Last Updated: 2024/11/06, At present, the methods of storing peaches include ice cellar storage, improved ventilation storage, cold storage, controlled atmosphere storage and so on. The suitable temperature for peach storage is 0: 3 ℃. The temperature of large-scale cold storage is uneven, the precision of temperature control is poor, the fresh-keeping effect is poor, and it is not easy to operate and manage. Tzfgz series hanging-up automatic cold storage is a new type of storage and fresh-keeping cold storage developed and popularized by Shandong Fruit Tree Research Institute. The temperature control precision is 0.1℃, the cooling speed is fast, the storage temperature is uniform, and low temperature and high temperature can be used as needed.

Tzfgz series hanging-up automatic cold storage is a new type of storage and fresh-keeping cold storage developed and popularized by Shandong Fruit Tree Research Institute. The temperature control precision is 0.1℃, the cooling rate is fast, the storage temperature is uniform, and the low temperature and high temperature can be adjusted freely according to the needs. The storage of peach fruit can effectively reduce and avoid the occurrence of cold injury.

Peach fruits for storage should be pre-cooled immediately after picking, so as to shorten the time from postharvest to cold storage.

The water content of peach fruit is 80%-90%, and it is easy to lose water and shrink. When the weight loss reaches 4%-5%, the skin shrinkage can be seen with the naked eye. Can be stored with 0.03mm 0.05mm non-toxic PVC fresh-keeping bag, not wrinkled, maintain a certain degree of freshness. Check regularly after storage. Peach fruits stored for a short time should be observed every day, and medium-and long-term stored fruits should be inspected every 3 to 5 days.

During storage, peach fruits are prone to brown rot, soft rot and green and green mildew. In order to prevent the occurrence of diseases, a series of preservative agents of sec-butylamine can be used to kill penicillium and green mold, such as washing fruit with clotrimazole 15 times solution. The fruit was soaked with a mixture of 100mg / kg benzoate and 450mg / kg dichloronitroaniline (dgna).
