Description

Technical Field

[0001] The present application relates to the field of flower care products, and more specifically, to an aerosol flower nutrition spray and a preparation method thereof. Background Art

[0002] In the field of flower maintenance, the use of nutrients is crucial to prolong the shelf life of flowers and improve their ornamental value. However, most of the existing flower nutrients have problems such as complicated operation process, low absorption efficiency, difficulty in carrying and short shelf life, which limit the effectiveness and convenience of flower nutrients in practical applications.

[0003] Traditional flower nutrients are mostly in liquid form, which requires mixing according to the proportion when using them, and using tools such as measuring cups to accurately measure the dosage and water consumption. This process is not only cumbersome, but also may affect the effect of the nutrients if they are not mixed properly.

[0004] In addition, liquid nutrients are mainly absorbed through flower stems. For some flowers with thin stems, high degree of lignification or damage, the absorption speed is slow and the absorption amount is limited. This results in the nutrients not being used by flowers in a timely and effective manner, affecting the growth and preservation of flowers. Summary of the invention

[0005] In order to solve the above problems, the present application provides an aerosol-type flower nutrition spray and a preparation method thereof. The aerosol-type flower nutrition spray provided in the present application has the advantages of simple operation, high absorption efficiency, and good effect of promoting flower growth.

[0006] In the first aspect, the present application provides an aerosol-type flower nutrition spray, which adopts the following technical solution: An aerosol-type flower nutrient spray comprises a nutrient component and a propellant, wherein the volume ratio of the nutrient component to the propellant is (20-30):1; The nutrients include the following components by mass percentage: 1-10% carbohydrate supplement, 0.1-1% fungicide, 0.1-0.5% pH regulator, 0.01-0.1% growth regulator, 0.1-0.5% trace element supplement, 0.01-0.2% preservative, 3-8% osmotic agent, 5-10% plant fermentation liquid, solvent; The fermentation raw materials of the plant fermentation liquid include shiitake mushrooms, cactus and mint, and the mass ratio of shiitake mushrooms, cactus and mint is 1: (0.8-1.1): (0.1-0.4).

[0007] Aerosol nutrient sprays effectively simplify the operation process compared to liquid nutrient agents. Users only need to gently press the nozzle to spray the nutrient solution evenly on the flowers and leaves. There is no need for complicated mixing process, thus improving the convenience of use.

[0008] Aerosol nutrient spray can be sprayed directly on the leaves and petals of flowers, quickly absorbing nutrients through the stomata of the leaves, providing flowers with more timely and effective nutrient supplements. It is especially suitable for flowers that are in urgent need of nutrient supplements.

[0009] The present application uses plant fermentation liquid made from specially formulated mushrooms, cacti, and mint. During the mixed fermentation process, the natural microorganisms in cacti, mint, and mushrooms and the added fermentation agent together form a complex microbial community. These microorganisms produce a series of metabolites that are beneficial to the growth of flowers, such as amino acids, organic acids, enzymes, and vitamins, by decomposing and transforming organic matter in the raw materials. These microbial metabolites work together in the fermentation liquid to promote the growth and development of flowers, stimulate the growth and development of the roots of flowers, and make the roots more developed and strong. It helps flowers to better absorb water and nutrients in the soil, thereby increasing their growth rate and stress resistance.

[0010] Moreover, during the spraying process, part of the nutrient spray will fall into the soil. The organic acids and enzymes in the plant fermentation liquid can promote the formation of soil aggregate structure, improve soil permeability, and facilitate the respiration and nutrient absorption of the flower roots. At the same time, the nutrients in the fermentation liquid can directly supply the roots, promote root growth, increase the number of root hairs, and improve the root system's ability to absorb water and nutrients.

[0011] Preferably, in the fermentation raw materials of the plant fermentation liquid, the mass ratio of shiitake mushrooms, cactus and mint is 1:1:0.2.

[0012] By adopting the above technical scheme, the mass ratio of shiitake mushrooms, cactus and mint is further limited, which helps to ferment and obtain a plant fermentation liquid with more complete and harmonious synergy of active substances, thereby better providing nutrients for flowers and stimulating their growth and development.

[0013] Preferably, the carbohydrate supplement includes glucose and fructose.

[0014] Preferably, the carbohydrate supplement is glucose and fructose. According to the mass percentage of the aerosol type flower nutrition spray, the glucose is 1-3% and the fructose is 1-3%.

[0015] The present application uses glucose and fructose as the sugar nutrition required by flowers, because glucose is a monosaccharide that can be directly absorbed and utilized by flowers without conversion, and can quickly provide energy for flowers. It has a positive effect on the growth and development of flowers, helps to maintain the vividness of flowers and prolong the flowering period. The sweetness of glucose is relatively low, and it will not attract too many insects, reducing the risk of flowers being attacked by pests. Fructose is more soluble in water and is more easily absorbed by flowers. Fructose has a certain moisturizing effect, which can keep flowers moist and prevent them from withering.

[0016] Preferably, the growth regulators include 6-benzylaminopurine, gibberellin, and methyl naphthylacetate.

[0017] Preferably, the growth regulator is 6-benzylaminopurine, gibberellin, and methyl naphthylacetate. According to the mass percentage of the aerosol type flower nutrition spray, 6-benzylaminopurine is 0.02-0.04%, gibberellin is 0.02-0.04%, and methyl naphthylacetate is 0.01-0.03%.

[0018] By adopting the above technical scheme, 6-benzylaminopurine, gibberellin and methyl naphthylacetate are selected as plant growth regulators. 6-benzylaminopurine, as a widely used cytokinin, can promote cell division and expansion, can stimulate the growth and development of fresh flowers, make flowers fuller and brighter, delay the aging process of fresh flowers, and prolong the flowering period. Cytokinin can inhibit the synthesis of ethylene, reduce the aging and falling of flowers, enhance the stress resistance of fresh flowers, and improve the adaptability to adverse environments. Gibberellin promotes the growth and elongation of fresh flowers, especially for some flowers with shorter stems, can increase their height and ornamental value. It can break the dormant state of fresh flowers, promote the opening of flowers, and can enhance the preservation effect when used in conjunction with other growth regulators. Methyl naphthylacetate is a commonly used abscisic acid inhibitor, and abscisic acid is a hormone that promotes plant aging and shedding. The use of abscisic acid inhibitors can delay the aging and falling of fresh flowers, and can effectively inhibit the aging of fresh flowers.

[0019] Preferably, the fungicide includes 8-hydroxyquinoline citrate and sodium benzoate.

[0020] By adopting the above technical scheme, 8-hydroxyquinoline citrate and sodium benzoate are selected as bactericides. 8-hydroxyquinoline salts are a broad-spectrum bactericide that can combine with metal ions to take away the iron ions and copper ions in bacteria, so that the bacteria cannot grow and reproduce normally due to the lack of necessary metal ions, thereby achieving the purpose of sterilization. Ethylene is a plant hormone that promotes the aging of flowers. 8-hydroxyquinoline salts can inhibit the production of ethylene, thereby delaying the aging process of flowers and extending the life of flowers. Sodium benzoate is a common food preservative and can also be used as a bactericide in flower nutrients. It has a certain inhibitory effect on bacteria, yeasts and molds.

[0021] Preferably, the osmotic agent comprises glycerol.

[0022] Glycerin has a strong water absorption capacity and can form a moist environment around flowers, reduce the evaporation of water in flowers, keep flowers fresh and plump, help maintain the turgor pressure of flower cells, and prevent flowers from wilting due to water loss. Glycerin can also form a protective film on the surface of flowers to reduce the damage to flowers from the external environment, such as dust and pollutants. It has a certain softening effect on the petals and leaves of flowers, making them smoother and more shiny. It also has the effect of regulating osmotic pressure and improving cell membrane permeability. Studies have shown that an appropriate amount of glycerin can increase the permeability of cell membranes by 20%-30%, thereby improving the efficiency of flowers in absorbing nutrients.

[0023] Preferably, the trace element supplement includes a mixture of one or more of calcium chloride, magnesium sulfate, and ferrous sulfate.

[0024] The trace elements required by flowers are Ca 2+ Mg 2+ , Fe 2+ The specific substances selected in this application are calcium chloride, magnesium sulfate and ferrous sulfite. 2+ It helps maintain the stability of the cell walls of flowers, strengthens the strength of flowers and stems, and reduces the occurrence of wilting flowers and bending stems. It can also combine with organic acids to reduce the damage of acidity to flowers and adjust the pH of the nutrient solution. 2+ Magnesium is an important component of chlorophyll. Adding magnesium can promote photosynthesis in the leaves of flowers, provide more energy for flowers, and make flowers more colorful. It also helps maintain the ion balance in flower cells and ensure the normal physiological metabolism of flowers. 2+ It is an element necessary for the synthesis of chlorophyll. Lack of iron will cause the leaves of flowers to turn yellow and affect photosynthesis. Adding an appropriate amount of ferrous iron can prevent and improve the symptoms of iron deficiency, keep flowers green and vibrant, participate in the redox reaction in flowers, and play an important role in the respiration and energy metabolism of flowers.

[0025] Preferably, the preservative comprises salicylic acid.

[0026] Salicylic acid is used to promote the growth and preservation of fresh flowers. It can stimulate the growth of the root system of flowers and improve the ability of flowers to absorb nutrients.

[0027] Preferably, the pH adjuster includes VC.

[0028] VC is selected as the pH regulator. VC is not only an organic acid, but also has strong antioxidant properties. It can remove free radicals produced by flowers during metabolism, reduce oxidative damage, help maintain the color and shape of flowers, prevent flowers from fading and deformation, and extend the life of flowers. At the same time, it prevents the ferrous ions in the formula from being oxidized during the stirring process or the flowers absorbing nutrients.

[0029] Preferably, the propellant includes carbon dioxide, which, as a propellant, is also beneficial to promoting photosynthesis of plants.

[0030] In a second aspect, the present application provides a method for preparing an aerosol-type flower nutrition spray, using the following technical solution: A method for preparing an aerosol-type flower nutrient spray comprises the following steps: Step 1: Prepare plant fermentation liquid: Step 1a: Wash, mix and crush shiitake mushrooms, cactus and mint to obtain a plant mixture; Step 1b: mixing the plant mixture with water to obtain a plant solution; Step 1c: adding 0.05-0.1 g / L of Bacillus licheniformis and 0.01-0.05 g / L of Acetobacter xylinum into the plant liquid, and fermenting at 38-42° C. for 5-10 days to obtain a crude fermentation liquid; Step 1d: centrifuging and taking the supernatant of the crude fermentation liquid to obtain the plant fermentation liquid; Step 2: Mix the solvent, the sugar supplement, the bactericide, the penetrant, the preservative, and the plant fermentation liquid, and stir evenly to obtain a solution A; Step 3: Add a pH adjuster to solution A and stir evenly to obtain solution B; Step 4: Add growth regulators and trace element supplements to solution B, stir evenly, and obtain nutrients; Step 5: Fill the nutrient component and the propellant into the aerosol container to obtain the aerosol type flower nutrient spray.

[0031] By adopting the above technical solution, plant fermentation liquid is prepared under specific conditions, and mixed evenly with other raw materials in a specific order to obtain an aerosol type flower nutrition spray. The raw materials can have a more adequate coordination effect, so that the flowers can more fully absorb the aerosol type flower nutrition spray, utilize the nutrition therein, and improve the growth of the flowers.

[0032] Preferably, the mass ratio of the plant mixture to water is 1:(3-5).

[0033] In summary, this application has the following beneficial effects: 1. Compared with liquid nutrients, the aerosol nutrient spray of the present application simplifies the use process. Users only need to press the nozzle to evenly spray on the flowers and leaves of the plant without complicated preparation, which improves the convenience of use. In addition, it can be quickly absorbed directly through the stomata of the leaves, providing timely and effective nutrient supply for flowers that are in urgent need of nutrition.

[0034] 2. In the present application, mushrooms, cacti and mint with a special ratio are preferably used to prepare plant fermentation liquid. Through mixed fermentation, the natural microorganisms in these raw materials and the added fermentation agent together form a complex microbial community. The community can decompose and transform the organic matter in the raw materials to generate metabolites such as amino acids, organic acids, enzymes and vitamins that are beneficial to the growth of flowers. These products work synergistically in the fermentation liquid to promote the growth and development of flowers, especially the growth of the root system, making it stronger, thereby improving the water and nutrient absorption capacity of flowers, accelerating the growth rate and enhancing stress resistance.

[0035] 3. The nutrient spray contains plant fermentation liquid made from mushrooms, cacti, and mint. When sprayed, part of it will penetrate into the soil. The organic acids and enzymes in it help the soil form a granular structure, improve air permeability, and promote root respiration and nutrient absorption of flowers. In addition, the fermentation liquid directly provides nutrients to the roots, promotes root growth and increases root hairs, thereby enhancing the root system's ability to absorb water and nutrients.

[0075] Table 1 Comparative Example Comparative Example 1 An aerosol-type flower nutrition spray, which is different from Example 1 in that Tremella fuciformis is used instead of shiitake mushrooms in the fermentation raw material of the plant fermentation liquid.

[0076] Comparative Example 2 An aerosol-type flower nutrition spray, which is different from Example 1 in that aloe vera is used instead of cactus in the fermentation raw material of the plant fermentation liquid.

[0077] Comparative Example 3 An aerosol-type flower nutrition spray, which is different from Example 1 in that pepper is used instead of mint in the fermentation raw material of the plant fermentation liquid.

[0078] Comparative Example 4 An aerosol-type flower nutrition spray is different from Example 1 in that the plant fermentation liquid is omitted and a solvent is used to supplement its original content.

[0079] Performance testing The aerosol-type flower nutrient sprays of Examples 1-4 and Comparative Examples 1-4 were used to culture peonies, and the initial number of peonies cultured with each aerosol-type flower nutrient spray was 100. The survival rate and the number of flower branches of each grade of peonies were recorded in Table 2.

[0080] The evaluation criteria for the number of flower branches of each grade of peony refer to NY / T 953-2006 "Cut Peony Flowers".

[0081] The culture conditions are as follows: Temperature: The optimum growth temperature is 20℃-25℃, and the air humidity is maintained at 60%-80%. In the initial stage of cultivation (about 7 days), the temperature is 10-15℃ during the day and 5-10℃ at night; in the early stage (about 10 days), the temperature is 17℃-20℃ during the day and 10℃-15℃ at night; in the middle stage, the temperature is 18℃-20℃ during the day and 10℃-12℃ at night; in the late stage (after flowering), the temperature is 20℃-25℃ during the day and 14℃-18℃ at night. The light duration is 10-12h, and the light intensity is controlled at 3000-50000lux.

[0082] Lighting: The lighting time is 10-12 hours. When the light intensity is lower than 3000 lux, start supplementary lighting. When it is higher than 50000 lux, cover the shade net.

[0083] Frequency and concentration of aerosol flower nutrient spray: Fertilize once after germination, and once every 15 days from the germination period to the budding period, for a total of 2 times; water with aerosol flower nutrient spray once every 7 days during the budding period, and temporarily stop fertilizing after the buds show color; continue to fertilize after flowering, once every 15-20 days; the amount of fertilizer is 10 sprays / plant each time.

[0084] Table 2 According to the test data in Table 2, the survival rates of the flowers in Examples 1-4 are higher than that in Comparative Example 4, and the flower branches of the flowers in Examples 1-4 at level 1 and level 2 are much higher than that in Comparative Example 4. This indicates that the aerosol flower nutrient spray containing plant fermentation liquid provided in the present application does have a positive promoting effect on the growth of flowers.

[0085] Comparative Examples 1-3 are based on Example 1, and any of the fermentation raw materials in the plant fermentation liquid is replaced with other raw materials. The corresponding aerosol-type flower nutrition spray has a survival rate of only about 90%; the number of peony in level 1 is greatly reduced compared with Example 1, and the number of levels 2 and 3 is significantly increased. It shows that after any of the fermentation raw materials in the plant fermentation liquid are replaced with other raw materials, the special combination effect of mushrooms, cactus, and mint in the fermentation is destroyed, so that the active ingredients cannot fully play a significant effect on the growth of flowers.

[0086] Example 4 is based on Example 1, but the selection of carbohydrate supplement, bactericide and growth regulator is changed. Compared with Comparative Example 4, Example 4 still has obvious advantages. Compared with Example 1, the survival rate of Example 4 is slightly decreased, and the number of peony in level 1 is also slightly decreased, but the number of level 3 is not significantly increased. It shows that in addition to plant fermentation liquid, if the composition and dosage of other raw materials can be further limited, the positive promotion effect of plant fermentation liquid and nutrient spray on flowers can be better promoted.

[0087] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
