Is the plant growth lamp useful? Today Xiaobian shares it with friends.
Answer: Certainly useful;
Everything growth lamp depends on light, we all know the process of plant growth needs: water, fertilizer, light, gas, heat, indispensable, the only five elements of light is beyond our control, so many grower friends began to look for plant growth lamp-related products, so that their greenhouse crops can grow rapidly and improve economic efficiency.
Here, Xiaobian tells you that there are many manufacturers of plant growth lamps in the market. It shows a problem that plant growth lamps are certainly helpful to plants. So as users, how can we choose a reliable plant growth lamp? Right, overvalued and wrong, of course, it is not only a loss of money, but also a blow to our letter. Heart, so choose a plant growth lamp manufacturer, decide whether your plant growth lamp is useful.
Xiaobian to popularize the spectral requirements of plants, different spectra produce different results!
Effects of Spectral Range on Plant Physiology
280-315 nm-with minimal effect on morphology and physiological processes
315-400 nm-less chlorophyll absorption, affecting photoperiod effect and preventing stem elongation
400-520 nm (blue) - chlorophyll and carotenoid absorption ratio is the largest, which has the greatest impact on photosynthesis.
520~610 nm (green) - Pigment absorption rate is not high
610-720 nm (red) - chlorophyll absorption rate is low, which has a significant effect on Photosynthesis and photoperiodic effect.
720-1000 nm - low absorption, stimulating cell prolongation, affecting flowering and seed germination
> 1000 nm - converted into heat
From the above data, the effects of different wavelengths of light on plant photosynthesis are different. The light needed for plant photosynthesis is about 400-720 nm. 400-520 nm (blue) and 610-720 nm (red) which contribute the most to photosynthesis. 520-610 nm (green) light is absorbed by plant pigments at a very low rate.
According to the above principles, plant lights are made into red-blue combination, all-blue, all-red three forms, to provide two wavelengths of red-blue light, covering the required wavelength range of photosynthesis. In visual effect, red-blue combination of plant lights show pink.
Finally, Xiaobian tells you that after years of customer feedback, using plant growth lamps, you can make your crops:
1. It is not a problem to let crops go on the market 7-30 days in advance.
2. There is no problem in increasing the yield of greenhouse crops by more than 35%.
3. Preventing fog and haze effectively, preventing and eliminating harvest, reducing our risk;
4. Effective resistance to pests and diseases, reducing pesticide intake;
5. Our laser plant growth lamp needs only three kilowatt-hours of electricity a month.
6. Our laser plant growth lamp only needs one lamp per mu of land.
7. Effectively improve the quality of agricultural products (sugar content increased by more than 3 points);
