What is the effect of LED plant growth lamp on the cultivation of greenhouse

Vegetable Greenhouse

         LED plant growth lamp on the greenhouse greenhouse planting effect: in the greenhouse use of LED plant lights, the effect is very significant, the growth rate of plants than the natural growth of plants almost three times faster. LED plant lights generally hanging from the leaves of the height of 0.5 to 1 meters or so, continuous exposure to 12 - 16 hours a day can completely replace the sun. In the winter without the sun, the use of LED plant lights and greenhouse, you can plant green vegetables, can improve the sweetness of fruits and vegetables and reduce pests and diseases, and increase the increase of 3 to 5 percent of the output.

Flower Greenhouse

        LED plant growth lamp is the use of the principle of sunlight, simulation of the plant for the growth of the necessary light environment of a lamp. Plant growth requires light for photosynthesis, but not all of the light is needed by plants. Planting plants with fluorescent lamps will find that plant growth is not ideal or even withered because light of different wavelengths for plant photosynthesis The effect is different, plant photosynthesis requires light, wavelengths around 400 to 700 nm. 400 to 500 nm (blue) and 610 to 720 nm (red) contribute the most to photosynthesis. The wavelength of the fluorescent lamp is about 1000nm (white) or more, no plant needs light, can not be normal for photosynthesis, plants can not be normal growth and development.

Planting Tools

        Blue (470nm) and red (630nm) LED plant lights, just to provide the necessary light plants. Blue light helps plant photosynthesis to promote green leaf growth, protein synthesis, fruit formation; red light can promote plant root growth, contribute to flowering results and prolong the flowering, play a role in increasing production. So the ideal choice is to use these two color combinations. In the visual effects, red and blue combination of plant lights appear pink. LED plant light red and blue LED ratio is generally between 4: 1 a 9: 1 is appropriate, usually optional 6 a 9: 1. Different plant growth requires a different ratio of light, such as stem and leaf plants need a little more blue, flowers and plants need a little more red.
