Recently, the northern cherries have matured and marketed, and the cherry fruit harvest period is in the high temperature season, the fruit is easy to lose water and shrink, lose stems, browning and rot during post-harvest storage, the quality is very easy to deteriorate, and the market supply period is very short.
Choose the right breed
The early-maturing cherry varieties ripen from early May to mid-June, with short fruit development period, thin peel, poor flesh density, and are not resistant to storage, so they can only be cold treated for short-term storage. Late-maturing varieties ripen in late June, with dense flesh and strong adaptability to low temperatures. Therefore, the varieties that mature from mid to late June to early July should be selected for storage and preservation.
Harvest at the right time
The harvest should be carried out in the morning or evening after the dew has dried on a sunny day, when the temperature is low. The fruit should be harvested manually when it is ripe at eight or nine minutes, and it should be with a fruit stalk. During the harvesting and handling process, it should be handled with care, and the fruit should not be damaged. After harvesting, primary selection is carried out to remove cracked fruits, diseased and rotten fruits, deformed (conjoined) fruits, punctured fruits and stiff fruits. After selection, it is packed in a lattice wooden crate or plastic turnover box, and lined with a mat to prevent crushing during transportation.
Scientific storage
After harvesting, cherries should be put into the cold storage immediately to pre-cool, as far as possible to shorten the time from post-harvest to cold storage. If it is packaged and transported for storage immediately after harvesting without pre-cooling, the temperature of the storage environment will increase and the humidity will increase due to the heat in the field, and the respiration of cherries will continue to be strong, resulting in heat accumulation and rotten fruits.
According to the different varieties, storage time and equipment conditions, storage is usually divided into simple packaging and modified atmosphere packaging, and the temperature is 1 °C-4 °C. Simple packaging and storage is suitable for short-term storage, the method is simple, the cost is low, but attention should be paid to the selection of non-toxic and good air permeability of film packaging, the oxygen and carbon dioxide concentration is controlled within a certain range, so as to play its role of spontaneous atmosphere modification in delaying aging, inhibiting the growth of germs and reducing water loss. Due to the thin and juicy skin of the fruit and the poor ability to resist mechanical damage, the film bag should not be too large, and it is appropriate to hold 1-2 kg of fruit per bag. If it is necessary to extend the storage time, the modified atmosphere storage method can be used, and the appropriate indicators are: oxygen 3%~5%, carbon dioxide 5%~10%, relative humidity 90%~95%. The storage period can be significantly prolonged by the modified atmosphere method, the decay rate and browning degree of the fruit are reduced, and the firmness, color and flavor are well maintained, but the relative cost is high.
