Description

Technical Field

[0001] The present invention belongs to the technical field of rapeseed breeding, and in particular relates to a light cultivation device for rapeseed breeding. Background Art

[0002] Rapeseed is one of the important oil crops in the world. Its seed oil content is relatively high, generally about 40%, and high-yield varieties can reach more than 50%. By breeding to improve the yield and oil content of rapeseed, the supply of edible oil can be increased, the contradiction between supply and demand of oils and fats can be alleviated, and the national edible oil security can be guaranteed.

[0003] At present, for the research in the agricultural field, there is small-scale experimental breeding of rapeseed. Small-scale experiments are convenient for fine management and observation of breeding materials. Personalized cultivation management measures can be formulated according to the characteristics of different materials, the growth and development of each material can be accurately recorded and analyzed, varieties with excellent traits can be quickly screened out, and the breeding process can be accelerated. When breeding rapeseed, a light cultivation device is needed to provide a stable and suitable growth environment for rapeseed breeding, and meet the needs of different rapeseed varieties at different growth stages. For example, a light cultivation box for rapeseed breeding proposed in the patent with the patent announcement number CN217446027U.

[0004] Rapeseed has different requirements for light intensity at different growth stages. The seedling stage is relatively fragile and requires relatively less light. It is necessary to avoid damage to the seedlings due to too strong light, and at the same time meet the basic needs of its photosynthesis to promote the normal growth of leaves and roots. As the plant grows and enters the vigorous vegetative growth stage, the light requirement increases. At present, the light intensity is adjusted by artificial observation of the changes in the rapeseed breeding process, resulting in untimely insufficient light intensity. Too strong light will cause the rapeseed leaves to be burned, the photosynthesis to be inhibited, and the growth and development to be hindered. Too weak light will cause insufficient photosynthesis of rapeseed, the plants to grow thin and weak, the leaves to turn yellow, the flowering period to be delayed, and the seed setting rate to be reduced. Moreover, in the light cultivation box for rapeseed breeding proposed in the patent with the patent announcement number CN217446027U, lateral light is used. Only using lateral light will cause the rapeseed plants to bend and grow towards the light source side, resulting in the phenomenon of uneven crown, leading to uneven plant morphology, affecting its photosynthesis area and efficiency, and the fixed-position light makes it impossible for the rapeseed seedlings to fully and evenly receive light on all parts, resulting in growth differences between the light-facing side and the backlight side of the rapeseed seedlings, affecting the cultivation quality of the seedlings. Summary of the Invention

[0018] Compared with the existing technology, the beneficial effects of the present invention are as follows:

[0019] 1. By setting up an incubator, a growth state recognition mechanism, a self-sensing regulation mechanism, and a lighting lamp, it is possible to automatically identify the growth stages during the rapeseed breeding process and automatically regulate the lighting intensity of the lighting lamp based on the growth stage process of rapeseed breeding. The lighting intensity is made smaller in the initial growth stage and increased in the later growth stage. Since rapeseed seedlings are relatively fragile in the seedling stage and require relatively less light, a lower-intensity light can prevent the seedlings from being damaged by excessive light while meeting their basic photosynthesis requirements, promoting the normal growth of leaves and roots. As the plant grows and enters the vigorous vegetative growth stage, the light demand increases, and increasing the lighting intensity can enhance photosynthesis and accumulate more photosynthetic products, laying a foundation for the lush growth of the plant and subsequent reproductive growth.

[0020] 2. By setting up a growth state recognition mechanism, a self-sensing regulation mechanism, a supporting and rotating mechanism, a clamping and placing mechanism, and a culture tank, during the rapeseed breeding process, the position of the rapeseed can be continuously adjusted so that all parts of the seedlings can receive light more fully and evenly, avoiding the growth differences between the light-facing side and the backlight side caused by a fixed light direction, which helps to cultivate rapeseed seedlings with symmetrical morphology, strong growth, and uniformity, improving the overall quality of the seedlings. Moreover, the moving speed of the position is automatically regulated based on the growth stage of the rapeseed. A lower moving speed is used in the initial seedling stage to avoid damaging the seedlings due to too fast a moving speed. As the seedlings grow, the moving speed is actively increased to meet their light requirements and promote the rapid growth of the plant.

[0021] 3. By setting up a self-sensing regulation mechanism and a photoperiod follow-up control mechanism, the photoperiod can be automatically regulated based on the growth stage of the rapeseed. The lighting time is shorter in the initial growth stage, and as the rapeseed grows, the lighting time is automatically extended to ensure the developmental stability of rapeseed growth and avoid abnormal rapeseed growth and development caused by inaccurate photoperiod control, such as early or delayed flowering, which affects the breeding process and seed yield.

[0037] The operating principle of the present invention is described as follows: Rapeseed is placed in the culture tank 8 for planting and cultivation. The lighting lamp 7 provides light to promote the breeding process of rapeseed. During the cultivation process, the rotating motor 26 drives the input end of the first reduction gearbox 25 to rotate, and then drives the rotating shaft 27 through the output end of the first reduction gearbox 25 to drive the rotating circular plate 21 to rotate, thereby driving a plurality of culture tanks 8 to revolve. During the revolution process, due to the meshing transmission of the transmission gears 23 relative to the annular internal gear ring 24, the plurality of transmission gears 23 drive the self-rotating shafts 22 and the culture tanks 8 to rotate, further adjusting the position of the rapeseed, enabling all parts of the rapeseed seedlings to receive light more fully and evenly, avoiding the growth differences between the light-facing surface and the backlight-facing surface caused by a fixed light direction, contributing to cultivating rapeseed seedlings with symmetrical shapes, strong growth, and uniformity, and improving the overall quality of the seedlings;

[0038] Every 12 hours, the electric push rod 32 pushes the camera 33 downward, and the camera 33 takes pictures and feeds back the state of rapeseed breeding, regularly taking pictures or videos of the rapeseed plants, recording their growth forms, color changes and other characteristics, and feeding them back to the monitoring cloud. By analyzing these images and videos, the growth status of rapeseed can be intuitively understood, such as the size, color, growth rate of the leaves, and the overall growth trend of the plants, so as to judge the growth stage it is in;

[0039] And based on the obtained rapeseed growth stage information, the power supply device is controlled to supply power to the boosting electromagnetic plate 46. When the boosting electromagnetic plate 46 is energized, it generates the same magnetism as the force-bearing permanent magnet plate 45, thereby giving a magnetic thrust to the lifting plate 43, causing the lifting plate 43 to slide along the guiding slide rod 42 against the elastic force of the reset spring 44. Specifically, when the rapeseed breeding is detected to be in a later stage by the camera, the power supply device is controlled to supply a larger current to the boosting electromagnetic plate 46, so that the lifting plate 43 moves upward by a greater distance. And after the position of the lifting plate 43 is adjusted by each current supply, the micro electric push rod 412 is controlled to act. The micro electric push rod 412 pushes the anti-slip supporting plate 413 to move, so that the anti-slip supporting plate 413 abuts against the inner wall of the regulation shell 41 to fix the position of the lifting plate 43, eliminating the need to continuously supply power to the boosting electromagnetic plate 46, which is convenient for use. When the lifting plate 43 adjusts and moves, it drives the transmission rack 47 to move synchronously. Then, through the meshing action of the transmission rack 47 and the synchronous gear 410, the input end of the second reduction gearbox 48 is driven to rotate self. Then, the output end of the second reduction gearbox 48 drives the output shaft 411 to rotate at a reduced speed, and further drives the rotating end of the potentiometer 49 to rotate. The potentiometer 49 is connected in series in the power supply circuit of the lighting lamp 7. In essence, the potentiometer 49 is a variable resistor, which forms a voltage dividing circuit with other components (such as power supply, load, etc.) in the circuit. According to the voltage division formula of series resistors, in a series circuit, the voltage across each resistor is proportional to its resistance value. The potentiometer 49 changes the voltage across its two ends by changing its own resistance value connected to the circuit, thereby realizing the adjustment of the output voltage, and accordingly adjusting the light intensity. Specifically, when the rapeseed breeding is in a later growth stage, which causes the lifting plate 43 to move upward by a greater distance, the rotating angle of the rotating end of the potentiometer 49 becomes larger, which makes the resistance value of the potentiometer 49 connected to the circuit smaller, and further makes the supply current of the lighting lamp 7 larger. And since the lighting lamp 7 is a DC lamp, the luminous intensity of the lighting lamp 7 becomes larger. It can automatically adjust the light intensity based on the rapeseed breeding process. The light intensity is smaller in the initial stage of breeding and larger in the later stage of breeding. Different growth stages of rapeseed have different requirements for light intensity. The seedling stage is relatively fragile and requires relatively less light, generally 3000 - 5000 lux is appropriate. This intensity can prevent the seedlings from being damaged due to excessive light and can also meet the basic requirements of their photosynthesis, promoting the normal growth of leaves and roots. As the plant grows, it enters the vigorous vegetative growth stage, and the light requirement increases. The light intensity can be increased to 5000 - 8000 lux to enhance photosynthesis and accumulate more photosynthetic products, laying a foundation for the lush growth of the plant and subsequent reproductive growth. In the reproductive growth stage, such as the flowering stage and pod-setting stage, to ensure the development of flower organs, pollination and fertilization, and seed filling, the light intensity needs to be further increased to 8000 - 12000 lux;

[0040] Moreover, the potentiometer 49 is also connected in series to the power supply circuit of the rotary motor 26, and the rotary motor 26 is a DC motor. When the rapeseed breeding reaches the later stage, the smaller the resistance value of the potentiometer 49 connected in, the higher the rotational speed of the rotary motor 26, thus accelerating the movement of the rapeseed position. Since rapeseed seedlings have different light requirements and adaptability at different growth stages, in the initial stage of the seedlings, as the seedlings are relatively fragile and grow slowly, the rotation speed should be slower, set at 1 - 2 rotations per hour. This can avoid damaging the seedlings caused by too fast rotation and ensure that they receive sufficient light for photosynthesis. As the seedlings grow gradually and enter the vigorous growth stage, the rotation speed can be appropriately increased to 3 - 5 rotations per hour to meet their light requirements and promote the rapid growth of the plants;

[0041] When conducting light cultivation on rapeseed and starting the light lamp 7, the reduction motor 57 is synchronously controlled to act. The output end of the reduction motor 57 drives the arc-shaped pressing block 58 to move within the control circular shell 51, and the time for the reduction motor 57 to drive the arc-shaped pressing block 58 to rotate one circle within the control circular shell 51 is 24 hours. When the arc-shaped pressing block 58 moves and presses on the light termination switch 55, the feedback control terminal controls the light lamp 7 to turn off, causing the rapeseed breeding to enter the dark stage. When the arc-shaped pressing block 58 moves again and presses on the light start switch 52, the light lamp 7 starts working again, entering the bright stage, which can automatically control the light cycle. Specifically, when the rapeseed breeding reaches a more later stage, the larger the angle by which the output shaft 411 on the second reduction gearbox 48 drives the linkage shaft 53 to rotate through the reduction sprocket assembly 56, the greater the distance the light termination switch 55 moves, and the longer the time required for the arc-shaped pressing block 58 to press on the light termination switch 55, thus increasing the light time. Since rapeseed is a long-day crop and is relatively sensitive to the light cycle, inaccurate light cycle control will lead to abnormal growth and development of rapeseed, such as early or delayed flowering, affecting the breeding process and seed yield. Using a cultivation device with an accurate light cycle control function and setting accurate light and dark times, during the vegetative growth stage of rapeseed, the light cycle is set to 12 - 14 hours of light and 10 - 12 hours of darkness; during the reproductive growth stage, the light cycle can be appropriately extended to 14 - 16 hours of light and 8 - 10 hours of darkness to ensure the stable progress of rapeseed breeding.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
