Description

TECHNICAL FIELD

[0001] The present application relates to the field of forestry production, in particular, relates to a seedling raising device with ventilation effect. BACKGROUND

[0002] Seedling raising is an important link in agricultural, horticultural and forestry production, which can help plants germinate and grow in the best environment, so as to achieve the goal of efficient production. Many plants such as vegetables, fruit trees, grain and oil crops, flowers, etc. need to be cultivated through the seedling raising stage in the cultivation process to ensure the healthy growth of seedlings, improve the survival rate, and facilitate management and transplanting.

[0003] During the seedling raising process, it is very important to maintain the flow of air. Ventilation can regulate temperature and humidity, provide fresh air, enhance the supply of carbon dioxide, and promote photosynthesis and healthy growth of plants. If ventilation is poor, the humidity in the seedling raising environment may be too high, leading to rapid reproduction of mold, bacteria and pests, which seriously affects the growth of seedlings. High humidity environment also inhibits transpiration, making the soil or substrate too wet, causing root oxygen deficiency. In low oxygen environment, the root system cannot breathe normally, and the metabolic function is hindered, resulting in rotting. High humidity and low air flow provide breeding conditions for pathogenic bacteria such as pythium and fusarium, which invade the fragile root tissue and further aggravate the rotting problem.

[0004] That is, good ventilation is needed during seedling raising to promote air circulation and oxygen supply to the root system, prevent disease occurrence, and ensure the healthy growth of seedlings. Generally, air vents are provided on the wall of the seedling hole to enhance the air convection between the inside and outside of the seedling hole, thereby improving the air flow in the seedling hole. However, the soil particles falling into the seedling hole will block the air vents on the seedling hole, resulting in poor ventilation of the seedling device, which makes the root system prone to rot and is not conducive to the healthy growth of seedlings. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide a seedling raising device with ventilation effect to solve the problem of poor ventilation caused by the blockage of air vents by soil particles.

[0006] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] The present application provides a seedling raising device with ventilation effect, which comprises a seedling plate, a plurality of seedling holes arranged in an array are provided on the seedling plate, the upper edge of the seedling hole is located in the plane of the seedling plate, the hole bottom of the seedling hole is located on the lower side of the seedling plate, the middle of the hole bottom is higher than the edge, and the hole bottom is in a convex shape, a small hole is provided on the hole bottom, and a partition plate is fixedly arranged on the inner wall of the seedling hole, and the partition plate is not in contact with the hole bottom.

[0008] When in use, the soil and seeds are placed on the partition in the seedling hole, and the small holes in the bottom of the hole are used to pass air into the seedling hole, so that a stable air convection is formed inside and outside the seedling hole. This convection can maintain a continuous air flow around the root system, providing sufficient oxygen to prevent the root system from rotting due to lack of oxygen. The partition can initially block the soil particles from falling and block the small holes in the bottom of the hole; at the same time, the smaller soil particles falling from the partition fall to the bottom of the hole. Due to the fact that the middle of the hole bottom is high and the edge is low, the falling soil particles can roll along the convex hole bottom to the edge of the hole bottom, that is, they can roll to the space between the edge of the hole bottom and the sidewall of the seedling hole under the action of gravity, thereby avoiding blocking the small holes for ventilation on the hole bottom, so as to ensure that the small holes on the hole bottom remain unblocked and maintain good ventilation performance for a long time. In addition, the convex hole bottom also increases the surface area of the hole bottom, which can be provided with more small holes to improve the ventilation effect.

[0009] At the same time, an air retention area is formed between the hole bottom and the partition, and the air entering the seedling hole from the small holes in the hole bottom is retained in this area. The air flow speed in the retention area is smaller than that outside the small holes. When the external air flow speed is large, it will quickly take away the water on the surface of the root system, causing the seedling to lack water. In this way, the setting of the retention area not only avoids the problem of rapid evaporation of water on the surface of the root system due to too fast air flow near the root system, but also avoids the problem of easy rotting of the root system caused by poor air flow, which is helpful for the healthy growth of the seedling.

[0010] Further, the hole diameter of the middle small hole in the hole bottom is smaller than the hole diameter of the edge small hole in the hole bottom. The hole diameter of the middle small hole in the hole bottom is smaller, mainly for ventilation, and the hole diameter of the edge small hole is larger, mainly for discharging accumulated water, soil particles, etc. The holes on the edge provide a discharge channel for the accumulated soil particles. When the soil particles accumulate to a certain amount, especially after pressure is formed at the lowest hole position, the soil particles can be discharged from the seedling hole through the larger hole diameter of the edge. In addition, there is often excess water during the seedling process, which accumulates at the low-lying part of the hole bottom and forms mud water after mixing with the soil particles. Due to the strong flowability of water, the mud water can take part of the smaller soil particles out of the seedling hole during flow, promoting the discharge of soil particles.

[0011] Further, the middle region of the partition is higher than the edge region of the partition; the partition is in a mesh structure. The partition is in a convex shape, the convex of the middle region increases the air gap between the partition and the bottom of the hole, i.e. the retention region, thereby forming a relatively spacious ventilation channel, so that the air flowing into the hole from the small hole of the bottom can flow more concentratedly and freely, further promoting the circulation of air in the seedling hole, while avoiding the accumulation of moisture due to poor ventilation at the bottom of the hole. Due to the mesh structure of the partition, air can easily pass through the mesh holes into the seedling hole, while soil particles are effectively blocked by the mesh holes to prevent direct clogging of the small hole. In addition, the convex of the middle region also reduces the ventilation obstruction caused by excessive accumulation of soil particles on the surface of the partition, so that the mesh hole remains unobstructed at all times, thereby ensuring the persistence and stability of the ventilation effect.

[0012] Further, the upper end of the seedling hole is small in size, and the lower end is large in size. The smaller upper opening can effectively reduce the evaporation of the upper layer of water, thereby helping to maintain the stability of the humidity in the seedling hole and avoiding the problem of dryness of the root caused by excessive loss of water. The larger size of the lower end provides more space for the full stretch of the root system; it also provides more space for the air flow on the lower side, improving the breathing capacity and growth efficiency of the root. The wide lower opening can reduce the risk of soil particles blocking the small hole at the bottom of the hole, ensuring the unobstructed ventilation path, thereby maintaining the convection effect of the air in the seedling hole and preventing the accumulation of moisture, reducing the risk of root rot.

[0013] Further, the seedling device further comprises a bottom plate, and recesses parallel to each other are arranged on the bottom plate, the direction of the recesses is parallel to the direction of the rows or columns in which the seedling holes are arranged, the water guide groove is perpendicular to the direction of the recesses, and one end of the recesses is in communication with the water guide groove. The recesses guide the excess water into the water guide groove, which is then discharged. The recess structure also forms an air space between the bottom plate and the seedling holes, enhancing the overall ventilation performance of the seedling device and providing more sufficient oxygen supply for the root system to promote the healthy growth of the seedlings.

[0014] Further, the width of the recess is smaller than the width of the bottom of the hole, and the distance between adjacent recesses is equal to the distance between adjacent seedling holes. In this way, the bottom of the seedling hole can be placed on both sides of the recess, providing good support; at the same time, the space between the recess and the seedling hole provides a channel for air flow, keeping the air flow unobstructed.

[0015] Further, the depth of the recess near one end of the water guide groove is greater than the depth of the recess away from the other end of the water guide groove. The excess water can flow from the end of the recess with smaller depth to the end with greater depth, and finally collect in the water guide groove.

[0016] Further, the seedling board is placed on the bottom plate, and the lower surfaces of the two sides of the seedling board are provided with protruding positioning strips, and the corresponding positions of the two sides of the bottom plate are provided with positioning grooves; the protruding positioning strips and the positioning grooves are inserted together. The protruding positioning strips on the two sides of the seedling board and the positioning grooves at the corresponding positions of the bottom plate are inserted together, so as to ensure the stable connection of the seedling board and the bottom plate, prevent the seedling board from sliding or shifting during use, and improve the overall firmness and reliability of the seedling device. The seedling hole is arranged just above the groove to ensure the drainage and ventilation effects and improve the seedling efficiency and quality.

[0017] Further, the cross-sectional shape of the protruding positioning strip and the cross-sectional shape of the positioning groove are both triangular; the depth of the positioning groove is greater than or equal to the depth of the groove near the water guide groove. The protruding positioning strip and the positioning groove are both triangular in cross section, which can provide a more secure insertion effect, prevent the seedling board from sliding or separating from the bottom plate during use, and improve the stability of the device. The depth of the positioning groove is greater than or equal to the depth of the groove near the water guide groove, which ensures that the drainage function of the groove is not affected, and at the same time ensures that the seedling board and the bottom plate are closely fitted, which helps to optimize the drainage and ventilation effects, and is convenient for installation and disassembly, and improves the overall use performance.

[0018] Further, one handle is fixedly arranged at each end of the seedling board, the handle is inverted U-shaped, and the two lower ends of the handle are fixed to the two sides of the seedling board. It is convenient for the seedling personnel to move the seedling board.

[0019] Compared with the prior art, the beneficial effects of the present application are:

[0020] (1) Firstly, the partition plate plays a role in preliminarily blocking soil particles, so that larger soil particles are difficult to fall off, and the small holes on the hole bottom for ventilation are prevented from being blocked by large-size soil particles; the middle of the hole bottom is higher than the edge, and when smaller-size soil particles fall on the hole bottom, the soil particles will roll along the surface of the hole bottom to the edge under the action of gravity, and will not block the small holes on the hole bottom, so that the air circulation inside and outside the seedling hole is ensured, and the root system is prevented from rotting.

[0021] (2) The partition plate and the hole bottom form an air storage area, when the air flow speed outside the small hole is large, the air flow speed in the storage area is relatively small, which can buffer and adjust the air entering the seedling hole. This low-speed airflow can avoid the rapid evaporation of water on the root surface caused by too fast air flow, prevent the seedling from being limited in growth due to water shortage, and further improve the ventilation effect.

[0028] In order to make the implementation process of the utility model more clearly, the following will be combined with the drawings to be described in detail.

[0029] The utility model provides a kind of seedling device with ventilation effect, as Figure 1 As shown, the device includes seedling plate 10, seedling plate 10 is provided with multiple arrayed seedling holes 11, each seedling hole 11 can cultivate seedling. The both ends of seedling plate 10 are fixedly provided with one handle 15 respectively, handle 15 is inverted U shape, the two lower ends of handle 15 are fixed to the both sides of seedling plate 10, and it is convenient to grip and carry. As Figure 2 As shown, the upper edge of seedling hole 11 is located in the plane of seedling plate 10, and the hole bottom of seedling hole 11 is located on the lower side of seedling plate 10. The middle of hole bottom is higher than the edge, and is convex. Small hole 13 is provided on the hole bottom, and small hole 13 is used for ventilation, so that the air inside and outside seedling hole 11 is exchanged;As Figure 3As shown, the diameter of the small hole 13 in the middle of the bottom of the seedling hole is smaller than that of the small holes 13 at the edge of the bottom. The size of the small hole is 1-3 mm, and the size of the large hole is 4-8 mm. The holes at the edge help to drain excess water and fallen soil particles. This design utilizes the fluidity of water and the gravity of soil particles. Through the difference in hole size and structural design, it achieves the effect of dynamically cleaning soil particles, while maintaining good ventilation and drainage in the seedling hole 11, providing a good basic environment for the healthy growth of seedlings. This not only improves the self-cleaning ability of the seedling hole 11, but also reduces the need for manual maintenance. The small holes can also be distributed in the central circular area, and the large holes can be distributed in the outer ring area. In this way, the large holes in the surrounding ring area can drain more water and soil particles. This is suitable for seedlings that require frequent and large amounts of watering during the seedling process or for seedlings with rich root systems that are prone to soil particle shedding during growth, such as fast-growing trees like poplar and willow, fruit trees like apple, pear, and citrus, and landscaping seedlings like boxwood and azalea.

[0030] The partition 12 is fixedly installed on the inner wall of the seedling hole 11. The partition 12 does not contact the bottom of the hole, and the distance between the partition 12 and the bottom of the hole is greater than 5mm. The middle area of ​​the partition 12 is higher than the edge area, forming a raised shape. The partition 12 has a mesh structure. The partition 12 can be a mesh plastic board, PVC mesh board, honeycomb plastic board, breathable foam board, non-woven fabric, etc., to facilitate air passage. The roots of the seedlings can pass through the partition 12. The mesh size of the partition 12 is 2-5mm, which can block large soil particles without hindering the growth of the seedling roots. Preferably, the upper part of the seedling hole 11 is smaller and the lower part is larger; generally, the upper part of the seedling hole 11 is 1.5-5cm and the lower part is 3-15cm. The specific size can be adjusted according to the actual situation. If multiple seedlings need to be cultivated in one seedling hole 11, the size of the seedling hole 11 can be larger. The smaller upper portion reduces evaporation, while the larger lower portion provides ample space for root growth. This design is suitable for seedlings with high humidity requirements and rich root systems, such as medicinal herbs like Coptis chinensis and ginseng, tea trees, dawn redwoods, and bald cypress. The larger lower portion also helps cultivate a more developed root system, enhancing its ability to adapt to the new environment after transplanting. This significantly improves the survival rate of transplanted seedlings and optimizes the overall seedling cultivation process and subsequent planting success rate.

[0031] The seedling raising device of this application also includes a base plate 20, such as Figure 4 As shown, the base plate 20 has parallel grooves 21, and the seedling holes 11 are placed on the grooves 21. The grooves 21 serve to provide ventilation and drainage. The direction of the grooves 21 is parallel to the direction of the rows or columns in which the seedling holes 11 are arranged. The water guide channel 22 is perpendicular to the direction of the grooves 21, and one end of the grooves 21 is connected to the water guide channel 22. The water in the grooves 21 collects in the water guide channel 22 and is then discharged.

[0032] The width of the groove 21 is less than the width of the bottom of the seedling hole, and the distance between adjacent grooves 21 is equal to the distance between adjacent seedling holes 11. Preferably, the width of the groove 21 is greater than the distance between the lowest holes 13 on both sides of the bottom of the seedling hole, so that the drained water can directly enter the groove 21 and will not be directly discharged onto the surface of the bottom plate 20. Furthermore, the depth of the groove 21 near the water guide trough 22 is greater than the depth of the end away from the water guide trough 22, forming a height difference to facilitate water flow into the water guide trough 22. Compared with directly tilting the bottom plate 20, the method of this application can ensure that the seedling holes 11 are on the same horizontal plane, so that the growth environment of each seedling hole 11 is as similar as possible. Otherwise, under the action of gravity, the water is unevenly distributed in the seedling holes 11, causing the seedlings near the upper side to lack water and grow poorly; if used for experimental research, it is difficult to ensure the uniformity of variables, and the results are unreliable. The cross-sectional shape of the groove 21 can be as follows: Figure 5 The rectangle shown can also be an inverted triangle, wider at the top and narrower at the bottom. The wider top helps collect more water and prevents it from overflowing into other parts of the seedling device, while the narrower bottom concentrates the water flow, allowing it to flow quickly and drain rapidly from the groove 21. The inverted triangle structure also creates an air circulation channel within the groove 21. The groove 21 on the base plate 20 connects to the small holes 13 at the bottom of the seedling holes 11, allowing air to flow smoothly and further improving the overall ventilation performance of the seedling device. This provides sufficient oxygen to the seedling roots, promoting healthy growth.

[0033] To facilitate the placement of the seedling board 10 and the base plate 20 by nursery workers, raised positioning strips 14 are provided on the lower surfaces of both sides of the seedling board 10, and corresponding positioning grooves 23 are provided on both sides of the base plate 20. Both the raised positioning strips 14 and the positioning grooves 23 are perpendicular to the water guide channel 22. The seedling board 10 is placed on the base plate 20, and the raised positioning strips 14 and the positioning grooves 23 are inserted together. The depth of the positioning groove 23 is greater than or equal to the depth of the groove 21 near the end of the water guide channel 22. The cross-sectional shape of the raised positioning strip 14 and the positioning groove 23 are both triangular, and the apex angle of the triangle of the raised positioning strip 14 is smaller than the apex angle of the triangle of the positioning groove 23. The coincidence of their vertices ensures high positioning accuracy, making it easier for nursery workers to insert the raised positioning strip 14 into the positioning groove 23. To ensure safety, the apex angle of the triangle of the raised positioning strip 14 is greater than 45°, making it relatively non-sharp and avoiding potential dangers.

[0034] The application optimizes the structural design of the seedling raising device, improves the ventilation effect, and effectively avoids the blockage of the small holes 13 by soil particles. The bottom of the seedling hole 11 is designed with a raised middle and a lowered edge, which guides the soil particles to roll to the edge area by gravity, preventing the particles from gathering above the air vent small holes 13. The small holes 13 are designed with different diameters, the small holes 13 in the middle area are mainly used for ventilation, and the small holes 13 in the edge area are used for drainage and particle removal. This division ensures the dual functions of ventilation and drainage. The partition plate 12 adopts a mesh structure, which can block larger particles of soil from entering the hole bottom, while allowing air, water, and roots to pass through, keeping the ventilation smooth. The partition plate 12 is raised in the middle, forming a gap with the hole bottom, providing a buffer space for air circulation, enhancing air convection effect, effectively controlling flow rate, avoiding rapid airflow causing excessive water evaporation, and protecting the root humidity environment. The overall design combines the concepts of soil particle gravity movement, air circulation path optimization, and self-cleaning, reducing blockage and maintenance requirements, providing a good ventilation and growth environment for seedlings, and helping to improve seedling raising efficiency and seedling health.

[0035] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
