本文进行了温度对室内培养的鼠尾藻生长的影响试验,结果表明室内培养时15℃鼠尾藻长度增长最快,但藻体鲜重均有不同程度的减少。海上养殖时鼠尾藻长度增加最快时的温度是15～16℃,而鲜藻湿质量在各试验温度下都快速增加,特别是次生分枝长出后湿质量增加最快。本试验在最适宜的生长温度下(5～7月)进行海上养殖试验,鼠尾藻日平均增重率比在常规养殖期(3～7月)提高了5倍。
In this paper, the effect of temperature on the growth of Sargassum fuscus was studied in laboratory. The results showed that the growth of Sargassum was the fastest at 15 ℃, while the fresh weight of the algal was decreased to some extent. The maximum temperature of seaweed when the length increase is 15 ~ 16 ℃, while the wet algae wet quality increases rapidly at each test temperature, especially when the secondary branches grow wet mass increases fastest. In this experiment, the marine culture experiment was conducted at the most suitable growth temperature (May-July), and the average daily rate of increase of Sargassum was 5 times higher than that of the conventional culture period (March-July).
