自五十年代末建立海带育苗室以来,在育苗过程中经常发生一种幼体畸形病。这种病害在我国南方和北方的一些育苗室中或轻或重时有发现,严重时幼苗大量死亡,在生产上造成一定损失。例如,福建省连江县水产综合场为了改变每年从北方调运种海带的局面,从1971年开始实验在当地选育种海带。当海面水温升高时,把海带移到育苗室系统内人工控制低温培育。孢子囊形成后,采孢子进行常规育苗。这样采孢子时间比以往培育早秋苗要早一个多月,培育出来的幼苗个体大、健壮,适应能力强。但在实验过程中连续几年发生了较为严重的病害。因此,防治这种病害已成为我国南方海带养殖事业进一步发展的关键性问题之一。
Since the establishment of a kelp nursery room in the late 1950s, a larval orthopnea often occurs during nursery. This disease is found in some seedling raising rooms in the south and north of our country when it is light or heavy. In severe cases, the seedlings die in large quantities, causing some losses in production. For example, Fujian Lianjiang County Aquatic Comprehensive Field in order to change the annual transfer of kelp from the north situation, from 1971 experiments in the local breeding kelp. When the sea surface temperature rises, the kelp is moved to nursery room system artificial control of low temperature cultivation. After the formation of sporangia, spores were sporulated conventional breeding. This spore spore earlier than in the past to cultivate early autumn seedlings more than a month earlier, nurtured nursery individual large, robust, adaptable. However, in the course of the experiment for several years in a more serious disease. Therefore, the prevention and control of this disease has become one of the key issues for the further development of the kelp breeding in south China.
