Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to a plant growth regulating nutrient solution made from pure traditional Chinese medicine and its preparation method. Background Technology

[0002] Plant growth regulators are an indispensable input in modern agricultural production. They can promote root development, improve nutrient absorption, and increase crop yield and quality by regulating the growth and metabolic processes within plants. With the rapid growth in consumer demand for pollution-free vegetables and fruits, the market's requirements for the safety of plant growth regulator products have also increased significantly. Against this backdrop, developing a plant growth regulator nutrient solution that is naturally derived, free of chemical residues, and possesses multiple agronomic benefits has become a pressing issue in the agricultural sector.

[0003] Currently, there are some organic nutrient solution products on the market made from plant extracts, humic acid, or seaweed extracts. Some research is also exploring the introduction of active ingredients from traditional Chinese medicine into agricultural applications, utilizing the polysaccharides, flavonoids, saponins, and other bioactive substances they contain to regulate plant growth and development. These explorations have accumulated experience for the development of naturally derived plant growth regulators and have verified the feasibility of applying active ingredients from traditional Chinese medicine in the agricultural field.

[0004] However, existing technologies still exhibit significant problems in practical applications. On the one hand, current plant-derived nutrient solutions generally have limited functions, primarily focusing on supplementing mineral nutrients or promoting root growth. Few products can simultaneously achieve multiple effects such as promoting strong root growth and seedling development, improving soil compaction and acidification, and enhancing fruit sugar content and taste. Farmers often need to combine multiple products in practice, increasing costs and causing inconvenience. On the other hand, the value of traditional Chinese medicine lies not only in a single component but also in the synergistic effects of multiple herbs when rationally combined. Existing products lack systematic formulations of multiple herbs and comprehensive decoction processes, resulting in insufficient variety of active substances and inadequate synergistic effects among components. Ultimately, this leads to unstable product efficacy and limited actual yield and quality improvement. Therefore, it is necessary to provide a plant growth regulating nutrient solution prepared from scientifically formulated multiple herbs using a systematic decoction process to fundamentally solve the aforementioned problems.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0006] To address the problems in related technologies, this invention proposes a plant growth regulating nutrient solution made from pure traditional Chinese medicine and its preparation method, in order to overcome the aforementioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by the present invention is as follows: According to one aspect of the present invention, a plant growth regulating nutrient solution prepared from pure traditional Chinese medicine is provided. The plant growth regulating nutrient solution prepared from pure traditional Chinese medicine comprises a growth-promoting component and a conditioning component. The growth-promoting component comprises Astragalus membranaceus, Atractylodes macrocephala, and Angelica sinensis. The conditioning component comprises Sophora flavescens, Citrus reticulata peel, Crataegus pinnatifida, Hordeum vulgare malt, and Glycyrrhiza uralensis. The plant growth regulating nutrient solution prepared from pure traditional Chinese medicine is prepared by decocting the growth-promoting component and the conditioning component in groups, filtering, combining the filtrates, and concentrating under reduced pressure.

[0008] Furthermore, the growth-promoting components include the following ingredients in parts by weight: Astragalus membranaceus 15-25 parts, Atractylodes macrocephala 6-15 parts, Angelica sinensis 4-10 parts; the conditioning components include the following ingredients in parts by weight: Sophora flavescens 6-12 parts, Citrus reticulata 5-10 parts, Crataegus pinnatifida 8-15 parts, Hordeum vulgare 8-15 parts, Glycyrrhiza uralensis 3-8 parts.

[0009] Furthermore, the weight ratio of the growth-promoting component to the conditioning component is 1:0.6 to 1:2.4; the growth-promoting component and the conditioning component are combined after being extracted by decoction in groups.

[0010] Further, the grouped decoction includes: mixing the growth-promoting components and soaking them in water at 8-12 times their total weight, followed by decoction extraction to obtain a growth-promoting extract; mixing the conditioning components and soaking them in water at 8-12 times their total weight, followed by decoction extraction to obtain a conditioning extract.

[0011] Furthermore, both the growth-promoting and conditioning extracts were obtained through at least two water decoction extractions; the combined filtrate consisted of: the growth-promoting and conditioning extracts were combined and then allowed to settle and filtered to obtain a mixed extract; the mixed extract was concentrated under reduced pressure to obtain a plant growth regulating nutrient solution made from pure traditional Chinese medicine.

[0012] Furthermore, all filtration processes are performed using 80-120 mesh filters; the pH value of the plant growth regulating nutrient solution, prepared from pure Chinese herbal medicine, is 4.5-6.5, and it is a uniform brown liquid.

[0013] Furthermore, the vacuum concentration process includes heating and concentrating the mixed extract under negative pressure using a vacuum vacuum concentration tank; the plant growth regulator nutrient solution made from pure Chinese herbal medicine contains no chemically synthesized plant growth regulators, no inorganic fertilizer additives, and no chemically synthesized preservatives.

[0014] According to another aspect of the present invention, a method for preparing a plant growth regulating nutrient solution made from pure traditional Chinese medicine is also provided. This method includes: weighing astragalus, atractylodes macrocephala, angelica sinensis, sophora flavescens, tangerine peel, hawthorn, malt, and licorice root by weight, and washing and draining them separately; mixing astragalus, atractylodes macrocephala, and angelica sinensis, adding 8-12 times their total weight of water and soaking for 0.5-1.5 hours, followed by a first decoction for 1-2 hours, and filtering to obtain a first filtrate; adding 6-10 times their total weight of water to the residue for a second decoction for 0.5-1 hour. The first filtrate is obtained by filtration. The following steps are performed: Sophora flavescens, Citrus reticulata peel, Crataegus pinnatifida, Malt, and Glycyrrhiza uralensis are mixed and soaked in 8-12 times their total weight of water for 0.5-1.5 hours, followed by a third decoction for 1-2 hours. The third filtrate is obtained by filtration. The residue is then boiled in 6-10 times their total weight of water for a fourth decoction for 0.5-1 hour. The fourth filtrate is obtained by filtration. The first, second, third, and fourth filtrates are combined, allowed to settle, and then filtered to obtain a mixed extract. The mixed extract is concentrated under reduced pressure at 60-80℃ to obtain a pure herbal plant growth regulator nutrient solution.

[0015] Furthermore, the decoction temperature for the first, second, third, and fourth decoctions is 90-100℃; the plant growth regulating nutrient solution made from pure Chinese herbal medicine after decompression concentration is cooled at room temperature and bottled for storage.

[0016] Furthermore, the plant growth regulator nutrient solution, made from pure Chinese herbal decoction, can be diluted 100-300 times and used for root irrigation, applying 100-500 mL per plant each time, once every 7-15 days, for 2-4 consecutive applications; and / or diluted 200-500 times and used for foliar spraying, once every 7-10 days, for 2-3 consecutive applications.

[0017] The beneficial effects of this invention are as follows: (1) This invention uses eight Chinese medicinal herbs, namely Astragalus membranaceus, Atractylodes macrocephala, Angelica sinensis, Sophora flavescens, Citrus reticulata, Crataegus pinnatifida, Hordeum vulgare, and Glycyrrhiza uralensis, as raw materials. Through scientific formulation of Chinese medicinal herbs, the growth-promoting components and conditioning components are organically combined. This can simultaneously achieve multiple agronomic effects such as promoting crop root growth and seedling development, improving soil compaction and acidification, and enhancing the sugar content and taste of fruits. This effectively solves the problem that existing plant-derived nutrient solution products have single functions and farmers need to use multiple products together.

[0018] (2) The present invention adopts a systematic preparation process of decocting growth-promoting and conditioning components in groups, extracting them separately, and then concentrating them together. This process fully leverages the independent extraction advantages of each component during the group decoction process, while retaining the synergistic effect between the active substances after consolidation, making the product richer in active substances and more stable in efficacy.

[0019] (3) The nutrient solution obtained by the present invention is filtered through 80-120 mesh and concentrated under reduced pressure. The product is a brownish-brown homogeneous liquid with a pH value of 4.5-6.5. It has stable physicochemical properties and is suitable for both root irrigation and foliar spraying. It is flexible to use and easy to operate.

[0020] (4) The present invention uses only Chinese medicinal materials and water as raw materials throughout the process. It does not contain chemically synthesized plant growth regulators, inorganic fertilizer additives and chemically synthesized preservatives. The product is non-toxic, harmless and has no chemical residues. It fully meets the requirements of zero chemical input for pollution-free vegetable and fruit production and is an ideal choice for green organic agricultural production.

[0021] (5) The preparation process of this invention adopts the traditional water decoction combined with modern vacuum concentration technology. The process route is clear, the equipment requirements are simple, the operating conditions are mild, and it is suitable for large-scale production. It has good prospects for industrial promotion and application. Attached Figure Description

Example

[0034] In this embodiment, a plant growth regulating nutrient solution made from pure traditional Chinese medicine was prepared. The raw materials were weighed according to the above-mentioned preferred formula, including 20g of Astragalus membranaceus, 12g of Atractylodes macrocephala, 7g of Angelica sinensis, 9g of Sophora flavescens, 7g of Citrus reticulata peel, 11g of Crataegus pinnatifida, 11g of Hordeum vulgare malt, and 5g of Glycyrrhiza uralensis. First, Astragalus membranaceus, Atractylodes macrocephala, and Angelica sinensis were mixed and soaked in approximately 390mL of water (10 times their total weight) for 1 hour. The mixture was then decocted for 1.5 hours at 95°C, and the first filtrate was obtained by filtration. Next, approximately 310mL of water (8 times their total weight) was added to the residue, and the mixture was decocted for 45 minutes at 95°C, and the second filtrate was obtained by filtration. Separately, a mixture of Sophora flavescens, Citrus reticulata peel, Crataegus pinnatifida, Malt, and Glycyrrhiza uralensis was added and soaked in approximately 430 mL of water (10 times their total weight) for 1 hour. The mixture was then decocted for a third time at 95°C for 1.5 hours, and filtered to obtain the third filtrate. Next, approximately 340 mL of water (8 times their total weight) was added to the residue, and the mixture was decocted for a fourth time at 95°C for 45 minutes, and filtered to obtain the fourth filtrate. The four filtrates were combined, allowed to settle for 2 hours, and then filtered through a 100-mesh sieve. The solution was then concentrated under reduced pressure in a vacuum concentrator at 70°C until the relative density at 25°C was 1.05 to 1.1. After cooling to room temperature, the solution was bottled, yielding a homogeneous brown liquid with a pH of 5.3. This is the plant growth regulating nutrient solution prepared from pure traditional Chinese medicine according to this invention, designated as sample S1.

[0035] Comparative Example 1 In this comparative example, a nutrient solution with the same formula was prepared by co-decoction. This was to investigate the effect of the grouped decoction process on the product's efficacy. Using the same raw material composition and ratio as in Example 1, 20g of Astragalus membranaceus, 12g of Atractylodes macrocephala, 7g of Angelica sinensis, 9g of Sophora flavescens, 7g of Citrus reticulata peel, 11g of Crataegus pinnatifida, 11g of Hordeum vulgare malt, and 5g of Glycyrrhiza uralensis were weighed. These eight herbs were mixed together and soaked in approximately 820mL of water (10 times their total weight) for 1 hour. The mixture was then decocted at 95°C for 1.5 hours, and filtered to obtain the first filtrate. Next, approximately 650mL of water (8 times their total weight) was added to the residue, and the mixture was decocted again at 95°C for 45 minutes, and filtered to obtain the second filtrate. The two filtrates were combined, allowed to settle for 2 hours, filtered through a 100-mesh sieve, and concentrated under reduced pressure at 70°C until the relative density at 25°C was 1.05 to 1.10. After cooling to room temperature, the mixture was bottled to obtain comparative sample C1.

[0036] Comparative Example 2 In this comparative example, a nutrient solution containing only the growth-promoting components was prepared to investigate the effect of the overall formulation on rooting and seedling strengthening. 20g of Astragalus membranaceus, 12g of Atractylodes macrocephala, and 7g of Angelica sinensis were weighed. The three herbs were mixed and soaked in approximately 390mL of water (10 times their total weight) for 1 hour. The mixture was then decocted at 95℃ for 1.5 hours and filtered to obtain the first filtrate. Next, approximately 310mL of water (8 times their total weight) was added to the residue and decocted again at 95℃ for 45 minutes, followed by filtration to obtain the second filtrate. The two filtrates were combined, allowed to settle for 2 hours, filtered through a 100-mesh sieve, and concentrated under reduced pressure at 70℃ until the relative density at 25℃ was 1.05 to 1.10. The concentrate was then cooled and bottled to obtain comparative sample C2.

[0037] Comparative Example 3 In this comparative example, a nutrient solution containing only the conditioning and compatibility components was prepared to investigate the effect of the overall compatibility on improving soil planting conditions and enhancing fruit quality. 9g of Sophora flavescens, 7g of Citrus reticulata peel, 11g of Crataegus pinnatifida, 11g of Hordeum vulgare malt, and 5g of Glycyrrhiza uralensis were weighed. The five herbs were mixed and soaked in approximately 430mL of water (10 times their total weight) for 1 hour. The mixture was then decocted at 95℃ for 1.5 hours and filtered to obtain the first filtrate. Next, approximately 340mL of water (8 times their total weight) was added to the residue and decocted again at 95℃ for 45 minutes, followed by filtration to obtain the second filtrate. The two filtrates were combined, allowed to settle for 2 hours, and then filtered through a 100-mesh sieve. The solution was then concentrated under reduced pressure at 70℃ until the relative density at 25℃ was 1.05 to 1.10. After cooling and bottling, the comparative sample C3 was obtained. Example

[0038] In this embodiment, the effect of different dilution ratios on promoting root growth and seedling vigor was verified. Tomato seedlings of uniform growth (Jinpeng No. 1 variety, 25 days old) were selected as the test material, totaling 120 seedlings, which were randomly divided into 4 groups, with 3 replicates per group and 10 seedlings per replicate. The blank control group was irrigated with an equal volume of water, while the other three groups were treated with root irrigation after diluting sample S1 by 100, 200, and 300 times, respectively. Each seedling in each treatment group was irrigated with 200 mL of the solution every 10 days for 3 consecutive applications, while other cultivation and management conditions remained consistent. On day 15 after the last application, 5 seedlings from each replicate were randomly selected to measure plant height, stem diameter, total root length, and fresh root weight. The results were statistically analyzed and are shown in Table 1.

[0039] Table 1 - Effects of the nutrient solution of the present invention on the rooting and seedling vigor development of tomato seedlings at different dilution ratios Group Plant height (cm) Stem diameter (mm) Total root length (cm) Fresh weight of roots (g) Blank control group 28.3 5.1 186.4 3.2 Low-dilution group (100x) 34.7 6.3 267.8 4.8 Medium dilution group (200x) 32.5 5.9 248.3 4.5 High-dilution group (300 times) 30.8 5.5 218.6 3.9 As shown in Table 1, compared with the blank control group, the nutrient solution of the present invention can promote the growth of tomato seedlings and root development at different dilution ratios. The root irrigation treatment with a 100-fold dilution showed the most significant effect, indicating that the nutrient solution of the present invention has a significant effect on promoting crop rooting and seedling growth. It also confirms that the root irrigation treatment with a 100-fold dilution is the preferred method for subsequent rooting and seedling growth experiments. Example

[0040] In this embodiment, the effect of promoting root growth and strengthening seedlings was compared and verified. Specifically, to further verify the effectiveness of the grouped decoction process and overall compatibility of the present invention, 120 tomato seedlings of uniform growth (Jinpeng No. 1 variety, 25 days old) were selected and randomly divided into 4 groups, with 3 replicates per group and 10 seedlings per replicate. The blank control group was irrigated with an equal amount of water. Comparative Example 1 was treated with a 100-fold dilution of C1, Comparative Example 2 with a 100-fold dilution of C2, and the example group with a 100-fold dilution of S1. Each seedling in each group was irrigated with 200 mL of water every 10 days for 3 consecutive applications, while other management conditions remained consistent. On day 15 after the last application, plant height, stem diameter, and fresh weight per plant were measured in each group. The results are shown in Table 2.

[0041] Table 2 - Effects of different samples on growth indicators of tomato seedlings Group Average plant height (cm) Average stem diameter (mm) Average fresh root weight (g / plant) C0 28.3 5.1 3.2 C1 31.2 5.6 3.9 C2 32.8 5.9 4.3 S1 34.7 6.3 4.8 like Figure 2 As shown in the figure, the horizontal axis represents the treatment groups, C0 represents the blank control group, C1 represents the comparative group obtained by decocting the same raw materials together, C2 represents the comparative group obtained by containing only the growth-promoting components, and S1 represents the treatment group of the plant growth regulating nutrient solution prepared by decocting pure traditional Chinese medicine as described in Example 1 of this invention; the vertical axis represents the measured values. The three curves in the figure represent the average plant height, average stem diameter, and average root fresh weight, respectively. Figure 2 As can be seen, compared with the blank control group and the comparative group, the nutrient solution treatment group of the present invention showed better results in terms of average plant height, average stem diameter and average root fresh weight, indicating that the nutrient solution of the present invention has a better promoting effect on crop rooting and seedling growth.

[0042] Combine Table 2 and Figure 2 It can be seen that, compared with the blank control group C0, the average plant height, average stem diameter, and average root fresh weight of Comparative Example 1 (C1), Comparative Example 2 (C2), and Example 3 (S1) were all increased, with Example 3 (S1) showing the greatest increase. This indicates that, based on the same raw materials, using growth-promoting and conditioning components separately decocted, extracted, and then combined and concentrated, can achieve better growth-promoting and seedling-strengthening effects; it also shows that the overall combination of the eight Chinese herbal medicines has a better comprehensive promoting effect than Comparative Example 2, which only contains growth-promoting components. Example

[0043] In this embodiment, the effect of improving planting conditions in acidified and compacted soil was verified. Soil from greenhouse vegetables grown continuously for three years was selected as the test soil. The initial soil pH was 5.1, and the soil bulk density was 1.38 g / cm³. 3 The soil showed significant acidification and compaction. The tested soil was placed into uniform planting pots, 10 kg per pot, and planted with one uniformly growing tomato seedling. The experiment consisted of four groups, with three replicates per group. The control group was irrigated with an equal volume of water. Comparative Example 1 was treated with a 150-fold dilution of C1, Comparative Example 3 with a 150-fold dilution of C3, and the Example Group with a 150-fold dilution of S1. Each treatment group received 500 mL of water per pot per application, once every 10 days for four consecutive applications, with all other management conditions remaining consistent. Rhizosphere soil samples were collected 20 days after the last application to determine soil pH, soil bulk density, and the content of water-stable aggregates larger than 0.25 mm. The results are shown in Table 3.

[0044] Table 3 - Effects of different samples on soil physicochemical properties Group Soil pH <![CDATA[Soil bulk density (g / cm 3 )]]> Content of water-stable aggregates >0.25mm (%) Blank control group 5.1 1.38 46.2 Comparative Example 1 (C1) 5.3 1.35 49.1 Comparative Example 3 (C3) 5.4 1.33 51 Example group (S1) 5.5 1.30 54.8 As shown in Table 3, the soil pH value of the S1 treatment group was higher than that of the blank control group, the soil bulk density was lower, and the content of water-stable aggregates was higher, indicating that the nutrient solution of the present invention has a positive effect on improving the planting conditions of acidified and compacted soils. At the same time, the improvement effect of the S1 treatment group was better than that of Comparative Examples 1 and 3, indicating that simply changing the decoction method or simply using conditioning components is difficult to achieve the comprehensive effect of the nutrient solution of the present invention. The overall compatibility and decoction process adopted in the present invention can better improve the physical and chemical properties of the soil and create a more suitable soil environment for crop root growth. Example

[0045] In this embodiment, the effect of improving fruit quality was verified. Strawberry plants of uniform growth (Hongyan variety) were selected as test materials, and the treatment period was the initial flowering stage. A total of 120 plants were randomly divided into 4 groups, with 3 replicates per group and 10 plants per replicate. The blank control group was sprayed with an equal volume of water, comparative example group 1 was sprayed with a 300-fold diluted C1 solution, comparative example group 3 was sprayed with a 300-fold diluted C3 solution, and the example group was sprayed with a 300-fold diluted S1 solution. Each group was sprayed once every 8 days for 3 consecutive times, with all other management conditions remaining consistent. After the fruit matured, 10 fruits were randomly harvested from each replicate, and the soluble solids content, titratable acid content, and sugar-acid ratio were measured. Sensory evaluation was also conducted by evaluators, and the results are shown in Table 4.

[0046] Table 4 - Effects of different samples on strawberry fruit quality indicators Group Soluble solids content (°Brix) Titratable acid content (%) Sugar-acid ratio Group C0 9.2 0.78 11.8 C0 C1 10.3 0.72 14.3 C1 C3 10.8 0.69 15.7 C3 S1 11.8 0.63 18.7 S1 like Figure 3As shown in the figure, the horizontal axis represents the treatment groups, C0 represents the blank control group, C1 represents the comparative group obtained by decocting the same raw materials together, C3 represents the comparative group obtained by containing only the conditioning and compatibility components, and S1 represents the treatment group of the plant growth regulating nutrient solution prepared by decocting pure traditional Chinese medicine obtained in Example 1 of this invention; the vertical axis represents the measured values; the three curves in the figure represent the soluble solids content (°Brix), titratable acid content (%), and sugar-acid ratio, respectively. Figure 3 As can be seen, compared with the blank control group and the comparative group, the nutrient solution treatment group of the present invention can increase the soluble solids content and sugar-acid ratio of the fruit and reduce the titratable acid content, indicating that the nutrient solution of the present invention has a better effect on improving fruit quality.

[0047] Combine Table 4 and Figure 3 It can be seen that, compared with the blank control group C0, comparative example group 1 C1, comparative example group 3 C3, and example group S1 can all increase the soluble solids content of strawberry fruits and improve the sugar-acid ratio, while reducing the titratable acid content. Among them, example group S1 has the most significant overall effect. This indicates that the nutrient solution of the present invention has good application value in improving fruit quality, and its effect is better than the same formula mixed decoction scheme and the scheme containing only conditioning components.

[0048] It should be noted that, based on the experimental results of Examples 2 to 5, the plant growth regulating nutrient solution prepared from pure traditional Chinese medicine according to the present invention can significantly promote plant growth and root development during the seedling stage, improve soil physicochemical indicators under acidified and compacted soil conditions, and increase soluble solids content and improve sugar-acid ratio during the fruit quality formation stage, demonstrating good comprehensive agronomic application effects. Compared with the comparative examples of mixed decoctions with the same formula and single functional component comparisons, sample S1 of the present invention performs better in multiple indicators, indicating that the present invention, through the rational combination of growth-promoting and conditioning components, combined with the process design of group decoction, separate extraction, and subsequent concentration, can effectively improve the comprehensive use effect of the product, thereby solving the problem of existing plant-derived nutrient solution products having single functions and requiring the combined use of multiple products.

[0049] like Figure 1As shown, according to another embodiment of the present invention, a method for preparing a plant growth regulating nutrient solution made from pure traditional Chinese medicine decoction is also provided.
