Check once a month after storage. If there are rotten fruits, remove them in time. This storage method can be stored until March and April of the next year. This method uses wet sand and needs to strictly control the moisture content. Improper control will easily lead to black skin and rotten fruits.
[0007] (4) Bag storage: put the pre-cooled pomegranate treated with fungicide into a polyethylene plastic film bag, tie the bag mouth, and place it in a cool room. This method needs to sterilize the pomegranate in advance, which is time-consuming and laborious
This method requires disinfection of cold storage, pre-cooling of baskets, and disinfection of pressure-resistant containers, which is time-consuming and laborious, and the cost of disinfection is high.
[0009] In addition, cold storage and controlled atmosphere storage have gradually developed in recent years, but these methods generally have the problem of short storage period and serious decline in the quality of pomegranate fruit after storage, so they cannot meet the needs of the market

Embodiment 1

[0032] A method for keeping fresh on pomegranate branches, the steps are as follows:

[0033] (1) When picking pomegranates from September to October every year, first remove the diseased and cracked fruits, and then spray the pomegranate tree with 2.5% urea to make the leaves on the tree fall, and then spray the fungicide chlorothalonil , 70% wettable powder 600 times liquid, and finally spray 0.5% high-energy calcium solution on the pomegranate fruit;

[0034] (2) bag the pomegranate, first put the foam net bag, then put the PE plastic bag on the outside, then spray the 2,4-D and the mass percentage of 0.5% on the pomegranate fruit handle with a concentration of 40mg / L Borax solution, evenly spray zeatin solution on the pomegranate stalk after 15 days, the concentration of zeatin solution is 20 μmol / L;

[0035] (3) Pick in bags in mid-November, and store in cartons after picking.

[0036] After the pomegranate is picked, it continues to be stored in a cold storage for rout...

Abstract

The invention relates to a fresh-keeping method of a pomegranate on a branch, which comprises the following steps of: firstly, defoliating a tree body by using a urea solution, then sterilizing the fruits and spraying a calcium preparation, spraying a plant growth regulator and a zein solution on pomegranate fruit stems after a picking season to improve the freshness of the pomegranate, the pomegranate rind is more smooth and fresh, the browning inside and outside the fruit is avoided, the time of the fruit on the tree body is prolonged, the picking of the fruit is delayed, not only can the fruit absorb the nutrition of the tree body more fully, but also the freshness of the rind and flavor of the fruit can be ensured, the decay of the fruit after picking is delayed, thereby prolonging theshelf life of the fruit.

Description

technical field [0001] The invention relates to a fresh-keeping method for pomegranate branches, belonging to the technical field of fruit fresh-keeping.
