Abstract

The invention discloses a preservative for Chinese herbaceous peony cut flower vase. The preservative is prepared from graphene oxide, gibberellin, calcium salt, citric acid, cane sugar and water. Sucrose is used as an exogenous nutrient donor, sound field energy is provided for fresh cut flowers, the flowering rate is increased, and the service life of an inserted bottle is prolonged; citric acidis utilized, so that the pH of the preservative is reduced, bacterial reproduction is inhibited, and blockage of cut flower conduits is reduced; graphene oxide is utilized, and due to the large surface area and hydrophilicity, the graphene oxide has the functions of adsorbing microorganisms, conveying moisture and nutrients and enhancing the water absorption capacity of stems; calcium salt is adopted to increase osmotic pressure of the water aqua and keep moisture balance; and the gibberellin plays a positive role in relieving membrane lipid peroxidation, the vase life of the peony cut flowers is effectively prolonged, and the blooming quality of the cut flowers is ensured.

Description

technical field [0001] The invention belongs to the technical field of preservation and utilization of fresh-cut flowers, and in particular relates to a fresh-keeping agent for cut peony vases and a using method thereof. Background technique [0002] Peony (Paeonia lactiflora Pall.) is a perennial herbaceous plant of Paeoniaceae. It has large and colorful flowers, various flower types, and high ornamental value. It symbolizes beauty, love and auspiciousness. Its cut flowers are suitable for festive occasions such as banquets, celebrations and festivals. In recent years, they have been widely developed for the high-end fresh cut flower market. The biggest bottleneck problem of peony cut flowers is the short flowering period. Currently, the preservation technology for peony cut flowers cannot be extended The vase life of cut peony flowers after harvest, the ornamental quality of cut flowers is low. Contents of the invention [0003] Aiming at the technical problems existing...
