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.

[0006] In a first aspect, the present invention provides a fertilizer composition, which comprises the following raw materials in parts by weight: 7-12 parts of the residue of Ling Gui Zhu Gan Decoction, 2-5 parts of Scutellaria baicalensis and 15-25 parts of glycerol.

[0007] Furthermore, the fertilizer composition comprises the following raw materials in parts by weight: 10 parts of the dregs of Ling Gui Zhu Gan Decoction, 3 parts of Herba Lycopodii Sinensis and 20 parts of glycerol.

[0008] Furthermore, the preparation method of the fertilizer composition comprises the following steps: Mixing and grinding the Lingguishugan decoction residue and the narrow-lined schizonepeta tenuifolia to obtain a first mixed material; Subjecting the first mixed material to oxygen-rich microwave plasma treatment to obtain a second mixed material; The second mixed material is decocted, filtered, concentrated and dried to obtain an extract; The extract is added into the glycerin for grinding to obtain the fertilizer composition.

[0009] Furthermore, the working condition parameters of the oxygen-enriched microwave plasma treatment include: using oxygen and argon with a volume ratio of 7:1 as the working medium, a microwave power of 280-400W, and treating in glow discharge mode for 60-90 seconds and then continuing to introduce oxygen for 5-10 minutes.

[0010] Furthermore, the working condition parameters of decoction include: the number of decoctions is 1 to 3 times, and the decoction time is 60 to 120 minutes; the working condition parameters of grinding include: the grinding speed is 1500 to 2000 rpm, and the grinding time is 5 to 10 minutes.

[0011] In a second aspect, the present invention provides use of the fertilizer composition described in any one of the first aspects in preparing a water-soluble fertilizer.

[0012] In a third aspect, the present invention provides a water-soluble fertilizer, comprising the fertilizer composition described in any one of the first aspects and a basic fertilizer, wherein the basic fertilizer comprises at least one of a nitrogen-containing water-soluble substance, a potassium-containing water-soluble substance and a phosphorus-containing water-soluble substance.

[0013] Furthermore, the water-soluble fertilizer comprises the following raw materials in parts by weight: 5 to 10 parts of the fertilizer composition according to any one of the first aspects, 15 to 20 parts of urea, 10 to 16 parts of potassium dihydrogen phosphate, 5 to 10 parts of potassium sulfate and 55 to 65 parts of water.

[0014] Furthermore, the water-soluble fertilizer comprises the following raw materials in parts by weight: 8 parts of the fertilizer composition described in any one of the first aspects, 17 parts of urea, 12 parts of potassium dihydrogen phosphate, 8 parts of potassium sulfate and 60 parts of water.

[0015] In a fourth aspect, the present invention provides use of the fertilizer composition described in any one of the first aspect or the water-soluble fertilizer described in any one of the third aspect in Angelica sinensis planting.

[0016] The above technical solution provided by the embodiment of the present invention has at least the following advantages compared with the prior art: The embodiment of the present invention provides a fertilizer composition and its application in the preparation of water-soluble fertilizer. The present invention uses a combination of Ling Gui Shu Gan Tang residue, Scutellaria baicalensis and glycerol in appropriate proportions, which can significantly promote the growth and development of plant roots. It is also particularly suitable as a high-efficiency fertilizer additive for the preparation of special water-soluble fertilizers for Chinese medicinal materials such as Angelica sinensis, so as to increase the yield of Angelica sinensis and improve its quality. The present invention provides a new technical means for the secondary utilization of Ling Gui Shu Gan Tang residue and the planting of Chinese medicinal materials such as Angelica sinensis, and has a wide range of practical application value. Specifically: 1. Nutrient release and soil improvement of Lingguishugan decoction residue The residue of Ling Gui Shu Gan Tang, as the waste after decoction of traditional Chinese medicine, is rich in organic matter, nitrogen, phosphorus, potassium and other nutrients and trace elements. These components slowly decompose in the soil and can provide a continuous and stable supply of nutrients for plants. At the same time, the organic matter in the residue can also improve the soil structure, increase the soil's ability to retain water and fertilizer, and create a good growth environment for plant roots.

[0017] 2. Biological activity and growth-promoting effect of N. serrata The extract of Narrow-lined Camellia contains a variety of bioactive substances, such as flavonoids and polyphenols, which have the effect of promoting plant growth and enhancing plant stress resistance. In the fertilizer composition, the addition of Narrow-lined Camellia can activate physiological metabolic activities in the plant, promote root development, and improve the plant's absorption and utilization efficiency of nutrients, thereby accelerating plant growth and improving the overall quality of the plant.

[0018] 3. Moisturizing, penetration and synergistic effects of glycerol As an excellent moisturizer and penetrant, glycerol plays an important role in fertilizer compositions. It can maintain the stability of the fertilizer solution and prevent the loss of nutrients due to water evaporation. At the same time, glycerol can also enhance the permeability of the fertilizer solution to the plant root system, making it easier for the plant to absorb and utilize the nutrients. In addition, glycerol can also produce a synergistic effect with the ingredients in the medicinal residues and the extract of the safflower, improving the overall effect of the fertilizer.

[0019] 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.
