多元素缓释营养粒在海带育苗生产中的应用试验

Experiment of Using Polyelement Slow-distributed Nutrient Pellet in Seed Culture of Laminaria

１９９９年７～１０月在威海市崮山综合育苗场海带育苗生产中进行了多元素缓释营养粒的应用试验。结果：６ ０００ ｍ２育苗水面共出苗 ６亿株，一类苗出苗率 １００％。证明在大规模工厂化海带育苗生产中，用这种含有多种微量元素的可控生态型肥源代替普通化肥是可行的。

During July to October of 1999,the experiment of applying polyelement slow- distributed nutrient pellet in the seed culture of Laminaria was carried out. The result showed that, of the 6 000 square metre pond, 0. 6 billion seeds were obtained,all of which was first rate. The experiment proved that,in the production of large sized industrial seed culture of Laminaria, use the new typed controllable ecological fertilizer instead of the common chemical fertilizer was practical.
