Embodiment example 1

[0016] After soaking the powdered geranium seeds, sow them into sponge squares, 1 seed per hole, and then put them in a germination box at 23°C for germination. After the seeds are white, move them into the full spectrum for cultivation. When the seedlings grow 5-10cm roots and 2 Seedling raising treatment is carried out after a true leaf is formed, and the EC value of the nutrient solution during the treatment is 0.8-1.2ms / cm. Move to the hydroponic nutrient solution for seedling management. The EC value of the nutrient solution is 1.2ms / cm, and the pH is 6.0-7.0 until 5-6 true leaves are cultivated. Select neat and consistent seedlings for transplanting and planting on the planting board, and put them in the nutrient solution tank for cultivation. The EC of the nutrient solution is controlled between 1.7-2.0ms / cm, and the pH is 6.2-6.8. At the same time, the ambient temperature during the entire planting period Conditions are 21°C during the day, 18°C ​​at night, air humidit...

Embodiment example 2

[0021] After soaking the seeds of the red horned pansy, sow them into sponge squares, 1 grain per hole, and then put them in a germination box at 23°C for germination. After the seeds are white, move them into the full spectrum for cultivation. When the seedlings grow 5-10cm roots and After 2 true leaves, the seedlings were raised, and the EC value of the nutrient solution was 0.8-1.2ms / cm during the treatment. Move to the hydroponic nutrient solution for seedling management. The EC value of the nutrient solution is 1.2ms / cm, and the pH is 6.0-7.0 until 5-6 true leaves are cultivated. Select neat and consistent seedlings for transplanting and planting on the planting board, and put them in the nutrient solution tank for cultivation. The EC of the nutrient solution is controlled between 1.7-2.0ms / cm, and the pH is 6.2-6.8. At the same time, the ambient temperature during the entire planting period Conditions are 21°C during the day, 18°C ​​at night, air humidity of 60-70%, CO ...

Embodiment example 3

[0026] After soaking the raspberry-colored carnation seeds, sow them into sponge squares, 1 seed per hole, and then put them in a germination box at 23°C for germination. After the seeds are white, move them into the full spectrum for cultivation, and wait for the seedlings to grow 5-10cm roots And after 3-4 true leaves, carry out seedling raising treatment, during the treatment, the EC value of the nutrient solution is 1.0ms / cm, and the pH is 6.5. Move to the hydroponic nutrient solution for seedling management. The EC value of the nutrient solution is 1.2ms / cm, and the pH is 6.0-6.5 until 5-6 true leaves are cultivated. Select uniform seedlings for transplanting and planting on the planting board, and put them in the nutrient solution tank for cultivation. The EC of the nutrient solution is controlled between 1.5-1.8ms / cm, and the pH is 6.5-7.0. At the same time, the ambient temperature during the entire planting period Conditions are 21°C during the day, 18°C ​​at night, ai...

Abstract

The invention discloses a method for promoting anthocyanin content accumulation of flowers in a plant factory. The wavelength range of an adopted fully-artificial light source is 380-780 nm, wherein the number of light quanta with the wavelength of 380-499 nm is 5%-12% of the total number of the light quanta of the light source, the number of the light quanta with the wavelength of 500-599 nm is 12%-18% of the total number of the light quanta of the light source, and the number of the light quanta with the wavelength of 600-780 nm is 65%-77% of the total number of the light quanta of the light source. The method is obtained by carrying out a large number of creative tests on the basis that a tester finds that LED red light with different wavelengths plays a key role in flower color regulation and control of herbaceous flowers when the flowers are planted in the plant factory, and according to the technical scheme, the content of anthocyanin can be regulated and controlled to influence the color of the flowers so as to realize the commercial value of the flowers, or the anthocyanin is extracted for food coloring, dye, medicine, cosmetics and other industries.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for promoting the accumulation of anthocyanin content in flowers in plant factories. Background technique [0002] The most important pigment that creates the color of flowers is called "anthocyanin". It is distributed in the vacuoles of cells and controls the color changes of flowers such as pink, red, purple and blue. In daily life, according to different flower varieties, flower quality grading is different. The quality of some flowers is graded objectively by the size of the flower diameter, the length of the pedicel, and the weight of a single branch, while others are graded by subjective judgments such as the shape, color, smell, cleanliness, and luster of the flower. At present, the quality of flowers is mainly improved through four environmental factors: water, fertilizer, temperature and light. Among them, the influence of light on plant ...
