Description

Technical Field

[0001] This invention relates to the field of flower preservatives, and in particular to a preservative for cut flowers in vases and its preparation method. Background Technology

[0002] Flower consumption is showing an increasingly strong trend, driven by reasons such as work needs, interior decoration, holiday flower delivery, and personal hobbies. The flowers purchased are usually cut flowers, arranged in vases for display, but this method of preservation is not very effective at keeping flowers fresh. Therefore, developing efficient and effective flower preservation technologies is particularly important.

[0003] Among the many types of flowers, roses, carnations, and lilies are the three most commonly chosen. Roses, belonging to the Rosaceae family, are the most popular type of flower, symbolizing love. Carnations, belonging to the Caryophyllaceae family, are the official flower for Mother's Day in many countries, and in Chinese culture, they are often used in wedding decorations. Lilies, belonging to the Liliaceae family, are also frequently used in wedding decorations and for holiday greetings because they symbolize "a long and happy marriage" and "purity and elegance." Currently, the most common preservation techniques for these three types of cut flowers mainly involve using preservatives to delay their aging. Preservatives used for flower arrangements are called vase solutions, which primarily extend the life of cut flowers by providing nutrients, sterilizing, inhibiting microbial growth, and improving the water balance of the flower stems.

[0004] Dichloroisocyanuric acid (DICA) is a slow-release chlorine-based bactericide, readily soluble in water, and produces hypochlorous acid upon dissolution. DICA is commonly used for disinfection of drinking water, swimming pool water, and environments inhabited by livestock and fish. Researchers have also investigated the preservation ability of DICA on cut gerberas using dichloroisocyanuric acid as the vase solution. Studies showed that compared to a control group using distilled water as the vase solution, the treatment group using DICA extended the lifespan of the flowers by 6.6 days and significantly improved the water metabolism of the gerberas. Therefore, DICA can indeed function as a preservative, but its short preservation time is a drawback.

[0005] As can be seen from the above description, there is an urgent need for a low-cost preservative for fresh cut flowers that can also keep them fresh for a long time. Summary of the Invention

[0006] This invention provides a preservative for fresh-cut flowers in vases to solve the aforementioned problems in the prior art.

[0007] The solution of the present invention is:

[0008] A preservative for fresh-cut flowers in vases, comprising the following raw materials in parts by weight:

[0009]

[0010] As a preferred technical solution, the bactericide is a complex of dichloroisocyanuric acid and isothiazolinone.

[0011] As a preferred technical solution, the concentration of dichloroisocyanuric acid and isothiazolinone in the bactericide is 200 mg / L, and their mass ratio is 3:1.

[0012] As a preferred technical solution, the copper salt is one of copper sulfate, copper nitrate, copper chloride, copper sulfate hydrate, copper nitrate hydrate, and copper chloride hydrate.

[0013] As a preferred technical solution, the potassium salt is one of potassium sulfate, potassium nitrate, potassium chloride, potassium carbonate, potassium bicarbonate, potassium sulfate hydrate, potassium nitrate hydrate, potassium chloride hydrate, potassium carbonate hydrate, and potassium bicarbonate hydrate.

[0014] As a preferred technical solution, the cobalt salt is one of cobalt sulfate, cobalt nitrate, cobalt chloride, cobalt acetate, cobalt sulfate hydrate, cobalt nitrate hydrate, cobalt chloride hydrate, and cobalt acetate hydrate.

[0015] As a preferred technical solution, the zinc salt is one of zinc sulfate, zinc nitrate, zinc chloride, zinc acetate, zinc sulfate hydrate, zinc nitrate hydrate, zinc chloride hydrate, and zinc acetate hydrate.

[0016] As a preferred technical solution, the calcium salt is one of calcium nitrate, calcium chloride, calcium nitrate hydrate, and calcium chloride hydrate.

[0017] The present invention also discloses a method for preparing a preservative for fresh-cut flowers in vases, comprising the following steps: adding 1000 parts by weight of distilled water to a stirring container, then adding 3-5 parts by weight of sucrose, 0.01-0.05 parts by weight of copper salt, 0.01-0.04 parts by weight of potassium salt, 0-0.015 parts by weight of cobalt salt, 0-0.03 parts by weight of zinc salt, 0.8-1 parts by weight of calcium salt and 0.05-0.2 parts by weight of bactericide to the container, and stirring to obtain the preservative for fresh-cut flowers in vases.

[0018] A fresh-cut flower vase preservative using the above-mentioned technical solution comprises: 1000 parts distilled water; 3-5 parts sucrose; 0.01-0.05 parts copper salt; 0.01-0.04 parts potassium salt; 0-0.015 parts cobalt salt; 0-0.03 parts zinc salt; 0.8-1 parts calcium salt; and 0.05-0.2 parts bactericide.

[0019] Advantages of this invention:

[0020] Adding sucrose as a nutrient; adding copper salts lowers the pH of the solution, inhibiting bacterial growth and reproduction while promoting the water absorption capacity of flowers; selecting inorganic salts such as potassium, calcium, aluminum, zinc, and copper salts increases the osmotic potential of the solution, maintains the water balance of flower branches, and delays the aging process; among them, calcium and cobalt salts also inhibit ethylene growth; calcium salts are important for plant growth and metabolism, maintaining cell integrity, and can regulate the activity of certain enzymes, transmit and induce drought signals, and improve the plant's water retention capacity, thereby ensuring that cut flowers maintain normal physiological functions and lifespan. In addition to serving as a carbon source to supplement energy, the addition of sucrose, compared to glucose, reduces the probability of contamination by bacteria because fewer microorganisms can utilize sucrose. At the same time, sucrose is a disaccharide, and the osmotic pressure it forms is lower than that formed by glucose, which further improves the water retention performance of flowers, especially improving the preservation of cut roses, carnations, and lilies.

[0021] This invention uses a complex of dichloroisocyanuric acid and isothiazolinone as a bactericide. The flower preservative is non-toxic and significantly improves the preservation ability of roses, lilies, and carnations. It has universal applicability and high economic benefits.

[0022] By mixing bactericides with other nutrients, a new vase preservative for cut roses, carnations, and lilies can be obtained, which can improve the preservation ability of these three common cut flowers and significantly extend their effective vase life. Attached Figure Description

[0023] Figure 1 This is a comparison chart of the vase life of fresh flowers in Embodiment 1 of the present invention.

[0024] Figure 2 This is a comparison chart showing the time it takes for fresh flowers to completely wither in a vase, as shown in Embodiment 1 of the present invention. Detailed Implementation

[0025] This invention provides a preservative for fresh-cut flowers in vases to solve the problems mentioned in the background art.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific embodiments.

[0027] Example 1:

[0028] This study compares the preservation effects of the flower preservative of this invention on fresh-cut flowers of different ornamental flowers.

[0029] The control group received only distilled water, while the experimental group received the preservative from this regimen. The formula contained the following components by mass percentage: sucrose 4 g / L, copper salt 20 mg / L, potassium salt 25 mg / L, cobalt salt 7.5 mg / L, zinc salt 15 mg / L, calcium salt 600 mg / L, a complex of dichloroisocyanuric acid and isothiazolinone 200 mg / L (ratio 3:1), and 1000 mL of distilled water.

[0030] The test results are as follows Figure 1 , 2 As shown;

[0031] It can be seen that the vase life and time to complete wilting of cut flowers in the preservation group were extended to varying degrees compared with the control group. Among the seven selected ornamental flowers, roses, carnations, and lilies showed the most significant preservation effects. In terms of vase life, roses increased from 7 days to 15 days, an extension of 1.14 times; carnations increased from 15 days to 26 days, an extension of 0.73 times; and lilies increased from 5 days to 10 days, an extension of 100%. The time to complete wilting also showed a similar trend.

[0032] Therefore, it is evident that the preservative of this invention has a prominent preservation effect on three types of cut flowers: roses, carnations, and lilies. This is mainly due to the addition of a high proportion of sucrose and calcium salts. The addition of sucrose, in addition to serving as a carbon source to supplement energy, also reduces the probability of microbial contamination to some extent compared to glucose, as fewer microorganisms can utilize sucrose. Furthermore, sucrose is a disaccharide, resulting in a lower osmotic pressure compared to glucose, which further enhances the water retention capacity of the flowers. Calcium salts are crucial for plant growth and metabolism, maintaining cell integrity. Calcium also regulates the activity of corresponding enzymes during growth, transmits and induces drought signals, and improves the plant's water retention capacity, thereby extending the lifespan of cut flowers.

[0033] Example 2:

[0034] Add 1000 parts by weight of distilled water to a mixing container, then add 5 parts by weight of sucrose, 0.05 parts by weight of copper salt, 0.04 parts by weight of potassium salt, 0.015 parts by weight of cobalt salt, 0.03 parts by weight of zinc salt, 1 part by weight of calcium salt and 0.2 parts by weight of bactericide to the container, and stir well to obtain a fresh-cut flower vase preservative.

[0035] The bactericide is a complex of dichloroisocyanuric acid and isothiazolinone.

[0036] The concentration of dichloroisocyanuric acid and isothiazolinone in the bactericide is 200 mg / L, and their mass ratio is 3:1.

[0037] The copper salt is one of copper sulfate, copper nitrate, copper chloride, copper sulfate hydrate, copper nitrate hydrate, and copper chloride hydrate.

[0038] The potassium salt is one of potassium sulfate, potassium nitrate, potassium chloride, potassium carbonate, potassium bicarbonate, potassium sulfate hydrate, potassium nitrate hydrate, potassium chloride hydrate, potassium carbonate hydrate, and potassium bicarbonate hydrate.

[0039] The cobalt salt is one of cobalt sulfate, cobalt nitrate, cobalt chloride, cobalt acetate, cobalt sulfate hydrate, cobalt nitrate hydrate, cobalt chloride hydrate, and cobalt acetate hydrate.

[0044] The bactericide is a complex of dichloroisocyanuric acid and isothiazolinone.

[0045] The concentration of dichloroisocyanuric acid and isothiazolinone in the bactericide is 200 mg / L, and their mass ratio is 3:1.

[0046] The copper salt is one of copper sulfate, copper nitrate, copper chloride, copper sulfate hydrate, copper nitrate hydrate, and copper chloride hydrate.

[0050] The calcium salt is one of calcium nitrate, calcium chloride, calcium nitrate hydrate, or calcium chloride hydrate.

[0051] Example 4:

[0052] The effects of dichloroisocyanuric acid and / or isothiazolinone on bactericidal efficacy were investigated.

[0053] Implementation Group 1: A flower preservative comprising the following components by mass percentage: 4 g / L sucrose, 20 mg / L copper salt, 25 mg / L potassium salt, 7.5 mg / L cobalt salt, 15 mg / L zinc salt, 600 mg / L calcium salt, 50 mg / L dichloroisocyanuric acid-isothiazolinone complex (ratio 1:1), and 1000 mL distilled water.

[0054] Implementation Group 2: A flower preservative comprising the following components by mass percentage: 4 g / L sucrose, 20 mg / L copper salt, 25 mg / L potassium salt, 7.5 mg / L cobalt salt, 15 mg / L zinc salt, 600 mg / L calcium salt, 125 mg / L of a complex of dichloroisocyanuric acid and isothiazolinone (in a ratio of 4:1), and 1000 mL distilled water.

[0055] Implementation Group 3: A flower preservative comprising the following components by mass percentage: 4 g / L sucrose, 20 mg / L copper salt, 25 mg / L potassium salt, 7.5 mg / L cobalt salt, 15 mg / L zinc salt, 600 mg / L calcium salt, 200 mg / L of a complex of dichloroisocyanuric acid and isothiazolinone (in a ratio of 3:1), and 1000 mL distilled water.

[0056] Comparative Group 1: A flower preservative containing the following components by weight percentage: 4 g / L sucrose, 20 mg / L copper salt, 40 mg / L potassium salt, 7.5 mg / L cobalt salt, 15 mg / L zinc salt, 600 mg / L calcium salt, 200 mg / L dichloroisocyanuric acid, and 1000 mL distilled water.

[0057] Comparative Group 2: A flower preservative containing the following components by weight percentage: 4 g / L sucrose, 20 mg / L copper salt, 40 mg / L potassium salt, 7.5 mg / L cobalt salt, 15 mg / L zinc salt, 600 mg / L calcium salt, 200 mg / L isothiazolinone, and 1000 mL distilled water.

[0058] Comparative Group 3: A flower preservative containing the following components by weight percentage: 4 g / L sucrose, 20 mg / L copper salt, 40 mg / L potassium salt, 7.5 mg / L cobalt salt, 15 mg / L zinc salt, 600 mg / L calcium salt, and 1000 mL distilled water.

[0059] The fresh flowers from different groups were labeled, and 1000 mL of the above preservative was added. The same copper, potassium, cobalt, zinc, and calcium salts were used in both the control and experimental groups. Fresh-cut roses, carnations, and lilies were used as test subjects. The diameter of the flower buds and the amount of wilting after 10 days in the vase were used as evaluation indicators. The experimental group was set up with three replicates, with 6 flowers in each group. The experimental results are shown in Table 1 below:

[0060] Table 1

[0061]

[0062]

[0063] As shown in the control group table above, without preservatives, 100% of roses and lilies wilted after 10 days of cultivation, while 33.3% of carnations wilted. Compared to control group 3 (without fungicide), the addition of the fungicides dichloroisocyanuric acid or isothiazolinone inhibited microbial growth. The antibacterial effect of dichloroisocyanuric acid alone (control group 1) was slightly weaker than that of isothiazolinone alone (control group 2), but the addition of isothiazolinone alone (control group 2) affected the preservation effect of cut flowers, decreasing the maximum flower diameter and increasing wilting. Since dichloroisocyanuric acid can inhibit the growth of various pathogenic bacteria and help improve the water retention of cut flowers, while isothiazolinone can effectively inhibit the growth of eukaryotic algae and fungi, combining the two yields superior preservation and fungicidal effects. When a compound of dichloroisocyanuric acid and isothiazolinone at a concentration of 200 mg / L (in a ratio of 3:1) was added, the antibacterial effect was good; and an unexpected effect was produced, which extended the vase life of cut flowers. After 10 days of cultivation, the wilting rate of roses was 16.7%, carnations were 0.0%, and lilies were 16.7%. The experimental groups above show that when the concentration of the bactericide compound of dichloroisocyanuric acid and isothiazolinone in the preservative is 200 mg / L and the ratio is 3:1, the optimal preservation and bactericidal effect on cut roses, carnations, and lilies is achieved, effectively extending the vase life of these three types of cut flowers.
