The question about the ratio of LED plant lamp beads is the question most asked by buyers during consultation, and it is also the most difficult question to answer, because there are many types of plants, which can be divided into positive plants, negative plants, and shade-tolerant according to the degree of light required. Plants can be divided into long-day plants, short-day plants, medium-day plants, and intermediate-type plants according to the light time required. Take flowers as an example, according to their functions, they can be divided into flowers with foliage, flowering, and fruiting. , There are succulents, some grow up and then bloom, some bloom first and then grow leaves.
In this way, each plant must have a tailor-made supplementary lighting program for each growth period, whether it is research from various countries in the world, or major plant breeding and planting companies or LED plant lighting plant lighting service providers, parameters in this regard They are all still in the process of research, and their data is not perfect. And the parameters can only be used as a partial reference, and the specific application needs to be considered comprehensively with other local factors at the time. Therefore, it is difficult to answer exactly which plant is suitable for which configuration.
At present, the most reference scheme is based on the ratio of sunlight spectrum, which can be flexibly adjusted according to the field planting situation and crop types and functions. The ratio of red to blue light of sunlight is about 6-8:1. Use this as a reference for flower viewing. Or leafy vegetables, the configuration is 6-8:1 or less, let the blue light be a little bit more, because the blue light is conducive to the growth of plant leaves. For flower viewing, choose 6-8:1 or more for supplementary light during the flowering period, and let the red light be more, because the red light is conducive to the flowering and fruiting of the plant. From seedlings to flowering, the whole growth period needs to be filled with light, just choose 6-7:1.
In addition, please note that the same plant has different requirements for light quality and light quantity in different growth periods. It is sufficient to use cheaper LED plant lights during the seedling period. Generally, LED plant light strips can be used, or appropriate Reduce the number of lights on high-power plant lights (group-controlled LED plant lights are more expensive), and use high-power LED plant lights when the plants are blooming, so that the crops can grow with the fastest growth rate and the best quality .
