江蓠是一种重要的经济海藻,是制造琼胶的主要原料之一。1945年澳大利亚首次用江蓠提取了琼胶,年产量达20吨。1959年我国广东省人工养殖的江蓠亩产干品达250至350斤。自七十年代以后,国外对江蓠的研究有了很大的进展。我国的台湾省人工养殖的江蓠每公倾产量已达10吨。由于台湾的自然条件较好,资源也比较丰富,有适于进行营养繁殖的种类,所以以营养繁殖的方法进行了大面积的人工养殖。
Gracilaria is an important economic seaweed, is one of the main raw materials for the manufacture of agar. In 1945, Australia first extracted agar with Gracilaria, with an annual output of 20 tons. In 1959, our country’s Guangdong Province artificial breeding Jiang 蓠 mu produce dry goods up to 250 to 350 pounds. Since the seventies, great progress has been made in the study of Jiang Ze in foreign countries. China’s Taiwan Province, the artificial breeding Jiang 蓠 per-capita yield has reached 10 tons. Because of its natural conditions, abundant resources and suitable species for vegetative reproduction, Taiwan conducted large-scale artificial breeding by means of vegetative propagation.
