本文分析了裙带菜海上育苗产生的附着物问题,风浪对筏子的安全影响以及其他技术问题,因而提出了裙带菜育苗与海带相同的方向,以室内培育比较适宜,同时阐明了在室温条件下培育的原因。 实践的结果表明:1.室内水池育苗在每天的最大光强900～1000米烛,水温不超过海上温度,以过滤海水进行培养,裙带菜的配子体可以安全渡夏,秋后可以达到肉眼可见程度的幼苗,而基本不受附着物的危害;2.在水池环境育苗,竹皮比棕绳的育苗效果好,所以竹皮是裙带菜育苗的适宜生长基质;3.水池育苗的幼苗发生稠密,个体大,比海上育苗的幼苗发生量高20～128％。 我们对这一新的育苗法讨论了它的问题,并且认为:1.裙带菜的配子体有耐高温的性能,已为国内外的研究所证实,配子体于室内条件可以发育,也为斋藤报道过,因此配子体在水池渡夏并能培育出幼苗是可靠的。2.这种方法培育出的幼苗可以满足养殖嫩菜或成菜的要求,所以是一种有效的育苗方法。3.水池育苗比海上育苗安全,劳动条件好;比低温育苗成本低。由于水池育苗形式符合海藻培养业的专门经营;又因其技术简易又适于小型分散经营,这种育苗法比海上育苗和低温育苗在我国北方沿海更有广泛的应用价值。
In this paper, we analyzed the problem of attachments caused by sea nursery seedlings of Undaria pinnatifida and the safety impact of wind and waves on the rafts and other technical problems. Therefore, we proposed the same direction of nursery seedlings of seaweed and kelp, which is suitable for indoor cultivation. Meanwhile, s reason. The results show that: 1. indoor pool nursery maximum daily intensity of 900 ~ 1000 meters candle, the water temperature does not exceed the sea temperature to filter the sea water for culture, wapai gametophyte body can safely summer, autumn can reach the naked eye visible degree Of seedlings, and basically from the attachment of the hazards; 2 nursery environment in the pool environment, bamboo skin better than the brown rope nursery, so bamboo is suitable for growth of Undaria pinnatifida; 3 seedling nursery ponds dense, Individual large, seedlings than sea nursery high incidence of 20 to 128%. We discussed the issue of this new seedling raising law, and considered: 1. The gametophyte of Undaria pinnatifida has high temperature performance. It has been confirmed by the institutes both at home and abroad that the gametophyte can develop indoors and is also reported by Saito Therefore, it is reliable that the gametophyte breeds summer in the pond and can breed seedlings. 2. This method of nurturing seedlings to meet the requirements of breeding tender or into a dish, it is an effective nursery method. 3 pool nursery safer than sea nurseries, working conditions are good; low cost than low temperature nursery. Because of the nursery pool form in line with the seaweed cultivation industry specialized management, but also because of its technical simplicity and suitable for small-scale decentralized management, this nursery law than sea nursery and low temperature nursery in the northern coast of China is more widely used value.
