Description

Technical Field

[0001] The invention belongs to the technical field of germination boxes, and particularly relates to a variable temperature germination box for Hainan yellow rattan tissue culture. Background Art

[0002] Hainan yellow rattan seeds have a certain degree of dormancy, the seed shell is relatively hard, and the embryo development inside the seed is relatively slow. It is easily affected by environmental factors (such as temperature, humidity, light, etc.), resulting in a low germination rate. The variable temperature germination box can break the dormancy period of seeds and promote seed germination by simulating the temperature change conditions of Hainan yellow rattan seeds in the natural environment (usually the temperature difference between day and night). Factors such as temperature control and humidity regulation in the variable temperature box can provide a stable and suitable environment, which helps to improve the speed and quality of seed germination. Through the application of the variable temperature germination box, it can systematically provide a suitable temperature change cycle, so that Hainan yellow rattan seeds can complete germination in a relatively short time, thereby improving the germination rate of seeds. Hainan yellow rattan, as an important fast-growing forest species, plays an important role in improving the ecological environment, providing wood resources, and promoting the development of forestry economy. Improving its reproduction and cultivation efficiency through technical means can not only increase the planting area and wood production, but also play a positive role in improving forest resource management and ecological restoration capabilities.

[0003] The seed coat of Hainan yellow rattan is usually thick and uneven, which leads to uneven water absorption and gas exchange process of seeds in the variable temperature germination box. Although the variable temperature germination box can regulate temperature and humidity, for seeds with uneven seed coat surface, water absorption in some areas may not be sufficient, thus affecting the overall germination rate of seeds. Some seeds may not be able to effectively break through the seed coat, resulting in incomplete or slow germination. Moreover, the unevenness of the seed coat will also lead to insufficient oxygen supply in the variable temperature germination box, affecting the normal growth of the embryo. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a variable temperature germination box for Hainan yellow rattan tissue culture.

[0005] The technical solution adopted to solve the above technical problems is: a variable temperature germination box for Hainan yellow rattan tissue culture, comprising a box body, a plurality of heat dissipation holes are opened through both sides of the box body, and the plurality of heat dissipation holes are symmetrically arranged, support feet are fixedly connected to the corners of the bottom surface of the box body, and a germination promotion mechanism is arranged inside the box body;

[0006] The germination promotion mechanism includes two slide rails, the two slide rails are fixedly connected to the inside of the box body, the two slide rails are slidably connected to a movable plate on the top, and the slide rails limit the movable plate, a connecting column is fixedly connected to the center of the bottom surface of the movable plate, and the other end of the connecting column is fixedly connected to a cross slide, a through groove is provided on one side of the cross slide, two ends of the cross slide pass through a sliding connection limit frame, the limit frame is fixedly connected to the box body, and the limit frame limits the cross slide, and a gap is set between the cross slide and the box body.

[0007] The above technical solution helps to simulate slight vibrations or wind in the natural environment, so that the roots of the plants can grow in a uniform direction. Especially in the tissue culture process of Hainan yellow rattan, the normal development of the root system is crucial to the later cultivation. Through horizontal shaking, the roots can get a more even supply of water and nutrients, which helps better development and prevents the problem of excessively concentrated root growth.

[0008] Furthermore, a circular plate is provided in the gap between the cross slide and the box body, the circular plate is rotatably connected to the box body, a sliding rod is fixedly connected to the side of the circular plate away from the box body, the sliding rod is located on the side of the eccentric part of the circular plate, and the sliding rod is located in the through groove, the sliding rod is slidably connected to the cross slide, a motor is installed on one side of the bottom end surface of the box body, the output end of the motor is rotatably connected to the box body, and the through end of the motor is fixedly connected to the circular plate.

[0009] Through the above technical solution, horizontal reciprocating shaking can promote slight flow of the culture solution, avoid excessive nutrients in the culture medium from being deposited in certain places, resulting in uneven nutrition and affecting plant growth. Through shaking, the nutrients in the culture medium can be more evenly distributed to the roots of each plant, helping to ensure that the plants get adequate nutrition supply.

[0010] Furthermore, a plurality of fixed rods are fixedly connected to the top surface of the movable plate, a top plate is fixedly connected between the other ends of the plurality of fixed rods, a slide groove is opened through the middle of the top plate, an electric push rod is installed on the top surface of the box body, the telescopic end of the electric push rod is slidably connected to the box body, the through end of the electric push rod is located in the slide groove, and the through end of the electric push rod is slidably connected to the top plate, and the through end of the electric push rod is fixedly connected to a round block.

[0011] Through the above technical solution, horizontal shaking can simulate weak vibrations in the natural environment, such as wind or slight vibrations of the soil. This stimulation helps to enhance the resistance of plants and promote healthier growth of plants. During the tissue culture process, plants grow in a relatively static environment. The lack of this external stimulation may cause the plants to be too weak. Horizontal shaking can simulate this stimulation of the natural environment and help increase the physiological activity and resistance of plants.

[0012] Furthermore, several of the fixing rods are passed through and fixedly connected with a first placing basket, two second placing baskets are respectively arranged on the top and bottom of the first placing basket, the fixing rods are passed through and slidably connected with the second placing basket, and a U-shaped frame is fixedly connected with the top surface of the second placing basket located on the top of the first placing basket, a limiting groove is provided on the top of the U-shaped frame, the round block is located inside the limiting groove, and the round block is slidably connected to the U-shaped frame, the U-shaped frame limits the round block, and the telescopic end of the electric push rod is engaged with the limiting groove.

[0013] Through the above technical solution, the fluidity of the air can be increased, which helps to evenly distribute the temperature and humidity, and avoid excessive differences in temperature and humidity, which may cause poor plant growth in certain areas.

[0014] Furthermore, the first placing basket is cross-rotatingly connected with a first connecting plate and a second connecting plate on both sides, and the first connecting plate is rotatably connected to the second connecting plate at the center, and the second placing basket located on the top of the first placing basket has the same settings on both sides as the first placing basket, and the first connecting plate and the second connecting plate located on both sides of the second placing basket are alternately rotatably connected with the first connecting plate and the second connecting plate located on both sides of the first placing basket, and the second placing basket located at the bottom of the top plate and the second placing basket located at the top of the movable plate are rotatably connected with a third connecting plate and a fourth connecting plate on both sides, and one end of the third connecting plate is rotatably connected to one end of the fourth connecting plate, and the other ends of the third connecting plate and the fourth connecting plate are rotatably connected to the first connecting plate and the second connecting plate respectively.

[0015] Furthermore, the first placement basket and the second placement basket are provided with a plurality of placement grooves, and the top of the placement groove is a square structure, and the bottom of the placement groove is a round hole.

[0016] Through the above technical solution, by adjusting the distance between the baskets, the air flow in the germination box can be improved. The larger interval can effectively avoid air stagnation, enhance the air circulation in the box, and prevent local moisture accumulation and lack of oxygen.

[0017] Furthermore, a plurality of heating rods are installed on one side of the interior of the box, an integrated power supply is installed on the back of the box, the integrated power supply is electrically connected to the heating rods, two door panels are hinged on the side of the box away from the integrated power supply, the two door panels are arranged in opposite directions, an observation window is opened in the middle of the door panel, and a handle is provided on one side of the observation window, and the handle is welded and fixed to the door panel.

[0018] Through the above technical solution, appropriate spacing can give the roots and leaves of each plant better development space, avoiding uneven growth due to insufficient space. The seedlings can be distributed more evenly and develop more healthily. In addition, the temperature and humidity distribution in the germination box can be optimized so that plants in each area can enjoy a suitable environment and avoid local excessive moisture or dryness.

[0019] The beneficial effects of the present invention are as follows: (1) The present invention drives the round block to move by an electric push rod. Since the round block is engaged with the U-shaped frame, the U-shaped frame moves simultaneously with the telescopic end of the electric push rod, thereby driving the second placement basket at the bottom of the bottom top plate to move along the linear direction of the fixed rod, and under the joint action of the third connecting plate and the fourth connecting plate, the second placement baskets on both sides of the first placement basket move in separate or opposite directions, thereby changing the distance between the first placement basket and the second placement basket, and the space can be adjusted according to the needs of Hainan yellow rattan at different growth stages. The space demand of seedlings is relatively small in the early growth stage, but as the roots and stems and leaves grow, their demand for space gradually increases. Adjusting the distance between the baskets can effectively avoid overcrowding, ensure that each plant has enough space to grow, promote the expansion and healthy development of the root system, and reduce competition between plants; (2) The present invention drives the round plate to rotate by a motor, so that the slide bar slides in the through groove, and at the same time The movable cross slide slides in the limit frame, and when the slide rod rotates one circle, the cross slide moves in the opposite direction, and the circular plate rotates continuously, so that the cross slide performs linear reciprocating motion in the limit frame. Under the action of the connecting column, the movable plate performs linear reciprocating motion on the slide rail synchronously, and when the movable plate performs linear reciprocating motion, the telescopic end of the electric push rod moves back and forth in the slide groove of the top plate. At the same time, the round block moves simultaneously in the limit groove of the U-shaped frame to adapt to the moving trajectory of the movable plate, so that the seeds placed in the basket perform horizontal linear reciprocating motion, which can help to distribute the water in the culture medium more evenly and prevent root rot or disease caused by water accumulation. Shaking helps to evenly penetrate water and prevent seeds and seedlings from depositing on the surface of the culture medium, reducing the occurrence of water accumulation areas. Horizontal shaking helps to simulate slight vibrations or wind in the natural environment, so that the roots of plants grow in a uniform direction. BRIEF DESCRIPTION OF THE DRAWINGS

The germination promotion mechanism includes two slide rails 11, and the two slide rails 11 are fixedly connected to the inside of the box body 1. A moving plate 12 is slidably connected to the top of the two slide rails 11, and a plurality of fixed rods 13 are fixedly connected to the top surface of the moving plate 12. The plurality of fixed rods 13 penetrate and are fixedly connected to a first placement basket 19, and the first placement basket 19 is cross-rotatably connected to a first connecting plate 21 and a second connecting plate 22 on both sides. The proper spacing can allow the roots and leaves of each plant to have better development space, avoiding uneven growth due to insufficient space, and the seedlings can be more evenly distributed and grow more healthily. In addition, the temperature and humidity distribution in the germination box is optimized so that the plants in each area can enjoy a suitable environment to avoid local excessive moisture or dryness. The first connecting plate 21 is rotatably connected to the center of the second connecting plate 22, and the two sides of the second placement basket 20 located on the top of the first placement basket 19 have the same settings as the two sides of the first placement basket 19. The first connecting plate 21 and The second connecting plate 22 is alternately rotatably connected to the first connecting plate 21 and the second connecting plate 22 located on both sides of the first placing basket 19, and the second placing basket 20 located at the bottom of the top plate 14 and the second placing basket 20 located at the top of the movable plate 12 are rotatably connected on both sides with the third connecting plate 23 and the fourth connecting plate 24. By adjusting the distance between the placing baskets, the air flow in the germination box can be improved. The larger interval can effectively avoid air stagnation, enhance the air flow circulation in the box body 1, and prevent local moisture accumulation and lack of oxygen, and one end of the third connecting plate 23 is rotatably connected to one end of the fourth connecting plate 24.

[0031] like Figure 4-Figure 8The third connecting plate 23 and the fourth connecting plate 24 are rotatably connected to the first connecting plate 21 and the second connecting plate 22 respectively. Two second placing baskets 20 are respectively arranged at the top and the bottom of the first placing basket 19. The first placing basket 19 and the second placing basket 20 are provided with a plurality of placing grooves 31. The horizontal reciprocating shaking can promote the slight flow of the culture solution to avoid excessive nutrients in the culture medium from being deposited in certain places, resulting in uneven nutrition and affecting plant growth. Through shaking, the nutrients in the culture medium can be more evenly distributed to the roots of each plant, which helps to ensure that the plants obtain sufficient nutrition supply. The top of the placing groove 31 is a square structure, and the bottom of the placing groove 31 is a round hole. The fixing rod 13 and the second placing basket 20 penetrate and slide. The top surface of the second placement basket 20 located on the top of the first placement basket 19 is fixedly connected with a U-shaped frame 17. A limiting groove 18 is provided on the top of the U-shaped frame 17. The round block 16 is located inside the limiting groove 18. Horizontal shaking can simulate weak vibrations in the natural environment, such as slight vibrations of wind or soil. This stimulation helps to enhance the resistance of plants and promote healthier growth of plants. In the tissue culture process, plants grow in a relatively static environment. The lack of such external stimulation may cause the plants to be too weak. Horizontal shaking can simulate the stimulation of this natural environment, which helps to increase the physiological activity and resistance of plants. The round block 16 is slidably connected to the U-shaped frame 17. The U-shaped frame 17 limits the round block 16, and the telescopic end of the electric push rod 7 is in contact with the limiting groove. 18 are engaged, which can simulate weak vibrations in the natural environment, such as slight vibrations of wind or soil. This stimulation helps to enhance the resistance of plants and promote the healthier growth of plants. A top plate 14 is fixedly connected between the other ends of several fixing rods 13. A slide groove 15 is opened in the middle of the top plate 14. An electric push rod 7 is installed on the top surface of the box body 1. By adjusting the distance between the baskets, the operator can perform operations such as pruning, fertilizing, changing water and checking the health status of plants more flexibly during the management process. A wider spacing can make the operation more convenient and avoid difficulties in operation caused by too dense plants, especially when carrying out pest control and checking the health status of plant roots and leaves. The loose spacing can improve the efficiency and convenience of operation, and the electric push rod 7 can be used to adjust the distance between the baskets. The telescopic end of the push rod 7 is slidably connected with the box body 1, the through end of the electric push rod 7 is located in the slide groove 15, and the through end of the electric push rod 7 is slidably connected with the top plate 14, the through end of the electric push rod 7 is fixedly connected with a round block 16, and the slide rail 11 limits the movable plate 12, and a connecting column 27 is fixedly connected to the center of the bottom surface of the movable plate 12, and a cross slide 26 is fixedly connected to the other end of the connecting column 27. A circular plate 29 is arranged in the gap between the cross slide 26 and the box body 1, and the circular plate 29 is rotatably connected to the box body 1. A sliding rod 30 is fixedly connected to the side of the circular plate 29 away from the box body 1, and the sliding rod 30 is located on the side of the eccentric part of the circular plate 29, and the sliding rod 30 is located in the through groove 28. The sliding rod 30 is slidably connected with the cross slide 26, and a motor 10 is installed on one side of the bottom surface of the box body 1.The output end of the motor 10 is rotatably connected to the housing 1, and the through end of the motor 10 is fixedly connected to the circular plate 29. Appropriate spacing can effectively reduce contact between plants and prevent moisture from being trapped between adjacent plants, thereby reducing the risk of the spread of mold, fungi and other pathogens. Especially in an environment with high temperature and humidity, if the plants are too dense, diseases are prone to spread. A through slot 28 is provided on one side of the cross slide 26. The two ends of the cross slide 26 are slidably connected to the limit frame 25. The limit frame 25 is fixedly connected to the housing 1, and the limit frame 25 limits the cross slide 26. A gap is set between the cross slide 26 and the housing 1, which helps to simulate slight vibrations or wind in the natural environment, so that the roots of the plants grow in a uniform direction. Especially in the tissue culture process of Hainan yellow rattan, the normal development of the root system is crucial to the later cultivation. Through horizontal shaking, the roots get a more uniform supply of water and nutrients, which helps to develop better and prevent the problem of excessively concentrated root growth.

[0032] The working principle of this embodiment is as follows: after Hainan yellow rattan seeds are placed in the first placement basket 19 and the second placement basket 20 in the box body 1, the handle 6 is closed, and the integrated power supply 8 provides power, so that the electric push rod 7 and the motor 10 operate at the same time. At the same time, the heating rod 9 is heated, and the electric push rod 7 drives the round block 16 to move. Because the round block 16 is engaged with the U-shaped frame 17, the U-shaped frame 17 moves simultaneously with the telescopic end of the electric push rod 7, thereby driving the second placement basket 20 at the bottom of the bottom top plate 14 to move along the linear direction of the fixed rod 13, and under the joint action of the third connecting plate 23 and the fourth connecting plate 24 and other connecting plates , so that the second placement baskets 20 on both sides of the first placement basket 19 move in different directions or opposite directions, thereby changing the distance between the first placement basket 19 and the second placement basket 20, the motor 10 drives the circular plate 29 to rotate, so that the slide bar 30 slides in the through groove 28, and at the same time drives the cross slide plate 26 to slide in the limit frame 25, and when the slide bar 30 rotates one circle, the cross slide plate 26 moves in the opposite direction, and the circular plate 29 rotates continuously, so that the cross slide plate 26 performs linear reciprocating motion in the limit frame 25, and under the action of the connecting column 27, the movable plate 12 on the slide rail 11, follows and performs linear reciprocating motion synchronously.

[0033] When the movable plate 12 performs linear reciprocating motion, the telescopic end of the electric push rod 7 moves back and forth in the slide groove 15 of the top plate 14. At the same time, the round block 16 moves simultaneously in the limit groove 18 of the U-shaped frame 17 to adapt to the moving trajectory of the movable plate 12 and prevent motion interference, thereby enhancing the air flow in the box 1, preventing air stagnation in local areas, and ensuring that the exchange of gases such as oxygen and carbon dioxide in the culture environment is more uniform.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
