LED lamp irradiation promotes coral growth

According to reports, in addition to viewing, corals with bright colors were also used for medical purposes such as bone transplantation. However, due to the slow growth of corals and serious piracy problems, the number is scarce, therefore, it is difficult to obtain materials. Zhongzheng University optical and electrical? ? Ding chuzhen, an associate professor at the Institute of Integrated Engineering, studied the rapid propagation technology of corals and used different LED lights to make the growth of hard bone corals more than 10 times faster. Ding Chuji found that the nutrients that promote coral growth mainly come from symbiotic algae in the body, and symbiotic algae need different light at different growth stages. For example, yellow light and green light are needed for light cooperation, but splitting must rely on blue light stimulation. Therefore, he used artificial cultivation to continuously irradiate LED or OLED lights 24 hours a day, and adjusted the wavelength and brightness of the lights, successfully accelerating the growth rate of hard bone corals by more than 10 times, at the same time, artificial cultivation can also eliminate the risk that wild collection may contain bacteria. In addition, corals have high requirements for water quality. Ding Chuji has created a marine-like environment for this purpose, continuously detects the concentration of trace elements such as calcium, magnesium and strontium, and adjusts the color temperature controller of LED lamps. It is estimated that the market scale of hard bone coral materials will reach 3. 4 billion US dollars in 2017. Ding Chuji not only applied for various patents for this coral cultivation technology, but also signed a three-year production and study cooperation with Taiwan biotechnology company, and technology transfer, the future is expected to make bone transplantation and dental implants more convenient.
