Embodiment 1

[0045] The fresh-keeping method of cut peony flowers of this embodiment includes the following steps:

[0046] 1) Move the cut peony flowers to the laboratory for rehydration within 1 hour after picking, and cut them diagonally in the water to about 30cm with sterile scissors, and leave two leaves of the same size on the top of each branch for use;

[0047] 2) Insert the cut peony vase into the glass container containing the fresh-keeping liquid and place it in an ultrasonic cleaner with 80W ultrasonic power for 20min; then fumigate in a closed container with 1-MCP for 13h, and the fumigation temperature is 15℃ The concentration of citric acid in the above-mentioned preservation liquid is 200mg / L, the concentration of 8-hydroxyquinoline is 200mg / L, the concentration of calcium chloride is 150mg / L, and the mass concentration of sucrose is 4%; inside the above-mentioned airtight container 1- The concentration of MCP is 900nL / L;

[0048] 3) Step 2) After the fumigation treatment, inser...

Embodiment 2-5

[0050] The fresh-keeping method of cut peony flowers in Example 2-5 is different from Example 1 only in that the ultrasonic time is different, as shown in Table 1 for details.

Embodiment 6-9

[0061] The fresh-keeping method of the cut peony flowers in Examples 6-9 is different from that in Example 1 only in the ultrasonic power, as shown in Table 2 for details.

Ultrasonic power

Example 6

20W

Example 7

[0064] Examples 1, 6-9 and Comparative Example 1 The relationship between the fresh weight change rate of cut flowers and the ultrasonic power is as follows figure 2 Shown. Where CK corresponds to Comparative Example 1.

[0065] by figure 2 It can be seen that the fresh weight changes of all cut vases during the insertion period showed a single peak trend, except for the 80W ultrasonic treatment, the fresh weight changes of other treatments all reached the peak on the second day of the insertion. The change rate of fresh weight of cut flowers in the control group (CK) was basically lower than that of cut flowers treated with ultrasound. After the third day, the ...

Abstract

The invention relates to a preserving method for cut-flowers and belongs to the technical field of cut-flower preservation. The preserving method for cut-flowers comprises the following steps: inserting a cut-flower bottle into a preserving liquid for ultrasonic treatment for 10-50 min; and then suffocating the cut-flower bottle in a 1-methyl cyclopropene gas atmosphere for 8-30 h. According to the preserving method for cut-flowers provided by the invention, the fresh weight of the cut-flowers is reduced and the reducing degree of the water balancing value is reduced, generation of MDA in pedals is inhibited, decomposition of soluble proteins is alleviated, decrease of permeability of pedal membranes is delayed, the intactness of the cell membranes is better maintained, and the ornamentalvalue of the cut-flowers is improved greatly, thereby providing a new concept for postharvested delayed preservation of horticultural products such as peony.

Description

Technical field [0001] The invention relates to a fresh-keeping method for cut flowers, belonging to the technical field of fresh-keeping cut flowers. Background technique [0002] In recent years, the production and consumption of fresh cut flowers in the world and in my country have risen rapidly. The annual output of fresh cut flowers in my country reached 3.7 billion branches, an average annual increase of 29.25%. The research on the postharvest physiology and technology of cut flowers at home and abroad has made great progress in recent years, but the research on the preservation of some cut peony flowers is not deep enough. [0003] Peony, as a traditional famous flower in my country, is magnificent and colorful. However, its ornamental value is affected to a certain extent due to many restrictions such as short flowering period and difficult storage. Research on flower preservation is very popular at home and abroad, and methods such as low-temperature storage, preservativ...
