【摘要】 <正> 用现行的海带夏苗培育法,自采孢子到培育成1—3公分的幼苗,约70天就够了。因当时海面水温尚未降到19℃以下,不适于幼苗生长,不能出库下海,必须在育苗库中再“多培育”一段时间。在我国,愈是南方,其“多培育期”愈长,例如在福建省就要“多培育”120天。而现行育苗库中的培育条件又不能满足幼苗在“多培育期”继续健康旺盛地大量生长,所以采孢子后,用较弱光强,较低温度等方法抑制生长,以防止幼苗生长过速过大。达样不仅成本高,管理麻烦,甚至导致幼苗罹病腐烂,脱苗烂苗。更多还原

【Abstract】 In this paper. we report a modified method on the cultivation of Haidai by summering; young sporophytes. This modified process may be divided into three periods. The first period is cultivation of gametophytes, the second period is storage of gametophytes at low temperature (0°-2℃) in dark condition and standing sea water without changing, the thirdperiod is cultivation of sporelings. This modified method has some advantages, economic in operature and fertilizers, improving the laboring conditions and so on.The rot disease of Laminaria summer sporelings is also discussed.更多还原
