactericidal drugs before harvest. 3, snow pear: snow pears good storage, can be stored in the trench, storage pits and storage bags small package storage. The storage temperature should not be lower than 0°C, the optimal storage temperature is 0-1°C, and the relative humidity requirement is 90%-95%. 4. Qiubai Pear: The optimum storage temperature is -1 to 0°C, and it can be stored in a ventilated storehouse. However, the fruit temperature must be pre-cooled to 10°C before storage, and then stored in storage. For cold storage or controlled atmosphere storage, the storage temperature is preferably 0°C, and the concentrations of carbon dioxide and oxygen are both 3%-5%. 5, pear: the best storage temperature is 1-5 °C, not lower than 0 °C, relative humidity 90%, can be cold storage, ventilation storage. 6, long pear: long pears good storage, suitable for trenches, cellar pits, ventilation storage. Stored in the field before the storage temperature is below 10°C, and cool down after storage. The optimum storage temperature is 0-1°C and the relative humidity is 90%-95%. 7, Pakistani pear: Pakistani pear is not resistant to storage at room temperature, generally 10 days or so quickly cooked, aging, corruption, timely recovery after timely refrigerated storage can also be controlled atmosphere. The optimal refrigerating temperature is 0°C, the oxygen content is 2%-4%, the carbon dioxide content is 3%-4%, and the relative humidity is 90%-95%. The air-conditioned storage of Pear, after leaving the library, should be placed at a temperature of 2O°C for 3-4 days until the ripening is complete. 8. Mianfeng Pear: Mianfeng Pear can be stored in Tujiadong, ventilated storage and cold storage, but it is not suitable for air-conditioned storage. Suitable storage temperature is 0-1 °C, can not be lower than 0 °C, relative humidity requires 90%-95%. In areas where the disease is serious, preservatives must be sprayed before harvest. 9. Nanguo Pear: Nanguo Pear is a fruit with obvious respiration change. After nine mature harvests, it is first cooled at 5-7°C for 2-3 days. Then put it in a cold storage at 0°C and store it for 3-4 months. Atmosphere storage first storage at 15 °C temperature for 3-5 days, then transferred to 0 °C air-conditioned library, controlled oxygen content of 2% -3%, carbon dioxide content of 3% -4%, can be stored for 5 months. It can also be stored in PE plastic bags and stored in a 0.04 mm thick PE bag before the flesh is softened. The temperature of the container can be reduced from 15°C to 0°C within 10 days, and the oxygen concentration in the control bag is 5%-10. %, carbon dioxide concentration 3%-5%.
