Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine planting technology, specifically relating to a seedling raising device for planting traditional Chinese medicine. Background Technology

[0002] In the field of Chinese herbal medicine cultivation, seedling raising is a crucial step in ensuring the healthy growth of seedlings, and its quality directly affects the survival rate of transplanting and the yield and quality of medicinal parts.

[0003] However, traditional seedling containers are mostly enclosed on all sides or have irregular perforations, which has certain limitations in practical applications. During the growth of medicinal herb seedlings, the root systems are prone to "root coiling" and "root entanglement," which hinders the growth of the taproot and causes disordered lateral root distribution. This results in a reduction in root absorption area and decreased nutrient transport efficiency, especially for medicinal herbs such as Salvia miltiorrhiza, Astragalus membranaceus, and Ginseng, where the roots are the medicinal part. Furthermore, seedlings with coiled roots are easily broken during transplanting, causing mechanical damage, and the disordered root system struggles to adapt quickly to the new soil environment, leading to a prolonged recovery period. Therefore, there is an urgent need for a seedling raising device that can optimize the root growth environment to improve root development, increase transplant success rate, and enhance planting efficiency. Utility Model Content

[0004] To overcome the problems of root entanglement and tangling in the roots of medicinal herb seedlings caused by the closed or irregularly perforated structures of traditional seedling containers, this invention provides a seedling cultivation device for medicinal herbs. By incorporating root-guiding columns and rings within the seedling trough to guide orderly root growth, combined with drainage channels and a permeable layer, it avoids obstruction of the taproot and disorder of lateral roots, improves the root absorption area and nutrient transport efficiency, reduces mechanical damage to the roots during transplanting, shortens the seedling establishment period, and increases the transplant survival rate.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A seedling raising device for planting Chinese herbal medicines mainly includes a seedling trough, a partition plate, a root guide column, a root guide ring, a drainage trough, and a breathable layer. The seedling trough is a rectangular structure with an open top, and its interior is divided into several independent seedling units. Each seedling unit has a drainage hole at the bottom that penetrates the bottom surface of the seedling trough. The partition plate is set inside the seedling trough and isolates the seedling units from each other. The root guide column is vertically fixed at the center of the bottom of the seedling unit. The outer wall of the root guide column has multiple spiral protrusions evenly distributed along the axial direction. The top of the root guide column is set with a conical tip structure. The root guide ring is sleeved on the outside of the root guide column, and its inner wall and the outer wall of the root guide column form an annular gap with a width of 1 to 2 millimeters. The drainage trough is set at the bottom of the seedling trough and extends along its length. The bottom surface of the inner wall of the seedling trough is covered with a breathable layer, which is made of porous ceramic material.

[0006] The root guide post is connected to the bottom of the seedling unit by a thread. The bottom of the root guide post has an external thread, and the bottom of the seedling unit has an internal thread at the corresponding position. The root guide ring is fixed to the outside of the root guide post by a buckle. The buckle is located on both sides of the inner wall of the root guide ring. The end of the buckle has an elastic protrusion. The outer wall of the root guide post has a groove at the corresponding position. The elastic protrusion is embedded in the groove to achieve fixation.

[0007] The seedling trough has multiple ventilation holes on its side wall. The ventilation holes are arranged at equal intervals along the height of the seedling trough, with a diameter of 3 mm and a spacing of 10 mm. The ventilation holes are fitted with filter screens made of stainless steel.

[0008] The top edge of the seedling trough extends outward to form a flange, and the surface of the flange is provided with anti-slip texture. The seedling trough is installed on the seedling frame through the flange. The seedling frame consists of two parallel horizontal bars and a vertical bar connecting the two ends of the horizontal bars. The flange of the seedling trough is fixed to the horizontal bars with bolts.

[0009] The partition plate is coated with an antibacterial coating with a thickness of 0.1 mm to 0.2 mm. The seedling trough is made of high-strength polypropylene material. The air-permeable layer and the drainage trough are fixedly connected by an environmentally friendly silicone adhesive.

[0010] The beneficial effects of this utility model are: This invention, through the synergistic action of root guide columns and root guide rings, guides the main root to extend downwards and the lateral roots to expand horizontally, solving the problems of root "winding" and "entanglement". The partition plate avoids mutual interference between roots, while reducing mechanical damage to the roots during transplanting, shortening the seedling recovery period, and improving the transplant survival rate. The drainage trough and air-permeable layer structure ensures moderate moisture and smooth gas exchange in the root growth environment, further promoting healthy root development. The ventilation holes and filter structure ensure air permeability while preventing external pollution, improving the overall performance of the seedling device. Attached Figure Description

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] This utility model discloses a seedling raising device for planting traditional Chinese medicinal herbs. The device mainly includes a seedling trough 1, a partition plate 2, root guide columns 3, root guide rings 4, a drainage trough 5, and a breathable layer 6. The seedling trough 1 is a rectangular structure with an open top. Its interior is divided into several independent seedling units by the partition plate 2. The partition plate 2 is evenly distributed along the length of the seedling trough 1 and is fixedly connected to the inner wall of the seedling trough 1, forming multiple isolated spaces. Each seedling unit has a drainage hole 9 penetrating the bottom surface of the seedling trough 1, allowing excess water to drain naturally under gravity. The surface of the partition plate 2 is coated with an antibacterial coating, which evenly covers the outer surface of the partition plate 2. The coating thickness is controlled between 0.1 mm and 0.2 mm to ensure antibacterial effect without affecting the strength and durability of the partition plate 2. The root guide post 3 is vertically fixed at the center of the bottom of the seedling unit. Its bottom has external threads, while the corresponding position at the bottom of the seedling unit has internal threads. The two are fixed together by the threads. The top of the root guide post 3 has a conical tip structure with a height of 5 mm and a cone angle of 60 degrees, facilitating natural contact and downward extension of the seedling roots. Multiple spiral protrusions 31 are evenly distributed axially on the outer wall of the root guide post 3. The protrusions are 1 mm high and spaced 3 mm apart, with a semi-circular cross-section, guiding the main root to grow downwards in a predetermined direction. A root guide ring 4 is fitted onto the outside of the root guide post 3, forming a 1-2 mm wide annular gap between its inner wall and the outer wall of the root guide post 3, guiding the lateral roots to expand horizontally. The root guide ring 4 is fixed to the outside of the root guide post 3 by clips located on both sides of its inner wall. The clips have elastic protrusions 41 at their ends, and corresponding grooves 32 are formed on the outer wall of the root guide post 3. The elastic protrusions 41 are embedded into the grooves 32 for fixation. The root guide ring 4 is made of silicone material, which has a certain degree of elasticity and flexibility, and can expand appropriately according to the root growth, so as to avoid compressing the root system.

[0018] A drainage trough 5 is provided at the bottom of the seedling trough 1, extending along the length of the seedling trough 1. The drainage trough 5 has a trapezoidal cross-section and a bottom inclination angle of 5° to ensure rapid drainage of accumulated water. The bottom surface of the inner wall of the seedling trough 1 is covered with a breathable layer 6, made of porous ceramic material, with a thickness of 3 mm, a pore size of 0.5 mm, and a porosity of 30%. The breathable layer 6 is fixedly connected to the seedling trough 1 using an environmentally friendly silicone adhesive. The adhesive is 0.2 mm thick, and the bonding area covers the entire lower surface of the breathable layer 6, ensuring a strong and non-toxic connection.

[0019] Multiple ventilation holes 7 are provided on the side wall of the seedling tray 1. The ventilation holes 7 are evenly spaced along the height of the seedling tray 1, with a hole diameter of 3 mm and a hole spacing of 10 mm. A filter screen is embedded in each ventilation hole 7. The filter screen is made of stainless steel and is 0.3 mm thick. The outer edge of the filter screen fits tightly against the inner wall of the ventilation hole 7, requiring no additional fixing measures after installation. The ventilation holes 7 allow air to circulate freely while preventing external impurities from entering the seedling unit.

[0020] The top edge of the seedling trough 1 extends outward to form a flange 8, which is 20 mm wide. The surface of the flange 8 is provided with anti-slip texture, which consists of parallel straight protrusions with a height of 1 mm and a spacing of 5 mm, making it easy for operators to grip and carry. The seedling trough 1 is installed on the crossbar of the seedling frame via the flange 8. The seedling frame consists of two parallel crossbars and vertical bars connecting the two ends of the crossbars. The flange 8 of the seedling trough 1 is fixed to the crossbars with bolts to enhance the stability of the device.

[0021] The seedling tray 1 is made of high-strength polypropylene material with a thickness of 2 mm. Its corrosion resistance and anti-aging properties meet the requirements for long-term repeated use. The adhesive between the permeable layer 6 and the drainage trough 5 is environmentally friendly silicone, with a thickness of 0.2 mm. The adhesive area covers the entire lower surface of the permeable layer 6, ensuring a firm connection that is non-toxic and harmless. The filter screen inside the ventilation hole 7 is installed by pressing, with the outer edge of the filter screen tightly fitted to the inner wall of the ventilation hole 7, requiring no additional fixing measures after installation.

[0022] In practical applications, firstly, the seedling trough 1 is placed on the seedling rack, and the flange 8 is fixed to the crossbar with bolts to enhance the stability of the device. When seedlings are needed, an appropriate amount of seedling substrate is filled into each seedling unit, with a substrate thickness of 50 mm. Next, the Chinese herbal medicine seeds are sown on the surface of the substrate and covered with a thin layer of soil, with a thickness of 5 mm. During the seedling process, the taproot of the seedling will naturally come into contact with the conical tip of the root guide post 3 and extend downward along the spiral protrusion 31 on the outer wall of the root guide post 3. Lateral roots extend horizontally through the annular gap of the root guide ring 4, thus forming an orderly root distribution. When there is too much water in the seedling unit, the excess water is filtered through the air permeable layer 6 and flows into the drainage trough 5 through the drainage hole 9, and is discharged from the outlet at the lowest point of the drainage trough 5. The filter screen in the air vent 7 allows air to circulate freely while preventing external impurities from entering the seedling unit, further improving the air permeability of the root growth environment.

[0023] During transplanting, operators can easily move the seedling tray 1 by flipping the edge 8 and remove the seedlings along with the substrate. Due to the synergistic effect of the root guide column 3 and the root guide ring 4, the root system forms an orderly distribution during growth, reducing mechanical damage to the root system during transplanting and shortening the seedling recovery period.

[0024] This invention guides the main root downwards through the spiral protrusions 31 of the root guide column 3, and guides the lateral roots horizontally through the annular gaps of the root guide ring 4. Together, these two elements create an orderly root distribution, solving the problems of "root coiling" and "root entanglement" found in traditional seedling containers. The partition plate 2's isolation function prevents cross-interference between roots, and the antibacterial coating inhibits pathogen growth, thereby improving seedling survival rates. The drainage trough 5 and the breathable layer 6 ensure a suitable moisture level and smooth gas exchange in the root growth environment, further promoting healthy root development. The ventilation holes 7 and filter structure ensure breathability while preventing external contamination, further improving the overall performance of the seedling device.

[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
