Description

Technical Field

[0001] This application relates to the field of camellia cultivation, and more specifically, to a method for regulating the flowering quality of abundant-flowering camellias. Background Technology

[0002] Camellia is a general term for ornamental varieties of the genus Camellia in the family Theaceae, and it is a world-renowned woody ornamental flower. Floribunda camellias, as a type of camellia characterized by abundant flowering, are highly favored in the market due to their large number of flowers and high ornamental value.

[0003] However, in commercial container seedling production, the quality of flowering plants is often unstable, which is manifested in the small number of flower buds per plant and the general uniformity of flowering, which seriously affects their ornamental effect and economic value as commercial potted plants.

[0004] Current camellia cultivation techniques mostly focus on controlling the flowering period through complex methods, rather than improving the quality of flowering. When existing methods for controlling the flowering period are applied to container-grown floribunda camellias, they are difficult to effectively increase the number of flower buds and the uniformity of flowering, thus limiting the improvement of their commercial value. Summary of the Invention

[0005] The purpose of this application is to provide a method for regulating the flowering quality of abundant-flowering camellias. By spraying a new shoot inducer and combining it with a growth-promoting nutrient supply during the vegetative growth period, and applying a flowering inducer and a flower bud growth agent and combining it with a flower-promoting nutrient supply during the reproductive growth period, the number of flower buds per plant of container-grown abundant-flowering camellias is significantly increased, while the development of flower buds tends to be more uniform.

[0012] Optionally, before operating during the reproductive growth period of the camellia floribunda, the control method includes: planting the camellia floribunda in a container using a cultivation substrate to obtain the camellia floribunda container seedlings; wherein the cultivation substrate comprises 50% imported peat moss, 30% perlite, 10% akadama soil and 10% kanuma soil, or 60% imported peat moss and 40% medium-particle perlite.

[0013] Optionally, during the application of the new shoot inducer, the growth-promoting nutrient supply agent, the flowering inducer, the bud growth agent, and the flowering-promoting nutrient supply agent: the container seedlings are placed in a well-ventilated, semi-shaded environment and watered according to the principle of watering only when the soil is dry.

[0014] Optionally, during the vegetative growth period of the camellia, the new shoot inducer and the growth-promoting nutrient supply agent are sprayed simultaneously on a cycle of 25 to 35 days, and repeated 3 times.

[0015] Optionally, during the reproductive growth period of the camellia floribunda, the flowering inducer is sprayed and the flowering-promoting nutrient supply is applied simultaneously, with a cycle of 25 to 35 days, and this is repeated twice; 55 to 65 days after spraying the flowering inducer and applying the flowering-promoting nutrient supply simultaneously, the bud growth agent is sprayed and the flowering-promoting nutrient supply is applied simultaneously, with a cycle of 25 to 35 days, and this is repeated three times.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0025] Abundant-flowered camellias mainly refer to camellias that bloom profusely (generally, the number of flower buds on the terminal bud or leaf bud is more than 3). They mainly include wild resources of the Camellia genus such as the Camellia floridae section and the Camellia pubescens section, as well as the densely budded varieties in the Camellia floridae group and other variety groups.

[0026] Currently, most existing camellia cultivation techniques focus on controlling the flowering period through complex methods, such as three stages: low-temperature refrigeration, seedling establishment, and flower-inducing treatment. These methods involve the application of specific microbial fertilizers and ethephon fumigation, resulting in a complicated process with high environmental control requirements. Another method relies on the preparation of complex special nutrient solutions to extend the flowering period, which involves complex preparation processes and high implementation costs.

[0027] However, the above methods were not proposed to improve flowering quality. When existing flowering period control methods are directly applied to container seedlings of abundant-flowering camellias, it is difficult to effectively increase the number of flower buds and improve flowering uniformity, which restricts the improvement of their commercial value.

[0028] Based on this, this application proposes a method for regulating the flowering quality of Camellia floribunda. This method uses a specific concentration of exogenous 6-benzylaminopurine combined with a growth-promoting nutrient supply to increase the number of new shoots of Camellia floribunda. Then, a specific concentration of chlormequat chloride is used as a flowering inducer, gibberellin is used as a flower bud growth agent, and combined with a flowering-promoting nutrient supply for staged treatment. This effectively promotes the differentiation and development of flower buds in container Camellia floribunda seedlings during the flower bud differentiation period, significantly increases the number of flower buds per plant in container Camellia floribunda seedlings, and improves the uniformity of flowering.

[0029] Please refer to the following: Figure 1 , Figure 1 This application provides a flowchart for regulating the flowering quality of abundant-flowering camellias according to an embodiment of the present application; the present application provides a method for regulating the flowering quality of abundant-flowering camellias, which includes the following steps:

[0030] Preparation and cultivation basics of container seedlings

[0031] To achieve stable and controllable control effects, container cultivation is preferred. Before the control operation, floribunda camellias are planted in containers using a suitable cultivation substrate to obtain robust and uniformly sized container-grown floribunda camellia seedlings.

[0032] In an optional embodiment, the cultivation substrate is formulated as follows: 60% imported peat moss (fiber coarseness 10-30mm) + 40% medium-particle perlite. In this ratio, the coarse-fiber peat moss provides excellent structural support and water retention; its specific fiber coarseness maintains both substrate porosity and suitable moisture retention. The medium-particle perlite effectively enhances the substrate's aeration and drainage, preventing waterlogging and root rot. Together, they create a balanced root growth environment, providing a stable attachment medium for the floribunda camellia roots while ensuring effective supply and storage of water and nutrients, and preventing substrate compaction, thus laying a solid foundation for robust plant growth.

[0033] In an optional embodiment, the cultivation substrate may also be composed of a mixture of 50% imported peat moss, 30% perlite, 10% akadama soil, and 10% kanuma soil. This formula, while maintaining the peat moss framework, incorporates akadama soil, which possesses excellent granular structure and ion exchange capacity, providing a stable supply of minerals such as potassium and calcium. Kanuma soil, with its porous characteristics and stable pH value, further optimizes the substrate's aeration and nutrient retention. The scientific ratio of these four materials forms a more complete substrate system, maintaining a suitable pore configuration in its physical structure and providing a more balanced nutrient supply and pH buffering capacity in its chemical properties. This promotes root development while significantly enhancing the plant's resistance to abiotic stresses.

[0034] Step S100: Spray the container seedlings of Camellia floribunda in the vegetative growth stage with a new shoot inducer and apply a growth-promoting nutrient supply agent.

[0035] Spraying of shoot inducing agents and application of growth-promoting nutrient supplies

[0036] During the vegetative growth period of Camellia floribunda, before the flower bud differentiation period, spray new shoot inducers and apply growth-promoting nutrient supply agents simultaneously.

[0037] In this embodiment, the shoot inducer is an exogenous 6-benzylaminopurine solution of 200 mg / L to 250 mg / L. When spraying, the solution is evenly sprayed on the stems and both sides of the leaves until the stems are moist and water droplets drip from the leaf tips, thereby ensuring that the agent is effectively absorbed.

[0038] The preferred shoot growth regulator is a growth-promoting nutrient supply agent with a nitrogen, phosphorus, and potassium ratio of 30:10:10. The application concentration is 350 to 450 times dilution, i.e., 2-3g diluted in 1 liter of irrigation water for watering. This helps increase the number of new shoots, providing support for subsequent reproductive growth and the production of more flower buds. Preferably, the application concentration is 400 times dilution, i.e., 2.5g diluted in 1 liter of irrigation water for watering.

[0039] In this embodiment, the above operations need to be repeated every 25 to 35 days during the vegetative growth period, preferably every 30 days. Depending on the plant growth and climate conditions, 2 to 3 consecutive treatments (preferably 3) are usually sufficient to achieve significant results. Throughout the treatment period, the container seedlings should be placed in a well-ventilated, semi-shaded environment, avoiding direct sunlight and strong sunlight, and watering should be strictly carried out according to the principle of watering only when the soil is dry to maintain the optimal physiological state of the plants.

[0040] Step S200: Simultaneously spray the entire plant of the container-grown Camellia floribunda in its reproductive growth stage with a flowering inducer and a flower bud growth agent until the plant stems are moist and water droplets drip from the leaf tips; and apply a flowering-promoting nutrient supply agent to the container-grown Camellia floribunda.

[0041] Spraying of flowering inducers

[0042] After the floribunda camellia enters the early stage of flower bud differentiation, the first foliar spraying of the entire plant is carried out. The flowering inducer is an exogenous chlormequat chloride solution with a concentration of 1500 mg / L to 2500 mg / L. Preferably, an exogenous chlormequat chloride solution with a concentration of 2000 mg / L is selected. During spraying, the solution is evenly sprayed onto the stems and both sides of the leaves until the stems are moistened and water droplets drip from the leaf tips, thus ensuring effective absorption of the agent.

[0043] In this embodiment, the above operations need to be repeated every 25 to 35 days during the reproductive growth period, preferably every 30 days. Depending on the plant growth and climate conditions, significant results can usually be achieved by treating 2 to 3 times (preferably 2 times).

[0044] It should be noted that the morphological criteria for the beginning stage of the reproductive growth period in the embodiments of this application are: the current year's branches of the plant have lignified, and the terminal buds and leaf buds are plump; in terms of time, it is generally from the end of May to the beginning of June each year.

[0045] Chlormequat chloride, as a plant growth retardant, can effectively inhibit vegetative growth and promote the distribution of photosynthetic products to flower buds, making it a core substance for increasing the number of flower buds.

[0046] In an optional embodiment, to further improve the adhesion of the pesticide solution to the leaf surface and the absorption efficiency of the active ingredient, Tween 20 (polyoxyethylene sorbitan laurate) at a volume concentration of 0.1% to 0.3% can be added simultaneously as a nonionic surfactant when preparing a 1500 mg / L to 2500 mg / L chlormequat chloride solution; preferably, a volume concentration of 0.2% Tween 20 is selected. This additive can significantly reduce the surface tension of the pesticide solution, enhance its wetting and spreading ability on waxy leaf surfaces, effectively prevent the pesticide solution from agglomerating and rolling off, thereby increasing the contact area and action time between the agent and the leaf cuticle. At the same time, Tween 20 can also promote the penetration of chlormequat chloride molecules through the leaf epidermal barrier by changing cell membrane permeability, improve the bioavailability of the active ingredient, and ultimately achieve a more stable and efficient growth regulation effect.

[0047] Spraying of flower bud growth agent

[0048] The first foliar spray should be applied 55 to 65 days after the initial application of the flowering inducer. The bud growth regulator is an exogenous gibberellin solution with a concentration of 200 mg / L to 250 mg / L. Preferably, an exogenous gibberellin solution with a concentration of 200 mg / L is used.

[0049] After spraying the flowering inducer for 55 to 65 days, the bud growth agent is sprayed every 25 to 35 days, and this process is repeated 3 times; preferably, the flowering inducer is sprayed every 30 days after 60 days.

[0050] Gibberellins are generally considered to be growth-promoting hormones. They can also affect the development and opening process of flower buds. Appropriate amounts of gibberellins can promote the development of flower buds or synchronize flowering.

[0051] Administration of nutritional supplements

[0052] While spraying flowering inducers and bud growth agents, apply flowering-promoting nutrient supply agents.

[0053] For flower-promoting nutrient supplies, the preferred N:P:K ratio is 10:30:20. The application concentration is 350 to 450 times dilution, and the application rate is 5 to 15 mL per liter of cultivation substrate.

[0054] It should be noted that the N, P, and K ratios in the embodiments of this application are determined based on the nutritional requirements of container-grown Camellia floribunda: high nitrogen is required during the vegetative growth stage to promote new shoot germination; high phosphorus and potassium are required during the reproductive growth stage to promote flower bud differentiation. The preferred ratios described in this application should not be construed as limiting adjustments to equivalent ratios within the scope of this application.

[0055] In this embodiment, the above operations need to be repeated every 25 to 35 days during the reproductive growth period, preferably every 30 days. During the application of the flowering inducer and bud growth agent, 4 to 5 consecutive treatments (preferably 5) are usually sufficient to achieve significant results. Throughout the treatment period, the container seedlings should be placed in a well-ventilated, semi-shaded environment, avoiding direct western exposure and strong sunlight, and watering should be strictly performed according to the principle of watering only when the soil is dry to the touch, in order to maintain the optimal physiological state of the plants.

[0056] Effect verification

[0057] Example 1:

[0058] Taking the Floribunda Camellia cultivar 'Liexiang' as an example, the potting substrate is 60% imported peat moss (fiber coarseness 10-30mm) + 40% perlite, and the container used is a 5-gallon plastic pot.

[0059] 1.1 Implementation Method

[0060] When the plants enter the reproductive growth stage, different hormones and concentrations are applied according to Table 1 (Table 1 shows the types and concentrations of hormones provided in the embodiments of this application). Thereafter, the above treatment is repeated every 30 days, for a total of 3 times. During the treatment period, all plants are placed in a well-ventilated, semi-shaded environment, and water is managed according to the principle of "watering when dry."

[0061]

[0062] At the start of the experiment, three current-year lignified branches of similar length and position were randomly selected from each plant and marked. The number of internodes on each branch was recorded. Every 30 days, the number of terminal buds and axillary buds on each branch were counted and calculated using the formula: The average number of axillary buds on each branch was calculated.

[0063] 1.2 Implementation Results

[0064] The number of terminal flower buds and lateral buds, as well as the number of lateral buds and flower buds, of 'Liexiang' under different treatments were analyzed (please refer to Table 2, which shows the effect of different hormone treatments on the number of 'Liexiang' flower buds provided in the embodiments of this application). Figure 2 The results of different treatments on the number of flower buds show that, overall, compared to the control group (CK), the E3 (2000 mg / L CCC) treatment, while having a moderate effect on increasing the number of terminal buds, significantly increased the number of axillary buds. The number of axillary buds and the average number of axillary buds were significantly higher than the control group (CK) and other treatments. Please refer to the relevant documentation for further information. Figure 2 , Figure 2 This is a comparison chart showing the effect of different hormone treatments on the number of 'Liexiang' flower buds, provided in the embodiments of this application; by Figure 2It can be clearly seen that the spraying treatment with 2000 mg / L CCC can significantly increase the number of axillary buds of 'Liexiang'.

[0065] Example 2:

[0066] Taking the Floribunda camellia variety 'Fragrance of the Ancient Capital' as an example, the potting substrate is 60% imported peat moss (fiber coarseness 10-30mm) + 40% perlite, and the container used is a 3-gallon plastic pot.

[0067] 2.1 Implementation Method

[0068] The implementation method is the same as that in 1.1 of Example 1.

[0069] 2.2 Implementation Results

[0070] For 'Fragrance of the Ancient Capital', please refer to Table 3 and... Figure 3 Table 3 is a comparison table of the effects of different hormone treatments on the number of flower buds of 'Fragrance of the Ancient Capital' provided in the embodiments of this application; Figure 3 This is a comparison chart of the effect of different hormone treatments on the number of flower buds of 'Fragrance of the Ancient Capital' provided in the embodiments of this application; as shown in Table 3 and Figure 3 It can be seen that the number of terminal buds in E3 was significantly higher than that in CK and other treatments, while the number of axillary buds was not significantly different from that in E2, but significantly different from that in E1 and CK. Furthermore, there was no significant difference between E2 and CK. The average number of axillary buds was also increased and significantly higher than that in E1. Chlormequat chloride can significantly increase the number of buds.

[0071]

[0072] Example 3:

[0073] Taking the Floribunda Camellia cultivar 'Liexiang' as an example, we compared the effects of bud growth promoters on bud development.

[0074] 3.1 Implementation Method

[0075] When the plants enter the reproductive growth stage, spray the entire plant with 200 mg / L gibberellin. Repeat this treatment every 30 days for a total of four times. During the treatment period, all plants should be placed in a well-ventilated, shaded area, and water should be managed according to the principle of "watering only when the soil is dry to the touch."

[0076] 3.2 Implementation Results

[0077] Combined with Table 4, Figure 4 As can be seen, Table 4 is a comparative table of the effects of gibberellin treatment on the size of 'Liexiang' flower buds; Figure 4This document presents a comparison of 'Liexiang' flower buds treated with different gibberellin concentrations according to embodiments of this application. Non-parametric tests on the flower bud diameters of the gibberellin-treated and control groups show a highly significant difference. Gibberellin treatment significantly accelerates flower bud development, causing buds to rapidly enlarge and develop color. Furthermore, Table 4 shows a smaller standard deviation in flower bud diameter data and relatively better flowering uniformity. Figure 3 The effects of gibberellin can also be seen visually.

[0078]

[0079] Example 4:

[0080] Taking the floribunda camellia variety 'Meiyu' as an example, the effects of different shoot inducers on shoot germination were investigated.

[0081] 4.1 Implementation Method

[0082] This embodiment provides a method for regulating the flowering quality of container-grown Camellia floribunda using exogenous hormones. Container-grown Camellia floribunda 'Meiyu' was cultivated using a mixture of 50% imported peat moss (fiber thickness 10-30mm), 30% perlite, 10% Akadama soil, and 10% Kanuma soil. The first exogenous 6-BA spray was applied at the early stage of flower bud differentiation (Table 5). 0.05% Tween20 was added as a surfactant to the treatment solution. The treatment method involved spraying the entire plant, ensuring the stems, both sides of the leaves, and the buds were completely moistened, with liquid dripping from the leaf tips. A second spray was applied after 30 days. The container-grown Camellia floribunda was then placed in a well-ventilated, semi-shaded nursery.

[0083]

[0084] Six plants were used for each treatment. At the beginning of the experiment, five current-year shoots were selected from each plant and marked. The growth of the current-year shoots was counted and measured with a ruler. The current-year shoot growth rate (%) = (length at the end of the experiment - length at the beginning of the experiment) / length at the beginning of the experiment. The number of leaf buds that sprouted from the selected current-year shoots on each plant in each treatment was counted.

[0085] 4.2 Implementation Results

[0086] A comparative analysis of the growth rates of current-year shoots of 'Meiyu' under different treatments (see Table 6, which shows the effect of exogenous 6-BA on the vegetative growth of new current-year shoots provided in the embodiments of this application) revealed that E3 (6-BA 200 mg / L) significantly increased the growth rate of current-year shoots compared to CK and other treatments. Although the number of new shoots in E3 was similar to that in E1 and E2, it was significantly higher than that in CK. Considering the growth rate of current-year shoots, the 200 mg / L 6-BA treatment was the most effective in increasing the number and length of new shoots and promoting vegetative growth in 'Meiyu'.

[0087]

[0088] Example 5:

[0089] Taking the floribunda camellia variety 'Liexiang' as an example, this study compares the effects of different flower-promoting nutrient supply agents on flower formation.

[0090] 5.1 Implementation Plan

[0091] The experimental material was a potted camellia variety named 'Liexiang'. The planting substrate consisted of 60% imported peat moss (fiber coarseness 10-30mm) + 40% perlite, and the container used was a 5-gallon pot.

[0092] When the plants entered the early stage of flower bud differentiation, the first treatment was performed (see Table 7, which is a comparison table of different water-soluble fertilizer treatments provided in the embodiments of this application). Thereafter, the above synergistic treatment was repeated every 30 days, for a total of 4 times. During the treatment period, all plants were placed in a ventilated shaded area, and water was managed according to the principle of "watering when dry."

[0093] At the start of the experiment, three current-year lignified branches of similar length and position were randomly selected from each plant and marked, and the number of internodes of each branch was recorded. For vegetative growth, the number of new shoots, the number of new shoot leaves, and the length of new shoots were statistically analyzed every 30 days. For reproductive growth, the number of terminal buds and axillary buds of each branch were statistically analyzed every 30 days.

[0094] 5.2 Implementation Results

[0095] Table 8 (Table 8 is a comparison table of the effects of different fertilizer treatments provided in the embodiments of this application on the number of flower buds of 'Liexiang' camellia) shows that there is no significant difference in the number of terminal buds of F1 compared with F2 and CK, but the number of axillary buds and the average number of leaf axillary buds are significantly higher than those of the other two. The results show that the water-soluble fertilizer with N:P:K=10:30:20 can provide sufficient nutrition for camellia 'Liexiang', thereby significantly promoting the formation of axillary buds.

[0096] In summary, the present invention provides a method for regulating the flowering quality of abundant-flowering camellias. By applying specific flowering inducers (chlormequat chloride), bud growth promoters (gibberellins), and nutrient suppliers (high-phosphorus and potassium water-soluble fertilizer) in stages during the critical period of reproductive growth, and supplementing with suitable cultivation substrates and environmental management, stable and significant effects can be obtained through simple operation. This method can effectively enhance the commercial value and ornamental value of abundant-flowering camellias and is suitable for large-scale promotion and application in containerized production.

[0097] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
