摘要
本文介绍了利用黄河三角洲地区丰富、闲置的重盐碱地,经过合理调配水质,在反复试验的基础上设计出一套合理的健康养殖技术方案,实施了大面积南美白对虾盐碱地健康养殖。尤其是通过在用盐碱地渗出的咸水与淡水混合调配成的,盐度为5~20的养殖用水中,添加一定浓度的钾离子,有效提高了虾苗的成活率。
In the Huang He river delta,there were large proportion of saline-alkali area,which was non-occupied.We managed to use it to culture southern American prawn and succeeded .Mixing the vadosed brackish water with fresh water, adding ion potassium to the mixed water whose salinity was 5-20,could effectively improved the survival rate of the larvae.Ponds with a total area of 7 949 mu was stocked with the larvae of the prawn,the unit yield was 157 kg/mu,the average size of the harvested prawn was 12.09 cm.
