Method and device for increasing growth speed of hermatypic coral

The invention relates to the technical field of coral cultivation, and particularly discloses a method and device for increasing growth speed of hermatypic coral. The method for increasing the growth speed of the hermatypic coral includes the steps that reactive metal is arranged close to a growth sea area of the hermatypic coral and is subjected to electrochemical corrosion in seawater to release electrons, and the concentration of carbanions in the sea water in the area is improved to accelerate growth of the hermatypic coral. The method has the advantages that the fact that the reactive metal magnalium will be subjected to electrochemical corrosion in the sea water is used, the concentration of carbanions in the sea water environment is increased, and growth of the hermatypic coral can be accelerated greatly. In addition, the device is convenient to manufacture, transport and set, low in manufacturing cost and suitable for practical ecological work, can be arranged into different shapes according to the te
