What's the advantage of using plant growth lights in greenhouses?
The blue (470nm) and red (630nm) LED plant lights just provide the plants with the light they need. Blue light can help plant photosynthesis, promote green leaf growth, protein synthesis, fruit formation; red light promote the growth of plant roots, help flowering and flowering, and play a role in increasing yield. Therefore, the ideal choice is to use the two color combinations. In the visual effect, the combination of red and blue lights appear pink. LED plants light red, blue, LED ratio is generally between 4:1 and 9:1 is appropriate, usually optional 6 9:1. Different plants need different light ratios, such as stems and leaves, which require more blue light, and flowers and plants need a little more red light.
The LED plant light is a lamp that simulates the light environment necessary for plant growth by using the principle of sunlight. Plants need for photosynthesis, but not all the light is needed for plant, using fluorescent lamps plant, will find that plant growth is not ideal even wither, this is because the influence of different wavelengths of light for photosynthesis is different, the photosynthesis of plants need light in a 400 wavelength about 700nm. 400 500nm (blue) light and 610 720nm (red) contribute most to photosynthesis. The fluorescent light is about 1000nm (white light) above, no plants need light, can not be normal photosynthesis, plants naturally can not normal growth and development.
The effect of LED plant growth lamp on greenhouse cultivation: the effect of using LED plant lamp in greenhouse is very remarkable, and the growth rate of plant is almost 3 times faster than that of natural growth plant. LED plant lights are generally suspended from the blade height of 0.5 to 1 meters, continuous irradiation for 12--16 hours a day, can completely replace the sun. In the winter without sunlight, using LED plant lights and greenhouse can grow green vegetables, which can improve the sweetness of fruits and vegetables, reduce pests and diseases, and increase the yield from 3 to 5.
