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 Construction

[0015] The methods used in the following examples are conventional methods unless otherwise specified, and the percentages are volume percentages unless otherwise specified.

[0016] First carry out LED irradiation to black soybean (kind of production) with the method of the present invention, comprise following three steps:

[0017] 1) Preparation of seedlings: select plump black soybean seeds of the same size, wash them in running water for 1-2 hours, and then soak them in clean water for 16 hours. After taking out the seeds, evenly sow on demand in a seedling raising tray with 2 layers of newspapers at the bottom, 50 cm long, 40 cm wide, and 8 cm high, to germinate, and the cotyledons are flattened after 6-7 days.

[0018] 2) Light source treatment: Place the flattened cotyledons of black soybean seedlings under a combination of blue, red and yellow light (B:R:Y=5:3:1) for cultivation. The light intensity is set to 35 μmol m -2 ·s -1 , the photoperiod is 12 hours, the cu...

Abstract

The invention discloses a light source control technology for indoor culture of black soybean sprouting vegetables, and belongs to the technical field of biology. The light source control technology comprises the following steps that full black soybean seeds in uniform size are selected and are firstly placed into a seedling culture disc for germination acceleration; after the cotyledon grows flatly, the seedling culture disc is placed under a blue, red and yellow combined light LED (light emitting diode) to be cultured until the sprouting vegetables grow up. The blue, red and yellow combined light (B:R:Y=5:3:1) is most suitable for the growth of the black soybean sprouting vegetables. The light source control technology has the advantages that the operation is simple, the energy sources are saved, the environment is protected, and the like. The light source control technology can be applied to the fields of indoor fast production, factory seedling culture and the like of the black soybean sprouting vegetables.

Description

1. Technical field [0001] The invention relates to a light source control technology for indoor cultivation of black bean sprouts, and belongs to the field of biotechnology. 2. Background technology [0002] The illumination needed for the production of sprouts of black beans is all provided by sunlight or fluorescent lamps, but there is no report yet on utilizing LED artificial light sources to cultivate sprouts of black beans. [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 life cycle of plants. . The 21st century will be the century of ecological agriculture, and optical application is one of the main ways to realize ecological agriculture. How to increase the specific artificial light source under the condition...
