[0026] This invention provides a method for controlling the rapid color change of chili peppers, utilizing a red-blue-violet light ratio of 4:1:0.5 and a quantum density of 15-25 μmol / m². 2 The 30W supplemental lighting was used to cultivate four chili pepper varieties: Rijkswagen "Bolong 37-94" from the Netherlands, "Longjiao F4" from Jiangxi Ganhong Seed Industry, "Silui 1688" from the Netherlands, and "Sainte-Nice SV2579" from the United States.

[0027] The specific cultivation method for regulating the rapid color change of chili peppers in this invention includes: using 30W plant grow lights (red-blue-violet light ratio of 4:1:0.5) in a greenhouse. The lighting is configured as follows: one plant grow light is placed every 2 meters in each row (16 grow lights / row), ensuring 4-6 hours of supplemental lighting daily. The light source is 0.8 meters away from the growing point. An isolation row is set between two rows, with each row being 40 meters long, 1.6 meters wide, and a furrow width of 0.3 meters. The plant spacing is 45 cm, with double-row "Z"-shaped planting. 80 chili peppers are planted in each row. Each area is isolated, and the soil, topography, and other conditions within each area are kept relatively consistent. The temperature inside the greenhouse is 0-20℃, and the humidity is 40-60%.

[0028] The color-changing time of chili peppers was measured. The time from green to red was defined as the initial color-changing time, and the time from green to fully red was defined as the complete color-changing time. The results of the examples show that, in summary, for all four chili pepper varieties, treatment with the supplementary lighting provided by this invention can advance the color-changing time by more than 3 days and the complete color-changing time by more than 5 days. Especially for the long chili pepper variety, the color-changing time can be advanced by 7-8 days, and the complete color-changing time by 15 days.

[0029] To further illustrate the present invention, the technical solutions provided by the present invention will be described in detail below with reference to the accompanying drawings and embodiments, but these should not be construed as limiting the scope of protection of the present invention.

[0030] Unless otherwise specified, the production processes, experimental methods, or testing methods involved in the embodiments of this invention are all conventional methods in the prior art, and their names and / or abbreviations are all conventional names in the field, which are very clear and distinct in the relevant application areas. Those skilled in the art can understand the conventional process steps based on the names and apply the corresponding equipment, and implement them according to conventional conditions or the conditions recommended by the manufacturer.

[0031] The various instruments, equipment, raw materials or reagents used in the embodiments of this invention are not subject to any special restrictions on their source. They are all conventional products that can be purchased through regular commercial channels and can be prepared according to conventional methods known to those skilled in the art.

[0032] Example 1

[0033] The following chili pepper varieties were selected for research: the Dutch Rijkswyn 'Bolong 37-94' (L1), a variety tolerant to low temperatures and low light; the common chili pepper variety 'Longjiao F4' (L2), a variety tolerant to low temperatures and low light; the Dutch Rijkswyn 'Silui 1688' (L3); and the common long chili pepper variety 'Saint-Nice SV2579' (L4), a variety from Bayer, USA. All chili pepper varieties were commercially available.

[0034] Seedlings were started on September 1, 2024, transplanted on October 15, and harvested in late May of the following year.

[0035] LED lighting will be used for supplemental illumination from November 30, 2024 to March 1, 2025. The temperature inside the greenhouse will be 0-20℃, and the humidity will be 40-60%.

[0036] A blank control group (CK) was set up, meaning no plant grow light treatment was used; the three experimental groups were T1: using a 30W plant grow light (red-blue-violet light ratio: 4:1:0.5, photon density: 15-25 μmol / m³). 2 T2: Use a 15W full-spectrum plant grow light; T3: Use a 15W plant grow light (red, blue and violet light ratio: 8:1:0.25).

[0037] Lighting treatment: Plant grow lights (30W spaced 2m apart, 16W / row; 15W spaced 1.5m apart, 26W / row) are placed in each 40m row. The placement of lights in each row is as follows: Figure 1 As shown. Ensure 4-6 hours of supplemental lighting daily. The distance between a 30W light source and the growth point should be 0.8 meters, and the distance between a 15W light source and the growth point should be 0.6 meters.

[0038] Each experimental group and control group were treated in one bed, with each treatment replicated three times. An isolation bed was set up between each treatment. The beds were 40m long, 1.6m wide, with 0.3m wide furrows and a plant spacing of 45cm. Planting was done in a double-row "Z" pattern, with 80 pepper plants per bed. Each area was isolated and included three replicates. Soil and topography conditions were kept relatively consistent within each area. The pepper planting area was as follows: Figure 2 As shown.

[0039] The color-changing time of chili peppers is measured. The time it takes for the pepper to change from green to red is the initial color-changing time, and the time it takes for the pepper to turn completely red is the complete color-changing time. Figure 3 The state shown indicates that the chili pepper is in the initial color change stage.

[0040] The results are shown in Table 1-4:

[0041] Table 1. Lighting treatment results of Rijkswagen "Bolon 37-94" in the Netherlands

[0042]

[0043] Table 1 shows that for the low-temperature and low-light tolerant screw pepper variety, Rijkswagen "Bolong 37-94" (L1) from the Netherlands, using T1 and T2 supplemental lighting can advance the color change by 2-3 days, and complete color change by 3-5 days, while T3 can delay the color change by 1 day.

[0044] Table 2. Light treatment results of "Longjiao F4" cultivar from Jiangxi Ganhong Seed Industry.

[0045]

[0046] Table 2 shows that for the common screw pepper variety, Jiangxi Ganhong Seed Industry's "Longjiao F4" (L2), using T1 supplemental lighting can advance the color change by 4 days and advance the complete color change by 6 days. T2 and T3 can delay the color change by 4-5 days and delay the complete color change by 6-9 days.

[0047] Table 3. Illumination treatment results of Rijkswagen "Silui 1688" in the Netherlands

[0048]

[0049] Table 3 shows that for the low-temperature and low-light tolerant pepper variety, Rijkswagen "Silui 1688" (L3) from the Netherlands, using T1 supplemental lighting can advance the color change by 7 days and the complete color change by 15 days. The effects of T2 and T3 treatments are not obvious.

[0050] Table 4. Illumination results of Bayer's "Seneca SV2579" in the United States.

[0051]

[0052] Table 4 shows that for common chili pepper varieties, such as Bayer “Saint-Nice SV2579” (L4) from the United States, using T1 supplemental lighting can advance the color change by 8 days and the complete color change by 15 days. T2 and T3 can advance the color change by 1 day and the complete color change by 0-1 days.

[0053] The color-changing conditions of chili varieties L3 and L4 under different light quality treatments were recorded, and the results are as follows: Figure 4-7 As shown, at the same time, the peppers treated with supplemental lighting showed a significant color change. Especially under T1 light quality treatment, some peppers had already achieved complete color change.

[0054] In summary, for all four chili pepper varieties, T1 lamp treatment can advance the color change by more than 3 days and the complete color change by more than 5 days. In particular, for the long chili pepper variety, the color change can be advanced by 7-8 days and the complete color change can be advanced by 15 days.

[0055] Example 2

[0056] Using no supplemental lighting as a control, samples were taken from the initial color-changing state of peppers of varieties L3 and L4 treated under T1 light quality conditions (two parallel measurements were performed for each variety) for pigment content analysis.

[0057] The main pigment components of chili peppers are carotenoids and anthocyanins. The pigment content of chili peppers was determined, and the results are shown in Table 5.

[0058] Table 5. Results of Pigment Content Detection

[0059]

[0060] The results showed that, compared with the control without supplemental light, the contents of neoxanthin, capsanthin, zeaxanthin, β-cryptoxanthin, α-carotene, and anthocyanins in the L3 and L4 pepper varieties were increased under the T1 treatment, indicating that supplemental light treatment can promote the accumulation of red and yellow pigments and cause the peppers to change color earlier.

[0061] Although the above embodiments have provided a detailed description of the present invention, they are only some embodiments of the present invention, and not all embodiments. People can obtain other embodiments based on these embodiments without creative effort, and these embodiments all fall within the protection scope of the present invention.
