1、使用氯化锰5、10、20、50、100、200ppm浓度处理海带苗,以低浓度5、10、20、50ppm浓度处理对海带的生长有阴显的促进作用,最适浓度为20ppm,高浓度100、200ppm对海带生长有抑制作用、对碳含量、氮含量和磷含量也是以20ppm处理效果最明显。 2、使用20ppm锰处时,以30分钟效果较好,超过60分钟和低于30分钟对海带生长效果不如30分钟明显。 3、使用20ppm锰,以不同次数处理的结果是 2—6次效果明显,增重都可达到10％以上。 4、EDTA~(-4)M与20ppm锰混合浸泡处理,对海带生长的促进作用稍有影响。
1, the use of manganese chloride 5,10,20,50,100,200 ppm concentration of kelp seedlings treated with low concentrations of 5,10,20,50 ppm concentration of kelp growth had a significant role in promoting the optimum concentration of 20ppm , High concentrations of 100,200ppm inhibited the growth of kelp, the carbon content, nitrogen content and phosphorus content is also the most obvious 20ppm treatment. 2, the use of 20ppm manganese at 30 minutes better, more than 60 minutes and less than 30 minutes on the kelp growth less effective than 30 minutes. 3, the use of 20ppm manganese, treated with different times the result is 2-6 times obvious effect, weight gain can reach more than 10%. 4, EDTA ~ (-4) M mixed with 20ppm manganese soaking treatment, the promotion of kelp growth slightly affected.
