Description

Technical Field

[0001] This invention relates to the technical field of plant seed production, specifically to a method for increasing the yield of leafy greens and radish seeds using laser supplemental lighting. Background Technology

[0002] Lasers can promote plant photosynthesis and increase the plant's weight index; low-dose He-Ne laser irradiation can effectively alleviate the stress damage caused by UV-B radiation to the chloroplasts of plant seedlings, thereby promoting plant photosynthesis.

[0003] In greenhouses, the seed yield of cruciferous plants is significantly affected by low light levels, necessitating supplemental lighting. However, using LED lights for supplemental lighting would be too costly and energy-intensive, hindering large-scale production. Laser lights, on the other hand, are low-cost and energy-efficient, making them a potentially viable solution to this problem. Therefore, developing a laser supplemental lighting method suitable for leafy greens and radishes to promote reproductive growth and increase seed yield is a pressing technical challenge in production. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a method that is low in cost and low in energy consumption, and can promote the reproductive growth of leafy greens and radishes to increase seed yield.

[0005] The technical solution of this invention is to provide a method for increasing the yield of leafy greens and radish seeds using laser supplemental lighting, comprising the following steps:

[0006] (1) Select two plants, bok choy and radish, and plant them on the cultivation trough platform;

[0007] (2) Position the cultivation trough platform below the laser supplement light module, and allow the two plants of cabbage and radish on the cultivation trough platform to receive the irradiation treatment of the laser supplement light module.

[0008] (3) The laser supplement light module emits red and blue light, and the red and blue light are combined in a certain ratio to form a laser irradiation field, which irradiates the plants with red and blue light within a certain period of time.

[0009] As a preferred option, in step (2), the cabbage plants begin to receive laser supplemental lighting module irradiation treatment at the 10-11 leaf stage, and the radish plants begin to receive laser supplemental lighting module irradiation treatment at the 8-9 leaf stage.

[0010] Preferably, the red light irradiation in step (3) is performed by irradiating the plant with a laser beam generated by a single red light laser generator through a homogenizing lens to form a surface light source.

[0011] Preferably, in step (3), the blue light irradiation is performed by a laser beam generated by a single blue light laser generator, which is then passed through a homogenizing lens to form a surface light source to irradiate the plant.

[0012] As a preferred option, the ratio of red light to blue light in step (3) is 9:3.

[0013] Preferably, in step (3), the laser wavelength of the red light is 650-665nm and the laser wavelength of the blue light is 440-460nm.

[0014] As a preferred option, in step (3), the laser supplemental lighting module irradiates the plant with red light and blue light in two time periods, morning and afternoon. The morning irradiation time is from 4:00 to 11:00, and the afternoon irradiation time is from 13:00 to 19:00.

[0015] Preferably, the laser supplementary lighting module irradiates the plant for 160 days in step (3).

[0016] Compared with existing technologies, the method of using laser supplemental lighting to increase the yield of leafy greens and radish seeds in this invention has the following advantages and beneficial effects:

[0017] This invention uses a laser generator on a laser supplement light module to emit red and blue laser beams in a 9:3 ratio, and forms a surface light source through a uniform light lens to irradiate the plants, promoting plant reproductive growth and increasing seed yield. Furthermore, the laser generator used in this invention to form the irradiation light source is not only low in cost but also consumes little energy, making it suitable for large-scale production applications.

[0024] The embodiments of the present invention are described in detail below: These embodiments are implemented under the premise of the technical solution of the present invention, and provide detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to the following embodiments.

[0025] Example:

[0026] This invention selected the "Yuandu No. 1" radish variety as the experimental subject, and the experimental site was located in the Jiangsu and Zhejiang region. On October 10, radish seeds were sown in the experimental area; on November 18, when the radish plants had 8-9 leaves, they were divided into two groups, with 20 radishes per replicate, and each group was replicated three times.

[0027] Experimental and control areas were set up, and two groups of radishes were transplanted into the experimental and control areas respectively. The area of ​​the experimental and control areas was 12m×32m, and each area was equipped with a substrate trough with a ridge length of 22m and a width of 50cm. The planting distance of the radishes was 30cm.

[0028] The experimental area for radishes was equipped with laser supplemental lighting modules, covering an area of ​​384 square meters. The distance between the light source and the plant was 5.5 meters. Vertical supplemental lighting was adopted at the top beam, requiring 8 laser supplemental lights to be evenly distributed. The laser supplemental lights (laser generators) emitted red and blue laser beams in a 9:3 ratio, forming a surface light source to irradiate the plants through a uniform light lens. The wavelength of the red laser light was 650-665nm, and the wavelength of the blue laser light was 440-460nm. The specific equipment parameters of the laser supplemental lights are shown in Table 1.

[0029] model CXL1-X0220-0601 Input voltage 220VAC Single lamp power 13W dimming method Infrared remote control dimming Waterproof rating IP65 Light source type LD spectrum Red to blue light ratio = 9R:3B

[0030] The laser supplemental lighting module irradiates the plants twice a day, once in the morning and once in the afternoon. The morning irradiation time is from 4:00 to 11:00, and the afternoon irradiation time is from 13:00 to 19:00, with a total irradiation time of approximately 160 days.

[0031] The control area for radishes was illuminated by natural light, without the need for supplemental lighting.

[0032] Ten normal radish plants were randomly selected from the experimental and control areas. The characteristics of each plant were investigated according to the vegetable supplemental lighting experiment survey record form. The date when 50% of the plants showed significant elongation of the shortened stem was recorded as the bolting stage; the date when 30% of the plants flowered was recorded as the initial flowering stage; and the seed harvest date was recorded when two-thirds of the pods turned yellow and the seeds at the upper part of the branches had basically changed color. The sowing date, supplemental lighting start date, bolting stage, initial flowering stage, number of effective pods per plant, number of seeds per pod, seed harvest date, average seed yield per plant (g), and germination rate of the radishes in the experimental and control areas were recorded, as shown in Table 2 below.

[0033]

[0034] Based on the above experimental results, it can be seen that the number of effective pods per plant, the number of seeds per pod, the seed yield per plant, and the thousand-seed weight of radishes treated with laser supplemental lighting are significantly increased compared with radishes under natural light.

[0035] The "Qiaodong" variety of bok choy was selected as the experimental subject, and the experimental location was the same as that for radishes. On October 10, bok choy seeds were sown in the experimental area; on November 18, when the bok choy plants had 10-11 leaves, they were divided into two groups, with 20 bok choy plants per replicate, and each group was replicated three times.

[0036] Experimental and control areas were set up, and two groups of Chinese cabbage were transplanted into the experimental and control areas respectively. The area of ​​each experimental and control area was 12m×32m, and each area was equipped with a substrate trough with a ridge length of 22m and a width of 50cm. The planting spacing of the Chinese cabbage was 30cm.

[0037] The experimental area for leafy greens was equipped with laser supplemental lighting modules, the same as the experimental area for radishes; the control area for leafy greens used natural light and did not require supplemental lighting.

[0038] Ten normal single plants were randomly selected from the experimental and control areas of Chinese cabbage. Based on the vegetable supplemental lighting experiment survey record sheet, the characteristics of each labeled plant were investigated. The date when 50% of the plants showed significant elongation of their shortened stems was recorded as the bolting stage; the date when 30% of the plants flowered was recorded as the initial flowering stage; and the date when two-thirds of the pods turned yellow and the seeds at the upper part of the branches had basically changed color was recorded as the seed harvest date.

[0039] Record the sowing date, supplemental lighting start date, bolting period, initial flowering period, number of effective pods per plant, number of seeds per pod, seed harvest date, average seed yield per plant (g), and germination rate of Chinese cabbage in the experimental and control areas, as shown in Table 3 below:

[0040]

[0041] Based on the above experimental results, it can be seen that compared with vegetables exposed to natural light, vegetables treated with laser supplemental lighting have significantly increased the number of effective pods per plant, the number of grains per pod, and the seed yield per plant, while the seed germination rate and thousand-grain weight remain unchanged.

[0042] In conclusion, laser lights are a high-quality light source suitable for the reproductive growth of leafy greens and radishes, and their application in production can effectively increase seed yield.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
