Danish KnudJepsen breeding company to cultivate longevity Flower Queen series (High cold dish) It is famous that the company has made an improvement. On the premise of not building a new greenhouse, it has increased the production area of the Longevity flower Queen series, this attempt is only achieved by installing an LED light supplement module in the transition area of the seedling. KnudJepsen breeding company is a world-renowned breeder and producer of the Danish longevity Flower Queen series, located in hinakup, Denmark (hinnercup). The production area of the company's facilities reaches 120 thousand square meters. High automation and good operation efficiency are important secrets of the company's success. After continuous exploration, new production technologies are constantly emerging. The company cooperated with Philips electric appliances three years ago on the potential possibility of applying LED lighting fill-in technology to the company's Queen series Longevity flower production. The company has gradually tried to use the company's research and development manager, kayiluni, in the production process, said: according to the small-scale experiments in the laboratory, different types of LED light sources have obvious good effects on the growth of longevity flowers. At the same time, he also announced a test result of using only LED light sources for the growth of longevity flowers. The two test results clearly show that LED light supplement technology is feasible, but it needs to be widely promoted to determine the reliability of its use. The company plans to install Philips LED light supplement modules in every link from the seedling transition area to the seedling raising in the next step. The light supplement modules will be placed under the seedbed, thus changing the dark situation of each link in the past. In order to solve the problem of poor plant growth caused by insufficient light in the seedling transition area, the original plan was to install appropriate fill light under the seedbed to solve this practical problem, they all gave up because there was not enough space under the seedbed, but now everything has become a reality with LED light sources. Not only can LED light sources be used to control plant growth in the transition area, but also the production is more flexible, there is no need to change the seedbed frequently. It is precisely because of this LED light supplement technology that the company has expanded its production area by 1200 m² square meters and is in good condition. Another 1800 m² square meters will also be installed in recent months. The LED light source can be easily installed on the existing sliding seedbed frame. The problem is that the LED light source will not start working until the plants are just in place, but this problem has been solved by computer programming. The test work is still in progress. The company's continuous experiments are to master the empirical data of large-scale use of LED light sources in the future. Originally, red and blue lamps were installed in the transition area to solve the problem of plant stretching, at present, if LED light source is selected for light supplement in the whole production process, it is necessary to consider selecting LED light source with multiple colors, and one of the major advantages of LED is that it can provide composite light source for plant growth needs. The results of the experiment are enough to convince me that LED can become the main light source to promote the growth of plants. I even think that there will be no need to add more greenhouses in the future. Due to the low cost of LED use, LED fill light technology will be widely used in the future, especially in today's increasingly expensive energy, just around the corner.
