Strength-adjustable color-mixed LED vaccinium uliginosum tissue cultivation light supplementing device

Abstract

The invention relates to an LED plant lighting device. The device comprises a lampholder, a lampshade, LED rotary knob strength adjusters and a constant current source circuit. The surface of the device is provided with a layer of LED light source module, the module comprises a rectangular aluminum base plate, twenty groups of LED light supplementing light bars are attached to the aluminum base plate, ten of the light bars are red light bars with the wave length being 600-665 nm, and ten of the light bars are blue light bars with the wave length being 425-495 nm, and the red light bars and the blue light bars are arranged in a spaced manner. The interval between LED lamp bars in the light bars is 7 mm, and the lamp bars are connected to the constant current source circuit through corresponding wires after being connected in parallel; and two LED light source controllers are arranged to control the strength of the red LED light and the blue LED light correspondingly. Adjustment can be performed according to requirements on light at different stages of vaccinium uliginosum tissue cultivation seedlings, in the multiplicative stage, germination of overgrowing branches is promoted, the multiplication coefficient is increased, and radial thickening of the overgrowing branches is achieved; and in the rooting cultivation stage, rooting time is shortened, the root system activity is improved, strong seedlings with large stems and thick roots are obtained, accumulation of bio-active substances, such as saccharides and anthocyanin, is improved, comprehensive resistance of the seedlings is improved, and the transplant survival rate is increased.

Description

[0001] Technical field: [0002] The invention relates to an LED plant supplement light lamp, in particular to a mixed-color LED Duss bilberry tissue culture supplement light device with adjustable light intensity. [0003] Background technique: [0004] Vaccinium uligiosum Linn. is a deciduous shrub of the Rhododendron family Vaccinium vulgaris. It is extremely cold-resistant. It is concentrated in the Daxinganling and Changbai Mountains in China. It is one of the wild berry resources with great development and utilization value, commonly known as wild blueberry. . Its fruit is blue-purple, rich in a variety of active substances, and has high nutritional and health value. It is listed as one of the five major health foods by the International Food and Agriculture Organization and has important protection and development value. The artificial cultivation of Bilberry has not yet been realized, and its seedling breeding is the key limiting factor. Compared with the mature tissue cult...

Problems solved by technology

Bilberry has not yet been cultivated artificially, and its seedling breeding is the key limiting factor

Compared with the currently matured cultured blueberry tissue culture technology, the main problems of the tissue culture of Dusi lingonberry (wild blueberry) are: although the multiplication coefficient is high, the stem is thin and thin, the leaves are narrow and small, the root system of rooted seedlings is weak, and the aerial roots After transplanting out of the tissue culture environment, they usually cannot adapt to the external environment and die, and the survival rate of transplanting is extremely low

[0005] The light source is one of the most important environmental factors in plant tissue culture. At present, the mainstream light source for tissue culture is white fluorescent lamp as an artificial light source, and the energy-efficient light emitting diode (Light Emitting Diode, LED) light source is gradually used in plant tissue culture. , but the adaptability of plants to light is very different, and there is no research on the adaptability of bilberry to light source at present.
