[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The light regulating device for tissue culture of Dendrobium officinale is provided with a light source irradiation structure. When the light regulating device for tissue culture of Dendrobium officinale is used, the culture device is assembled to the upper end of the base. When the culture device is used to plant Dendrobium officinale seedlings, the servo motor is started through the coordination of the adjustable composite light source box, the rotating rod, the double-sided light source board and the red and blue composite light LED light strip, so as to drive the rotating rod to rotate, thereby driving the double-sided light source board to rotate synchronously. At this time, the double-sided light source board is flipped inside the flip cavity, and the plane where the double-sided light source board is located is flipped synchronously to make it enter the flip cavity, and the red and blue composite light LED light strip on one side placed inside the flip cavity is flipped to face downward. At this time, the red and blue composite light LED light strip is turned downward. The light source emitted by the D light bar faces the Dendrobium officinale seedlings. The red and blue composite light emitted by the red and blue composite light LED light bar is beneficial to the increase of the number of leaves of the transplanted seedlings, and promotes the rooting and root elongation of the transplanted seedlings. In terms of biomass accumulation, the fresh weight and dry weight of the transplanted Dendrobium officinale seedlings under the red and blue composite light treatment reach the maximum value, which can make the cultivation effect of Dendrobium officinale better in the rooting growth stage of the seedlings. After the Dendrobium officinale has gone through the rooting and root growth process of the seedlings, the servo motor can be reversed to flip the red LED light bar placed inside the flip cavity out of the flip cavity. At this time, the irradiation of the red and blue composite light LED light bar is stopped, and the irradiation of the red LED light bar is started to emit red light The red light is beneficial to the elongation of the stem and leaves of Dendrobium officinale, making the stem and leaf stages of Dendrobium officinale grow better. When the servo motor starts to drive the rotating rod to rotate, it uses the connecting belt to synchronously drive the rotating rod to rotate, and then drives the connecting seat to rotate synchronously, and then drives the light-transmitting box to rotate and adjust synchronously, and then drives the polymer lens to synchronously follow the light-transmitting box to adjust. When the red and blue composite light LED light bar is flipped to face downward, the light-transmitting box synchronously covers the bottom of the red and blue composite light LED light bar. At this time, the red and blue composite light emitted by the red and blue composite light LED light bar can be gathered by the polymer lens, so that it can be independently irradiated on the Dendrobium officinale seedlings. The polymer lenses are evenly arranged on the upper surface of the light-transmitting box. And the polymer lens is arranged corresponding to the red and blue composite light LED light strip arranged on the side wall of the double-sided light source plate, so that the red and blue composite light emitted by the red and blue composite light LED light strip arranged on the double-sided light source plate can be completely gathered by the polymer lens, so that it can be completely irradiated on the Dendrobium officinale seedlings, so that the illumination effect of the red and blue composite light is better, which is more conducive to increasing the number of leaves of the transplanted seedlings and promoting the rooting and root elongation of the transplanted seedlings. Through this design, the Dendrobium officinale tissue culture light adjustment device can use different color light sources to irradiate and cultivate it at different culture stages, so that the Dendrobium officinale can develop better during the culture process, which is beneficial to the growth of Dendrobium officinale and improves the practicability and culture effect of the device.

[0016] 2. Using the light regulating device for tissue culture of Dendrobium officinale, the culture box is placed inside the installation groove, so that the culture box and the Dendrobium officinale seedlings cultured thereon can be protected and stably protected, and the side baffles fixedly connected to the upper end of the installation groove are used to protect the sides of the Dendrobium officinale to prevent the seedlings from being damaged by external factors. When installing the culture box, it can be placed inside the installation groove, and the mounting seat is synchronously inserted into the groove opened inside the base, and then the mounting bolts are rotated to make them enter the mounting seat and the base at the same time, so that the culture box can be conveniently installed inside the installation groove. Through this design, the light regulating device for tissue culture of Dendrobium officinale can conveniently install the Dendrobium officinale culture tissue on the upper end of the base and protect it, thereby improving the practicability and protectiveness of the device.

[0017] 3. When using the light adjustment device for tissue culture of Dendrobium officinale, the height of the light source can be adjusted so that it is placed at a suitable height to emit light for absorption by Dendrobium officinale. When adjusting the height of the light source, the cylinder can be started to make its output end telescopically adjusted, thereby driving the adjustable composite light source box to synchronously perform lifting and lowering adjustments. At this time, the red LED light bar and the red and blue composite light LED light bar light sources installed inside the adjustable composite light source box can be synchronously lifted and lowered, so that the light source can be placed at an appropriate height for irradiation and cultivation. When the cylinder is started to drive the adjustable composite light source box to perform lifting and lowering adjustments, the adjusting column is synchronously telescopically adjusted and moved inside the culture box so that it stably supports the adjustable composite light source box, so that it can maintain balance during lifting and lowering adjustments, and its adjustment process is more stable. Through this design, the illumination angle of the light source can be adjusted by the light adjustment device for tissue culture of Dendrobium officinale, so that it is convenient to irradiate the growth of Dendrobium officinale emitting light at different heights, thereby improving the practicability and adjustability of the device.

[0038] Working principle:

[0039] When using the Dendrobium officinale tissue culture light adjustment device, the culture device is assembled to the upper end of the base 111. When the Dendrobium officinale seedlings are planted on the culture device, the servo motor 114 is started through the coordination of the adjustable composite light source box 211, the rotating rod 213, the double-sided light source plate 214 and the red and blue composite light LED strip 216, so as to drive the rotating rod 213 to rotate, thereby driving the double-sided light source plate 214 to rotate synchronously. At this time, the double-sided light source plate 214 is flipped inside the flip cavity 212, and the plane where the double-sided light source plate 214 is located is flipped synchronously to make it enter the flip cavity 212, and the red and blue composite light LED strip 216 placed inside the flip cavity 212 is flipped to face the direction toward the left. In this case, the light source emitted by the red-blue composite light LED light bar 216 faces the Dendrobium officinale seedlings. The red-blue composite light emitted by the red-blue composite light LED light bar 216 is beneficial to the increase of the number of leaves of the transplanted seedlings, and promotes the rooting and root elongation of the transplanted seedlings. In terms of biomass accumulation, the fresh weight and dry weight of the transplanted Dendrobium officinale seedlings under the red-blue composite light treatment reach the maximum value, which can make the cultivation effect of Dendrobium officinale better in the rooting growth stage of the seedlings. After the Dendrobium officinale has gone through the rooting and root growth process of the seedlings, the servo motor 114 can be reversed to flip the red LED light bar 215 placed in the flip chamber 212 out of the flip chamber 212, and the red-blue composite light LED light bar 216 is stopped at this time. The irradiation of the D light bar 216 starts the irradiation of the red LED light bar 215, so that it emits a red light source. The red light is beneficial to the elongation of the stem segments and leaves of Dendrobium officinale, so that the stem and leaf stages of Dendrobium officinale grow better. When the servo motor 114 starts to drive the rotating rod 213 to rotate, it uses the connecting belt 223 to synchronously drive the rotating rod 218 to rotate, and then drives the connecting seat 219 to rotate synchronously, and then drives the light-transmitting box 220 to rotate and adjust synchronously, and then drives the polymer lens 221 to synchronously follow the light-transmitting box 220 to adjust. When the red-blue composite light LED light bar 216 is flipped to face downward, the light-transmitting box 220 synchronously covers the bottom of the red-blue composite light LED light bar 216. At this time, the red The red and blue composite light emitted by the blue composite light LED light strip 216 can be gathered by the polymerizing lens 221 so that it can be independently irradiated on the Dendrobium officinale seedlings. The polymerizing lenses 221 are evenly arranged on the upper surface of the light-transmitting box 220, and the polymerizing lenses 221 are arranged corresponding to the red and blue composite light LED light strip 216 arranged on the side wall of the double-sided light source plate 214, so that the red and blue composite light emitted by the red and blue composite light LED light strip 216 arranged on the double-sided light source plate 214 can be completely gathered by the polymerizing lens 221 so that it can be completely irradiated on the Dendrobium officinale seedlings, so that the red and blue composite light can have a better illumination effect, which is more conducive to increasing the number of leaves of the transplanted seedlings and promoting the rooting and root elongation of the transplanted seedlings.

[0040] By using the Dendrobium officinale tissue culture light adjustment device, the culture box 312 is placed inside the installation groove 311, so that the culture box 312 and the Dendrobium officinale seedlings cultured thereon can be protected and stabilized, and the side baffle 313 fixedly connected to the upper end of the installation groove 311 is used to protect the surrounding sides of the Dendrobium officinale to prevent the seedlings from being damaged by external factors. When installing the culture box 312, it can be placed inside the installation groove 311. At this time, the mounting seat 314 is synchronously inserted into the groove opened inside the base 111, and then the mounting bolt 315 is rotated to make it enter the mounting seat 314 and the base 111 at the same time, so that the culture box 312 can be easily installed into the mounting groove 311.

[0041] When using the Dendrobium officinale tissue culture light adjustment device, the height of the light source can be adjusted to place it at a suitable height to emit light for absorption by the Dendrobium officinale. When adjusting the height of the light source, the cylinder 411 can be started to make its output end telescopically adjustable, thereby driving the adjustable composite light source box 211 to be synchronously raised and lowered. At this time, the red LED light bar 215 and the red and blue composite light LED light bar 216 light sources installed inside the adjustable composite light source box 211 can be synchronously raised and lowered, so that the light source can be placed at an appropriate height for irradiation and cultivation. When the cylinder 411 is started to drive the adjustable composite light source box 211 to be raised and lowered, the adjustment column 413 is synchronously telescopically adjusted and moved inside the culture box 312, so that it can stably support the adjustable composite light source box 211, so that it can maintain balance during the lifting and lowering adjustment, and the adjustment process is more stable. The operation is now completed.
