| 中文摘要: |
| 通过连续3年的鼠尾藻生产性育苗试验，证明在北方海区提前育苗技术可行。该技术克服了鼠尾藻种苗繁育过程中难以培育出大苗的难题，通过提前50 d采苗，缩短室内培育周期，采用种菜人工促熟方法，结合室内及海上培育、管理的各种技术措施，得到的种苗健壮、均匀，整齐。共培育出鼠尾藻大规格苗种3 373.7万株，经海上中间培育3个多月后，幼苗直立枝数量3~4根、长度可达4-6 cm。 |
| 英文摘要: |
| A method for early production of large-size Sargassum thunbergii seedling in north China was developed, which consisted of procedures such as 50 d advancement of seed collection, timesaving of indoor cultivation and accelerated artificial maturation of broodstock thalli. This method should be used in combination with a set of off-shore mariculture and management techniqes. It is applicable in north China as proved by trials for three consecutive years. About 33.737 million healthy seedlings with uniform size were bred with this method, which grew into vertical young thalli (4~6 cm in length) with 3~4 branches after being cultured off shore for over three months. This method overcomes the difficulty of breeding large-size seedlings met in previous S. thunbergii seedling production practice, and will certainly facilitate the large scale seedling production and cultivation of S. thunbergii. |
