海带人工育苗工作是发展海带栽培事业的一个重要环节,在人工控制的循环海水系统中,确保大量密集海带幼苗的正常生长乃是一项复杂的任务,其中病害问题尤为重要。近年来,全国不少育苗单位在育苗过程中普遍发生脱苗和烂苗现象,时常影响正常供苗。在严重的情况下,可以发展成为毁灭性灾难,甚至使整个育苗工作完全失败,往往因为苗源不足给海带栽培事业的发展带来损失。本研究工作的前两篇报告阐述了褐藻酸降解菌是海带藻体上的主要定居者和优势菌群,即使在不附加任何其他营养的条件下,这
The artificial breeding of kelp is an important step in the development of kelp cultivation. Ensuring the normal growth of a large number of dense kelp seedlings in a manually controlled circulating seawater system is a complicated task, of which the disease problem is particularly important. In recent years, many nursery units throughout the country in the process of nursery emergence of seedlings and rotten seedlings phenomenon, often affect the normal supply of seedlings. In severe cases, it can develop into a catastrophic catastrophe and even cause a complete failure of the nursery. It is often because of lack of seedling that the loss of the development of kelp cultivation causes. The first two reports in this work show that alginic acid-degrading bacteria are the major settlers and dominant microflora on kelp, even without any additional nutrients
