Vietnamese scientists are trying to create LED lamp
products which have the light spectrum suitable with every kind of
plant, which can help save electricity, churn out clean and off-season
products.
Use
LED lamps in the farm would bring higher biology energy efficiency.
Thus allowing to better stimulate the growing of the plants than other
familiar lamps. Especially, LED lamps would help save electricity. And
you will pay less for the electricity bills.
Fluorescent lamps used in tissue culture would consume 30 – 40
percent of electricity, and 82 percent in the plant breeding
enterprises. Meanwhile, with LED lamps, the volume of power to be
consumed would be much lower. At plantation enterprises, if using LED
lamps, one square meter of plantation area would need 0.27 kwh of
electricity, while it would need 0.5 kwh with other kinds of lamps.
Scientists have also affirmed that the use of LED lamps in
agriculture production would help improve the quality of farm produce,
increase the nutrition value and reduce the nitrate concentration in
vegetables and fruits. This also allows creating clean off-season
products with high economic values. The experiments have shown that
after a short period of lighting with LED lamp, the toxic nitrate
concentration has reduced to 44-64 percent.
And LED lights
would produce less heat radiation than high-pressure sodium lamps,
allowing the photosynthesis process to occur more intensity to reduce
the concentration of nitrate, lasting just a short period instead of the
whole growth cycle.
Now, China, South Korea, Japan and the US have invented in utilizing
LED lights in agriculture production. Meanwhile, Vietnam is just at the
very early phase of utilizing LED lamps. However, scientists have
reminded that the LED lamps needed could be different in terms of the
light spectrum, the B/R ratio, the lighting intensity and duration,
depending on the different stages of the plants’ development.
The only barrier in using LED lamps is the high production costs of
the lamps, but the barrier would be removed in the future because of the
LED’s advantages.
