1.Effects of red and blue light on plants:
Red light: promotes the growth, germination, flowering and fruit of plants, plays the most leading role in the color enhancement of plants, promotes the photosynthesis of plants, and is more suitable for flowers, fruits and vegetables greenhouse to supplement the light.
Blue light: it can enhance the activity of chloroplast and prevent the plant from growing out, but on the other hand, it can inhibit photosynthesis, which is suitable for succulents, stem and leaf species, seedlings of all plants, dendrobium officinalis and other plants.
Red light and blue light are recommended! Can be customized according to customer requirements.
Long sunshine plants: during the growth and development of plants, it takes more than 14-17 hours to germinate. The longer the light lasts, the earlier the flowers bloom. For example: wavelength, radish, cabbage, lettuce, rape, osmanthus, cuckoo.
Intermediate plant: during the growth and development of plants, there are no strict requirements on the length of light, such as pepper, bean, clivia, tomato, cucumber, clivia.
Short-day plants: plants need 8-12 hours of sunlight during their growth and development, such as strawberries, thousands of cows, chrysanthemums.
The wavelength types are abundant and coincide with the spectral range of plant light synthesis and light morphogenesis. The spectrum wave width is half wide and narrow, which can be combined to obtain pure monochromatic light and composite spectrum according to needs. It can focus light at specific wavelengths on crops evenly; It can not only regulate the flowering and fruiting of crops, but also control plant height and plant nutrients. The system has low heat and small space, which can be used in multi-layer cultivation stereoscopic combination system, realizing low heat load and miniaturization of production space.
Sunlight is essential for plant growth in addition to nutrients and water. But as every grower knows, daylight is out of control. As a result, artificial daylight is gaining acceptance in horticulture because it can artificially control the growing season and completely shorten the growing time of plants.
For the following purposes:
(1）. As a supplementary source of light, it can be enhanced at any time of the day so as to always help plants with photosynthesis. Especially during the winter months, it can extend the effective lighting time.
No matter at dusk or night, it can effectively extend and scientifically control the light needed by plants, and it is not affected by any environmental changes.
(2), in the greenhouse or plant laboratory, can completely replace the natural light, to promote the growth of plants.
For most growers, plant sodium and metal halide lamps are the best alternatives to sunlight. Metal halide lamp rich in blue light is suitable for the growth of early plant branches and leaves.
