Problems solved by technology

[0004] During post-harvest water culture of gerbera, due to the large and heavy inflorescences, the normal water balance between the flower branch and the parent body is destroyed, which accelerates the aging and wilting of cut flowers, and is prone to bending neck, fresh weight drop, wilting and other phenomena. , shorten the lifespan and ornamental value
Although a large number of fresh-keeping agents have been sold on the market, silver nitrate is added in the formula, which is not only expensive but also has certain toxicity and is easy to pollute the environment. Flower preservatives are not ideal for keeping gerbera flowers fresh

Embodiment 1

[0014] A flower preservative, which is based on the concentration of each active ingredient: the concentration of sucrose is 13-16g / L, the concentration of 8-HQ is 90mg / L, the concentration of VC is 6mmol / L, and the concentration of 6-BA is 8mg / L. L and CaCl 2 The concentration is 26mmol / L, is allocated into the solution of 250mL with distilled water, and the pH value of this solution is adjusted to 4 simultaneously, obtains the fresh flower preservative of embodiment 1.

Embodiment 2

[0016] A flower preservative, which is based on the concentration of each active ingredient: the concentration of sucrose is 13-16g / L, the concentration of 8-HQ is 110mg / L, the concentration of VC is 3mmol / L, and the concentration of 6-BA is 12mg / L. L and CaCl 2 The concentration is 24mmol / L, is allocated into the solution of 250mL with distilled water, and the pH value of this solution is adjusted to 4 at the same time, obtains the fresh flower preservative of embodiment 2.

Embodiment 3

[0018] A kind of flower preservative, it is according to the concentration of each active ingredient: the concentration of sucrose is 15g / L, the concentration of 8-HQ is 100mg / L, the concentration of VC is 5mmol / L, the concentration of 6-BA is 10mg / L and CaCl 2 The concentration is 25mmol / L, is allocated into the solution of 250mL with distilled water, and the pH value of this solution is adjusted to 4 simultaneously, obtains the flower preservative of embodiment 3.

Abstract

The invention discloses a fresh flower preservative. The fresh flower preservative comprises the following effective ingredients: sucrose with the concentration of 13-16g / L, 8-HQ with the concentration of 90-110mg / L, VC with the concentration of 3-6mmol / L, 6-BA with the concentration of 8-12mg / L and CaCl2 with the concentration of 24-26mmol / L. The fresh flower preservative disclosed by the invention has the advantages that CaCl2 at certain concentration added can effectively inhibit decomposition of anthocyanin in gerbera jamesonii, maintains fullness of cells, retards damage and reduces penetration rate of cells, and other effective ingredients are combined, so that the fresh flower preservative has excellent preservation effect on gerbera jamesonii.

Description

technical field [0001] The invention relates to the field of plant growth regulators, in particular to a flower preservative and a preparation method thereof. Background technique [0002] Gerbera is a perennial herb of the genus Gerbera in the family Asteraceae, and is one of the common cut flowers. Because of its huge flowers, tall and straight flower branches, and rich colors, it is favored by consumers. Gerbera has rich and bright colors, various flower shapes, beautiful charm and strong decoration. It can bloom continuously every year in warm regions, saves labor in cultivation, and is resistant to long-distance transportation. The main cut flower species cultivated. [0003] The disadvantage of using vases to insert fresh cut flowers is that the flowers wither prematurely and the viewing time is relatively short, so how to prolong the life of cut flowers and keep a long viewing period has become an urgent problem to be solved, and fresh cut flower preservation soluti...
