Why the LED plant light can shorten the plant growth cycle
Light quality, light intensity, light time together determine the plant's growth cycle.
Plant Growth In open-air nature, each plant has developed its own photoperiod gene, but their true growth potential has not been fully exploited due to a variety of natural and uncontrollable factors. LED plant lights bring plants from the outdoors Indoor, a variety of growth conditions can be completely manual control, completely activate the growth of plant cells, through the LED plant light regulation of plant photoperiod, thus affecting plant growth.
First of all, plants and people like the need to exercise, need work, but also need to rest, so use LED plant lights to make up when the plants have to control the time, it is generally recommended that plant light control between 12-16 hours, so Allow enough time for the plants to rest in order to ensure the efficiency of plants working on a daily basis.
The quality of light has a significant impact on the growth of plants in various periods. For example, flowering plants need sufficient red light during flowering and fruit setting, and if the red light is not enough, the light intensity will not reach the desired effect. Affect the flowering rate of plants, if you can according to the needs of plants, plant a variety of light in proportion to complement the plant light, the effect will be completely different, not only can shorten the plant growth cycle, but also improve plant yield and quality. This is also the reason why plant lights appear, but also the reason that LED plant lights replace traditional plant growth lights.
At present, plant lighting LED plant growth lamp beads are mainly red light bead, blue light bead, white light bead and full spectrum light bead, the reason why the light beads of these spectra is because countless experiments prove that plant growth is most needed Of the light is the red and blue light, LED plant light white light beads is to supplement plant growth may need other spectral components, full spectrum LED plant light lamp beads emitted mainly red and blue light, light on the callus Luring and organ differentiation also have a significant impact, the red flowers play a particularly important role in plant flowering time.
Time and light quality are reasonable circumstances, you need to use LED plant light control light intensity. Studies have shown that light intensity on plant cell proliferation and organ differentiation have a very important impact, which is the plant's growth has a very important impact, different light intensity affects the plant growth in all stages, the plant growth does not need too early Of the light to meet the needs of plant germination and growth can be, with the growth of plants, light intensity to be appropriate to increase the robust nurturing seedlings are very important, plant flowering results, LED plant lighting directly affects the flowering and fruit The rate also determines the yield and quality of this plant.
If the light intensity is not enough, the photosynthesis and respiration of plants can’t even maintain a level of peace, and even plant growth is even more impossible, if the light intensity is too strong, more than the light saturation point is purely a waste of energy, there is no need, So the most ideal state is to control the light intensity around the light saturation point, so that plants can be healthy to the fastest growth.
So the determinant of the light in a plant's growth cycle can be measured by the following formula:
Plant growth cycle = light intensity + light time + light quality
LED plant light is very good to meet the above three light conditions, which can shorten or mediate the plant growth cycle.
Different plants require different light formulations for their growth and development. Therefore, appropriate measurement techniques and instruments are needed to accurately measure the optical parameters of the light environment to determine whether they meet the growth requirements of the plants and select the appropriate light source for the plants to grow more perfect.
In view of the general spectrophotometer can’t meet the requirements of plant lighting measurement of the status quo, in order to solve industry problems, Far EasTone introduced a special measurement of plant lighting for the measurement and analysis of professional measurement equipment - PLA-20 plant lighting dedicated analyzer Is based on spectrometry to measure, can be widely used in plant plants, soilless cultivation, greenhouse plants and other plants in the field of light radiation monitoring, such as plant growth in the light analysis, monitoring, research and exchange.
PLA-20 can’t only measure parameters such as general illuminance, irradiance, chromaticity coordinates, color temperature and color rendering index, but also accurately obtain photosynthetic photon flux density, photosynthetic radiation irradiance, chlorophyll A / B weighted irradiation Degree, far red light irradiance and other parameters.
