Fresh cut flower preservative and preparation method thereof

Abstract

The invention discloses an anti-staling agent for freshly cut flowers and a preparation method thereof. The existing anti-staling agents with relatively good anti-staling effect need to be prepared when required, and can not be used conveniently and have short preservation time and are hardly applicable to large-scale production of industrialization. The anti-staling agent stated by the invention comprises calcium dihydrogen phosphate, salicylate, 8-hydroxyquinoline, citric acid, nano-silver-titanium material and the mixture of cytokinin and growth hormone. The anti-staling agent acquired by mixing the materials of the invention has excellent anti-staling effect, and the effect of protecting flowers and leaves can compete with a foreign anti-staling agent Chrysal; the anti-staling agent has long preservation time when protected from light, does not have to be freshly prepared as ordered and can be used conveniently; the anti-staling agent can promote the cross or longitudinal growth of plants, thereby granting the flowers with a diauxic growth opportunity after being cut from the main body.

Description

technical field

[0001] The invention relates to a fresh-cut flower preservative and a preparation method thereof. Background technique

[0002] The cut flowers and cut leaves of fresh flowers are easy to deteriorate, so preservatives are needed to keep the cut flowers and cut leaves fresh. The Chinese patent No. ZL03133519.5 discloses a cut flower preservative, which has an obvious preservation effect on fresh cut flowers, but it will change color easily, except that silver ions will change color when exposed to light, and thiosulfate is not very stable. Sulfur is easy to form precipitation, which affects the appearance. STS needs to be prepared as needed, which is very inconvenient to use. It is best to use the prepared solution immediately. If it is not used immediately, it should be stored away from light. It can only be stored in a dark environment at 20-30°C 4 It is difficult to be used in industrialized large-scale production.

Examples

Embodiment 1

[0013] To a liter of water solution add:

[0014] Glucose: 5.5g Calcium dihydrogen phosphate: 0.01g

[0015] Potassium salicylate: 0.03g Nano silver titanium material: 0.003g

[0016] 8-hydroxyquinoline: 0.21g 1:1 mixture of 6-BA and IBA: 2ppm

[0017] Citric acid: 0.17g Sodium benzoate: 0.01g

[0018] Silver nitrate: 0.05g Ammonium nitrate: 0.01g

[0019] EDTA: 0.10g

[0020] This formula is suitable for ethylene-sensitive flowers, such as chrysanthemums, carnations, impatiens, roses, sunflowers, tulips, snapdragons, violets, daffodils, orchids, and bellflowers.

[0021] The preparation method of the preservative is as follows: 1) Dissolve potassium salicylate, sodium benzoate and glucose in water and stir evenly to form solution 1; 2) Dissolve citric acid in water, dissolve EDTA in water, and add ammonium nitrate , and then add 8-hydroxyquinoline to dissolve, which is solution 2; 3) dissolve calcium dihydrogen phosphate in water, add silver nitrate, mix and dissolve, an...

Embodiment 2

[0023] To a liter of water solution add:

[0024] Glucose: 2.0g Calcium dihydrogen phosphate: 0.02g

[0025] Potassium salicylate: 0.01g Nano silver titanium material: 0.008g

[0026] 8-hydroxyquinoline: 0.15g 1:1 mixture of 6-BA and IBA: 5ppm

[0027] Citric acid: 0.15g Sodium benzoate: 0.01g

[0028] Silver nitrate: 0.02g Ammonium nitrate: 0.015g

[0029] EDTA: 0.10g

[0030] This formula is suitable for flowers that are sensitive to sugar content and relatively sensitive to ethylene, such as roses, roses, chrysanthemums, etc.

Embodiment 3

[0032] To a liter of water solution add:

[0033] Glucose: 10g Calcium dihydrogen phosphate: 0.15g

[0034] Potassium salicylate: 0.02g Nano silver titanium material: 0.025g

[0035] 8-hydroxyquinoline: 0.15g 1:1 mixture of 6-BA and IBA: 10ppm

[0036] Citric acid: 0.18g Sodium benzoate: 0.15g

[0037] Silver nitrate: 0.005g Ammonium nitrate: 0.20g

[0038] EDTA: 0.09g

[0039] This formula is suitable for fresh cut flowers that require high content of phosphorus and potassium, such as nandina and other ornamental flowers.
