摘要
研究采用南美白对虾塑料大棚保温三级淡化暂养技术等措施,实现南美白对虾池塘双茬淡化养殖。养成期间水质情况良好,水温平均(26±3)℃,pH值约8.5左右,溶氧量5.6mg/L以上,氨氮约0.20mg/L,亚硝酸氮0.02mg/L左右,每667m2养殖产量达426.7kg,养殖效益高达4186.7元。结果表明,采用南美白对虾双茬淡化养殖技术,延长了对虾生长期,提高了池塘利用率和经济效益,具有较好的推广价值。
At present, different farming moclels were explored actively by scientists for the traditional single-crop fanning has not adapting the needs of efficiency with the continuous improvement of farming technology on Penaeus vannamei. The following study combined three-desalination farming technology to plastic shed insulation to stock fries as extending shrimp season to increase pro- duction and efficiency. The water quality was good during shrimp forming. Results from the count data analysis of three samples of farm operators demonstrated that the average water temperature was 26±3℃, pH 8.5 , DO 5.6 mg/L, Ammonia-N 0.20 mg/L, and ni- trite-N 0.02 mg/L.The yield of farming was 426.7kg and the efficiency was 4186.7 RMB. Therefore, using double-crop farming models improved both the utilization of the pond and efficiency.
