How To Transport Cherry?

large Cherry It is the earliest mature tree species in deciduous fruit trees, and is known as "the first branch of spring fruit". Its color is colourful, delicious and fragrant, and is known as the fruit treasure. But the cherry fruit is intolerant. Storage and transportation And often due to improper postharvest handling, resulting in fruit decay, loss or loss. commodity value 。 To this end, the harvest, packaging and storage of cherry were carried out. Method The following are for reference.

　　 1 harvest

A large cherry that is transported or stored is suitable for harvesting at medium well. The fruit stalks should be preserved and gently placed. The bottom and sides of the fruit basket should be covered with paper so as not to damage the fruit. Harvest should be carried out in the morning or evening after dry dew.

　 2 packaging

The use of exquisite packaging can improve the value of cherry products. Small packages (retail packaging) are generally made of paper or non-toxic hard molded boxes or disks. For example, in China, Shandong uses 0.25kg transparent plastic boxes and 1.0kg, 2.5kg portable transparent cartons. In the United States, a small package is made of transparent film bags, folding boxes, fruit platters and so on. Folding boxes or fruit plates are equipped with membrane windows, which can hold 1 ~ 2kg fruits. If transported or stored in a perforated carton or fiberboard box,

　 3 storage

3.1 simple storage

Under protected cultivation, cherry can mature in early April. At this time the temperature is low, if the selected fruit is packed into a box, stored in a cool and ventilated empty house, it can be stored for about 7 days. Cherry grown in open field is mature in early June. A rectangular groove can be excavated in front of the shady ventilation area. The size of the ditch is determined according to the volume and storage capacity of the box; the selected fruits are packed into small boxes and placed in the trench; in order to maintain certain temperature and humidity, covering the grass curtain or straw, the method can be stored for about 7 days.

　 3.2 low temperature storage

Using mechanical refrigeration, the temperature can be maintained at -1 ~ 1 C, and the relative humidity is 85% ~ 90%, which can be stored for about 30 days. Pre cold storage can improve the storage effect. Generally, the air cooling method is adopted. This method can reduce the fruit temperature to 1 degrees within 3~4 hours, then store it in storage. In the United States, cooling by water cooling and adding 0.010% to 0.015% active chlorine in water can effectively inhibit fungal diseases.

　 3.3 modified atmosphere storage

Cherry is resistant to high CO2 and low O2. According to the test, the suitable conditions for controlled atmosphere storage are: temperature 0 ~ 2.5 degrees C, relative humidity 90% ~ 95%, CO210% ~ 20%, O20.5% ~ 2.5%. 35 days after storage, the fruit stalk of 80% to 87% remained green. The fruit tree store in Muping County of Yantai city has a good effect in storing large purple cherry with plastic bags. It can be stored for 45~60 days at temperatures -1 ~ 0 degrees, relative humidity 90% ~ 95%, CO2 10% and O2 1%. Before the controlled atmosphere storage, the fruit needs to be pre cooled, and the temperature should be gradually increased before going public.

In addition, pre harvest calcium injection or post harvest calcium leaching can significantly increase fruit firmness, reduce decay during storage and transportation, stem rate and flesh browning. Pre harvest calcium injection can also increase Vc content and sugar acid ratio of fruits. Spraying concentration: four water calcium nitrate is 1% ~ 1.5%, calcium chloride is 0.3% ~ 0.5%. The concentration of calcium chloride is 1% to 8%, and the duration of fruit soaking depends on the concentration, about 5~60 minutes.
