[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. The present invention uses Lycoris radiata extract as a natural plant-derived pesticide, which is more environmentally friendly than synthetic chemical pesticides and reduces pollution to the environment. The active ingredients in the Lycoris radiata extract are easily degraded in the environment, reducing the risk of long-term residues. The Lycoris radiata bulb is rich in various alkaloids, such as galantamine and lycorine, which have significant inhibitory or killing effects on pests and can effectively prevent and control various agricultural pests. In addition to the direct insecticidal effect, the Lycoris radiata extract can also affect the growth and development process of pests and play a certain repellent effect.

The combination of medicinal fertilizer and medicinal fertilizer can improve the disease and insect resistance of crops. Due to the combination of medicinal fertilizer and medicinal fertilizer, farmers can carry out disease and insect pest control while fertilizing, reducing the labor and time costs of additional application of medicine. Although Lycoris radiata itself is toxic, the medicinal fertilizer product prepared after scientific treatment greatly reduces the harm to humans and other non-target organisms while ensuring effectiveness against target pests.
[0022] 2. The present invention helps the Lycoris radiata extract to be evenly distributed in the fertilizer matrix by using an inert filler, thereby ensuring that the active ingredients are uniformly distributed throughout the product, improving the stability and reliability of the efficacy, avoiding the risk of drug damage caused by excessive local concentration, and protecting crops from excessive exposure to alkaloids. The micronization process makes the particles finer, increases the surface area of the active ingredients, thereby improving their diffusion rate and absorption efficiency in the soil. The finer particles are more easily absorbed by the plant roots, thereby enhancing the effectiveness of the drug fertilizer on crops. Water spraying and ultrasonic-assisted dispersion effectively prevent agglomeration between particles, ensuring good fluidity and uniformity of the mixture. Finally, large particles or lumps are removed by screening, ensuring that the particle size of the drug fertilizer raw materials is uniform, which is beneficial to the uniform spreading during the subsequent granulation and application process. Efficient mixing equipment and technical means reduce The time required for mixing has been shortened from 10 to 30 minutes, which improves production efficiency. The optimized mixing process reduces unnecessary energy consumption and reduces production costs. The strict mixing process ensures the quality consistency of each batch of products and meets the requirements of agricultural production and market sales. Each link can be monitored and adjusted to ensure the repeatability and controllability of the production process. Uniform mixing reduces the toxicity risk that Lycoris radiata extract may bring, ensuring the safety of the product to humans and other non-target organisms. Lycoris radiata extract from natural sources combined with a scientific and reasonable mixing process reduces the use of chemical pesticides and reduces the risk of environmental pollution.

[0024] Example 1
[0025] See also Figure 1 A method for preparing medicinal fertilizer using Lycoris radiata extract comprises the following steps:

[0028] S2, extraction process, extracting alkaloids from Lycoris radiata raw materials by solvent extraction to obtain an extract containing alkaloids;
[0029] Furthermore, when performing the extraction, first, the bulbs, leaves or flowers of Lycoris radiata need to be collected and cleaned to remove impurities, and then the materials are dried to reduce the moisture content, and crushed into fine powder to increase the contact area to improve the extraction efficiency, and the organic solvent is selected according to the chemical properties of the alkaloids, and the organic solvent is one or more of water, methanol, ethanol, acetone, chloroform and ethyl acetate. The crushed plant material is placed in the selected solvent and soaked for a period of time under heating to allow the alkaloids to dissolve in the solvent, and then reflux extraction is performed, that is, the mixture of the solvent and the raw material is heated under a certain pressure to make the solvent boil and condense and reflux, thereby repeatedly extracting the components in the raw material, and after a certain period of extraction, the solid residue is separated from the liquid containing the alkaloids to obtain an extract.
[0030] S3, concentration and separation, filtering and concentrating the extract, and separating the alkaloids in the concentrated extract to obtain a Lycoris radiata extract rich in alkaloids.
[0031] S4, mixing the drug and fertilizer, mixing the obtained Lycoris radiata extract into a fertilizer matrix, the fertilizer matrix is a nitrogen, phosphorus and potassium compound fertilizer matrix, to prepare a drug and fertilizer raw material with insecticidal effect.
[0032] S5, preparing the finished product, making the mixed medicinal fertilizer raw materials into granules, and drying the granular raw materials to obtain medicinal fertilizer granules, and putting the prepared medicinal fertilizer granules into a sterile packaging container for storage.
[0033] By using Lycoris radiata extract as a natural plant-based pesticide, it is more environmentally friendly than synthetic chemical pesticides and reduces pollution to the environment. The active ingredients in Lycoris radiata extract are easily degraded in the environment, reducing the risk of long-term residues. Lycoris radiata bulbs are rich in various alkaloids, such as galanthamine and lycorine, which have significant inhibitory or killing effects on pests and can effectively prevent and control a variety of agricultural pests. In addition to the direct insecticidal effect, Lycoris radiata extract can also affect the growth and development process of pests and play a certain repellent effect.
[0034] By mixing Lycoris radiata extract with nitrogen, phosphorus and potassium compound fertilizer matrix, the prepared medicated fertilizer not only has insecticidal effect, but also can provide crops with necessary nutrients and promote healthy growth. The combination of medicated fertilizer and fertilizer can improve the disease and insect resistance of crops. Due to the combination of medicated fertilizer and fertilizer, farmers can carry out disease and pest control while fertilizing, reducing the labor and time costs of additional application of pesticides. Although Lycoris radiata itself is poisonous, the medicated fertilizer products made after scientific processing can ensure effectiveness against target pests while greatly reducing the harm to humans and other non-target organisms.
[0035] By adopting advanced mixing equipment and technology, we ensure that Lycoris radiata extract and fertilizer matrix are fully and evenly mixed, which improves the consistency of product quality. By introducing intelligent control systems, we can comprehensively monitor and automate the entire production process, improve production stability and efficiency, and make the mixed medicinal fertilizer raw materials into granules and dry them, which increases the physical stability and storage life of the product.
[0036] Furthermore, before mixing the Lycoris radiata extract and the fertilizer matrix in S4, the purity and active ingredients of the Lycoris radiata extract are first tested. After the test, the ratio of the Lycoris radiata extract and the fertilizer matrix is determined. When determining the ratio, the effects of the Lycoris radiata extract at different ratios on the target pests and the effects of the fertilizer matrix at different ratios on plant growth are tested. Multiple ratios of Lycoris radiata extract and fertilizer matrix are set, which are 0.1:9.9-1:9 respectively. The control effect and safety at each ratio are evaluated through field trials, and finally the optimal ratio is determined to be 0.14:9.86.
[0037] By testing the purity and active ingredients of Lycoris radiata extract, the quality stability and consistency of the raw materials are ensured, which helps to avoid unstable product performance caused by fluctuations in raw material quality. Based on scientific test results, the optimal ratio of Lycoris radiata extract to fertilizer matrix is determined to be 0.14:9.86, which ensures the high efficiency and safety of the product. By setting multiple ratios and conducting field trials, a large amount of experimental data is collected, which provides a solid foundation for determining the optimal ratio. The effect evaluation on target pests ensures that the fertilizer products can effectively deal with specific pest problems and improve the targetedness and efficiency of prevention and control. By testing the impact of fertilizer matrix on plant growth at different ratios, it is ensured that the fertilizer will not affect the nutrient supply required for normal growth of crops and maintain the health of soil and crops. The safety at each ratio is evaluated through field trials to ensure the long-term safety of the fertilizer in actual application and reduce the risks to the environment and non-target organisms.
[0038] Furthermore, when mixing the Lycoris radiata extract and the fertilizer matrix in S4, an inert filler and the Lycoris radiata extract are selected for premixing, and the inert filler is one of diatomaceous earth and talcum powder to help the Lycoris radiata extract to be evenly distributed. The premixed Lycoris radiata extract is micronized to make the particles finer and increase its surface area. After the treatment is completed, the fertilizer matrix is first added to the mixing device, and then the premixed Lycoris radiata extract is slowly added to the fertilizer matrix in batches and continuously stirred. The mixing time is 10-30 minutes. During the mixing process, pure water is sprayed inside the mixing device to wet the surface of the mixture so that the particles are easier to adhere to each other. Then, the vibration energy generated by the ultrasonic generator and the transducer is used to destroy the formed agglomerate structure to help the active ingredients to be better dispersed. After the final mixing is completed, the mixed medicinal fertilizer raw materials are poured into the interior of the screening equipment, and the residual large particles or agglomerates are removed by screening to ensure that the particle size of the final medicinal fertilizer raw materials is uniform.
[0039] Inert fillers help Lycoris radiata extract to be evenly distributed in the fertilizer matrix, ensuring that the active ingredients are evenly distributed throughout the product, improving the stability and reliability of the efficacy, avoiding the risk of drug damage caused by excessive local concentrations, and protecting crops from excessive exposure to alkaloids. Micronization makes the particles finer, increasing the surface area of the active ingredients, thereby increasing their diffusion rate and absorption efficiency in the soil. Finer particles are more easily absorbed by plant roots, enhancing the effectiveness of the fertilizer on crops. Water spraying and ultrasonic-assisted dispersion effectively prevent agglomeration between particles, ensuring good fluidity and uniformity of the mixture. Finally, large particles or lumps are removed by screening, ensuring uniform particle size of the fertilizer raw materials, which is conducive to uniform spreading during subsequent granulation and application. Efficient mixing equipment and technical means reduce the mixing time. The time required ranges from 10 to 30 minutes, which improves production efficiency. The optimized mixing process reduces unnecessary energy consumption and reduces production costs. The strict mixing process ensures the quality consistency of each batch of products and meets the requirements of agricultural production and market sales. Each link can be monitored and adjusted to ensure the repeatability and controllability of the production process. Uniform mixing reduces the toxicity risk that Lycoris radiata extract may bring, ensuring the safety of the product to humans and other non-target organisms. Lycoris radiata extract from natural sources combined with a scientific and reasonable mixing process reduces the use of chemical pesticides and reduces the risk of environmental pollution. The evenly distributed active ingredients can play a better role and improve the control effect on target pests. The nutrients provided by the fertilizer matrix support the healthy growth of crops. At the same time, the combination of medicine and fertilizer helps to improve the crop's resistance to diseases and insects.
[0040] Furthermore, the mixing equipment includes a mixing system, a feeding system, a spray wetting system, an ultrasonic assisted dispersion system, a humidity monitoring system, a discharging system and a self-cleaning system. The mixing system includes a mixing tank. A motor-driven multi-layer spiral stirring shaft is installed inside the mixing tank. The multi-layer spiral stirring shaft rotates and flips in three dimensions to achieve all-round mixing. The multi-layer spiral stirring shaft is made of corrosion-resistant and wear-resistant stainless steel. The feeding system includes a multi-point automatic feeding device and a precision feeder. The precision feeder weighs the raw materials to ensure the proportion of material addition. After weighing, the raw materials enter the multi-point automatic feeding device. The multi-point automatic feeding device is provided with a discharge port with independent control at different heights to feed the raw materials into multiple positions inside the mixing tank to improve the uniformity of the mixing process. The spray wetting system includes multiple micro nozzles installed on the mixing tank. The water pump draws pure water into the micro nozzles. The micro nozzles Pure water is converted into water mist and sprayed on the surface of the raw materials to moisten them. The ultrasonic assisted dispersion system includes an ultrasonic generator and a transducer. The transducer is installed on the surface of the mixing tank. The vibration energy generated destroys the formed agglomerate structure to help the active ingredients disperse better. The humidity monitoring system detects the humidity of the raw materials and transmits the detection signal to the controller. The controller controls the spray wetting system according to the preset humidity and the detected humidity. The discharging system includes a feeder and a feeding auger installed at the bottom of the mixing tank. The feeder transports the mixed drug and fertilizer raw materials in the mixing tank to the feeding auger. The feeding auger transports the drug and fertilizer raw materials directly to the screening equipment for automatic screening. The self-cleaning system includes an automatic spray flushing head installed on the mixing tank. The automatic spray flushing head can move up and down and rotate the angle to clean the inside of the mixing tank in all directions to facilitate subsequent raw material mixing.
[0041] The multi-layer spiral stirring shaft rotates and flips in three dimensions, achieving all-round mixing of materials and ensuring uniform distribution of active ingredients. The stirring shaft is made of corrosion-resistant and wear-resistant stainless steel, which extends the service life of the equipment and ensures long-term stable operation. The multi-point automatic feeding device and precision feeder ensure the accuracy of the material addition ratio, avoid human errors, and improve the consistency of product quality. The multi-point automatic feeding device is equipped with multiple independently controlled discharge ports, which can feed raw materials into different positions inside the mixing tank to further improve the mixing uniformity. The multiple micro nozzles installed on the mixing tank can convert pure water into fine water mist and spray it evenly on the surface of the raw materials. Increase the adhesion between particles and reduce agglomeration. The humidity monitoring system monitors the humidity of the raw materials in real time and automatically adjusts the spray volume according to the preset value to ensure the optimal wetting degree and avoid over-wetting or over-drying. The vibration energy generated by the ultrasonic generator and transducer destroys the formed agglomerate structure, helps the active ingredients to be better dispersed, and enhances the stability of the efficacy. The coordinated work of the spray wetting system and the ultrasonic assisted dispersion system further improves the dispersion effect and ensures that the active ingredients are evenly distributed throughout the mixture. The entire mixing process is uniformly managed by the controller, including feeding, spraying, ultrasonic operation and other links, realizing full-process automated control, reducing manual intervention and improving production efficiency.
[0042] Furthermore, the mixing equipment also includes a heating and cooling system, which includes a resistance heating element, a water-cooling coil, a temperature detector, a thermostat, a heat recovery device and a cooling fan. The resistance heating element and the water-cooling coil are installed in the tank interlayer of the mixing tank. The temperature detector and the thermostat detect the temperature of the raw materials. When the temperature is too low, the resistance heating element is started for heating. The resistance heating element is a number of electric heating rods distributed around. When the temperature is too high, the water-cooling coil and the cooling fan are started. The cooling medium flows inside the water-cooling coil to cool the raw materials. The cooling fan is installed outside the mixing tank to increase air flow and help cooling. The heat recovery device recovers heat from the cooling medium after absorbing heat to avoid energy waste.
[0043] The temperature in the mixing tank can be precisely controlled by the resistance heating element and the water cooling coil to ensure that the raw materials are kept within the optimal temperature range during the entire mixing process. For some temperature-sensitive Lycoris extract components, excessively high temperatures may cause them to degrade or inactivate. The introduction of the heating and cooling system can effectively avoid this situation. Appropriate temperature helps to improve the fluidity of the material and reduce agglomeration, thereby improving the mixing efficiency. Gentle heating can accelerate the dissolution process of the solvent for the active ingredients, promote their better dispersion into the fertilizer matrix, and improve the performance of the final product. Precise temperature control ensures the consistency of each batch of products and reduces product quality differences caused by temperature fluctuations. Appropriate cooling measures can quickly reduce the temperature after mixing is completed, prevent the impact of high temperature on the finished product, and extend the shelf life of the product. The heat recovery device can transfer the heat in the cooling medium after absorbing heat. The system can reuse the amount of energy, reduce energy waste, and reduce production costs. The cooling fan increases air flow, helps to quickly cool down, reduces cooling time, and further saves energy. When the temperature is too high, the water cooling coil and cooling fan are automatically started to cool down, preventing safety hazards caused by overheating. Stable temperature control also extends the service life of the equipment and reduces mechanical damage caused by excessively high or low temperatures. The system can flexibly adjust the speed and degree of heating and cooling according to different process requirements. It is suitable for various types of raw materials and formulas, enhances the versatility and adaptability of the equipment, and can ensure the stability of the internal temperature regardless of how the external ambient temperature changes, supporting all-weather uninterrupted production. The temperature detector and thermostat monitor and feedback temperature information in real time, and combine with the controller to realize automatic temperature adjustment, reducing manual intervention and improving production continuity and reliability.
[0044] Furthermore, the mixing equipment also includes a vacuum-assisted mixing system, which includes a vacuum pump, a feed inlet sealing valve, a discharge port sealing valve and a pressure sensor. The vacuum pump extracts air from the mixing tank to make it vacuum inside. The feed inlet sealing valve seals the feed inlet of the mixing tank. The discharge port sealing valve seals the discharge port of the mixing tank to prevent outside air from entering the mixing tank. The pressure sensor detects the vacuum pressure inside the mixing tank. When the set pressure is reached, the vacuum pump is turned off. By maintaining a vacuum environment during the mixing process, air can be effectively prevented from entering the material to form bubbles.
[0045] By extracting the air inside the mixing tank and maintaining a vacuum environment, air can be effectively prevented from entering the material to form bubbles, which is crucial to ensuring the uniform distribution of active ingredients and avoiding local concentrations that are too high or too low due to bubbles. Without air interference, the contact between materials is closer, which helps to improve the uniformity of mixing and ensure consistent quality of each batch of products. The vacuum environment reduces the presence of oxygen and reduces the risk of oxidation of sensitive ingredients in Lycoris radiata extract, extending the shelf life of the product and maintaining its efficacy. The sealed feed and discharge ports further prevent pollutants from the outside air from entering the mixing tank, ensuring product hygiene and safety. Under vacuum conditions, solvents can more easily penetrate into the solid particles, promoting the dissolution and dispersion of active ingredients and improving the quality of fertilizers. After removing air, the fluidity of the material is improved, reducing agglomeration, and making the mixing process smoother and more efficient. The mixing process under a vacuum environment reduces gas resistance, making it easier for materials to flow and mix, thereby shortening the mixing time and improving production efficiency. Combined with a pressure sensor to monitor the vacuum pressure in real time, the working state of the vacuum pump can be automatically adjusted according to actual conditions to ensure optimal mixing conditions.
[0046] Furthermore, the mixing equipment also includes a magnetization system, which is connected to the water inlet end of the spray wetting system, and magnetizes the water. The magnetization treatment changes the structure of water molecules, improves its permeability and wettability, and makes it better adhere to the surface of the material, thereby improving the mixing effect. The magnetization system includes a magnetic field generator, a liquid delivery pipeline and a control unit. The magnetic field is generated by an electromagnet. The electromagnet generates a magnetic field through an electric current. When water flows in the liquid delivery pipeline, it passes through the magnetized area. Under the action of the magnetic field, the water molecules and other molecules in the fluid are rearranged, causing the water molecule clusters to become smaller, thereby improving the solubility and permeability of the liquid. The control unit adjusts the current of the electromagnet to control the strength of the magnetic field.
[0047] The magnetization treatment changes the structure of water molecules, making the water molecule clusters smaller, improving their permeability and wettability, which helps water adhere better to the surface of materials, especially on relatively fine and easily agglomerated materials such as Lycoris radiata extract and fertilizer matrix. The improved wettability ensures that the water mist generated by the spray system can cover all material particles more evenly, reducing the problem of local uneven wetting and further improving the mixing effect. Magnetized water has a higher solubility and can more effectively dissolve active ingredients, especially those that are originally difficult to dissolve. This is crucial to ensure that active ingredients such as alkaloids in Lycoris radiata extract are fully dissolved and evenly distributed. The high permeability of magnetized water helps to break the agglomeration structure between materials, making it easier for active ingredients to be dispersed throughout the mixture. , enhancing the uniformity and stability of medicated fertilizer products. Due to the efficient wetting and dissolving ability of magnetized water, the contact between materials is closer, reducing the time required for mixing and improving production efficiency. A faster mixing process means reducing equipment operating time and energy consumption, reducing production costs. The application of magnetized water ensures the consistency of each batch of products and reduces product quality differences caused by uneven wetting or poor dissolution. Magnetized water treatment may help maintain the stability and activity of active ingredients, thereby extending the shelf life of the product. The efficient dissolving and penetration properties of magnetized water reduce water consumption and save water resources, which is in line with the concept of green production. The current of the electromagnet is accurately adjusted by the control unit, and the magnetic field strength can be flexibly adjusted according to actual needs to avoid unnecessary energy waste.
[0048] Furthermore, the mixing equipment also includes a multi-frequency vibration system, which is installed at the bottom of the mixing tank and provides vibration sources of different frequencies to help break up clumps and promote sufficient contact between materials. The multi-frequency vibration system includes a vibration table. The motor installed inside the vibration table generates vibration by rotating the eccentric mass block, so that the vibration table generates vertical or horizontal vibration movement. The frequency of the vibration is adjusted by changing the speed of the motor. The vibration is transmitted to the mixing tank through the base, so that the material in the mixing tank is affected by the vibration.
[0049] The vertical or horizontal vibration movement of the multi-frequency vibration system can effectively break up the agglomerate structure in the material and prevent the occurrence of large particles and agglomeration. This is especially important for fine particles such as Lycoris radiata extract that are easy to agglomerate. Vibration promotes full contact between materials, allowing the active ingredients to be more evenly distributed in the fertilizer matrix, improving the quality consistency of the final product. Vibration increases the collision and friction between materials, accelerates the mixing speed of materials, shortens the mixing time, and thus improves production efficiency. Multi-frequency vibration ensures that materials in every corner of the mixing tank are affected by vibration, reduces dead corners during the mixing process, and ensures comprehensive mixing of materials. Vibrations of different frequencies can be adjusted according to the characteristics of the material to help further refine the particles. Especially for those ingredients that are difficult to disperse, the dispersion effect is enhanced. Vibration helps the solvent to better penetrate into the solid particles, promotes the dissolution and dispersion of active ingredients, and improves the effect of fertilizers. Vibration reduces the static friction between materials, improves the fluidity of materials, makes the mixing process smoother, and reduces the wear of the stirring shaft and blades. Vibration can prevent the accumulation or blockage of materials in the mixing tank and maintain the good operation of the equipment. The vibration frequency can be adjusted by changing the speed of the motor. The vibration intensity can be flexibly adjusted according to the characteristics of different materials and the requirements of the mixing stage to ensure the best mixing conditions. Combined with the controller and sensor, the vibration frequency and intensity can be monitored in real time, and automatically adjusted according to the actual situation to achieve intelligent control.
[0050] Furthermore, the mixing equipment also includes a high shear force dispersion device, which is a high-speed shear head and is installed at the bottom of the multi-layer spiral stirring shaft. When the high-speed shear head rotates with the multi-layer spiral stirring shaft, a strong shear force will be generated to quickly break up large particles and clumps, and promote the uniform distribution of active ingredients. The high-speed shear head is composed of multiple independent shear units, each unit contains one or more groups of shear blades, and these units are evenly distributed along the circumferential direction to form a complete circular or polygonal structure. The spacing between adjacent shear units can be adjusted to adapt to raw materials of different particle sizes. A group of shear blades includes an outer blade and an inner blade. The outermost side of the outer blade is serrated, which is used to preliminarily break up large particles and clumps. The outermost side of the inner blade is also serrated, and the serrations are finer and sharper than those of the outer blade, which is used to further refine the material and ensure that the active ingredients are fully dispersed. The inclination angle of the outer blade and the inner blade is 30-60°.
[0051] The strong shear force generated when the high-speed shear head rotates with the multi-layer spiral stirring shaft can quickly break up large particles and lumps to ensure uniform distribution of materials. This is especially important for fine particles such as Lycoris radiata extract that are easy to agglomerate. The outer blades initially break up large particles and lumps, and the inner blades further refine the materials, forming a multi-stage crushing mechanism to ensure full dispersion of the active ingredients. Through the strong shear force and multi-stage crushing mechanism, the active ingredients can be more evenly distributed in the fertilizer matrix, improving the quality consistency of the final product, avoiding the risk of pesticide damage caused by excessive local concentration, and protecting crops from excessive exposure to alkaloids. The efficient crushing and dispersion process reduces the time required for mixing, thereby improving production efficiency. The multi-point layout of the shear head and the uniform distribution design along the circumferential direction ensure that the materials in the entire mixing tank can be affected by shearing, enhancing the mixing effect. The spacing between adjacent shear units can be adjusted according to the material characteristics to adapt to raw materials of different particle sizes, ensuring the best crushing and dispersion effects. The flexible adjustment capability enables the equipment to handle a variety of types of materials, enhancing its versatility and adaptability.
