[0020] Using the raft culture technology of shellfish and algae commonly used in the prior art, in the eutrophic sea area of Qingdao Jiaozhou Bay (the sea area near the estuary of the Haibo River), the eutrophication environment restoration test was carried out from 2003 to 2004 in the sea area. The water temperature is 2-27°C. The cultivation mode of the macroalgae is as follows. From the beginning of May, 2003, Gracilaria lemaneiformis was cultivated. The asparagus used comes from the coast of Kamata, Fujian. Cultivate asparagus by clamping seedlings hanging method, each rope clips 1 meter of seedlings, 16-18 clusters of seedlings, each cluster of seedlings is 13-15 cm long, and 0.1 kg of seedlings per rope. The asparagus is 1 to 2 meters above the water surface, and it falls and falls. The distance between the rafts is 4 meters. 400 ropes of asparagus are cultivated per mu. Started to cultivate 2 mu, and by the beginning of July, the planting scale was expanded to 10 ...
