the circulating water system circulates water 8 times per day, an ozone generator with the input amount of 50g/h is started for 10 eight hours per day, and the average ORP value is kept to be 245 through an ORP automatic monitoring system 43;

s5: illumination management: a single-layer transparent plastic film and a single-layer black gauze are adopted to wrap the seaweed farm ceiling, so that the light intensity required by growth of the bracken and the dunaliella is met;

s6: and (3) pest killing management: regularly putting tea seed cakes into the culture pond for killing insects, wherein the putting amount of the tea seed cakes is 15 kg/per mu per meter of water depth, putting quicklime while putting the tea seed cakes, the putting amount of the quicklime is 10 kg/per mu per meter of water depth, and tea saponin contained in the tea seed cakes is used as hemolytic toxin and can melt erythrocytes of animals so as to kill aquatic insects in seaweed;

s7: and (3) management of the algae cage 2: open back side lid 3 through the buckle, put into algae cage 2 with the slope of algae frame 1 that has cultivated the marine alga to through the draw-in groove 26 that the both sides were equipped with in the algae cage 2 with algae frame 1 fix in algae cage 2, place algae cage 2 at the bottom of breeding pond 4 again, the pond is inhaled every day to the diver, clears up incomplete bait and pond are dirty.

According to the invention, the bracken and the feathered algae are cultured by the algae frame, and the algae frame is placed in the algae cage in the green sea turtle culture pond after the culture is finished, on one hand, the grid design of the algae cage enables the green sea turtles to eat the algae extending out of gaps of the algae cage, on the other hand, the algae in the algae cage is protected from being eaten by the green sea turtles, the growth sustainability of the bracken and the feathered algae is ensured, and the green sea turtles are used as a landscape after the edible value of the green sea turtles is provided, so that a good appearance effect is provided for the artificial breeding field of the green sea turtles.
