Effect detection
The 'silver thread embroidery red robe' purchased from lotus in Shandong is selected as a test material for the test; selecting strong flower branches without diseases and insect pests and bud growth period, putting the flower branches in a barrel filled with distilled water for rehydration for 1.5-2h, and beveling each flower branch to 35-40cm in water at 35-45 degrees to obtain fresh cut flowers.
The preservatives described in examples 1-14 were dissolved in water to prepare fourteen groups of preservatives according to the component contents shown in table 1 below; in order to more obviously show the excellent effect of the preservative, the preservative is not added, and only distilled water is used as a blank control group:
TABLE 2 antistaling agent component content table
Pouring the fourteen groups of fresh-keeping liquid and distilled water of a control test group into 250m L conical flasks respectively, wherein the volumes of the fourteen groups of fresh-keeping liquid are 150m L, the volume of the distilled water in a blank control group is 150m L, inserting the treated fresh cut flowers into the flasks respectively to ensure that the fresh-keeping agent or the distilled water submerges the cut of the fresh cut flowers by 3-5cm, adopting the environment of bottle insertion at about 23-26 ℃ and the humidity of 60-70%, observing the fresh-keeping effect of each formula, wherein the specific fresh-keeping effect is shown in table 1, the fresh-keeping liquid used in each group of tests gradually decreases along with the extension of time, and adding the corresponding equal amount of fresh-keeping liquid or distilled water to each group every two days.
TABLE 1 table for inserting effect of fresh-cut flower
From table 2, compared with the distilled water treatment, the fresh-keeping agent for fresh cut flowers of the above groups of test fresh-keeping solutions has the advantages that the using effect of the fresh-keeping agent for fresh cut flowers is obviously superior to that of the fresh cut flowers without reagent treatment in both the bottle-inserting life and the flower diameter flowering quality, especially the concentration used in the first group is higher, the life of the fresh cut flowers is prolonged obviously, the flower diameter is increased, and the flowering quality is improved; the service life of the bottle can be 5-6 days under the condition of no treatment of the existing fresh cut flowers, and the service life of the nutrient solution can be 7.5-9 days. Wherein, when the preservative in the embodiment 1 is adopted as a preservative solution, the full-bloom days of the cut flower variety of the silver-thread embroidered Paeonia lactiflora can reach 7 days, and the total vase service life can reach 9 days.
As shown in attached figure 1, a comparison graph of the vase effect of cut peony flowers using the preservative and the blank control in example 1 is shown in attached figure 1; as can be seen from fig. 1, on the sixth day, the control group treated with distilled water lost the ornamental value and ended the vase life, and until the tenth day, the cut flowers treated with the first group of formula lost the ornamental value and ended the vase life, and overall, the first group of treatment groups had the best effect by integrating factors such as flower diameter, blooming time, vase life, and the like.
The invention provides a cut peony flower vase preservative which utilizes sucrose as an exogenous nutrition donor to provide growth energy for fresh cut flowers, improve flowering rate and prolong the service life of vase; by using citric acid, the pH value of the preservative is reduced, the bacterial reproduction is inhibited, and the blockage of cut flower ducts is reduced; the graphene oxide has the advantages that due to the large surface area and the hydrophilicity, the graphene oxide can adsorb microorganisms, convey water and nutrients and enhance the water absorption capacity of the stems; the calcium salt is adopted to increase the osmotic pressure of the water aqua and keep the water balance; the gibberellin has an active effect on relieving membrane lipid peroxidation, so that water loss after the peony cut flowers are harvested is avoided, the vase life of the peony cut flowers is effectively prolonged, and the opening quality of the cut flowers is ensured.
The cut peony vase preservative disclosed by the invention has the advantages that the raw materials are cheap and easy to obtain, the nutrition is comprehensive, and the cut peony vase life is prolonged by 1.7-3.4 days; the preparation process is simple; the paint is environment-friendly and efficient, and does not contain silver salt which is toxic and pollutes the environment; the use of toxic 8-hydroxyquinoline is avoided.
Finally, it should be noted that: the foregoing detailed description has described preferred embodiments of the present invention in detail, rather than by way of limitation; the invention is also applicable to other peony varieties. Many modifications and variations will be apparent to those of ordinary skill in the art in light of the above teachings without undue experimentation.
