Plant growth light is a light source used to grow plants. It is mainly used for planting and management of crops and flowers. It can generally be divided into three types: red light, blue light and green light.
Red light is the red light spectrum in the visible spectrum, which is suitable for photosynthesis and can promote the chlorophyll of plants; blue light is a kind of monochromatic light, which can produce a large amount of anthocyanins; green light is a special Spectrum, usually yellow and green.
The plant growth light can increase the chlorophyll content of the plant and promote the photosynthesis of the plant in a certain concentration of nutrient solution. It can promote the enlargement of leaf cells; make the leaves shiny, brightly colored, and thick stems; make crops grow robustly, reduce diseases and insect pests, etc.
It is mainly used in the planting management of vegetables, flowers, etc., which is very helpful for increasing production.
What is light?
The speed of light is the speed of light. The amount of light passing through a unit area in a unit time is called the speed of light. Light has three important characteristics: directionality, a long-term change rule, energy dissipation.
On Earth, everything has a certain size and shape, a certain wavelength and different brightness, and they transform into each other in space. The energy of different lights is related to the wavelength: light of one color (red light) contains the most energy; followed by blue, red and blue light, among which red light contains the least energy; white, blue and yellow light contains the least energy.
What are the functions of a plant growth light?
- By improving photosynthesis, increasing photosynthetic products, improving plant stress resistance, and promoting yield increase.
- By improving the absorption of nutrients, promote root development, enhance plant resistance, and reduce diseases.
- By adjusting the stomatal opening of the leaf and the change of the leaf structure (that is, changing the stomatal opening; increasing the thickness of the leaf) to achieve the purpose of light regulation;
- Regulate photosynthesis by adjusting the sensitivity of plants to light intensity.
Common types
In general, plant growth lights are mainly divided into three categories:
Yellow light: mainly used for the production of vegetables and other plants, which can increase the light and promote growth during the vegetative reproduction of plants;
Purple light lamp: that is, incandescent bulb, which can be used for indoor greening and flower cultivation management;
Strobe light: it is a new light source that has only appeared in recent years.
Choose
- Choose according to the application needs: such as flower cultivation, seedling cultivation, etc.
- Select by function: mainly used for photosynthesis and other functions.
- How to use: According to different needs, choose different photoperiods and light colors to regulate the light of plants to achieve the desired effect.
