Problems solved by technology
The artificial light sources used in agriculture and biology for a long time mainly include fluorescent lamps, incandescent lamps, sodium lamps, and dysprosium lamps. Among them, high-pressure sodium lamps and dysprosium lamps are light sources with high luminous efficiency and effective photosynthetic efficiency, but they consume a lot of power and emit spectrum. It cannot be well matched with the photosynthetic absorption spectrum of plants, and the efficiency of supplementary light is low; and it produces a lot of heat radiation, which cannot be close to the plants, and the light excitation efficiency for plant growth is not high, and the cost of artificial light sources is very high

Embodiment approach
[0026] ①Preparation of seedlings: Wrap the stem section of the purple cabbage with one leaf with a sponge, put it into the planting hole on the foam board, and culture it in nutrient solution until 4-5 true leaves are grown.
[0027] ②Illumination treatment: place the seedlings of purple back vegetables under the light-emitting diode (LED) with a combination of blue, red, yellow and green at a ratio of 7:1:1:1, and cultivate them in hydroponic culture in nutrient solution.
[0028] ③Condition control: In the light treatment stage, the light intensity is 55 μmol·m-2·s-1, the photoperiod is 12 hours, the cultivation temperature is 26-30°C, the humidity is 70±10%, and the cultivation time is 45 days.
[0029] ④ Control method: Light-emitting diode (LED) lamps provide light source, the light intensity is controlled by adjusting the number of lamps and the distance from the lamp to the plant canopy, and a timing device controls the photoperiod.

The invention discloses a gynura bicolor indoor producing technology by utilizing an LED light source, and belongs to the technical field of vegetables. A gynura bicolor stem segment with a leaf is wrapped by a sponge and then is put in a planting hole in a bubble plate, hydroponic cultivation is performed on the gynura bicolor stem segment with the leaf in a nutrient solution to be four to five true leaves, then, gynura bicolor seedlings are placed under LED with the blue, red, yellow and green combination of 7:1:1:1 for hydroponic cultivation in the nutrient solution for 45 days, and the LED light source with the blue, red, yellow and green combination of 7:1:1:1 is most suitable for growth of gynura bicolor. The technology has the advantages of being easy to operate, rapid and strong in plant growth, and environmentally friendly, saving energy and the like, and can be applied to the fields of industrial production of indoor rapid seedling culture, cultivation and sprouting of the gynura bicolor.
Description
technical field [0001] The invention relates to a technique for indoor production of purple-backed vegetables by utilizing LED light sources, and belongs to the technical field of vegetables. Background technique [0002] Hydroponic vegetables refer to vegetables whose roots grow in layers of nutrient solution and only provide water, nutrients, and oxygen through nutrient solution, which is different from traditional soil cultivation. Hydroponic vegetables have a short growth cycle and are rich in a variety of vitamins and minerals necessary for the human body. Purple back vegetable is a perennial herb of the Compositae family. It is cultivated sporadically in rural areas in southern China such as Guangdong, Guangxi, Hainan, Fujian, Yunnan, Jiangxi, Sichuan, and Taiwan. It has strong stress resistance, is basically free from pests and diseases, and has no pesticide pollution. Its twigs and leaves are crisp and tender for cooking, and have the special fragrance and unique f...
