Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] Please refer to Figure 1 , Figure 1 The present invention is a flowchart of the steps of preparing an insect repellent fertilizer mixed with Chinese herbal medicine extracts according to the first embodiment of the present invention.

[0031] The present invention provides a preparation method of a Chinese herbal medicine extract anthelmintic fertilizer, wherein the microporous matrix includes a metal microporous matrix, an inorganic microporous matrix and an organic microporous matrix, using the microporous matrix as a carrier, a variety of specific bacterial communities are attached and grown, and organic fertilizers are coordinated to fertilize in the soil, so that the specific harmful heavy metals in the soil can be processed, so that the harmful heavy metal elements are fixed in the microorganisms and are no longer absorbed by crops, thus eliminating the accumulation of heavy metals in crops. In addition, the present invention also provides organic fertilizers, which are sprinkled together with the microporous matrix in the field, and can provide nutrients for farmland and can provide nutrients for the microorganisms in the microporous matrix. In addition, the present invention further incorporates Chinese herbal medicine components (mainly Chinese herbal medicine residues) in the fertilizer, realizes anthelmintic treatment by the Chinese herbal medicine components (mainly the smell emitted by Chinese medicine), and can also effectively prevent disease and insect pests.

[0032] As one of the key points of the present invention, the preparation method of the microporous matrix is ​​as follows:

[0033] The molten titanium-containing blast furnace slag (temperature above 1480°C and below 1550°C) is rapidly cooled by cold water or a cold water solution (quenching liquid). The specific operation is: the molten titanium-containing blast furnace slag is transported to the water quenching device through the slag discharge ditch along a straight line (the slag discharge ditch is a straight line, the purpose of which is to improve the smoothness of the flow of the molten titanium-containing blast furnace slag), and the molten titanium-containing blast furnace slag is sprayed with high-pressure water at a temperature above 1.5 MPa (below 3 MPa) and a water temperature of 10°C to 25°C in the water quenching device (the lower the water temperature and the higher the water pressure, the smaller the particle size and volume of the titanium-containing blast furnace slag after cooling). The processing capacity of the molten titanium-containing blast furnace slag is 1.5 tons per minute. Calculated by mass fraction, the slag-to-water ratio is between 1:4 and 1:5. The amount of cooling water used is greater than that of the blast furnace slag, which can provide sufficient cooling, so that the molten titanium-containing blast furnace slag can be rapidly cooled into particles with a particle size between 5 and 8 mm. Due to the rapid cooling of the molten titanium-containing blast furnace slag, the slag particles will form a large number of micron-scale voids (presenting a honeycomb structure or a multi-pore interconnected structure), thereby forming a metal multi-porous matrix. During the above operation, ultrasonic generators are set at the water quenching device on both sides of the flow direction of the molten titanium-containing blast furnace slag (the ultrasonic generators are well waterproofed and high-temperature-resistant), and the internal voids of the slag particles are increased by ultrasonic action. Further, the ultrasonic generators are set in pairs, along the flow direction of the molten titanium-containing blast furnace slag, the spacing between the first pair of ultrasonic generators and the second pair of ultrasonic generators is N, the spacing between the second pair of ultrasonic generators and the third pair of ultrasonic generators is 2N, and the spacing between the third pair of ultrasonic generators and the fourth pair of ultrasonic generators is 3N. The number of pairs of ultrasonic generators does not exceed 5 pairs, and the value of N is not more than 30cm and not less than 5cm. In the selection of the metal multi-porous matrix, the present invention preferably uses a metal titanium multi-porous matrix, which can provide the trace element titanium to plants.

[0034] Select straw, stick etc. as raw material, carry out high temperature carbonization under nitrogen environment, thus obtain organic multi-microporous matrix.It should be noted that, the present invention needs to carry out crushing process to it first after obtaining raw material, makes raw material form the particle with particle diameter not less than 1cm and not more than 3cm, for straw generally it is chopped, for stick then it is cut into the tetrahedron with side length of 1.5cm to 2.0cm, or adopt crusher directly to carry out crushing to straw, stick etc., carry out high temperature carbonization again after raw material crushing process, thus form the organic multi-microporous matrix (in high temperature carbonization process, the moisture inside raw material and part organic matter can gasify thereby increase raw material volume in overflow process, and then after raw material carbonization, the volume of organic multi-microporous matrix can be slightly larger than raw material volume) that volume is not less than original particle volume.When straw or stick are carried out high temperature carbonization process, while producing granular carbon, also can produce a part of carbon dust, carbon dust can be used for other purposes.When using straw or stick as organic multi-microporous matrix raw material, organic matter can be provided for the growth of biological bacteria.

[0035] For inorganic multi-microporous matrix, the present invention selects zeolite particles, medical stone particles, volcanic rock particles or foamed ceramic particles for use, and particle diameter is between 0.3-0.5cm, and adopts vibrating screen to sieve to obtain inorganic multi-microporous matrix particles of suitable particle size. Specifically, adopt ball mill to grind and sieve after, particle diameter is 0.3-0.5cm. Zeolite particles and medical stone particles can provide trace elements.

[0036] In the above technical content, the present invention provides three methods for obtaining microporous matrices. After obtaining the three microporous matrices, three parts of an inorganic microporous matrix, three parts of an organic microporous matrix, and one part of a metal microporous matrix are mixed by volume and set aside. The microporous matrices are of various types (metallic, organic, and inorganic), and the bio-bacteria are introduced during field fertilization, thereby achieving safe and environmentally friendly remediation of heavy metal-contaminated soil. This remediation is also easy to implement, and the microporous matrices also provide the trace elements required by plants.

[0037] As one of the key points of the present invention, the biological bacteria selected by the present invention are commercially available Bacillus subtilis (Bacillus subtilis is widely used in agriculture. It can improve the disease resistance, cold resistance and drought resistance of crops, promote crop growth and increase yield. It has good effects on preventing and controlling diseases of crops such as rice, wheat, peanuts, tomatoes, peppers, soybeans, corn, etc., especially for wheat powdery mildew, ergot, sheath blight, etc. The prevention and control effect is better. In addition, Bacillus subtilis can also degrade harmful substances and convert organic waste into organic fertilizer), Bacillus megaterium (Bacillus megaterium is used as a production strain of biological pesticides due to its efficient spore production ability and stress resistance. It can produce various beneficial metabolites, such as insecticides, fungicides and plant growth promoters, helping farmers reduce the use of chemical pesticides and achieve the goal of green agriculture. Bacillus megaterium can decompose organic matter and provide the nutrients required by plants, improve The texture and structure of the soil. The active metabolites of Bacillus megaterium can also promote the growth and stress resistance of crops, and improve crop yield and quality. Most importantly, Bacillus megaterium can degrade organic pollutants and heavy metals in the soil, reducing the impact of environmental pollution on crop growth. At the same time, it converts nitrogen in the air into a nitrogen source that can be used by crops through biological nitrogen fixation, realizing the effective use of nitrogen fertilizer and environmentally friendly agricultural development), green Trichoderma (in practical applications, Trichoderma can germinate and reproduce rapidly in the soil, colonize the rhizosphere soil of plants, inhibit the infection of pathogens on crops, prevent plant death and rotten seedlings caused by soil-borne diseases and continuous cropping diseases caused by continuous cropping obstacles, and at the same time, Trichoderma can improve the rhizosphere soil flora structure of crops, creating a good soil ecological environment for crop root growth and resistance to adversity) and round brown nitrogen-fixing bacteria (can absorb nitrogen elements in the air, and then fix them in the soil to supply crops). One or any combination of multiple. The above-mentioned strains can be used for soil remediation and promote vegetation growth. In addition, the present invention also utilizes As-III type oxidizing bacteria for the remediation of arsenic-contaminated soil and Mucor circinelloides for the remediation of lead-contaminated soil. The existing technical solutions are used for the cold storage, activation, inoculation, etc. of the biological bacteria. After obtaining the activated biological bacteria, the present invention inoculates it into a liquid culture medium, and then soaks the mixed microporous matrix into the liquid culture medium, and cultures it under a constant temperature (between 20°C and 22°C) for 5-15 days. It should be noted that the present invention requires pretreatment before soaking the microporous matrix into the liquid culture medium. The pretreatment operation of the microporous matrix is: soak the microporous matrix in clean water, and then stir it. During the stirring process, ultrasonic cleaning is preferably performed, and the maintenance time is 2-4 hours. This not only allows clean water to fully enter the voids (gaps) of the microporous matrix, but also allows the microporous matrix to be cleaned. After the microporous matrix is ​​cleaned, it is fished out and transferred to the liquid culture medium for subsequent soaking operations.Because the microporous matrix is ​​thoroughly stirred and ultrasonically treated during the cleaning phase, its internal micropores are filled with clean water. This accelerates the exchange of the liquid culture medium with the clean water within the micropores, allowing the biological bacteria in the liquid culture medium to fully enter the microporous matrix. After the immersion culture is completed, natural drying is carried out. Care should be taken to prevent air and dust contamination during the drying process. The most preferred drying environment is sterile hot air drying in a sterile workshop.

[0038] After drying the microporous matrix, it can be directly mixed into fertilizer as a fertilizer component, or the microporous matrix can be further coated with a wax layer or a colloidal culture medium (e.g., agar culture medium). The wax layer has a thickness of 1-2 mm, and the colloidal culture medium has a thickness of 3-5 mm. The colloidal culture medium needs to be dried. The present invention preferably uses a colloidal culture medium. After the microporous matrix (the culture medium coated with the colloidal culture medium) is spread on the field, the colloidal culture medium will melt after irrigation, making the surrounding soil environment more nutritious and enabling the biological bacteria to better activate and proliferate in the field soil.

[0039] The present invention is a fertilizer that uses composted organic fertilizer raw materials such as chicken manure and sheep manure, followed by drying and granulation, to produce granular fertilizer with a particle size of 0.2-0.6 cm. By volume, 10-15 parts of fertilizer are mixed with 1 part of a microporous matrix. The fertilizer used in the present invention can be any commercially available organic fertilizer.

[0040] As one of the key points of the present invention, the invention also utilizes Chinese herbal medicine for insect repellency and repellency. This involves adding a Chinese herbal extract, allowing the extract to be absorbed by zeolite, and then producing a fertilizer together. The Chinese herbs and the zeolite that has absorbed the herbal extract release their herbal aroma, which insects in the field dislike and will stay away from. This repellent effect can be achieved during crop cultivation. Regarding the selection of Chinese herbs, the flavors of Chinese herbs disliked by soybean borers primarily include those of chinaberry leaves, bitter almonds, astragalus, and Toosendan fruit. These herbs contain ingredients that have inhibitory or killing effects on soybean borers. The insecticidal ingredients in chinaberry leaves are primarily azadirachtin and its derivatives, which effectively inhibit the feeding and reproduction of soybean borers. Bitter almonds contain the toxic ingredient amygdalin hydrocyanate, which can kill soybean borers. Astragalus contains an ingredient that inhibits insect reproduction and has a killing effect on soybean borers. Toosendan fruit contains ingredients such as meliaphenol and melialdal, which can also inhibit insects. The present invention can select one of the above ingredients or any combination of them for decoction alone, or can cooperate with a Chinese medicine factory or an important clinic to select the medicinal residues containing the above ingredients as raw materials for re-decoction.

[0041] Specifically, the present invention has two solutions:

[0042] 1. Select fresh (unused) materials, cook them under high pressure (1.2-1.4 atmospheres) for 1-1.5 hours, filter the slag water, soak the zeolite and medical stone particles in filtered water (Chinese herbal medicine extract) and stir (by volume, the ratio of filtered water to zeolite and / or medical stone is 1:0.5), the soaking time is 5-12 hours, the soaked zeolite and medical stone are taken out and dried, the filtered water is dried and powdered, the filtered medicinal residues are crushed into powder, the above-mentioned zeolite, medical stone, filtered water powder and medicinal residue powder are mixed (for the convenience of description, the mixture of zeolite, medical stone, filtered water powder and medicinal residue powder is limited to an anthelmintic combination) and added to the fertilizer, and the ratio of fertilizer to anthelmintic combination is 20:1-40:1 by mass fraction.

[0043] 2. Select used Chinese herbal medicines, boil them in water under normal pressure for 0.5-1.5 hours, filter the residue water to obtain the medicinal residues and the Chinese herbal medicine extract, and soak the Chinese herbal medicine extract in zeolite and / or medical stone for absorption and standby use. Dry the medicinal residues and grind them into 80-100 mesh medicinal residue powder, then directly sprinkle it on crops to form a medicament that has a repellent or killing effect on soybean borers. Alternatively, according to the mass fraction, 0.5 parts of the medicinal residue powder can be mixed with 80-100 parts of fertilizer (the above-mentioned fertilizer containing a microporous matrix) for use.

[0044] In the first scheme, selected Chinese herbal medicine raw materials are soaked in water at a mass fraction of 2:3, and then high-pressure steaming is performed. After the residue and water are separated, one part of the filtered water is soaked with 0.5 parts of zeolite and / or medical stone according to a volume ratio. The zeolite and / or medical stone are then dried, and the remaining soaking water is dried and powdered. All the Chinese herbal medicine residues are crushed, and the zeolite and / or medical stone, the soaking water-supported powder, and the crushed herbal medicine residues are mixed to form an anti-parasitic combination for use.

[0045] These herbal insecticides are pollution-free, safe, and reliable, making them an effective biological control method for soybean borer. The flavors of Chinese herbs disliked by soybean borer primarily include chinaberry leaves, bitter almonds, astragalus, and toosendan fruit. These herbs contain ingredients that inhibit or kill the borer. The above formulation can produce a formulation that repels or kills soybean borer. These herbal insecticides are pollution-free, safe, and reliable, making them an effective biological control method for soybean borer.

[0046] The present invention provides a method for preparing an insect repellent fertilizer mixed with a Chinese herbal medicine extract. In the present invention, the method for preparing an insect repellent fertilizer mixed with a Chinese herbal medicine extract comprises the following steps: Step 1, preparing a multi-microporous matrix for standby use. In Step 1, the present invention uses a multi-microporous material to prepare it into a granular form for standby use. The multi-microporous matrix has a large number of micropore gaps distributed inside, which can provide a larger growth and attachment area for biological bacteria; Step 2, selecting target biological bacteria and preparing a liquid culture medium to culture the target biological bacteria. In Step 2, the present invention selects two different types of bacteria, one of which is beneficial to the growth of crops and the other is capable of treating heavy metal-contaminated soil. The two bacterial species for repair are beneficial to the growth of crops and soil repair; step three, soaking the microporous matrix in a liquid culture medium so that the liquid culture medium fully enters the internal gap of the microporous matrix, and the microporous matrix is ​​used to provide an attachment surface for the growth of biological bacteria, so that the microporous matrix can form bacteria-containing particles, which is convenient for the release of biological bacteria in the field; step four, drying the microporous matrix and mixing it with fertilizer, and spreading the bacteria-containing microporous matrix and fertilizer together into the field, completing the release of biological bacteria in the process of field fertilization, thereby realizing safe and environmentally friendly repair of heavy metal contaminated soil, and the repair is easy to implement.

[0047] As can be seen from the above, the present invention provides a method for preparing an insect repellent fertilizer mixed with Chinese herbal extracts. These preparation methods include two methods: 1. Using particles with a multi-microporous structure as a matrix to absorb the Chinese herbal extract and then mixing it with fertilizer; 2. Selecting used Chinese herbal medicine residues containing chinaberry leaves, bitter almonds, astragalus, and / or toosendan fruits for future use; drying and pulverizing the Chinese herbal medicine residues and using them directly as an insect repellent or mixing them into fertilizer to prepare a fertilizer with insect repellent properties. In either of these two methods, the present invention utilizes Chinese herbal medicines as insect repellents and insecticides. Chinese herbal medicines as insect repellents and insecticides have the advantages of being pollution-free, safe, and reliable. In particular, the present invention specifies that the Chinese herbal medicines primarily include chinaberry leaves, bitter almonds, astragalus, and / or toosendan fruits. These Chinese herbal medicines contain ingredients that have inhibitory or killing effects on soybean borers, thus forming a medicament that has a repellent or killing effect on soybean borers, representing an effective biological control method for soybean borers.
