Description

Technical Field

[0001] The invention relates to the technical field of fertilizers, and in particular to a fertilizer composition and application thereof in preparing a water-soluble fertilizer. Background Art

[0002] In the field of modern agriculture, especially in the precision cultivation of Chinese medicinal materials, the scientific selection and precise application of fertilizers are of vital importance to ensure crop yields, improve quality, and maintain the long-term sustainability of the soil environment. Although traditional fertilizers have historically provided the necessary nutritional support for crops, they have many limitations in terms of the balance of nutrient release, utilization efficiency, and environmental friendliness. In particular, in the cultivation of root plants such as angelica that have special requirements for soil nutrients and growth conditions, the limitations of traditional fertilizers are particularly prominent, and it is difficult to meet the dual needs of modern Chinese medicinal material cultivation for high efficiency and environmental protection.

[0003] In recent years, with the in-depth exploration of the comprehensive development and utilization of traditional Chinese medicine resources, the secondary utilization value of traditional Chinese medicine waste such as Ling Gui Shu Gan Tang residue has gradually attracted widespread attention from the scientific research community. Ling Gui Shu Gan Tang is a classic prescription in clinical Chinese medicine. The residue produced after decoction contains rich organic matter, trace elements and a variety of biologically active substances, which have potential to promote plant growth. However, how to convert these traditional Chinese medicine wastes into efficient and environmentally friendly fertilizers through scientific methods and accurately apply them to the cultivation practice of traditional Chinese medicines is still a technical problem that needs to be overcome.

[0004] At the same time, natural plant extracts are increasingly used in the agricultural field due to their unique biological activity and environmental friendliness. The organic combination of traditional Chinese medicine waste and natural plant extracts to develop new, efficient and environmentally friendly fertilizer compositions has become a major research hotspot in the current agricultural scientific research field. However, although many fertilizer products have emerged on the market, there have been no reports of fertilizer products designed for root plants such as angelica that can give full play to the synergistic effects of traditional Chinese medicine waste and natural plant extracts. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a fertilizer composition and application thereof in preparing water-soluble fertilizer.

[0010] Furthermore, the preparation method of the fertilizer composition includes the following steps:

[0011] Mix and pulverize the medicinal residues of Linggui Zhugan Decoction and Rabdosia lanceolata to obtain a first mixture;

[0012] Perform oxygen-rich microwave plasma treatment on the first mixture to obtain a second mixture;

[0013] Decoct the second mixture, and then filter, concentrate, and dry it to obtain an extract;

[0014] Add the extract to the glycerol and grind to obtain the fertilizer composition.

[0015] Furthermore, the working condition parameters of the oxygen-rich microwave plasma treatment include: using oxygen and argon with a volume ratio of 7:1 as the working medium, the microwave power is 280 - 400 W, and after treating for 60 - 90 seconds in the glow discharge mode, continue to introduce oxygen for 5 - 10 minutes.

[0016] Furthermore, the working condition parameters of the decoction include: the number of decoction times is 1 - 3 times, and the decoction time is 60 - 120 minutes; the working condition parameters of the grinding include: the grinding speed is 1500 - 2000 rpm, and the grinding time is 5 - 10 minutes.

[0017] In a second aspect, the present invention provides the application of the fertilizer composition according to any one of the first aspect in the preparation of water-soluble fertilizers.

[0018] In a third aspect, the present invention provides a water-soluble fertilizer, which includes the fertilizer composition according to any one of the first aspect and a basal fertilizer, and the basal fertilizer includes at least one of a water-soluble substance containing nitrogen, a water-soluble substance containing potassium, and a water-soluble substance containing phosphorus.

[0019] Furthermore, by weight, the water-soluble fertilizer includes the following raw materials:

[0020] 5 - 10 parts of the fertilizer composition according to any one of the first aspect, 15 - 20 parts of urea, 10 - 16 parts of potassium dihydrogen phosphate, 5 - 10 parts of potassium sulfate, and 55 - 65 parts of water.

[0021] Furthermore, by weight, the water-soluble fertilizer includes the following raw materials:

[0022] 8 parts of the fertilizer composition according to any one of the first aspect, 17 parts of urea, 12 parts of potassium dihydrogen phosphate, 8 parts of potassium sulfate, and 60 parts of water.

[0023] Fourthly, the present invention provides the application of the fertilizer composition according to any one of the first aspect or the water-soluble fertilizer according to any one of the third aspect in the cultivation of Angelica sinensis.

[0024] The above technical solutions provided by the embodiments of the present invention have at least the following advantages compared with the prior art:

[0025] The embodiments of the present invention provide a fertilizer composition and its application in the preparation of water-soluble fertilizers. The present invention uses the Cinnamon Twig and Hoelen Decoction residue, Rabdosia lanceolata, and glycerol in appropriate proportions, which can significantly promote the growth and development of plant roots, and is particularly suitable as a high-efficiency fertilizer additive for the preparation of special water-soluble fertilizers for traditional Chinese medicines such as Angelica sinensis, so as to achieve the effects of increasing the yield and improving the quality of Angelica sinensis. The present invention provides a new technical means for the secondary utilization of the Cinnamon Twig and Hoelen Decoction residue and the cultivation of traditional Chinese medicines such as Angelica sinensis, and has wide practical application value. Specifically:

[0026] 1. Nutrient release and soil improvement of the Cinnamon Twig and Hoelen Decoction residue

[0027] As the waste after traditional Chinese medicine decoction, the Cinnamon Twig and Hoelen Decoction residue is rich in various nutrient elements such as organic matter, nitrogen, phosphorus, potassium, and trace elements. These components slowly decompose in the soil, which can provide continuous and stable nutrient supply for plants. At the same time, the organic matter in the medicine residue can improve the soil structure, increase the water and fertilizer retention capacity of the soil, and create a good growth environment for plant roots.

[0028] 2. Biological activity and growth promotion effect of Rabdosia lanceolata

[0029] The extract of Rabdosia lanceolata contains various bioactive substances such as flavonoids and polyphenols, which have the effects of promoting plant growth and enhancing plant stress resistance. In the fertilizer composition, the addition of Rabdosia lanceolata can activate the physiological metabolic activities in plants, promote root development, improve the absorption and utilization efficiency of nutrients by plants, thereby accelerating the plant growth rate and improving the overall quality of plants.

[0030] 3. Moisture retention, penetration and synergistic effect of glycerol

[0031] As an excellent humectant and penetrant, glycerol plays an important role in the fertilizer composition. It can maintain the stability of the fertilizer solution and prevent nutrient loss due to water evaporation. At the same time, glycerol can also enhance the permeability of the fertilizer solution to plant roots, making nutrients more easily absorbed and utilized by plants. In addition, glycerol can also produce a synergistic effect with the components in the medicine residue and the extract of Rabdosia lanceolata, improving the overall effect of the fertilizer.

[0032] In summary, the fertilizer composition proposed in the present invention achieves the synergistic effect between the Lingguishugan decoction residue, the narrow-line-line-striped fragrant tea vegetable and glycerol through scientific proportioning and careful combination, and provides efficient nutrient support for plant growth and development. In particular, in the preparation of special water-soluble fertilizers for Chinese medicinal materials such as angelica, the fertilizer composition can significantly promote root growth, improve yield and quality, and provide a new technical means and solution for the cultivation of Chinese medicinal materials.
