不同磷酸盐对草鱼种生长影响的研究

Optimization research of different phosphate for grass carp Ctenopharyngoden idella

选用5种磷酸盐分别进行草鱼种饲养实验，其结果以草鱼成活率、增重率和饲料系数三项指标为依据进行综合分析，结果表明：磷酸二氢钠、磷酸二氢钙和磷酸二氢钾是草鱼较好的磷源，其次是磷酸二氢铵，磷酸氢钙的效果相对较差。

Feeds including five kinds of phosphate respectively were used to optimize for grass carp seeds. A synthetically analysis were carried out according the three quotes of survival rate, weight gain rate and feed efficiency. The results were that NaH2PO4, Ca（ H2PO4 ）2 and KH2PO4 were the relatively perfect phosphate resource, Secondly was NH4H2PO4, effect of CaHPO4 was relatively poor.
