Description

Technical Field

[0001] The invention belongs to the technical field of plant growth regulation, and particularly relates to a growth regulator for European hybrid hazelnut, and a preparation method and application thereof. Background Art

[0003] Plant growth regulators can regulate crop growth and development, modulate the yield formation process, and improve crop yield and quality. Paclobutrazol (PP333) and uniconazole (S3307) are triazole chemical control agents, classified as plant growth retardants. They regulate crop growth and development by reducing endogenous gibberellins in plants, enhancing crop resistance and ultimately improving quality and yield. Sodium nitrophenolate (CSN) is a synthetic plant growth regulator that rapidly penetrates plants, relieving cell dormancy, promoting growth and development, and accelerating plant growth, thereby increasing yield. However, when paclobutrazol, uniconazole, or sodium nitrophenolate alone, or a mixture of two or three of these substances, is applied to the European-American hybrid hazelnut, the photosynthetic efficiency of the hazelnut leaves is low, and the chlorophyll content, nut quality, and yield of the hazelnuts need to be further improved. Summary of the Invention

[0010] As a preferred embodiment, the triazole chemical control agent is selected from paclobutrazol, uniconazole, tebuconazole or propiconazole.

[0011] As a preferred embodiment, the soluble K + The salt is potassium chloride, potassium nitrate, potassium sulfate or potassium carbonate.

[0012] The second object of the present invention is a method for preparing a growth regulator for European hybrid hazelnut, comprising the following steps: Weigh the efficacy component and synergistic component according to the concentration of each component.

[0014] The potassium salt solution is added to the efficacy component, mixed at room temperature, and then the glycerol-3-phosphate solution is added and mixed at 25° C. to 35° C. to obtain a growth regulator for European hybrid hazelnut.

[0015] As a preferred embodiment, in the growth regulator, the concentration of triazole chemical control agent is 108mg / L~120mg / L, the concentration of sodium nitrophenolate is 2.6mg / L~3.1mg / L, the concentration of glycerol-3-phosphate is 0.03mmol / L~0.06mmol / L, and the concentration of soluble K + The salt concentration is 1.0mol / L~2.0mol / L.

The specific mechanism of action is:

[0018] The present invention firstly combines a triazole chemical control agent and sodium nitrophenolate. On the one hand, the triazole chemical control agent reduces the endogenous gibberellin content of the hazel tree and slows down the growth rate of the plant.

The above-mentioned functional components maintain the growth and development of the European hybrid hazel in a balanced state, ensuring that the growth focus of the hazel tree is transferred from the elongation of the stem to the growth and development of the leaves. The functional components composed of the triazole chemical control agent and sodium nitrophenolate are mixed with soluble K + The salt compounding increases the stomatal conductance of hazel leaves, improves the intercellular carbon dioxide content and the carbon fixation efficiency of the leaves. Due to the shift of the growth center, more nitrogen is concentrated in the leaves, thereby improving the net photosynthetic efficiency of the leaves. In addition, the efficacy component composed of the above-mentioned triazole chemical control agent and sodium nitrophenolate is combined with soluble K + The addition of glycerol-3-phosphate to the compound system of salt increases the content of photosynthetic pigments in hazel leaves and the conversion efficiency of primary light energy of photosystem II (PSII), thereby increasing the chlorophyll content of hazel leaves. + The synergistic components of salt and glycerol-3-phosphate greatly improve the photosynthesis efficiency and chlorophyll content in hazelnut leaves. In addition, the growth regulator provided by the present invention not only controls the growth of hazelnuts but also achieves the accumulation of nutrients, thereby effectively improving the quality and yield of hazelnuts.

[0024] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific examples and experimental data, but the examples are not intended to limit the present invention.

[0025] The background of the present invention mentions existing plant growth regulators, such as paclobutrazol, uniconazole, and sodium nitrophenolate. However, when paclobutrazol, uniconazole, sodium nitrophenolate, or a mixture of two or three of these substances are applied to the European-American hybrid hazelnut, the photosynthetic efficiency of the hazelnut leaves is low, and the chlorophyll content of the leaves, hazelnut quality, and yield need to be further improved. Based on the technical problems encountered in the cultivation of the European-American hybrid hazelnut, the present invention provides a growth regulator for the European-American hybrid hazelnut, a preparation method, and applications thereof.

[0026] The technical contents of the present invention are described in detail below.

[0027] Experimental part Trial Location: The trial will be conducted in 2023 at the Liaodong University Large Hazelnut Demonstration Orchard in Loufang Town, Zhen'an District, Dandong City, Liaoning Province. Dandong, where the Large Hazelnut Demonstration Orchard is located, has a warm temperate humid monsoon climate with distinct four seasons and abundant rainfall. The average annual temperature is around 9°C, with 2300-2530 hours of sunshine per year and an average annual precipitation of 800-1200 mm.

[0028] Test materials: European hybrid hazelnut "Liaozhen No. 2", the field trial was conducted from May 2023 to November 2023. Seven-year-old European hybrid hazelnut trees were selected, and their growth, soil and climate conditions, terrain conditions, field water and fertilizer management, and field pest control were roughly the same. The planting spacing was 3 meters. The test plant growth regulators were 15% paclobutrazol wettable powder, 5% uniclobutrazol wettable powder, and 1.4% sodium nitrophenolate soluble solution produced by Sichuan Guoguang Agrochemical Co., Ltd. Glycerol-3-phosphate and soluble K + Salts (potassium chloride, potassium nitrate, potassium sulfate, potassium carbonate) were all commercially available.

[0029] The present invention provides a growth regulator for European hybrid hazelnut, which is prepared from an efficacy component and a synergistic component. The efficacy component is a triazole chemical control agent and sodium nitrophenolate, and the synergistic component is glycerol-3-phosphate and soluble K + Salt.

[0030] Among the growth regulators, the concentration of triazole chemical control agents is 80mg / L~150mg / L, the concentration of sodium nitrophenolate is 2.25mg / L~3.6mg / L, the concentration of glycerol-3-phosphate is 0.01mmol / L~0.08mmol / L, and the concentration of soluble K + The salt concentration is 0.2mol / L~2.6mol / L.

[0031] In the above technical solution, triazole chemical control agents and sodium nitrophenolate are used as the effective components to maintain the growth and development of European hybrid hazelnuts in a balanced state, ensuring that the growth focus of the hazelnuts is transferred from the elongation of the stems to the growth and development of the leaves; the effective components composed of triazole chemical control agents and sodium nitrophenolate are combined with soluble K + The salt compounding increases the stomatal conductance of hazel leaves, improves the intercellular carbon dioxide content and the carbon fixation efficiency of the leaves. Due to the shift of the growth center, more nitrogen is concentrated in the leaves, thereby improving the net photosynthetic efficiency of the leaves. In addition, the efficacy component composed of the above-mentioned triazole chemical control agent and sodium nitrophenolate is combined with soluble K + The addition of glycerol-3-phosphate to the compound system of salt increases the content of photosynthetic pigments in hazel leaves and the conversion efficiency of primary light energy of photosystem II (PSII), thereby increasing the chlorophyll content of hazel leaves. + The synergistic components of salt and glycerol-3-phosphate greatly improve the photosynthesis efficiency and chlorophyll content in hazelnut leaves. In addition, the growth regulator provided by the present invention not only controls the growth of hazelnuts but also achieves the accumulation of nutrients, thereby effectively improving the quality and yield of hazelnuts.

[0032] Regarding the concentrations of the above-mentioned active ingredients, the concentrations of triazole chemical control agents and sodium nitrophenolate must be strictly matched, otherwise the hazel tree cannot achieve a balanced growth state, and the appropriate amount of nutrients cannot be transferred to the leaves, which will have a significant impact on the chlorophyll content of the leaves and the quality and yield of hazelnuts. When the concentration of the triazole chemical control agent is 80 mg / L and the concentration of sodium nitrophenolate is less than 2.25 mg / L, the triazole chemical control agent has a significant effect, exerting a strong growth inhibition state. The overall growth and development of the hazel tree is greatly slowed down, and the growth of the hazel tree rhizomes and leaves is in a slow state. When the concentration of the triazole chemical control agent is 80 mg / L and the concentration of sodium nitrophenolate is greater than 3.6 mg / L, the sodium nitrophenolate has a significant effect, resulting in an increase in the growth rate of the hazel tree rhizomes, and the leaves do not accumulate more nitrogen, thus affecting the chlorophyll content of the hazel leaves.

[0033] To further slow the growth of hazel trees and transfer nutrients to their leaves, thereby promoting chlorophyll synthesis, the concentration of the triazole chemical control agent is 100 mg / L to 130 mg / L, and the concentration of sodium nitrophenolate is 2.5 mg / L to 3.2 mg / L. More preferably, the concentration of the triazole chemical control agent is 120 mg / L, and the concentration of sodium nitrophenolate is 3.0 mg / L.

[0034] In order to further improve the quality and yield of hazelnuts, the present invention limits the concentration of glycerol-3-phosphate to 0.03 mmol / L to 0.06 mmol / L. More preferably, the concentration of glycerol-3-phosphate is 0.05 mmol / L.

[0035] In order to further increase the chlorophyll content of hazelnut leaves, the soluble K + The concentration of the salt is 1.0 mol / L to 2.0 mol / L. More preferably, the soluble K + The salt concentration is 1.6 mol / L.

[0036] It should be noted that the triazole chemical control agent used in the present invention is selected from paclobutrazol, uniconazole, tebuconazole or propiconazole. + The salt is potassium chloride, potassium nitrate, potassium sulfate or potassium carbonate.

The testing process is as follows, and the test results are shown in Tables 1 to 4.

[0069] 1. Measurement items and methods 1.1 Chlorophyll content determination Chlorophyll content was measured once every 7 days after each application using a SPAD-502 Plus chlorophyll meter. The measurements were conducted on May 20, June 3, and June 17. A healthy, fully grown leaf was selected from each tree in each of the four directions.

A large number of studies have shown that plant growth regulators promote the growth and development of crops by regulating the physiological processes in plants, thereby increasing yield. As can be seen from Tables 2 and 3, after using the growth regulator for European hybrid hazelnuts provided by the present invention, the hazelnut yield and quality of the European hybrid hazelnut "Liaozhen No. 2" are significantly improved. The growth regulator for European hybrid hazelnuts provided by the present invention has triazole chemical control agents and sodium nitrophenolate as effective components, glycerol-3-phosphate and soluble K + Salt has a better synergistic effect as a synergistic component. Comparative Example 6 in Tables 2 and 3 above is a blank control group. Compared with Example 1, Comparative Examples 1 to 5 respectively adjust the components or dosage of the growth regulator of Example 1. Comparative Example 5 uses only the efficacy component. Comparative Example 1 and Comparative Example 2 remove glycerol-3-phosphate and KCl from the synergistic components. By comparing the data of Example 1, Comparative Example 1, Comparative Example 2 and Comparative Example 5 in Tables 2 and 3, it can be seen that for the total yield of hazelnuts, after adopting the growth regulator provided by Example 1 (680.5 kg / mu), the total yield of hazelnuts is significantly improved. On the basis of Comparative Example 5, the increase in the total yield of hazelnuts in Example 1 is not the sum of the increase in the yield of Comparative Example 1 and Comparative Example 2. The yield of Example 1 far exceeds that of Comparative Example 1 (648.3 kg / mu) and Comparative Example 2 (657.6 kg / mu). The quality of hazelnuts after adopting the growth regulator provided by the present invention has also been significantly improved. In summary, the growth regulator of the present invention is a compound comprising triazole chemical control agents and sodium nitrophenolate, glycerol-3-phosphate and soluble K + Salt has a positive effect on the yield and quality of hazelnuts, glycerol-3-phosphate and soluble K + Salt has a good synergistic effect on improving hazelnut yield and quality.

[0079] 6. The effects of different plant growth regulators on the growth of new shoots are shown in Table 4.

[0080] Table 4 Effects of different plant growth regulators on new shoot growth Plant growth regulator has remarkable effect in the management of young shoots of fruit trees, can control new shoot growth, adjust tree shape, promote lateral branch germination, and lay a solid foundation for the high yield and high quality of fruit trees. After adopting the growth regulator for flat European hybrid hazelnut provided by the present invention, the new shoot management effect of flat European hybrid hazelnut " Liao Zhen No. 2 " is remarkable, effectively regulated plant growth, suppress plant vegetative growth, promote reproductive growth, prevent plant from occurring vigorous growth and excessive growth, played the effect of regulating and controlling crop new shoot growth, shortening internodes, dwarfing plants, with very good control length and yield-increasing effect. Comparative Example 6 in above-mentioned Table 4 is blank control group, compared with blank control group, after adopting the growth regulator of Comparative Example 1 ~ Comparative Example 5, all suppressed the new slightly growth of hazelnut to varying degrees, shortened bud spacing, but after adopting the growth regulator of embodiment 1, the new shoot growth inhibitory effect of hazelnut is the most obvious, and its bud spacing is also the shortest. In summary, the present invention adds glycerol-3-phosphate and KCl as synergistic component to the control vigorous yield-increasing effect of hazelnut tree in growth regulator.

[0081] In summary, the sensitivity of European and American hybrid hazelnuts to the growth regulators provided in the examples of the present invention and the comparative examples is different. Spraying the growth regulators can effectively improve the phenomenon of new shoot elongation, promote leaf photosynthesis, increase hazelnut yield, and improve fruit quality. + Salt is a synergistic component that significantly increases the chlorophyll content of hazelnut leaves, fruit quality and yield, effectively reduces the length of new shoots and shortens the distance between buds.

[0082] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
