Storage Technology of Peach
Some peach varieties mature in the summer high temperature season, and their exploitable maturity and edible maturity reach almost at the same time; in addition, the fruit is soft and juicy, and the storage resistance is poor. However, there are great differences in storage tolerance among varieties, honey peach has the worst storage tolerance, which can only be stored for about one week, while fat peach, winter peach, Qingzhou peach and other late-maturing varieties are more resistant to storage. The problems that easy to occur during storage of peach are: overripening and softening, rot caused by bacteria, and chilling injury. The main technical measures adopted in production are as follows:
1. Precool the postharvest fruit immediately: soak the fruit in 0. 5-1 ℃ of cold water for 30-40 minutes or cool it with cold air.
2, anticorrosion treatment: the fruit is soaked with the mixture of Bentate 100 × 0.000001-1000 × 0.000001 and 450 × 0.000001-900 × 0.000001 dichloronitroaniline.
3. Variable temperature treatment: the use of variable temperature treatment during storage can reduce the incidence of chilling injury and prolong the storage life of peach fruit.
4. Controlled atmosphere storage: peach is stored in 0.5-0 ℃, 1% oxygen and 5% carbon dioxide, and the effect is good.

Orangery tube after fruit harvest
During the annual growth cycle, adult citrus trees experienced flower bud differentiation, flowering, fruit setting, physiological fruit drop, fruit expansion, three times of shoot and shoot growth, three root growth peaks, which consumed a lot of energy and nutrients, seriously weakened the tree vigor, and all kinds of diseases and insect residues concentrated in them, which brought many disadvantages to the growth and fruit of citrus trees in the next year. Therefore, it is of great significance to strengthen the cultivation and management of orange orchard after fruit picking and restore the tree vigor rapidly for citrus production in the next year. The author believes that the orange orchard management after fruit picking should focus on the implementation of the following technologies
