Abstract: This paper reports the study results on holding culture of sporeling and cultivation technique of \%Laminaria longissima\% Mayabe in sea water zone on the basis of the indoor culture and sporeling rearing As shown below,the sporeling 2 0 cm in length coming out of culture tank early in October can reach 30 cm through holding culture for a month A water temperature of 19～15℃, the earlier the seedling comes out of nursery pool for holding culture,the faster the seedling grows, the shorter the time is for holding culture of seedling The sporeling of seed transplantation early in November can grow up to adult plant 10 2 m in length and 40 cm in width throug cultivition for six months in Dalian sea water zone, which displays the fine characteristics of large adult seaweed, fast growth, wide adaptation of temperature and late maturation The optimum cultivation depth and spacing in the rows of \%Laminaria longissima\% Mayabe are 1 5 m and 15 cm respectively The earlier the seed separation,the higher the output from the first of November to the tenth of december
