Chen Hong, director of Yongle Ring Reef Coral Protection: More than 30 years of related problems in coral reproduction

Over the years, Chen Hong, the director of the Yongle Reef Capture Protection of Yongle Reef Curgeons, and his team, in order to rescue and restore corals, the Global Environment Foundation of the United Nations Development Planning Department of the Global Environment Foundation of the Global Environment of Sanya Coral Transplantation and Monitoring Plan was undertaken. Participated in the National Oceanic Administration's "Ecological Survey of Coral Reefs and Sea Plants", "Swimming Biology and Screening Biological Surveys in Sanya Coral Reef Reserve", presided over Hainan Province's key and major scientific research projects ... For the current status of large -scale albinization of coral corals, the system, the system, system Study coral artificial breeding and transplant technology.

According to Chen Hong, since the establishment of the Hainan South China Sea Tropical Marine Research Institute (referred to as the "Hot Sea") in 2003, it has been conducting systematic research on local corals in Hainan. He has also been engaged in coral research for more than 30 years. A series of mature technologies have been developed by breeding, robotics auxiliary planting corals, and response to coral bleaching problems.

The large -scale reproduction of corals mainly uses the use of cell clusters to organize the cultivation of this non -breeding technical means. Chen Hong distinguishes it with coral branches and seedlings: It was originally a "coral seedlings", like the grandson monkey's seventy -two changes, blowing a monkey hair, a group of grandchildren's birth, the same way as the organization training method is the same as the organization training method is the same way. The reason, and the breeding of seedlings is planted one by one. Use this technology to cultivate corals to speed up the process of large -scale reproduction of corals.

Because there are many uncontrollable factors in the underwater operation, coral planting has always been difficult. At present, there are also many ways to plant corals, such as steel nail planting, cement planting, drilling planting, etc., which are generally selected according to the underwater conditions of various sea areas. At this stage, robots can be used to assist planting corals, but this also has special requirements for robots. It is necessary to consider the effects of waves, buoyancy, typhoons, etc. At present, this technology is constantly studying and exploration and improvement.

In addition, the cost of coral planting is high. According to many mature technical systems, it is estimated that it costs 1,000 to 2000 yuan to plant a "coral seedlings", and it can control it at 300-500 yuan through organizational training technology. Intelligent breeding corals, from cultivation, planting to monitoring, the entire set of complete chains can break through one by one, then this cost will continue to decline, and it may only cost a few yuan in the future.

The "China Coral Reef Status Report 2019" pointed out that China's coral reef resources are widely distributed, mainly distributed on the coast of South China, the coast of Taiwan and Hainan Island, and the Dongsha Islands, the Xisha Islands, Zhongsha Islands and the Nansha Islands. China has a high diversity of reef coral species. The total recorded reef coral species recorded in a total of 445 species of 2 groups and 77 groups, of which the reef coral species of the Nansha Islands are the highest. kind. Subsequently, there are 328 species of 16 subjects of 16 subjects; 297 and 251 species of Dongsha Islands and the Xisha Islands; 186, 82 and 114 species of Hainan Island, Guangxi and Guangdong coasts; 97 types; the diversity of reef coral species in Fujian Province is the lowest, and 7 are 7 genus.

Chen Hong said that based on the diversity of coral species, combined with morphological appraisal and molecular identification, it can accurately identify coral varieties. The team is constantly studying the conditions for exploring coral molecular identification to establish coral germs. If you can collect coral albums, including various forms of different coral species, and developing coral intelligent identification software, it will be greatly helpful for the appraisal of coral species.
