从我国紫菜养殖的发展历史可以看出,苗种供应是一个非常重要的问题,我国主要的养殖海藻品种,无论是海带还是裙带菜,都是解决了苗种问题之后才发展起来的。目前,由于紫菜养殖存在许多种苗技术中的不合理现象,大量缺苗、烂苗的情况时有发生,从20世纪60年代沿用至今的育苗技术的不完善性又长期得不到解决,同时苗种生产越来越分散的现代体制,都是造成紫菜养殖中苗种生产不稳定性的主要原因。 It can be seen from the history of the development of seaweed farming in our country that the supply of seedling is a very important issue. The main types of cultured seaweed in China, whether kelp or wakame, are developed after the seedling problem was solved. At present, due to the unreasonable phenomenon of many kinds of seedling technology in seaweed farming, the situation of large numbers of seedlings and rotten seedlings often occurs. The imperfectness of seedling technology which has been in use since the 1960s has not been solved for a long time. Meanwhile, The modern system in which seed production is more and more dispersed is the main reason for the instability of seed production in laver farming.
