The supplementary light of LED grow lights is simulated according to the effect of solar photosynthesis, which can prolong the photosynthesis of grows. Regardless of the geographical season, it can fill light at any time to give grows a more ideal growth state. Then, what impact does LED grow light have on grows when it fills up light?
1. The influence of LED grow light on grow organ differentiation
The differentiation rate of grow organs under the white light of LED grow lights is fast, especially the differentiation rate and biomass of grow buds are high, but the root differentiation rate is inhibited. The root differentiation rate under the red light of LED grow lights is fast and the root differentiation rate. The blue light of LED grow lights improves the chlorophyll content and biomass. Different spectra have different effects on grow organ differentiation.
2. The effect of LED grow light on the growth of grow stems
The blue light of the LED grow light has a significant inhibitory effect on the hypocotyls, and increasing the irradiation can reduce the grow height. The red light of the LED grow light obviously inhibits the elongation of the hypocotyl and reduces the free auxin content of the hypocotyl, which may be caused by the promotion of the transformation of free auxin to bound growth cord.
3. The influence of LED grow light on the photosynthetic characteristics of grows
LED grow lights have a regulatory effect on the synthesis of chlorophyll. Phytochrome a and phytochrome b have a direct effect on the synthesis of chlorophyll. Cryptochromes also have a certain effect. Leaves under red light have higher chlorophyll content and lower chlorophyll content. The ratio of chlorophyll a to chlorophyll b is suitable for supplementing light to negative grows. Chlorophyll a and chlorophyll b have the highest values under blue light, which is suitable for supplementing light to positive grows. Increasing blue or red light irradiation can significantly increase the photosynthetic rate.
The actual role of LED grow lights
1. Promote grow photosynthesis
2. Shorten the growth cycle of grows
3. 10-20 days in advance
4. Increase production and income by 20%-79%
5. Promote flowering
6. Improve fruit set rate
7. Deworming and disease resistance
8. Reduce malformed fruits
9. Improve the taste, quality and appearance of the fruit
Why is there more red light than blue light in LED grow lights?
The ratio of red to blue of LED grow lights is matched with the ratio of lamp beads according to the grow's demand for light, but generally the red lamp beads are a little more, because the grow needs more red light than blue light.
There is a reason to say that grows need more red light than blue light. Let’s analyze it together below:
During the growth of grow stems, compare the sunlight and the red light of LED grow lights. The content of chlorophyll under the sunlight is from low to high. The chlorophyll content of LED grow lights under red light is always higher than that under sunlight, because sunlight contains different spectrums, which also shows that the red light of LED grow lights makes the formation of chlorophyll faster, which is proportional to the passage of time.
The growth of grows under the red light of the LED grow light will be better, because the red light of the LED grow light makes the formation of chlorophyll faster and more carbohydrates are synthesized, providing enough energy and material for the grow to grow.
The NR activity in the stem under the red light of the LED grow light is significantly greater than that under the natural light, and the red light of the LED grow light greatly promotes the flowering and fruiting of grows;
The red light of LED grow lights can promote the formation of chlorophyll, the accumulation of carbohydrates and the absorption and utilization of it, which helps grows to bloom and bear fruit. Blue light mainly prevents grows from growing, promotes the formation of grow dry matter, and has obvious effects on the synthesis of grow protein and fat.
The result obtained above is that in most grows, the effect of red light is obvious. The red light of LED grow lights is a little more than blue light, but not all grows are like this, so the spectrum required by grows is still customized.
