Description

Method for producing a bead-shaped biodegradable plant growth supplement using extract of the scutellaria baicalensis and plant growth supplement produced thereby

[0001] The present invention relates to a method for producing a bead-shaped biodegradable plant growth supplement using an extract of the seaweed moss, and to a plant growth supplement produced thereby, and more particularly, to a method for producing a bead-shaped biodegradable plant growth supplement using an extract of the seaweed moss, which is a seaweed byproduct that is difficult to use for food, thereby supplying balanced nutrients for crop growth and effectively increasing crop growth, and to a plant growth supplement produced thereby.

[0002] Traditionally, agricultural technology has been developed with a focus on increasing agricultural production. The production of agricultural products per unit area has rapidly increased due to the development and production of various agricultural materials with systematized technology and their appropriate use by farmers. In the process of increasing agricultural production, the use of chemical fertilizers (inorganic fertilizers) and crop protection agents (chemical pesticides) has also continuously increased.

[0003] However, since the 1990s, environmental problems such as groundwater contamination due to excessive use of nitrogen and phosphorus contained in excessive chemical fertilizers and crop protection agents have emerged, and concerns about the harmful effects of mass use of chemical fertilizers on humans and livestock have begun to increase.

[0004] Accordingly, the government has planned to reduce chemical fertilizers along with full support for eco-friendly agriculture, and the development and use of eco-friendly agricultural materials are being encouraged, and interest in by-product fertilizers utilizing natural materials as an alternative to chemical fertilizers is increasing.

[0005] The need for byproduct fertilizers is being emphasized to restore the fertility of depleted farmland and to practice environmentally friendly agriculture. In line with this, the demand for byproduct fertilizers is increasing in line with the government's policy to promote environmentally friendly agriculture.

[0006] Byproduct fertilizers are largely divided into composted organic fertilizers and organic fertilizers depending on whether they are composted. Composted organic fertilizers are fertilizers that are made by mixing organic resources such as livestock manure, food waste, and sawdust and then composting them. Organic fertilizers are fertilizers that utilize organic materials in an uncomposted state using various types of residues.

[0007] Byproduct fertilizers have been known to provide nutrients that plants need, restore soil fertility, soften the soil, and enhance cold resistance, as well as prevent nutrient leaching and increase nutrient availability.

[0008] However, although by-product fertilizers are important due to the above-mentioned advantages, they have a lower content of nitrogen, phosphorus, and potassium by weight compared to chemical fertilizers, and do not contain sufficient amino acids and various minerals essential for crop growth, so their role as a nutrient is limited, which interferes with the balanced growth of plants, and in areas where by-product fertilizers are supplied, plants are frequently affected by diseases and pests due to decreased immunity, which reduces crop production and also causes problems such as a decline in the taste and quality of crops.

[0009] Meanwhile, since 2015, the sea cucumber has been one of the representative harmful marine plants that has been carried in by sea winds and currents from the seas of China every year, covering fish farms and causing damage to fishermen and destruction of the marine ecosystem.

[0010] The mineral content of this sea cucumber cap is highest in potassium (K) relative to its fresh weight, followed by calcium (Ca), sodium (Na), and magnesium (Mg). The Na / K ratio is relatively low at 0.4, and trace minerals such as aluminum (Al), iron (Fe), zinc (Zn), and manganese (Mn) are contained, which correspond to essential macronutrients and trace elements for plants.

[0011] Additionally, seaweed contains various plant hormones, so soil made from seaweed byproducts can directly help plant growth.

[0012] These sea cucumber hats are rich in various inorganic substances and plant hormones due to their nature as sea cucumbers, and if they are properly processed, such as through a desalination process, they have sufficient industrial value. However, they cannot be used for food, and since there is no plan for consumption at a commercial level, only a very small amount is used compared to the amount collected, and the rest is incinerated or discarded.

[0013] Accordingly, the inventor of the present invention completed the present invention by confirming that by recycling seaweed by-product, seaweed that is difficult to use for food, and using it as a plant growth supplement, it is possible to supply balanced nutrients and effective ingredients for plant growth while promoting plant growth.

[0045] 1. Manufacturing step of the extract beads from the sedge (S100)

[0046] The above step (S100) of manufacturing a bead of a sedge-like plant extract is a step of manufacturing a bead of a sedge-like plant extract using a sedge-like plant extract.

[0047] In the step of manufacturing the Sargassum horneri extract bead (S100), the Sargassum horneri extract bead can be manufactured using the Sargassum horneri extract extracted from Sargassum. The Sargassum horneri is biologically classified as a member of the Sargassum family, the Sargassum order, the Brown Algae class, the Brown Algae order in the Plant kingdom, and is mainly distributed on the western coast of the North Pacific Ocean, growing in the lower intertidal zone. In the coastal waters of Korea, it is easily observed that a part of its body floats on the water surface during low tide, and it is the most common species that constitutes a marine forest, but young individuals are edible, and in the spring, they fall off the rocks and float on the coast in the form of floating leaves.

[0048] The aforementioned Sargassum horneri is yellowish-brown, with stems that grow from button-shaped roots, often branching upwards and elongating in a single strand or sometimes bifurcating. Its atopic dermatitis-suppressing, anti-inflammatory, and heavy metal adsorption properties have been reported, and screening experiments have revealed antioxidant, adipocyte-inhibiting, cancer cell proliferation-inhibiting, and anticoagulant effects.

[0049] In the step of manufacturing the above-mentioned Gastrodia elata extract beads (S100), the Gastrodia elata extract beads may be manufactured through the following processes: (1) Gastrodia elata washing and drying step, (2) Gastrodia elata cutting step, (3) Gastrodia elata hot water extraction step, (4) sodium alginate extraction step, (5) mixing step, (6) calcium chloride aqueous solution manufacturing step, (7) bead manufacturing step, and (8) Gastrodia elata extract bead manufacturing step.

[0050] (1) Washing and drying steps of the swan hat

[0051] The above-mentioned step of washing and drying the snail hat is the step of washing and then drying the snail hat.

[0052] In the above-described washing and drying step of the sedge moth, foreign substances, salt, and contaminants attached to the sedge moth can be removed by washing the sedge moth. For example, the washing and drying step of the sedge moth can be performed by washing the sedge moth using a mixed solution of green tea leaf fermentation water and grapefruit seed extract in a weight ratio of 70:30, dehydrating the sedge moth, and then storing it at a temperature of 20 to 30°C for 20 to 40 hours and drying it.

[0053] In the above-mentioned step of washing and drying the mugwort, the green tea leaf fermented water can remove the fishy smell or off-flavor of the mugwort. The green tea leaf fermented water can be a green tea leaf fermented water prepared by the following method.

[0054] That is, in order to manufacture the above-mentioned green tea leaf fermented water, first, green tea leaves can be collected and washed to remove foreign substances attached to the green tea leaves.

[0055] Green tea, as mentioned above, is a popular beverage consumed worldwide. Its main components include catechins, caffeine, amino acids, vitamins, and minerals, and these components are reported to exhibit various physiological activities. In particular, catechins, one of the active ingredients of green tea, are known to have anti-tumor, anti-cancer, antioxidant, apoptosis-inducing, anti-angiogenic, and cholesterol-lowering effects.

[0056] Next, the washed green tea leaves can be dried.

[0057] The above drying can be carried out in a well-ventilated, shaded place or in a dryer to prevent chlorophyll from being destroyed and the unique aroma of green tea from disappearing when dried in the sun. For example, the drying can be carried out by drying for 20 to 40 hours in a dryer maintained at a temperature of 30 to 40°C and a humidity of 40 to 60%.

[0058] That is, in the drying of the green tea raw leaves, the moisture contained in the green tea raw leaves is gradually and evenly evaporated as described above, so that the unique taste and aroma of green tea can be more easily expressed, and by destroying the cell tissue of the green tea raw leaves to facilitate the penetration of air, the fermentation process is promoted, so that the taste and aroma of green tea can be strongly infused in the fermented green tea leaf water.

[0059] Next, the dried green tea leaves can be heated and roasted.

[0060] The above roasting may be carried out in two stages of first roasting and second roasting to ensure that the fragrance and useful components of the dried green tea leaves are sufficiently extracted. Specifically, the first roasting may be carried out by heating the dried green tea leaves in a container heated to a temperature of 200 to 230°C for 1 to 5 minutes, followed by first cooling at a temperature of 50 to 60°C for 20 to 80 minutes, and the second roasting may be carried out by heating the first-cooled green tea leaves in a container heated to a temperature of 120 to 150°C for 5 to 10 minutes, followed by cooling at a temperature of 30 to 40°C for 100 to 200 minutes.

[0061] Next, water is mixed with the roasted green tea leaves, and then the roasted green tea leaves are removed to produce fermented green tea leaf water.

[0062] The above green tea leaf fermented water can be prepared by mixing 1,800 to 2,200 parts by weight of water at a temperature of 50 to 60°C with 100 parts by weight of the total content of the roasted green tea leaves, and then steeping for 10 to 20 hours.

[0063] In addition, the grapefruit seed extract can be prepared by mixing 100 parts by weight of grapefruit seeds with 2,000 to 3,000 parts by weight of water, heating at a temperature of 90 to 95°C for 3 to 7 hours, and extracting the mixture with hot water. The grapefruit seeds contain ascorbic acid, sterol, dehydroascorbic acid, tocopherol, palmitic acid, etc. as main components, and various effective ingredients are known to inhibit the growth of microorganisms by weakening the enzyme activity and permeability related to the cell membrane of microorganisms and inhibiting cellular respiration.

[0064] In particular, the grapefruit seeds contain bioflavonoids, naringin and citral, as their main components, so they not only have excellent antibacterial and antioxidant effects, but also have excellent antibacterial effects against gram-positive and gram-negative bacteria as well as mold.

[0065] (2) Cutting stage of the swan hat

[0066] The above-mentioned step of cutting the dried sedge is a step of crushing and cutting the dried sedge.

[0067] In the above step of cutting the dried dandelion, the dried dandelion is cut using a known crusher, thereby allowing useful components contained in the dried dandelion to be easily extracted in a subsequent process. For example, in the step of cutting the dried dandelion, the dried dandelion can be cut into units of 0.5 to 1 cm in length.

[0068] (3) Hot water extraction stage of the snail shell

[0069] The above step of extracting the cut dandelion from hot water is a step of extracting the cut dandelion from hot water to produce a dandelion from hot water extract.

[0070] In the above step of extracting the sedge of ...

[0071] (4) Sodium alginate extraction step

[0072] The above sodium alginate extraction step is a step of manufacturing sodium alginate by extracting the remaining solid matter of the sea squirt after the hot water extraction.

[0073] In general, the above sodium alginate is a white to light yellow fiber, grain, granule or powder with the chemical formula (C6H7O6Na)n, and is a biologically derived substance with almost no odor and no taste. It is used as a stabilizer for ice cream, an adhesive for ketchup, mayonnaise, sauce, etc., a clarifying agent for sake, a gelling agent, an emulsifier, a thickener, etc. to increase the adhesiveness and viscosity of food, promote emulsion stability, and improve the physical properties and texture of food.

[0074] The above sodium alginate is a polymeric substance that exists in various grades through a refining process. It becomes viscous when dissolved in water, and the pH of a 1% aqueous solution is nearly neutral, at 6-8. Sodium alginate hardens when exposed to sodium chloride (NaCl) or at low pH levels. Due to this property, sodium alginate has been used as a thickener.

[0075] In the sodium alginate extraction step, any one of the following methods may be selected and used as the extraction method for the solid material of the sea squirt: hot water extraction, cold immersion extraction, reflux cooling extraction, solvent extraction, steam distillation, ultrasonic extraction, dissolution, and pressing. In addition, the desired extract may additionally undergo a conventional fractionation process, and may be purified using a conventional purification method.

[0076] For example, in the sodium alginate extraction step, the extraction of the sodium alginate can be performed according to the method of Calumpong et al (1999). Specifically, the sodium alginate is first pretreated by adding 800 mL of 2% formaldehyde to 25 g of the spore-forming agent at room temperature for 24 hours, then the spore-forming agent is washed, and a second pretreatment is performed in 800 mL of 0.2 M hydrochloric acid (HCl) for 24 hours. After that, the spore-forming agent that has undergone the pretreatment process is immersed in 1 L of 2% sodium carbonate (Na2CO3) and extracted at 60 to 80°C for 1 to 3 hours, and the extracted solution is centrifuged at 3200 rpm for 25 minutes, and then precipitated in 3 times the volume of 95% ethanol, and finally, at 60°C. It can be manufactured by drying for 50 hours.

[0077] (5) Mixing stage

[0078] The above mixing step is a step of preparing a mixed solution by mixing the above-mentioned hot water extract of the scutellaria baicalensis and the above-mentioned sodium alginate.

[0079] For example, in the mixing step, the mixed solution can be prepared by mixing 100 parts by weight of the hot water extract of the sedge plant and 1 to 10 parts by weight of the sodium alginate, and then stirring.

[0080] (6) Calcium chloride aqueous solution manufacturing step

[0081] The above calcium chloride aqueous solution manufacturing step is a step of manufacturing a calcium chloride aqueous solution by mixing calcium chloride and water.

[0082] For example, in the step of preparing the calcium chloride aqueous solution, the calcium chloride aqueous solution can be prepared by mixing 1 to 5 parts by weight of calcium chloride with 100 parts by weight of water and then stirring.

[0083] (7) Bead manufacturing step

[0084] The above bead manufacturing step is a step of manufacturing beads by spraying the above mixed solution into the above calcium chloride aqueous solution.

[0085] In the above bead manufacturing step, granular beads can be manufactured by spraying the mixed solution into the calcium chloride aqueous solution and coagulating it. The configuration of manufacturing beads by spraying the mixed solution into the calcium chloride aqueous solution in the bead manufacturing step is a known technology, and thus, for the convenience of explanation and clarity of the technical idea of ​​the present invention, a detailed description thereof will be omitted.

[0086] (8) Manufacturing step of the extract beads of the sedge plant

[0087] The above step of manufacturing the extract beads of the sedge of the common sedge is a step of manufacturing the extract beads of the sedge of the common sedge by filtering and separating the beads and then drying them.

[0088] For example, in the step of manufacturing the above-mentioned sedge extract beads, the beads are filtered using a known filter to separate only the beads, and then the beads are dried at a temperature of 25 to 35°C to remove moisture, thereby manufacturing sedge extract beads containing a large amount of essential elements required by plants.

[0089] 2. Material preparation stage (S200)

[0090] The above material preparation step (S200) is a step of preparing materials including the above-mentioned sedge bead extract.

[0091] Materials prepared for manufacturing a biodegradable plant growth supplement in the above material preparation step (S200) include a bead of extract of the Korean yam, PLA (Polylactic Acid) resin, PBAT (Polybutylene Adipate Terephthalate) resin, fermented sawdust, fly ash, a binder, an insecticide, a pine extract, potassium phosphate (K3PO4), and rock phosphate.

[0092] The above-mentioned extract beads of the sedge plant can be used as beads of the sedge plant extract manufactured by the above-described method.

[0093] The above PLA (Polylactic Acid) resin is a thermoplastic polyester of lactide or lactic acid, and can be manufactured by polymerizing lactic acid produced by fermenting starch extracted from corn, potatoes, etc., for example. The PLA resin emits significantly less environmentally harmful substances such as CO2 during the use or disposal process than petroleum-based materials such as polyvinyl chloride (PVC), and has environmentally friendly characteristics in that it can be easily decomposed in the natural environment even when disposed of.

[0094] The above polybutylene adipate terephthalate (PBAT) resin is a biodegradable bioplastic and is an environmentally friendly material that is 100% decomposed in the ground within 6 months. The PBAT resin can be obtained by polycondensation of 1,4-butanediol, adipic acid, and terephthalic acid according to a generally known method.

[0095] These PBAT resins can be synthesized directly using the general method, or can be used by obtaining commercially available PBAT resins, such as the above-mentioned product names ECOPLEX (BASF) or PBG7070 (Samsung Fine Chemicals).

[0096] In addition, the PBAT resin may have a weight average molecular weight of 150,000 to 400,000. As the PBAT resin has this molecular weight range, the compatibility and processability with other compositions constituting the PBAT resin and the coating composition may be improved, and the PBAT resin may exhibit improved physical properties, etc., due to the relatively high molecular weight.

[0097] The above sawdust fermentation product can be a sawdust fermentation product manufactured by the following manufacturing method.

[0098] First, to manufacture the above sawdust fermentation product, sawdust, rice straw, rice bran, and microbial culture solution can be prepared.

[0099] The above sawdust may be a mixture of crusher sawdust, sawdust from lumber mills, etc. recovered during processing at a wood factory, and the above sawdust may be composed of 50 to 60% cellulose, 10 to 20% hemicellulose, 20 to 30% lignin, and other components including residual ash, crude fat, tannin, and pigment.

[0100] The above microbial culture solution is obtained by mixing a medium with water, inoculating the strain, and culturing at 35 to 40°C under aerobic conditions. The medium can be prepared by adding tryptone, malt extract, sodium citrate, yeast extract, glucose, sodium chloride (NaCl), and potassium hydrogen phosphate (K2HPO4) to purified water. For example, the medium can be prepared by mixing 4 to 6 g of tryptone, 1 to 3 g of malt extract, 3 to 5 g of sodium citrate, 2 to 4 g of yeast extract, 1 to 3 g of glucose, 0.5 to 2.5 g of sodium chloride, and 0.1 to 1 g of potassium hydrogen phosphate per 1 liter of distilled water. Next, 2 liters (ℓ) of the above-mentioned medium can be mixed with 20 liters (ℓ) of purified water, inoculated with a fermentation strain, and cultured at 40 to 42°C for 8 to 12 days to prepare a microbial culture solution.

[0101] At this time, as the fermentation strain, one or more strains selected from the group consisting of Bacillus subtilis, Bacillus stearothermophilus, Rhodopsudomonas, Rhodospirillum, Bacillus sonorensis, and Bacillus thermoamylovorans may be used.

[0102] Next, the prepared sawdust, rice straw, rice bran and microbial culture solution are mixed, and the mixture composed of the mixed sawdust, rice straw, rice bran and microbial culture solution can be fermented.

[0103] In the above step, a mixture is prepared by mixing 80 to 120 parts by weight of sawdust, 40 to 60 parts by weight of rice straw, 20 to 40 parts by weight of rice bran, and 10 to 20 parts by weight of microbial culture medium, and then the mixture is stored at a temperature of 50 to 55°C and a humidity of 60 to 65% for 5 to 10 days to proceed with fermentation.

[0104] Next, the fermented mixture can be dried to produce a sawdust fermentation product.

[0105] In the above step, the sawdust fermentation product can be produced by drying the fermented mixture at a temperature of 38 to 42°C for 20 to 40 hours.

[0106] The above fly ash can be used to improve the cohesion of plant growth promoters.

[0107] The above fly ash refers to ash (coal ash) collected by a dust collector from the flue gas of a boiler burning pulverized coal, and the fly ash can be included in a binding agent composition to improve cohesion.

[0108] The above fly ash is produced by crushing coal into fine particles at a thermal power plant and injecting it into the furnace at high speed together with hot air, where most of the minerals contained in the coal are instantly combusted in a suspended state at a temperature range of 1300 to 1700℃, which is higher than the melting point. After combustion, the coal can be collected by a dust collector.

[0109] In the case of anthracite coal, about 15-26% of coal ash is generated, and it can be broadly divided into bottom ash, which is a lump that falls to the bottom of the boiler and is cooled by water, and cinder ash, which is collected in the hopper at the bottom of the economizer or air preheater. Most of the coal ash generated in Korea that can be recycled is generated at coal-fired power plants, and the recycling sector is utilized in the cement, civil engineering, construction, and agricultural and fisheries sectors.

[0110] The above binder is not a chemical binder harmful to the human body, but uses starch to bond a composition such as a bead of ...

[0111] To prepare the above binder, first, starch and water can be mixed to prepare a starch solution.

[0112] In the above starch solution, the starch can provide adhesiveness for binding the composition constituting the binder, and the starch solution can be mixed in a weight ratio of 50 to 70 parts by weight of starch and 180 to 220 parts by weight of water.

[0113] In addition, the type of the starch is not particularly limited, and for example, at least one selected from the group consisting of corn starch, glutinous corn starch, tapioca starch, potato starch, sweet potato starch, rice starch, and wheat starch may be used.

[0114] In addition, the starch includes unmodified starch or specific modified starch. Unmodified starch is a starch obtained from a conventional starch manufacturing process, and is a concept in contrast to modified starch (e.g., acid-treated starch, oxidized starch, acetylated disodium acetate, acetyl phosphate disodium acetate, octenyl succinate starch, disodium phosphate, monostarch phosphate, phosphated disodium phosphate, starch acetate, hydroxypropyl phosphate disodium hydroxypropyl starch, etc.) whose properties (viscosity, heat stability, freeze-thaw stability) have been changed by chemical treatment or heat treatment. The specific modified starch includes acid-treated starch, oxidized starch, starch acetate, or starch octenyl succinate.

[0115] Next, a pine needle powder solution can be prepared by mixing pine needle powder, agar powder, and water, and then the pine needle powder solution can be heated.

[0116] Specifically, the pine needle powder solution can be prepared by mixing 5 to 15 parts by weight of pine needle powder, 20 to 40 parts by weight of agar powder, and 80 to 100 parts by weight of water in a weight ratio, and then heating at a temperature of 90 to 95°C for 10 to 20 minutes.

[0117] The above pine needle powder can be manufactured by crushing pine needles, and the structure of the pine needles includes not only the cuticle and epidermis, but also an inner epidermis inside the epidermis, so that evaporation of moisture is suppressed, and the pine resin component produced around the pine needle's air is contained in the pine needle powder as is, so that when mixed with starch, agar powder, etc., it can promote hardening and increase binding strength.

[0118] The above pine needle powder contains pine resin and can increase the calorific value of solid fuel. The above pine needle powder can be obtained by collecting fallen pine needles and crushing them into a size range of 10 to 200 mesh to obtain a reddish pine needle powder.

[0119] The above agar powder is manufactured by powdering agar, and the above agar powder can be used as a gelling agent. The agar used as a gelling agent is a dried product of agar made from seaweed of the Gelidium family, and is composed mostly of polysaccharides, with 15% moisture, 2% protein, 3.5% ash, and less than 0.5% fat. The polysaccharides are composed of 70% agarose, a neutral polysaccharide, and 30% agaropectin, an acidic polysaccharide.

[0120] Additionally, agar has a strong hydrophilicity towards water, so it has a great ability to maintain moisture in a constant form. Agar usually absorbs about three times its weight in water and forms a stable gel at a concentration of 0.4%.

[0121] In addition, agar easily gels at around 40℃ when reacted with water even in small amounts, and does not melt below 80-85℃, so it can be used even in the hot summer months and can be stored in a gel state.

[0122] Agar, a representative type of seaweed, has long been widely used in medicines, food, and industrial raw materials. With annual domestic production reaching approximately 3,600 tons, it is a relatively abundant resource. However, actual utilization only accounts for about 65% of total production, with the remainder largely unused, resulting in low added value relative to its resource value.

[0123] Currently, agar is primarily composed of carbohydrates. It is non-toxic and harmless to the human body when consumed, making it a popular food ingredient. Furthermore, it readily decomposes naturally, thus preventing any harmful environmental impact and contributing to the prevention of environmental pollution. Furthermore, unlike gelatin, agar extracted from seaweed has a relatively high freezing point, allowing it to remain in a gel state even at room temperature, making it easier to gel and use than other gelling agents.

[0124] Next, a binder can be prepared by mixing palm fruit shell powder into the starch solution and pine needle powder solution.

[0125] The above binder can be prepared by mixing 80 to 120 parts by weight of the starch solution, 40 to 60 parts by weight of the pine needle powder solution, and 5 to 15 parts by weight of the palm fruit shell powder in a weight ratio.

[0126] The above palm fruit shell powder is manufactured by drying, pressing, and then crushing only the fiber of discarded palm fruit shells. The fiber of dried palm fruit shells can be used while the color of the fiber of the palm fruit shell naturally changes from dark brown to light brown or yellow brown due to sunlight during drying. The fiber of the dried palm fruit shells can be used by cutting it into units of 1 to 10 mm in length.

[0127] The above insecticidal substance is uniformly mixed into the coating composition and imparts insecticidal and sterilizing effects to the horticultural eco-friendly pot (10), thereby preventing bugs, mites, insects, etc. from breeding or gathering in the horticultural eco-friendly pot (10). For example, as the insecticidal substance, at least one substance selected from the group consisting of Orysastrobin, Thiamethoxam, Clothianidin, Carbosulfan, Tiadinil, Probenazole, and Benfuracarb may be used.

[0128] Specifically, the above insecticidal substance can be used by mixing it in a weight ratio of 40 wt% of Orysastrobin and 60 wt% of Thiamethoxam.

[0129] The above pine tree extract can be manufactured by extracting from the pine tree, and the above pine tree extract has insecticidal, antibacterial, and anti-insect effects against pollutants, mites, pests, etc.

[0130] That is, the above-mentioned Picrasma quassioides contains quassin, which is very bitter, has a yellow coating on its bark, and grows to about 20 m in height. The leaves are pinnately compound, the small leaves are ovate, the base is round, and the tip is sharp. The flowers are yellow-green, monoecious, and bloom in the form of cymes around May to June, and the fruit is an oval-shaped drupe that ripens to red around September. Each part, including the leaves, bark, stem, and root, is used as a medicinal ingredient, and it has the effects of clearing heat and moisture, strengthening the stomach, killing insects, and detoxifying, so it is effective for indigestion, bacterial diarrhea, gastroenteritis, biliary tract infection, and tonsillitis, and has been used in folk medicine as a stomachic, indigestion, gastritis, and loss of appetite.

[0131] The above potassium phosphate (K3PO4) is a general term for salts of phosphoric acid and potassium. It is a phosphate obtained by reacting an aqueous potassium hydroxide solution and is used as a raw material for potassium fertilizer. The above potassium phosphate (K3PO4) promotes photosynthesis and protein synthesis from amino acids in plants, thereby promoting plant growth.

[0132]

[0133] The above rock phosphate is an ore containing a large amount of calcium phosphate, and representative materials include apatite, phosphate soil, and guano, and it is the main raw material for phosphate fertilizer. The above rock phosphate is a natural compound mainly composed of phosphoric acid, nitrogen (N), calcium oxide (CaO), and magnesium oxide (MgO), and is used in fertilizer composition by utilizing the principle of dissolving in 2% citric acid.

[0134] The phosphoric acid contained in the above phosphate rock has the property of being dissolved in citric acid and converted into free phosphoric acid, and the citric acid is produced by black mold (Aspergillus niger) and is used to decompose phosphoric acid. Calcium and phosphorus are the main components of the phosphate rock, and the water solubility, spherical solubility, and insolubility of the phosphate fertilizer made from the phosphate rock are determined depending on the ratio of calcium and phosphorus. Consequently, the lower the phosphorus content compared to calcium, the stronger the spherical solubility, increasing the sustainability of the fertilizer, and the higher the absorption rate of phosphoric acid in plants, which increases the value of the fertilizer.

[0135] 3. Material mixing dough stage (S300)

[0136] The above material mixing dough step (S300) is a step of manufacturing dough by mixing the prepared materials at a certain weight ratio.

[0137] In the above material mixing dough step (S300), a dough can be prepared by mixing the materials prepared in a weight ratio of 30 to 50 parts by weight of the above-mentioned sedge extract beads, 2 to 8 parts by weight of PLA (Polylactic Acid) resin, 5 to 15 parts by weight of polybutylene adipate terephthalate (PBAT) resin, 1 to 10 parts by weight of fermented sawdust, 1 to 5 parts by weight of fly ash, 5 to 15 parts by weight of binder, 1 to 3 parts by weight of insecticidal substance, 1 to 3 parts by weight of pine extract, 2 to 4 parts by weight of potassium phosphate (K3PO4), and 2 to 4 parts by weight of rock phosphate.

[0138] 4. Molding stage (S400)

[0139] The above molding step (S400) is a step of manufacturing a molded body by compression molding the dough.

[0140] In the above molding step (S400), the dough can be put into a press mold and then compression molded into a spherical granular shape to produce a molded body. For example, in the above molding step (S400), the dough can be put into the press mold and rolled, and the dough can be additionally attached to produce a larger size (or particle size), thereby allowing for a variety of molding production in sizes suitable for the shape and size of the product desired by the user or consumer.

[0141] In the present invention, the configuration of manufacturing a molded body by putting the dough into a press mold and compressing it into a spherical granular shape is a known technology, and for the convenience of explanation and the technical convenience of the present invention, a detailed description thereof will be omitted.

[0142] 5. Drying stage (S500)

[0143] The above drying step (S500) is a step for manufacturing a plant growth supplement by drying the molded body.

[0144] In the above drying step (S500), the molded body can be naturally dried to produce a plant growth supplement. For example, in the above drying step (S500), the plant growth supplement can be produced by naturally drying the molded body at a temperature of 20 to 40°C for 1 to 3 days.

[0145] Hereinafter, with reference to the attached drawings, a preferred embodiment of a method for manufacturing a bead-type biodegradable plant growth supplement using an extract of the sedge plant according to an embodiment of the technical idea of ​​the present invention will be described in more detail.

[0148] At this time, the above-mentioned extract beads of the scutellaria baicalensis were washed using a mixed solution of fermented green tea leaf water and grapefruit seed extract at a weight ratio of 70:30, and then the scutellaria baicalensis was dehydrated and dried by storing at a temperature of 25℃ for 30 hours, and the dried scutellaria baicalensis was cut into units of 0.5 to 1 cm in length, and 1000 parts by weight of the cut scutellaria baicalensis was mixed with 1000 parts by weight of water, and then heated at a temperature of 95℃ for 3 hours to extract hot water, and then the filtrate was filtered to prepare a scutellaria baicalensis hot water extract, and the remaining scutellaria baicalensis solids after the hot water extraction were extracted to prepare sodium alginate, and 5 parts by weight of the sodium alginate was mixed with 100 parts by weight of the scutellaria baicalensis hot water extract, and then stirred. A mixed solution was prepared, and a calcium chloride aqueous solution was prepared by mixing 3 parts by weight of calcium chloride with 100 parts by weight of water and stirring, and the mixed solution was sprayed on the calcium chloride aqueous solution to coagulate, thereby preparing granular beads, and the beads were filtered using a known filter to separate only the beads, and the beads were dried at a temperature of 30°C to remove moisture, and the prepared beads were used as extract beads of the sedge of the plant.

[0149] Next, a dough was prepared by mixing the above-prepared materials in a weight ratio of 40 parts by weight of the extract beads of the above-mentioned sedge hat, 5 parts by weight of PLA (Polylactic Acid) resin, 10 parts by weight of polybutylene adipate terephthalate (PBAT) resin, 5 parts by weight of fermented sawdust, 3 parts by weight of fly ash, 10 parts by weight of binder, 2 parts by weight of insecticidal substance, 2 parts by weight of pine tree extract, 3 parts by weight of potassium phosphate (K3PO4), and 3 parts by weight of rock phosphate.
