在进行坛紫菜(Porphyra haitanensis)全人工采苗之前,为了促使壳孢子集中大量放散,目前生产上采用的是“下海刺激法”。“下海刺激法”就是在采苗的前一天,将成熟的贝壳丝状体,装入由聚氯乙烯绳编制的刺激网袋内,挂下海经海水冲击一夜,于次日晨六点前挑回放入室内采苗池里,壳孢子便集中大量放散出来。该法效果好,已被广泛应用于生产实践。但尚存在:操作麻烦、需要劳力
Before the whole plantation of Porphyra haitanensis seedlings was taken, in order to promote the massive release of conchospores, the production method of “sea-floor stimulation” was adopted at present. “The sea to stimulate the law ” is the day before the mining seedlings, the mature shell filaments, loaded with PVC rope prepared by the stimulation net bag, hang the sea by seawater impact overnight at 6 am the next day Back pick back into the indoor mining seedling pool, a large number of conchospores are concentrated out. The law is effective and has been widely used in production practice. But it still exists: the operation is troublesome and requires labor
