The light environment is one of the important physical environmental factors indispensable for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of facility cultivation.
LED plant growth lamp is a kind of lamp that uses LED (light-emitting diode) as the light source, must use sunlight according to the law of plant growth, and replace the sunlight with light to plant growth and development environment.
LED plant lights help to shorten the growth cycle of plants, because the light source of this lamp is mainly composed of red and blue light sources, using the most sensitive light band of plants, the red wavelength is 620-630nm and 640-660nm, and the blue wavelength is used. 450-460 nm and 460-470 nm. Let plants promote the differentiation of multiple collaterals and buds during the growth process, accelerate the growth of roots and leaves, accelerate the synthesis of plant carbohydrates and the synthesis of vitamins, and shorten the growth cycle.
The results of a large number of applications of LEDs in plant cultivation environments indicate that LED plant lights are particularly suitable for use in artificial light-controlled plant facility cultivation environments.
The color temperature and lumen of the artificial light source are seen by the eyes of the creature, and the plant's demand for light is the photosynthesis. This is determined by the radiation value without looking at the color temperature and lumen.
