| 摘 要： | 本文对2008年9月中旬以来福建省坛紫菜养殖发生大面积烂苗情况进行调查和原因分析，一是受到秋季气候异常，持续高温影响坛紫菜生长发育；二是海区养殖密度过大，养殖筏架人为设置密度过高，导致海水交换不畅，引发烂苗症的加剧；三是壳孢子苗帘附苗密度过高，坛紫菜的种质老化，遭遇不良环境时抗病害能力弱；四是受台风影响，局部海洋生态环境短期内发生变化。为此作者及时提出防病害技术措施和对策，为今后坛紫菜的生产发展作参考。

| Abstract: | In the middle of September in 2008,a large scale of the cultured porphyra haitanensis has became rotten in Fujian province.The investigation result and reason analysis were studied in this paper.At first,the abnormal autumn weather especially the continuous high temperature affects the growth of porphyra haitanensis;secondly,the density of cultivation in sea area is too great,and the rafts density is artificially set too high,which result poor sea water exchange and trigger more severe rotten phenomenon;thi... |
