摘　　要：试验共设7组,第1组用井水+食盐,第2~6组Ca^2+、Mg^2+、K^+浓度分别为92~138、26~300、13~138 mg/L,同时每组再设2个平行试验组,对照组(第7组)为当地河口水,Ca^2+、Mg^2+、K^+浓度分别为200.4、502.0和152.0 mg/L。结果表明:水体中Ca^2+和Mg^2+浓度对南美白对虾幼虾生长效果与饲养效果有显著影响(P<0.05)。南美白对虾成活率主要受K^+浓度的影响,试验结果存在显著差异(P<0.05)。Seven groups were used,well water+salt was used in the first group,the concentrations of Ca^2+,Mg^2+,K^+used in the second-sixth groups were 92-138,26-300 and 13-138 mg/L respectively,and two parallels were set in each group.The control group(the seventh group)was the local river mouth,and the concentrations of Ca^2+,Mg^2+,K^+were 200.4,502.0 and 152.0 mg/L.The results showed that the concentrations of Ca^2+and Mg^2+respectively in the water had significant influences on the growth effect and feeding effect of Penaeus vannamei larvae(P<0.05).The survival rate of P.vannamei was mainly affected by K^+concentration,and the experimental results showed significant differences(P<0.05).
