According to Dr. Brande Wulff, leader of the research team, it usually takes 4-5 to six months for crops to harvest from seeds to harvests. By contrast, the team uses specially modified LED lights to grow crops, which takes only 8 weeks. In the Norwich Innis (John Innes Pew) Plant Research Center in the UK, the team is exposed to plants for 22 hours a day and provides a rich nutrient solution. But even so, they want to try to use more energy-efficient planting techniques than standard laboratories.
"We urgently need to develop crops that are better suited to the future climate, race against time and produce better crops," Dr. Wulff said. These new crops will be affordable, nutrient-rich and more productive varieties to help feed the world's growing population. ”
It is understood that these crops are also larger and healthier than those under normal growth conditions. The researchers mainly used led lamps to emit the blue and red light needed for photosynthesis in plants. Most laboratories and greenhouses use sodium steam lamps similar to streetlights.
Dr. Wulff points out that most of the yellow and green light emitted by sodium vapor lamps are not needed for plant growth, and LED lights can provide the light needed for plant photosynthesis.
However, the team's "fast-growing" technology cannot be applied to farms because of the unrealistic exposure to large farms at night. But Dr Wulff said the results were expected to accelerate crop research and produce crops with better adaptability, richer nutrition and less chemicals.
In addition, the team is trying to grow six generations of barley, peas and chickpeas in a year.
