LED plant auxiliary light
Plant factory definition:
An efficient agricultural system for high-precision environmental control in the facility for continuous crop production every year. It is a manpower-saving production in which temperature, humidity, light, and computer-controlled CO2 concentration and nutrition are automatically controlled by computers. Liquid, so that the growth of plants in the facility is not or rarely limited by natural conditions.
Definition of plant lighting:
After the birth of the plant factory concept, plant lighting came into being. What is plant lighting? Plant lighting mainly plays a role in complementing sunlight and regulating agricultural products.
Due to the considerable energy consumption of traditional factory lighting, LED and induction lamp lighting have been widely used in factories with the application of LED and induction lamp lighting technology in various fields. The led lamp is an electro luminescent semiconductor material chip, which is cured with silver or white glue to the bracket, and then connected to the chip and the circuit board with silver wire or gold wire, and sealed with epoxy resin to protect the inner core wire. The function is to install the outer casing, so the anti-shock performance of the LED lamp is good.
Plant lighting knowledge:
1. The effects of different wavelengths of light on plant photosynthesis are different. The wavelength of light required for plant photosynthesis is about 400-700 nm. 400-500 nm (blue) and 610-720 nm (red) contribute the most to photosynthesis.
2. is to use these two color combinations. The fleshy bulb has a wide range of wavelengths, which coincides with the spectral range of plant photosynthetic and photomorphogenesis; the spectral wave width is half-width narrow, and pure monochromatic light and composite spectrum can be obtained as needed; the light of a specific wavelength can be concentrated to illuminate the crop evenly; The flowering and fruiting of the crop can be adjusted, and the plant height and the nutrient composition of the plant can be controlled; the system has less heat and takes up less space, and can be used for the multi-layer cultivation stereoscopic combination system, realizing low heat load and miniaturization of the production space. In terms of visual effects, the red and blue plant light combinations are pink.
3. blue light promotes the growth of green leaves; red light is conducive to flowering and fruiting, prolonging the flowering period!
4. When plant light is used to supplement the plants, the height of the leaves is about 0.5 meters. The continuous irradiation for 12 hours and 16 hours per day can completely replace the sunlight.
characteristic:
1. Reduce cultivation costs and extend flowering period
2. Promote early maturity and yield increase of plants, improve the quality of fruits and vegetables, ensure the taste of greenhouse vegetables, and achieve anti-seasonal cultivation.
3. inhibit pest and disease reproduction, reduce the amount of pesticides, green pollution-free.
