LED plant growth light: no sun, but long

"LED plant growth lamp is a kind of light fixture that uses LED (light-emitting diode) as a light source instead of sunlight to provide photosynthesis for plant growth. It controls the plant morphology through light quality adjustment, shortens the flowering result of plants, and makes plants more water and nutritious value. Higher, He Yanliang, technical engineer of greenhouse greenhouse in Qinlong Modern Ecological Intelligent Creative Agriculture Park, said that LED plant growth lamps are an important technology in the field of facility vegetable cultivation. “Without the sun, it grows pretty.” He Yanliang explained that vegetable growth only absorbs red-orange and blue-violet light in sunlight, and the utilization of light energy is low, which is greatly affected by the natural environment. The LED plant growth lamp can adjust the spectrum according to the type of vegetables and the needs of the growth stage. The plant leaves have more blue light and the flowering result is more red. Lettuce, which originally took 50 days to 60 days to grow, can be matured in just 20 days using LED plant growth lamps.

Xu Zhigang, a professor at the Agricultural College of Nanjing Agricultural University, said, “LED plant growth lamps are factory-based seedlings, which are more advantageous than traditional light sources. Traditional light sources require 0.5 kilowatts of light per square meter, while LEDs require only 0.27 kilowatts, which can reduce power consumption. half". He believes that LED plant growth lamps still have a large extension space, which can be used for physical control of agricultural pests, killing pests with LED light sources of specific wavelengths.
