Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural biotechnology, specifically to a composition for promoting the expansion of lily buds, its preparation method, and its application. Background Technology
[0002] Lilies are among the world's most famous cut and potted flowers, beloved by consumers for their beautiful shapes, rich colors, and auspicious symbolism. In cut lily production, the size of the flower bud is a key indicator of its commercial grade and market price. Lily cut flowers with full, large buds have greater ornamental value and stronger market competitiveness. Therefore, effectively promoting the expansion of lily buds is a crucial technical aspect of the lily industry.
[0003] In production practice, optimizing water and fertilizer management (especially increasing the application of phosphorus and potassium fertilizers) and ensuring sufficient sunlight can provide ample nutrition for flower bud development, thereby promoting bud enlargement. However, these methods have limited effectiveness and are easily constrained by factors such as climate conditions and cultivation facilities, making it difficult to consistently and significantly improve flower bud size. In addition, gibberellins, cytokinins, or auxins are sometimes applied alone in production, but the effects of using a single plant growth regulator are limited and unstable, and can easily lead to problems such as excessive vegetative growth, weak flower stalks, and abnormal development. Often, this approach is counterproductive, severely affecting other key commercial traits such as plant shape and flower stalk hardness while promoting flower bud enlargement.
[0004] Currently, there is a lack of plant growth regulators specifically designed for lily bud enlargement on the market. Therefore, there is an urgent need in this field to develop a new, highly efficient, and safe plant growth regulator that can promote cell division and enlargement of lily buds while avoiding adverse side effects such as excessive plant growth and lateral bud sprouting, thereby significantly enhancing the commercial value and market competitiveness of cut lilies. Summary of the Invention
[0005] The purpose of this invention is to provide a composition for promoting the expansion of lily flower buds, its preparation method, and its application. The composition includes a compound fungicide of gibberellin, indole-3-acetic acid, fluopyram, and pyraclostrobin, as well as a water-soluble fertilizer containing amino acids. Spraying this mixture during the lily budding stage can synergistically promote bud cell division and expansion, increasing bud size while maintaining plant vigor.
[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:
[0007] A composition for promoting the expansion of lily buds, comprising, by weight: 90-110 parts gibberellin, 1-3 parts indole-3-acetic acid, 0.5-1 parts a fungicide including fluopyram and pyraclostrobin, and 1-2 parts a water-soluble fertilizer containing amino acids.
[0008] Furthermore, the gibberellin is gibberellin GA3.
[0009] Furthermore, the free amino acid content in the amino acid-containing water-soluble fertilizer is not less than 100 g / L.
[0010] On the other hand, the present invention provides a method for preparing the above composition, comprising the following steps:
[0011] S1: Provides gibberellin solution, indole-3-acetic acid solution, fungicides including fluopyram and pyraclostrobin, and water-soluble fertilizer containing amino acids;
[0012] S2: Mix the components provided in step S1 with water, and adjust the pH of the resulting mixture to 5.8~6.2 to obtain an applicable working solution.
[0013] Furthermore, the concentration of the gibberellin mother liquor is 1 g / L, and it is prepared by fully dissolving the gibberellin powder in 95% ethanol and then adding water.
[0014] Furthermore, the concentration of the indole-3-acetic acid mother liquor is 1 g / L, which is prepared by fully dissolving the indole-3-acetic acid powder in 95% ethanol and then adding water.
[0015] Furthermore, the active ingredients of fungicides including fluopyram and pyraclostrobin include fluopyram and pyraclostrobin, with a total active ingredient content of ≥ 42%.
[0016] Furthermore, the amino acid-containing water-soluble fertilizer contains ≥ 100 g / L of free amino acids and ≥ 20 g / L of trace elements.
[0017] Furthermore, the volume ratio of the gibberellin solution, indole-3-acetic acid solution, fungicide including fluopyram and pyraclostrobin, amino acid-containing water-soluble fertilizer to water is (90-110):(1-3):(0.5-1):(1-2):(884-907.5).
[0018] On the other hand, the present invention proposes a method for promoting the expansion of lily buds by applying an effective amount of the above-mentioned composition or the working solution prepared according to the above method to the buds during the budding stage of the lily plant.
[0019] Furthermore, the application is by spraying, and the number of sprays is 1 to 3.
[0020] On the other hand, the present invention proposes the use of the above composition in the preparation of an agent for promoting the expansion of lily buds.
[0021] Furthermore, the formulation is used to spray the buds of lilies during the budding stage.
[0022] The beneficial effects of this invention are:
[0023] In the composition of this invention, gibberellin and indole-3-acetic acid are compounded in a specific mass ratio of 90-110:1-3, solving the problem of the one-sided and unstable effects of single plant growth regulators. Low concentrations of indole-3-acetic acid directionally promote cell division in the meristematic tissue of flower buds, providing a sufficient cellular basis for bud expansion; simultaneously, high concentrations of gibberellin strongly drive the longitudinal elongation and volume expansion of these cells. At this ratio, the two produce a synergistic effect, thereby simultaneously promoting the three-dimensional expansion of flower buds through both cell number and cell volume. As shown in the example data, the treated flower buds exhibit significant and balanced growth in both length and circumference, effectively improving the commercial specifications of cut flowers.
[0024] The composition of this invention, by introducing a compound fungicide of fluopyram and pyraclostrobin, along with an amino acid-containing water-soluble fertilizer, effectively ensures the overall health and marketability of the plant while promoting flower bud development. The addition of the fungicide not only prevents key diseases during the budding stage, but its active ingredient, pyraclostrobin, also enhances plant vitality through its plant health-promoting effects, helping to counteract the tissue weakness that gibberellin may cause, thereby maintaining the firmness and uprightness of the flower stalk. The amino acid-containing water-soluble fertilizer provides an easily absorbed organic nitrogen source and trace elements, timely replenishing the nutrients consumed by the rapid expansion of flower buds and preventing nutrient deficiency and premature aging caused by excessive reproductive growth. While significantly increasing flower bud size, it avoids adverse side effects such as excessive vegetative growth and softening of flower stalks, achieving simultaneous optimization of the target traits and overall agronomic traits.
[0025] This invention integrates plant growth regulation, disease prevention, and nutrient supplementation into a single working solution. By adjusting the pH to 5.8-6.2, the stability and compatibility of each component under application conditions are ensured. Producers only need to spray this working solution 1-3 times during the lily budding stage to simultaneously achieve multiple management objectives. This greatly simplifies the operation process, reduces the risk of phytotoxicity and efficacy fluctuations caused by multiple preparations or improper mixing, and standardizes and repeats the technical step of promoting flower bud enlargement, making it particularly suitable for large-scale, intensive production.
[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
