通过观察在饲料中添加磷酸二氢钾对中国对虾仔虾存活率、体长增长率及仔虾体内含磷量的影响,探索了仔虾对磷的需要量。研究表明,添加磷酸二氢钾使饲料中磷含量为1.16%～1.37%时,仔虾的体长增长率最佳。饲料中磷含量在0.71%～1.82%的范围内,对仔虾的存活率、体内的磷含量无显著的影响
By observing the effects of adding potassium dihydrogen phosphate in feed on the survival rate, body length growth rate and phosphorus content in larvae of Penaeus chinensis, we explored the phosphorus requirement of larvae. Studies have shown that adding potassium dihydrogen phosphate feed phosphorus content of 1.16% to 1.37%, larval body length growth rate of the best. The phosphorus content in the feed ranged from 0.71% to 1.82%, which had no significant effect on the survival rate of larvae and the content of phosphorus in the body
