The role of plant lighting LED plant lights on the growth of plant stems and lea

The effect of light on the growth of plant leaves:

Experiments have shown that: over a period of time, the growth rate of leaves (leaf size) is almost as fast in the dark as in the light;
 
In another time period, the value of leaves in the light grows faster than the leaves of plants in the dark, especially for dicotyledonous plants;

Ultimately, there was little difference in leaf size in bright light versus in the dark.
 
That is to say, in the process of plant leaf growth, the role of light is mainly to accelerate the differentiation rate of cells, and the elongation of cells in leaves is faster than that in the dark.
 
It is often said that LED grow lights can shorten the growth cycle of plants and allow crops to be marketed in advance. In fact, from the perspective of increasing light intensity and light time, it can speed up the differentiation rate of plant leaf cells, thereby shortening the process of plant maturity.

Effects of light on plant stem growth:

In daily life, we will find that staring at plants during the day does not see any difference from morning to night, but when we wake up and look at our beloved crops, we find that they have suddenly risen a lot.
 
In fact, the speed of plant elongation at night is greater than that in the daytime. This is because light promotes plant growth, mainly to promote plant photosynthesis to accumulate organic matter for the use of plant growth and respiration at night. In fact, during the day, light will also inhibit the growth of plants. Growth, especially blue light, had the strongest inhibitory effect on plant stem growth.
 
Red light has a promoting effect on the elongation of plant stems. Under sunlight, the promoting effect of red light on plant stems is almost the same as the inhibitory effect under blue light. Therefore, it is not that our eyes cannot see the subtle growth of plants, but plants The growth rate is too slow.

When we buy LED plant lights, we will find that the ratio of red and blue lamp beads is 7:1/8:1, etc. The reason for this setting is because:
        (1) The demand for red light in plant photosynthesis is the largest, and a larger intensity of red light is required to meet the growth needs of plants
        (2) Less blue light bead ratio can already meet the needs of plant growth
        (3) When using LED plant lights, the red light is greater than the blue light, and the plants will still grow relatively fast at this time.
        (4) The inhibitory effect of blue light on plants will lead to strong plant growth
        (5) Red light will promote plant elongation

Therefore, the settings of LED plant lights are set through practice, summarizing the growth characteristics of most flowering and fruiting plants or stem and leaf harvesting plants, so as to ensure that the plants are in the best growth state.
 
Red and blue light are not only the effect of promoting flowering and stem and leaf growth respectively, so they affect the final effect and main effect of plants.
 
Light is of great significance to the entire biological world. The myriad changes in nature are always breathtaking, and the infinite mysteries make people unable to stop exploring her. Constantly understanding and exploring will allow us to get along with nature. more harmonious.
