裙带菜海上育苗试验报告

裙带菜(Undaria pinnatifida)是一种比较大型的经济海藻,在我国的辽宁、山东沿海和浙江的舟山群岛等都有自然繁殖。它的营养成分,除碘和碳水化合物外,其它部分均高于海带。另外,裙带菜还是一种碱性最高的藻类,这种碱性物质对人体健康有密切的关系,它可以中和人体内部因疲劳和新陈代谢

A REPORT ON THE SPORELINGS BREEDING EXPERIMENT OF THE Undarla pinnatifida (Harv.) SUR.

This experiment was done on 23rd, July, 1982-12th, Oct., 1982, on the raft in the scallop culture area of Shi-miao Sporelings Breeding Farm of Dalian Fisheries CultureCompany. The breeding of the sporelings of Undarla pinnatifida (Harv.) Sur. in Sea have many advantages: little investment, lower production cost, and higher efficiency. It is a better method of sporelings breeding nowadays. The suitable date for sporelings collecting is from the last part of June to the last part of July, or to the first part of August. The most suitable density of seedling collection is 150-200 zoospores per visible field (100×). If the seedlings breeding ropes are used directly for cultivation, the suitable density will be 50 zoospores per visible field (100×). Fertilizer cannot be applied in the sea area with 6-10m transparency, containing N 40-50 (±) mg per m³, P 10 (±) mg per m³, and least floating soil and other sea-weeds. The most suitable breeding depth is 2-3m. The seedlings breeding ropes may be washed or brushed in about every 8 days.
