Problems solved by technology

[0004] Purple and red lettuce are one of the salad vegetable varieties favored by consumers more and more. At present, when purple and red lettuce are cultivated in plant factories, it is often difficult for the purple and red lettuce produced to show the purple and red lettuce itself. The original variety characteristics, while the yield is greatly reduced
Therefore urgently need to take some measures to solve the problem of poor coloring and low yield of purple and red lettuce cultivated in plant factories

Embodiment example 1

[0021] Choose Zimei lettuce seeds with full seeds, soak the seeds of Zimei lettuce, sow them in 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 to the hydroponic nutrient solution The seedling management is carried out in the medium, the EC value of the nutrient solution is 0.8-1.2mS / cm, the pH is 6.0-7.0, until 4-5 true leaves are cultivated. Select neat and consistent seedlings with 4-5 true leaves for transplanting and planting on the planting board, the distance between planting rows is 15cm×20cm, and put them in the nutrient solution tank for cultivation. The nutrient solution film cultivation technology is adopted, and the nutrient solution EC control Between 1.6-1.8, the pH is 6.0-7.0, until the harvest, the whole planting period is 20 days, at the same time, the temperature of the nutrient solution is controlled at 21°C, the dissolved oxygen is 5-6mg / L, and the ambient temperature cond...

[0027] Choose red rosa lettuce seeds with full grains, soak the seeds of red rosa lettuce, sow them in 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 to hydroponics Seedling management is carried out in the nutrient solution, the EC value of the nutrient solution is 0.8-1.2mS / cm, the pH is 6.0-7.0, until 4-5 true leaves are cultivated. Select neat and consistent seedlings with 4-5 true leaves for transplanting and planting on the planting board, the distance between planting rows is 15cm×20cm, and put them in the nutrient solution tank for cultivation. The nutrient solution film cultivation technology is adopted, and the nutrient solution EC control Between 1.6-1.8, the pH is 6.0-7.0, until harvesting, the whole planting period is 22 days, and during the whole planting period, the temperature of the nutrient solution is controlled at 21°C, the dissolved oxygen is 5-6mg / L, and the ambient temp...

Abstract

The invention discloses a light environment for indoor purple and red lettuce production. The wavelength range of the light environment is 380-780 nm, wherein the number of light quanta with the wavelength in the range of 500-599 nm accounts for 0% of the total number of light quanta with the wavelength in the range of 380-780 nm. The ratio of the sum of the number of the light quanta with the wavelength in the range of 700-780 nm and the number of the light quanta with the wavelength in the range of 600-699 nm to the number of the light quanta with the wavelength in the range of 400-499 nm is (1.0-1.4): 1, and the number of the light quanta with the wavelength in the range of 700-780 nm accounts for 12-17% of the total number of the light quanta with the wavelength in the range of 380-780 nm. The light environment is used for indoor cultivation of lettuce, it can be guaranteed that purple and red vegetables with bright colors are obtained through production, and meanwhile the problem of yield reduction caused by coloring can be avoided. Besides, the light environment is within the visible light range, is harmless to the human body, is low in manufacturing cost and can be popularized in a large range.

Description

technical field [0001] The invention relates to the technical field of vegetable indoor cultivation, in particular to a light environment for indoor purple and red lettuce production. Background technique [0002] In recent years, with the rapid development of the field of plant lighting, there are many LED plant growth lights for indoor or greenhouse planting on the market. However, when planting purple and red vegetables indoors or in greenhouses with weak light, use normal LED plant growth lights are used as the source of light source. Purple and red vegetables can reflect the characteristics of purple and red vegetables at the seedling stage when the plants are relatively small and the leaves are relatively tender. The individual plants are larger or the leaves are longer and thicker. When they grow into adult leaves, the color of the leaves gradually fades from purple and red at the seedling stage to green, and the purple and red vegetables basically lose their original...
