It is reported that a few days ago, the British Pulaisi announced a horticultural LED lighting test results of lilies, the test was carried out in the Together2Grow lily flower growers Poeldijk, a village in the south of the Netherlands. It is reported that Together2Grow and Plesay cooperation LED lighting as a greenhouse high pressure sodium lamp lighting aids, and the greenhouse is used to grow virginia species of lily. Test results show that, with the help of 7 weeks of solid-state lighting, lily yield increased by 20%.
It is understood that lily, also known as narcissus lily, yellow six flowers or parrot lily, produced in South America, is now all over the world. Plessey has previously announced several gardening lighting tests, one of which tested tomatoes. In all cases, solid-state lighting is used as a secondary source of energy for plants.
It is understood that the test range control in the existing high pressure sodium lamp lighting environment, and high pressure sodium lamp can provide 70 靘 oles / m2 / sec light quantum flux density (light intensity), solid state lighting test, each 1000W next to the installation of high pressure sodium lamp With seven Plessey Attis LED lamps, the optical quantum flux density increased to 130 oles / m2 / sec.

Test results show that in the solid-state lighting environment, the output of flowers increased, and opened more lush. Together2Grow co-owner Bernard Zuidgeest said: "For now, I am very satisfied with the results of the experiment, under the LED lighting conditions, the plant looks more lush and healthy, and the yield has also increased.Only more light without additional Of the radiant heat that plants can still maintain at normal plant temperature We are working with Precel to test more plant varieties and turn the greenhouse into a hybrid lighting system "
In addition to a 20% increase in yield, lilies under LED horticultural lighting grew an average of 2 grams per stem. It is reported that, LED lighting system combines far infrared, super red and blue LED. Plessey said the efficiency of LED lamps is 40% higher than that of high-pressure sodium lamps.
