The use of LED plant lights is coordinated with the light saturation point and light compensation point of different plants. The light saturation point and light compensation point of plants vary with crop types and cultivation conditions. Some negative plants reach light saturation in less than 10,000 lux, while positive plants require tens of thousands of lux to reach saturation. Some four-carbon (C-port plants) are often not fully saturated when exposed to direct sunlight at noon (about 100,000 lux). Generally, the light saturation point of three-carbon (Ca) plants is lower than that of four-carbon (C,) plants. Below. Just list the light compensation points and light saturation points of several common crops:
LED plant lights are selected according to the light saturation point
It can be seen from the above that if plants are growing due to lack of sunlight in the environment, such as basements and balconies, they are planted. Artificial light (plant light) needs to be used to replace sunlight to provide the energy required for photosynthesis for plant growth. The light intensity of the required light source must reach the light compensation point required by the plant to grow normally.
Below the light compensation point, the plant grows extraordinarily or grows slowly; above the light saturation point, the photosynthetic rate no longer increases, and light inhibition occurs, resulting in a waste of light energy. The light intensity is between the light saturation point and the light compensation point. The use of led plant growth lights to grow fruits and vegetables can promote plant photosynthesis and shorten the growth cycle. It can be marketed for 10-20 days in advance, increase production and income by 20-80%, and promote flowers. Fruit, improve fruit setting rate, deworming and disease resistance, reduce deformed fruit, improve the taste, sweetness, quality and appearance of the fruit. This is why the use of plant growth lights has no effect. If the temperature, humidity, water, fertilizer, and carbon dioxide concentration are normal, the biggest reason is that the light intensity of the LED plant lights is lower than the light compensation point of the plants. There are two reasons for low light intensity:
1. The luminous intensity of the LED plant light itself is low, and the solution needs to be replaced or increased.
2. The LED plant light has high luminous intensity, but the distance between the light and the plant is too high, so that the light intensity reaches the surface of the leaf and is lower than the light compensation point of the plant. The solution is to reduce the height of the luminaire.
Hooyi Energy-saving specializes in the production of LED plant lights, which can give you the most professional spectrum matching and the best cost-effective plant lights for the crops you are planting, so as to satisfy you with the lowest cost of using led plant lights and the greatest economic benefits.化.
The strength of photosynthesis of any kind of crop is closely related to the intensity of light. The trend of photosynthetic intensity changing with the intensity of light is similar. When light is increased, photosynthesis increases, and when light is weakened, photosynthesis decreases. But when the light is increased to a certain extent, the photosynthetic intensity will no longer increase, and the light intensity at this time is the light saturation point of photosynthesis. When the light is weakened to a certain limit, the photosynthetic intensity cannot be measured (the photosynthetic intensity and the respiratory intensity are exactly equal, the ratio is 1), and the light intensity at this time is called the photosynthetic light compensation point.
