Problems solved by technology

It may be because the research on the preservation of cut flowers is a very complicated subject, involving the interaction of water absorption, energy supply, growth regulation and environmental factors such as temperature, humidity and light, especially the research on the preservation of woody cut flowers has many limitations. Factors, the opening and aging characteristics of branches after cutting are relatively complicated, so the research on woody cut flower preservatives is far from meeting the market demand

Embodiment 1

[0013] The formula and dosage of the peach cut flower preservative with a volume of 1L: 50g of sucrose, 10mg of 6-BA, 250mg of 8-HQ, 4ml of triton, 20% (percentage by weight) citric acid to adjust the pH value to 5.8. And prepare as follows:

[0014] (1) 10mg of 6-BA is first dissolved in a small amount of 1mol / L NaOH solution, and stirred to fully dissolve, this is solution 1;

[0015] (2) Dissolve 250mg of 8-HQ in a small amount of absolute ethanol, heat slightly, and stir to fully dissolve, this is solution 2;

[0016] (3) Dissolve 50g of sucrose in 500ml of clear water, and stir to fully dissolve it, which is solution 3;

[0017] (4) import solutions 1 and 2 into solution 3, and add the latter solution after the previous solution and solution 3 are fully mixed, this is solution 4;

[0018] (5) Add 4ml of Triton into solution 4, and stir to make it fully mixed, and finally add water, use a volumetric flask to adjust the volume to 1L, and then adjust the pH to 5.8 with 20%...

Embodiment 2

[0035] The formula and dosage of the preservative for cut flowers with a volume of 1L: 30g of sucrose, 8mg of 6-BA, 200mg of 8-HQ, 2ml of triton, and 20% citric acid to adjust the pH to 6.0.

[0036] Preparation steps and processing method are the same as embodiment 1.

[0037] After being treated with the cut flower preservative of this embodiment, the days when the water balance value of "Huachun" peach cut flowers was zero was delayed by 1-2 days compared with the control; the full flowering rate was increased by 25.41% compared with the control; Compared with the control, the increase was not obvious; the vase life was extended by about 1d compared with the control.

Embodiment 3

[0039] The formula and dosage of the preservative for cut flowers with a volume of 1L: 40g of sucrose, 12mg of 6-BA, 300mg of 8-HQ, 6ml of triton, and 20% citric acid to adjust the pH to 5.5.

[0040] Preparation steps and processing method are the same as embodiment 1.

[0041] After being treated with the cut flower preservative of this embodiment, the days when the water balance value of "Huachun" peach cut flowers was zero was delayed by 3 days compared with the control; the full flowering rate increased by 35.41% compared with the control; the fresh weight also increased during the whole vase insertion process. Significant increase; vase life extended 2-3d compared with the control.

[0042] The nouns that appear in the description of the present invention are explained as follows:

[0043] Bud stage: the colored part accounts for half of the bud. Buds are slightly firm. The calyx tightly covers the flower buds, and the colored part of the whole flower buds is darker, an...

Abstract

The invention discloses a cut flower preservative, which contains the following components: sucrose with the final concentration between 30 and 50 g / L, 6-benzylamino adenine with the final concentration between 8 and 12 mg / L, and Triton with the final concentration between 2 and 6 mL / L, wherein pH is between 5.5 and 6.0. The cut flower preservative has the advantages of maintaining the quality of cut peach flowers, preventing the propagation of microorganisms, prolonging the vase lifespan of the peach flowers by about 1 to 4 days, improving the ornamental quality of the peach flowers and ensuring that petals are plumper and bright in color.

Description

technical field [0001] The invention relates to the field of quality maintenance of cut flowers, in particular to a fresh-keeping agent for cut flowers and application thereof. Background technique [0002] After more than 20 years of development, the flower industry has entered a period of rapid development. Cut flower production, as an important part of the flower industry, has gradually scaled up, and its variety and quantity are increasing at an alarming rate. However, for a long time, my country's cut flower production has been mainly based on popular species in Europe and America. Except for a few woody species such as cut flower roses, it is basically based on herbaceous perennial species, not ignoring the huge market potential and Chinese characteristics. The market cultivation and industrialization development of cut flowers; in addition, although my country has a vast land and great differences in climatic conditions, the distribution of cut flower production areas...
