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

[0032] ① Seed germination: select broad bean seeds of the same size and soak them in clean water for 24 hours. After the seeds are taken out, they are evenly ordered in a seedling tray with 4 layers of absorbent paper on the bottom for accelerating germination, and the cotyledons are flattened after 8 days.

[0033] ②Light treatment: The broad bean seedlings with flattened cotyledons are cultivated under the monochromatic red light and blue-red combined light (B:R=6:4) of the rare earth plant growth lamp.

[0034] ③Condition control: the light intensity is set to 3000 lux, the photoperiod is 12 hours, the culture temperature is 25±1℃, the humidity is maintained at 70±10%, and the culture is 10 days.

[0035] ④Control method: The light intensity is controlled by adjusting the number of lights and the distance between the lights and the canopy of the plant, and a timing device controls the light cycle.

[0036] 3. Implementation effect

Abstract

The invention discloses a technology for culturing a fava bean sprout by the adoption of artificial light source, belonging to the technical field of biology. Fava bean seeds with a same size are selected, the seeds are soaked firstly and then taken out for drying, and the seeds are placed in a sprout culture disc for germination. After cotyledons are unfolded, the sprout culture disc is placed in monochrome red light and blue-red combined light until the sprout grows. The monochrome red light and blue-red combined light (B:R=6:4) is most suitable for the growth of cabbage type rape sprout. The technology has the advantages of simpleness in operation, energy saving, environment friendliness and the like, and can be applied in fields of indoor rapid growth, industrial sprout culture and the like for the fava bean sprout.

Description

technical field [0001] The invention relates to a technique for cultivating broad bean sprouts by using artificial light sources, and belongs to the field of biotechnology. Background technique [0002] At present, the light needed for the production of broad bean sprouts is all provided by sunlight, but there is no report on cultivating sprouts with artificial light sources in a closed state without sunlight. At present, my country's aircraft carrier and space flight must consider the problem of the supply of vegetables and non-staple food for personnel. Adopting artificial light source to cultivate sprouts is one of the effective ways to solve the above problems. [0003] Light is one of the most important environmental factors affecting plant growth and development in nature. It has regulatory effects on plant growth and development, morphogenesis, photosynthesis, material metabolism and gene expression, and also acts as an environmental signal to regulate the entire lif...
