Description

Technical Field

[0001] This invention relates to the field of continuous cropping obstacles in cultivation, and particularly to a device for helping Chinese medicinal herbs overcome continuous cropping obstacles. Background Technology

[0002] Continuous cropping of Chinese medicinal herbs can easily produce various autotoxic substances, which can inhibit the growth of plants of the same species or family, leading to continuous cropping obstacles. Common autotoxic substances include phenolic acids, organic acids, fatty acids, alcohols, aldehydes, esters, and other compounds. These substances affect plant growth and development through multiple pathways, such as inhibiting root nutrient absorption, reducing photosynthetic efficiency, interfering with intracellular protein and DNA synthesis, and altering soil microbiota, thereby exacerbating continuous cropping obstacles. Traditional techniques to address continuous cropping obstacles typically involve excavating soil from the field and transporting it to a factory for autotoxic substance removal. However, this involves large soil volumes, increasing transportation costs and lengthy processing times. Therefore, to maintain normal crop growth, it is necessary to develop a device for overcoming continuous cropping obstacles in Chinese medicinal herb cultivation to address these issues.

[0019] The following detailed description of a device for overcoming continuous cropping obstacles in the cultivation of Chinese medicinal herbs, provided by the present invention, is provided through specific embodiments. Example 1 When Chinese medicinal herbs are continuously cropped, they are prone to producing a variety of autotoxic substances. These substances can inhibit the growth of plants of the same species or family, leading to continuous cropping obstacles.

[0020] Common autotoxic substances and their effects include: First: It produces phenolic acid compounds, such as benzoic acid, cinnamic acid, ferulic acid, coumaric acid, p-hydroxybenzoic acid, vanillic acid, syringic acid, etc. Phenolic acids can inhibit the absorption of nitrogen, calcium, potassium and other ions by roots, affecting root growth and development; reduce the efficiency of plant photosynthesis, reduce chlorophyll content, and affect plant growth and development; interfere with the synthesis of proteins and DNA in plant cells, affecting normal cell function; phenolic acids can inhibit the growth of beneficial microorganisms and promote the proliferation of harmful microorganisms, leading to an imbalance in the soil microbial community and further exacerbating continuous cropping obstacles.

[0021] Second: It produces organic acids, such as citric acid, malic acid, and oxalic acid. The accumulation of organic acids can lower the pH value of the soil, increase soil acidity, and affect the absorption of nutrients by plants. The increased solubility of aluminum ions in acidic soil can be toxic to plant roots and inhibit root growth. It can also reduce the availability of micronutrients such as calcium and magnesium in the soil, thus affecting the normal growth of plants.

[0022] Third: Fatty acids such as erucamide and long-chain fatty acids; High concentrations of fatty acids can inhibit seed germination and affect seedling growth; reduce the growth of roots, stems, and leaves in seedlings, affecting plant biomass; affect the activity of enzymes in plants, such as superoxide dismutase (SOD) and peroxidase (POD), increase malondialdehyde (MDA) content, and lead to cell membrane damage.

[0023] Fourth: alcohols, aldehydes, and esters such as ethanol, acetaldehyde, and ethyl acetate; Alcohols and aldehydes can damage cell membrane integrity and affect normal cell physiological functions; these substances can inhibit plant growth through multiple pathways, affecting photosynthesis and respiration; the accumulation of these substances in the soil can alter the soil's chemical properties, affecting soil fertility and microbial activity.

[0024] Fifth: Other compounds such as dioctyl terephthalate, antioxidant 2246, etc.; Compounds such as dioctyl terephthalate and antioxidant 2246 can significantly inhibit the growth of plant seedlings at high concentrations; these compounds can also alter the soil microbial community, promote the proliferation of harmful microorganisms, and further exacerbate continuous cropping obstacles.

[0025] This invention provides, for example Figures 1-7 The device shown is designed to help overcome continuous cropping obstacles in the cultivation of Chinese medicinal herbs. It can overcome continuous cropping obstacles, reduce the accumulation of autotoxic substances, improve the soil environment, and increase plant growth and yield.

[0026] Using the above-mentioned device to help overcome continuous cropping obstacles in the cultivation of Chinese medicinal herbs, and in conjunction with the following treatment preparations, the implementation of the operation to overcome continuous cropping obstacles is as follows: Soil conditioning is applied to address the different autotoxic substances produced, such as: 1. For phenolic acid compounds, a mixture of biochar, lime, microbial inoculants, and wood ash is used; Biochar, with its rich porous structure and large specific surface area, can adsorb phenolic compounds in the soil, reducing their inhibitory effect on plants. Biochar can also improve the physical properties of the soil, increasing its aeration and water retention capacity. Applying lime in appropriate amounts can neutralize soil acidity and increase soil pH, thereby reducing the solubility and bioavailability of phenolic compounds. Lime can also provide calcium ions to promote the growth of plant roots. Adding specific microbial agents, such as Bacillus subtilis and Bacillus amyloliquefaciens, can promote the proliferation of beneficial microorganisms in the soil. These microorganisms can decompose phenolic acid compounds and reduce their inhibitory effect on plants. Wood ash contains abundant minerals such as potassium and calcium, which can neutralize soil acidity, increase soil pH, and provide the nutrients needed by plants, promoting plant growth.

[0027] II. For organic acids, use lime (mainly calcium carbonate), slaked lime (mainly calcium hydroxide), compost, and green manure for treatment: Lime can neutralize organic acids in the soil, increase the soil pH, and improve the acidic environment of the soil. Limestone powder can also provide calcium ions, which promote the growth of plant roots.

[0028] Quicklime has strong alkalinity and can quickly neutralize organic acids in the soil and increase the soil pH value. When using it, care should be taken to control the amount used to avoid excessive use leading to soil alkalization.

[0029] Applying compost can increase the organic matter content in the soil, improve soil structure and fertility, and the microorganisms in compost can decompose organic acids, reducing their inhibitory effect on plants.

[0030] Planting green manure crops (such as legumes, pumpkins, etc.) and incorporating them into the soil can increase the organic matter content of the soil and improve its physical properties. The microorganisms in green manure can decompose organic acids and reduce their inhibitory effect on plants. Continuous cropping typically involves sowing in late April to early May, with maturity in July and August. Pumpkins can be planted in August and September; simply incorporate them into the soil after the pumpkin seedlings have grown. This avoids the problem of yield reduction caused by continuous cropping obstacles. Soybeans can also be planted in August and September, and incorporate them into the soil after the soybean seedlings have grown.

[0031] 3. For fatty acids, activated carbon, biodegradable agents, humic acid, and microbial agents are used for treatment; Activated carbon has a strong adsorption capacity, which can adsorb fatty acids in the soil and reduce their inhibitory effect on plants. Activated carbon can also improve the physical properties of the soil and increase the soil's aeration and water retention capacity. Using specific biodegradable agents, such as lipases, can promote the decomposition of fatty acids in the soil and reduce their inhibitory effect on plants. Biodegradable agents can decompose fatty acids into harmless small molecules, thereby reducing their toxicity to plants. Humic acid has good adsorption and exchange capacity. It can adsorb fatty acids in the soil and reduce their inhibitory effect on plants. Humic acid can also improve the physical properties of the soil and increase its water retention and aeration. Adding specific microbial agents, such as Pseudomonas and Bacillus, can promote the proliferation of beneficial microorganisms in the soil. These microorganisms can decompose fatty acids and reduce their inhibitory effect on plants.

[0032] For alcohols, aldehydes, and esters, hydrogen peroxide, activated carbon, microbial agents, and wood ash are used for treatment; Hydrogen peroxide has strong oxidizing properties and can oxidize alcohols, aldehydes, and esters in the soil, breaking them down into harmless small molecules, thereby reducing their inhibitory effect on plants. When using it, attention should be paid to controlling the concentration to avoid oxidative damage to plants. Activated carbon can adsorb alcohols, aldehydes, and esters in the soil, reducing their inhibitory effect on plants. Activated carbon can also improve the physical properties of the soil, increasing its aeration and water retention capacity. Adding specific microbial agents, such as yeast and acetic acid bacteria, can promote the proliferation of beneficial microorganisms in the soil. These microorganisms can decompose alcohols, aldehydes, and esters, reducing their inhibitory effect on plants. Wood ash contains abundant minerals such as potassium and calcium, which can neutralize soil acidity, increase soil pH, provide nutrients needed by plants, and promote plant growth. Wood ash can also absorb alcohols, aldehydes, and esters in the soil, reducing their inhibitory effects on plants.

[0033] For other compounds, activated carbon, microbial agents, humic acid, lime, and other methods are also used for treatment.

[0034] Therefore, overcoming the obstacles of continuous cropping requires soil improvement. This can be achieved by adding biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, hydrogen peroxide, etc., to the soil and mixing these substances thoroughly with the soil. If necessary, compost and green manure can also be used to further improve the soil and increase the yield of continuous cropping.

[0035] refer to Figure 1 and Figure 7 As shown in the figure, this embodiment of a device for overcoming continuous cropping obstacles in the cultivation of Chinese medicinal herbs includes a transfer box 1, a feeding box 2, a crushing hopper 11, and a digging shovel 14 arranged in sequence. A mixing box 10 is installed below the transfer box 1. One side of the mixing box 10 is mounted on an agricultural machine 32, which can be an electric vehicle or a gasoline vehicle and can operate in the field. During use, the digging shovel 14 rotates to dig the soil from the ground into the crushing hopper 11. The soil is broken up in the crushing hopper 11 and enters the feeding box 2 along the crushing hopper 11. In the feeding box 2, it is mixed with substances such as biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide. After the mixed soil enters the transfer box 1, it is discharged into the mixing box 10 for secondary mixing. The soil after secondary mixing is directly discharged, thus realizing soil restoration and avoiding the phenomenon of continuous cropping obstacles in cultivation.

[0036] It should be noted that the shovel 14 is mounted on the second rotating shaft 12. A connecting frame 33 is provided on one side of the agricultural machinery 32. The two ends of the second rotating shaft 12 are rotatably connected to the connecting frames 33 on both sides. A second motor 13 is mounted on one of the connecting frames 33. The rotating shaft of the second motor 13 is fixedly connected to the second rotating shaft 12. Three shovels 14 are provided, equidistantly distributed along the axis of the second rotating shaft 12, arranged in a circular array of three shovels as a group. Multiple groups are distributed along the length of the second rotating shaft 12. The shovel 14 has an arc-shaped plate structure. A second vertical rod 16 is fixedly installed on the concave arc surface of the shovel 14, and a first vertical rod 15 is fixedly installed on the convex arc surface of the shovel 14. Multiple first vertical rods 15 and second vertical rods 16 are provided, and multiple first vertical rods 15 and second vertical rods 16 are arranged alternately. When the second motor 13 drives the second rotating shaft 12 to rotate, the second vertical rod 16 on the shovel 14 first inserts into the soil, digging out the soil on the one hand, and initially breaking up the soil on the other hand. The broken up soil is collected in the inner arc surface of the shovel 14. Although the shovel 14 rotates and the agricultural machinery 32 moves forward, the soil is moved into the crushing bucket 11.

[0037] When the shovel 14 rotates to a position close to the crushing bucket 11, the first vertical bar 15 can be inserted into the unexcavated soil to divide the soil. When the next set of shovels 14 digs the soil, multiple second vertical bars 16 divide the soil again. The first vertical bar 15 and the second vertical bar 16 can be combined to divide the soil into multiple pieces, which are finally dug out by the shovel 14.

[0038] In summary, by setting a first vertical bar 15 and a second vertical bar 16 on the excavator 14, and with the positions of the first vertical bar 15 and the second vertical bar 16 being staggered, the soil can be pre-divided and secondary-divided before being excavated into the crushing bucket 11. This not only reduces the difficulty of subsequent soil dispersal, but also reduces the energy consumption generated when excavating large chunks of soil from the ground.

[0039] refer to Figure 1 , Figure 4 and Figure 5As shown, the crushing bucket 11 has an inclined trough structure, with its lower end inclined towards the digging shovel 14. A pusher plate 5 and a stop bar 6 are installed in the crushing bucket 11. The pusher plate 5 is detachably connected to the third rotating shaft 18. Sliding grooves 19 are provided on both sides of the crushing bucket 11. A ball bearing 17 is rotatably connected to the end of the third rotating shaft 18. The ball bearing 17 is slidably disposed in the sliding groove 19 along its height direction. One end of the third rotating shaft 18 is connected to the rotor on the third motor 20. The crushing bucket 11 is connected by a shaft. An L-shaped support slide 22 is fixedly installed on the side of the crushing bucket 11 near the third motor 20. A spring 23 is fixedly installed on the L-shaped support slide 22. A support slide plate 21 is fixedly connected to the upper end of the spring 23. The support slide plate 21 is slidably installed along the height direction of the L-shaped support slide 22. The support slide plate 21 is supported on the bottom of the third motor 20. The two ends of the baffle 6 are fixedly connected to the inner walls of both sides of the crushing bucket 11. Multiple baffles 6 are provided and distributed along the height direction of the crushing bucket 11.

[0040] During operation, the soil entering the crushing bucket 11 is squeezed through the baffle 6 and horizontally divided by multiple baffles 6, which can separate the soil into granular state. When the third motor 20 is started, it drives the push plate 5 to rotate, which moves the soil along the surface of the crushing bucket 11 towards the addition box 3.

[0041] Further reference Figure 1 As shown, when the pusher plate 5 rotates clockwise, it pushes the soil along the crushing hopper 11 towards the adding box 3. Because the soil is squeezed between the bottom of the pusher plate 5 and the upper surface of the crushing hopper 11, it generates a large resistance that affects soil conveying and increases the working energy consumption of the third motor 20. However, in this invention, based on the spring 23, ball bearing 17 and sliding groove 19, when the pusher plate 5 is blocked by the soil, the pusher plate 5, the third rotating shaft 18, the ball bearing 17, the support slide plate 21 and the third motor 20 will move upward to avoid this resistance. During the rotation of the pusher plate 5, it conveys the soil that is easier to convey from the upper position, which saves the working energy consumption of the third motor 20, improves the soil conveying efficiency, and does not cause the soil to be pressed and stuck to the surface of the crushing hopper 11.

[0042] It should be noted that, as the shovel 14 continuously delivers new soil into the crushing bucket 11 during its rotation, even if the push plate 5 rises to a certain extent along the height direction, it can still deliver a sufficient amount of soil during its rotation. Furthermore, as the agricultural machinery 32 moves forward and generates a shaking effect, the soil below the push plate 5 will also shift its position, and there will be no excessive soil being compacted between the push plate 5 and the crushing bucket 11.

[0043] refer to Figure 1 , Figure 2and Figure 6 As shown, a feed chute 4 communicating with the inside of the crushing hopper 11 is provided at the lower end of the feeding box 2. When the pusher plate 5 pushes the soil, the soil enters the feeding box 2 through the feed chute 4. A auger blade 26 is provided inside the feeding box 2, with multiple auger blades 26 distributed along the width direction of the feeding box 2. A first motor 9 is installed on the upper surface of the transfer box 1, and a first rotating shaft 8 is fixedly connected to the shaft of the first motor 9. The first rotating shaft 8 is distributed along the length direction of the feeding box 2, moving through the transfer box 1 and extending into the inside of the feeding box 2. The auger blades 26 are fixedly connected to the first rotating shaft 8. When the first motor 9 starts, the auger blades 26 rotate, drawing soil into the feeding box. Soil in box 2 is continuously conveyed upwards. An addition box 3 is fixedly installed on the upper surface of the feeding box 2. A box cover 7 is set on the top of the addition box 3. When the box cover 7 is opened, a mixture of biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, hydrogen peroxide and other substances can be added to the addition box 3. A discharge port 25 is set at the bottom of the addition box 3. A flow control valve 24 is set in the discharge port 25. The mixture can continuously and quantitatively enter the feeding box 2 through the flow control valve 24. During the upward conveying process in the feeding box 2, the soil is not only further refined, but also fully mixed with the mixture. After these mixtures are mixed with the soil, they can repair the soil and overcome the obstacles of continuous cropping.

[0044] refer to Figures 1 to 7 As shown, the transfer box 1 is fixedly connected to the feeding box 2. A mixing box 10 is connected to the lower part of the transfer box 1. The mixing box 10 has a cylindrical structure and an annular chamber 28 inside. A rotating mechanism 29 is installed in the annular chamber 28. Multiple sets of rotating mechanisms 29 are distributed along the axis of the mixing box 10. An outlet 31 is provided on the upper part of the side of the mixing box 10 away from the feeding box 2. The outlet 31 is connected to the interior of the annular chamber 28. A baffle 30 is provided between the lower end of the transfer box 1 and the annular chamber 28 and the outlet 31. The baffle 30 is fixedly connected to the inner wall of the annular chamber 28. When the soil enters the annular chamber 28, the multiple sets of rotating mechanisms 29 rotate clockwise, which can transport the mixture and soil clockwise along the annular chamber 28 and discharge them directly into the field from the outlet 31. The baffle 30 is used to prevent the soil and mixture that have just entered the annular chamber 28 from being discharged from the outlet 31 without being mixed again.

[0045] The rotating mechanism 29 includes blades, a power shaft, and a fourth motor. The fourth motor is installed outside the mixing box 10. The power shaft and the rotating shaft of the fourth motor are fixedly connected. The blades are fixedly installed on the power shaft. When the fourth motor is started, it can drive the blades to rotate through the power shaft, thereby conveying the soil and mixture inside the annular chamber 28.

[0046] Furthermore, the inner wall of the feeding box 2 in this invention is provided with an electric heating plate 27. After the electric heating plate 27 is turned on, the soil is heated to a certain extent. For example, heating can decompose the organic matter in the soil and release some substances that help the soil aggregate, thereby improving the aggregate structure of the soil, increasing the porosity and aeration of the soil, which is beneficial to the growth of plant roots and the activity of soil microorganisms. Generally speaking, low temperature heating (such as around 60°C) is more gentle on the improvement of soil structure and will not cause excessive damage to the soil.

[0047] This embodiment describes a device for overcoming continuous cropping obstacles in the cultivation of Chinese medicinal herbs. This device works in the field and directly adds substances such as biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide to the soil, eliminating the need to transport the soil to a factory for processing. This effectively reduces processing costs, is highly efficient, and does not affect continuous planting.

[0048] This embodiment uses the above-mentioned operating method of the device for helping Chinese medicinal herb cultivation overcome continuous cropping obstacles, including the following steps: The device, which uses traditional Chinese medicine cultivation to overcome continuous cropping obstacles, is used in the field to turn over the soil, add a mixture to the soil and mix it evenly, and then transport the soil back to the field. The mixture includes biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide.

[0049] Preferably, the mixture is encapsulated using an enclosure, the enclosure comprising: a capsule shell; The mixture is compressed into sheets, rods, or granules using a blending or pressing method. The mixing method includes: mixing a mixture of a container, biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide to form a mixture A. In mixture A, the container, biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide are mixed together. The mixture of biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide exists on the surface of the container and inside the formed container. The mixed-pressing method includes: mixing a mixture of a container, biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide to form a mixture A. In mixture A, the container, biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide are intermingled and compacted into a tablet shape using a tablet-making machine. The mixture of biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide exists on the surface of the container and inside the formed container.

[0050] Preferably, the containment body comprises: a mixture of gelatin and gum arabic; or a chitosan-sodium alginate composite material; or a polylactic acid-glycolic acid copolymer. The containment body for accommodating the mixture, such as a capsule shell, contains a mixture of biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, hydrogen peroxide, etc., which is then introduced into the soil. As the capsule breaks, the mixture gradually acts on the soil, sustainably remediating it and reducing the degradation of soil remediation effectiveness due to soil erosion. The containment body allows the mixture to act slowly and continuously on the soil, addressing not only existing autotoxic substances but also continuously generated ones, achieving long-term soil remediation effects. The use of simple processes such as fusion and mixing to manufacture the containment body reduces the complexity of the process, making the soil remediation method easier to implement and promote. Furthermore, the remediation materials used are all environmentally friendly, harmless to the soil and ecological environment, meeting the requirements of sustainable development. It can be used in the field without transporting the soil to a factory for processing, effectively reducing processing costs and increasing efficiency.

[0051] Furthermore, a mixture of biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, hydrogen peroxide, and other substances can be compacted into flakes, rods, or granules to allow the mixture to act slowly and continuously on the soil, making full use of existing tablet and capsule drug concepts.

[0052] It should be noted that the capsule shell can be made of gelatin-gum arabic composite material, chitosan-sodium alginate composite material, or polylactic acid-glycolic acid copolymer, etc. Among these, gelatin and gum arabic mixed and formed into microcapsules through a coagulation method, exhibit good biocompatibility and biodegradability, enabling the slow release of the internal mixture, making it suitable for soil remediation. Chitosan and sodium alginate possess good film-forming properties and biocompatibility, and can be formed into microcapsules through ionic cross-linking. This material can slowly degrade in soil, releasing the internal remediation substances. For example, some studies have used chitosan-sodium alginate microcapsules to encapsulate microbial agents, allowing for slow release in the soil, thus improving the survival rate of microorganisms and the remediation effect.

[0053] It should also be noted that since the mixture of biochar, lime, microbial agent, wood ash, slaked lime, activated carbon, humic acid, hydrogen peroxide and other substances in this invention is a powder material, the inclusion body can be made by the mixing and pressing method.

[0054] For example, a mixture of gelatin and gum arabic is mixed with a mixture of biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, hydrogen peroxide, etc., to form mixture A. In mixture A, gelatin, gum arabic, and remediation substances, including biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, hydrogen peroxide, etc., are intermingled. The remediation substances exist on the surface of the gelatin and gum arabic and inside the formed containment. When the remediation substances are mixed into the soil, part of the remediation substances can directly remediate the soil, while the other part can continuously remediate the soil. The mixing method designed for soil remediation is more suitable for soil remediation and simplifies the process. Because the mixture is compacted, the speed at which the mixture integrates into the soil will be reduced. Depending on the degree of compaction, the mixture can act on the soil for up to 2-3 months. The mixing and compaction method designed for soil remediation is more suitable for soil remediation and achieves the goal of continuous remediation.

[0055] This embodiment describes a device for overcoming continuous cropping obstacles in the cultivation of Chinese medicinal herbs. Through the collaboration of multiple components, the soil is deeply mixed with materials for treating continuous cropping obstacles in the field to achieve functional regulation. The device specifically uses a mixture of substances such as biochar, lime, microbial agents, wood ash, slaked lime, activated carbon, humic acid, and hydrogen peroxide to address the problems existing in the soil due to continuous cropping obstacles. It can effectively reduce the accumulation of autotoxic substances, improve the soil environment, thereby overcoming continuous cropping obstacles and improving plant growth and yield.
