Problems solved by technology

[0005] In summary, due to the slow growth of purple-red vegetables and insufficient anthocyanin content, even if the purple-red vegetables are changed to a continuous light mode to achieve coloring at the later stage of harvesting, the coloring degree is limited and the yield will decrease significantly.

Embodiment 1

[0028] The present embodiment 1 has adopted Zimei lettuce as a sample, and the specific cultivation steps are as follows:

[0029] (1) Sowing seedlings

[0030] Select Zimei lettuce seeds, soak the Zimei lettuce seeds in clear water, sow them into sponge squares, one for each hole; then place the sponge blocks sown with Zimei lettuce seeds in a germination box for germination, and wait until the seeds are white Afterwards, adopt hydroponics to carry out seedling raising treatment, water the nutrient solution once every 2 days in the seedling raising stage, control the EC value of the nutrient solution to be 0.8ms / cm, and the pH is 6.0-7.0;

[0031] (2) Cultivation and colonization

[0032] When Zimei lettuce grows to 4-5 true leaves, select uniform Zimei lettuce seedlings and transplant them to the planting board. The spacing between planting rows is 15cm×20cm, and put the planted Zimei lettuce into the nutrient solution tank For cultivation, the nutrient solution film culti...

Embodiment 2

[0049] The present embodiment 2 has adopted red rosa lettuce as a sample, and the specific cultivation steps are as follows:

[0050] (1) Sowing seedlings

[0051] Select the red rosa lettuce seeds, after the red rosa lettuce seeds are soaked in clear water, sow them in the sponge square, one for each hole; After the seeds are white, use hydroponics to raise seedlings, water the nutrient solution every 2 days during the seedling raising stage, control the EC value of the nutrient solution to 1.0ms / cm, and the pH to 6.0-7.0;

[0052] (2) Cultivation and colonization

[0053] When the red rosa lettuce seedlings grow to 4-5 true leaves, select the uniform red rosa lettuce seedlings and transplant them on the planting board. The distance between planting rows is 15cm×20cm. Cultivate in a nutrient solution tank, the EC value of the nutrient solution is 1.8ms / cm, the pH is 6.0-7.0, the temperature of the nutrient solution is 20-22°C, and the dissolved oxygen is 5-6mg / L. The envir...

Embodiment 3

[0070] The present embodiment 3 has adopted red wrinkled lettuce as a sample, and the specific cultivation steps are as follows:

[0071] (1) Sowing seedlings

[0072] Select the red wrinkled lettuce seeds, soak the red wrinkled lettuce seeds in clear water, and sow them into sponge squares, one for each hole; then place the sponge blocks sown with red wrinkled lettuce seeds in a germination box for germination, and wait until the seeds are white Afterwards, adopt hydroponics to carry out seedling raising treatment, water the nutrient solution once every 2 days in the seedling raising stage, control the EC value of nutrient solution to 1.2ms / cm, and pH is 6.0-7.0;

[0073] (2) Cultivation and colonization

[0074] When the red wrinkled lettuce grows to 4-5 true leaves, select uniform red wrinkled lettuce seedlings and transplant them to the planting board. The distance between planting rows is 15cm×20cm, and put the red wrinkled lettuce after planting into the nutrient soluti...

Abstract

The invention relates to the technical field of plant lighting, in particular to a light environment control method for controlling plant metabolic substances. In all stages of plant cultivation, traditional full artificial continuous lighting is adopted, and at least one type of intermittent lighting is added, by cooperating with other growing environments, aubergine vegetables good in coloring can be rapidly obtained, reduction of output cannot occur, and meanwhile the anthocyanin content, vitamin C and soluble protein content in the aubergine vegetables can be improved; the quality of the aubergine vegetables is further improved, and the appearance and flavor of the aubergine vegetables are improved.

Description

technical field [0001] The invention relates to the technical field of plant lighting, in particular to a light environment control method for regulating plant metabolites. Background technique [0002] Metabolism activities in plants are divided into primary metabolism and secondary metabolism, which occur in all plants and involve the metabolism of essential substances such as chlorophyll, sugar, amino acid, fatty acid, nucleic acid, etc. The metabolism of non-essential substances for life is secondary metabolism. Secondary metabolites are the result of the interaction between plants and their living environment during the long-term evolution process, mainly including small molecular organic compounds such as alkaloids, flavonoids, terpenoids and saponins, and their production and distribution are usually related to species, organs, tissues and growth Developmental stage specificity. Metabolites produced by different plants, especially secondary metabolites, have importa...
