Problems solved by technology

8-hydroxyquinoline salt not only has a bactericidal effect, but also can inhibit the formation of ethylene in fresh-cut flowers. It is a widely used preservative component. However, the bactericidal effect of 8-hydroxyquinoline salt cannot meet the requirements of long-term fresh-keeping.

Embodiment 1

[0009] Embodiment 1: The present invention is achieved in this way, consisting of bromide cetylpyridine (Cetylpyridine bromide, CPB), 8-hydroxyquinoline sulfate (8-hydroxyquinolinesulfate, 8-HQS), wherein, bromide cetyl The content of alkylpyridine is 0.1-0.3 g / L, and the content of 8-hydroxyquinoline sulfate is 0.3-0.6 g / L.

Embodiment 2

[0010] Embodiment 2: In this embodiment, citric acid is added on the basis of embodiment 1, and the content of citric acid is 0.2-0.5 g / L.

Embodiment 3

[0011] Embodiment 3: In this embodiment, sucrose is added on the basis of embodiment 2, and the content of sucrose is 30-50 g / L.

[0012] Now compare the preservatives of the above examples with clear water and preservatives that do not contain cetylpyridinium bromide. Table 1 is the composition content of four kinds of liquids. Table 2 is the comparison of the fresh-cut vase life and the largest flower stem of each group of liquids used in flower arrangement. The vase life of cut flowers is the number of days between the start of treatment and the end of the ornamental life of cut flowers. The end of vase life is judged by the initial wilting of the flowers, the outer edge of the petals or the center of the flower starting to turn brown, and the loss of ornamental value as a sign.

Abstract

An antistaling agent for the fresh flower is proportionally prepared from bromocetylpyridine, 8-hydroxyquinoline sulfate, and water. Its advantages are no poison and no environmental pollution.

Description

Technical field: [0001] The invention relates to a plant fresh-keeping agent. Background technique: [0002] The reproduction of microorganisms is one of the main factors affecting the fresh-keeping quality of cut flowers. Therefore, more fungicides are added to the preservatives currently used, including 8-hydroxyquinoline salts, silver salts, carbendazim, thiophanate, penicillin, quaternary ammonium compounds, Surfactant etc. Among them, quaternary ammonium compounds are relatively stable and long-lasting, and generally do not cause toxicity to flower materials, and are widely used as fungicides. Surfactants can promote flower materials to absorb water. Currently, ionic higher alcohols and non-ionic polyoxyethylene lauryl ether are used in the research of cut flower preservation. 8-hydroxyquinoline salt not only has a bactericidal effect, but also can inhibit the formation of ethylene in fresh-cut flowers. It is a widely used preservative component. However, the bacteric...
