Effect detection

In the experiment, "Silver Thread Embroidered Red Robe" purchased from Heze, Shandong Province was selected as the test material; the flower branches with robust flower branches, no diseases and insect pests, and flower buds in the bud stage were selected and placed in a bucket filled with distilled water for 1.5-2 hours, and then placed in water for 1.5-2 hours. Each flower branch is obliquely cut at 35°-45° to a length of 35-40 cm to obtain fresh cut flowers.

Using the preservatives described in Examples 1-14, the preservatives with the component contents shown in Table 1 were respectively dissolved in water to prepare fourteen groups of preservatives; Effect, using no preservative, only distilled water as a blank control group:

Table 2 Preservative component content table

Pour the above-mentioned fourteen groups of fresh-keeping liquids and distilled water of the control test group into 250mL conical flasks, wherein the volume of the fourteen groups of fresh-keeping liquids is 150mL, and the volume of distilled water in the blank control group is 150mL; For fresh cut flowers treated, make sure that the preservative or distilled water submerges the cut flowers by 3-5cm; the bottle insertion environment is about 23-26°C, and the humidity is 60%-70%; observe the fresh-keeping effect of each formula, the specific fresh-keeping effect See Table 1; the preservative liquid used in each group test gradually decreases with time, and the corresponding equal amount of preservative liquid or distilled water should be added to each group every two days.

Table 1 The effect of fresh-cut vase insertion

From table 2, above-mentioned each group of test preservative liquid is compared with distilled water treatment, no matter in bottle insertion life, or in flower diameter and flowering quality, the use effect of fresh cut flower preservative of the present invention is obviously better than that without reagent treatment, especially The concentration used in the first group significantly extended the life of fresh cut flowers, increased the flower diameter and improved the flowering quality; the existing fresh cut flowers had a lifespan of 5-6 days under the condition of no treatment, while the present invention The nutrient solution can make its lifespan reach 7.5-9 days. Wherein, when using the preservative in Example 1 as the preservative liquid, the blooming days of the cut flower varieties of red robe peony with silver thread embroidery can reach 7 days, and the total bottle insertion life can reach 9 days.

As shown in accompanying drawing 1, provided in accompanying drawing 1 utilizes the antistaling agent in embodiment 1 and the comparison chart of the effect of bottle insertion of the cut peony flowers of blank control; As can be seen from accompanying drawing 1, on the sixth day, distilled water treatment The control group lost the ornamental value and ended the vase life, while the cut flowers treated with the formula of the first group lost their ornamental value and ended the vase life until the tenth day. One treatment group worked best.
