近年来,紫菜丝状体培育方式的探讨是国内外藻类学者研究的重点内容之一。1962年日本藻类学家岩崎英雄研究不用贝壳培育紫菜苗(即自由丝状体)获得成动,这一培育方式目前已被应用于生产,但因存在:(1)容易污染,对种菜的处理和水质的要求难度较大;(2)藻丝自由生活,游离成团互相遮挡,未能充分利用水体和光照;(3)壳孢子的集中放散较难进行等问题,所以至今依然无法普遍被生产者所接受。为进一步改变紫菜丝状体原有的生活方式为固着的生活方式,1977—1979年,我们试验把紫菜丝状体自由的生活方式改为固着的生活方式,即让丝状体固定在某一基质上生长发育,简称为固着丝状体。现将这一培育方式的试验报告如下:
In recent years, the study on the cultivation of laver filaments is one of the key contents of algae scholars at home and abroad. In 1962, the Japanese algaeman Iwasaki heroic study obtained the formation of seaweed seedling (ie, free filamentous body) without shell cultivation. This cultivation method has been applied to the production at present, but because of the following reasons: (1) easy to pollute, Handling and water quality are more difficult; (2) the algal filaments are free to live and the free litter blocks each other, and the water and light are not fully utilized; (3) the concentrated release of the conchospores is difficult to be carried out and so is still not universal Accepted by the producer. In order to further change the original way of life of seaweed filaments as a fixed way of life, from 1977 to 1979, we tried to change the free-living way of seaweed filaments into a fixed way of life, Growth and development on the substrate, referred to as fixation of filaments. Now this cultivation method of test report is as follows:
