用人工养殖海带在我国还是一个新的尝试。1951年以前,只有山东和旅大沿海用国外传过来的,利用秋苗“绑苗投石”和“采孢子投石”等听天由命的方法,少量养殖,采用这种方法,因海带苗深沉海底,受光不足、生长期短,有的长得很小,甚至根本不长,海带产量少得可怜。这时,山东省水产生产部门职工和有关科研人员发现育苗用的竹筏子上,天然附生的海带发育得很好,就开始研究海带的生活习性,利用冷冻机和日光灯在室内进行低温育苗成功,并进行筏式和梯田养殖试验。试验的第一次,虽然增产不显著,但成活率已大为提高。1953年山东省水产养殖 Using artificial breeding kelp in our country is still a new attempt. Before 1951, only Shandong and Luda along the coast over the use of foreign countries, the use of autumn seedling “tied the seedling into the stone ” and “spore stone” and other methods of life, a small amount of breeding, using this method, Deep sea floor, lack of light, the growth period is short, and some grow very small, or not at all, kelp yield pitiful. At this time, Shandong Province, aquaculture production sector workers and researchers found that the rafts with seedlings, the natural epiphytic kelp developed well, began to study the living habits of kelp, the use of freezers and fluorescent light indoors successfully nursery , And raft and terrarium breeding experiments. The first test, although the yield is not significant, but the survival rate has been greatly improved. 1953 Shandong Province aquaculture
