摘要
中原地区4月初引进盐度为15‰P5南美白对虾高盐度虾苗进入温室淡化标粗30~35 d,虾苗达到3~5 cm后在5月中旬投放外塘,经过60 d养殖规格达到50~70头/kg,用地笼捕出上市;6月初在温室内进行第二茬育苗,经淡化标粗到4~6 cm后投放外塘,在9月中旬10月初清塘上市,实现南美白对虾中原地区一年两茬外塘养殖模式。
At the beginning of April,the high-salinity shrimp seedlings of Penaeus vannamei with salinity of 15‰P5 were introduced into the greenhouse to desalinate for 30-35 days.After the shrimp seedlings reached 3-5 cm,they were put into the outer pond in the middle of May.After 60 days of cultivation,the specification reached 50-70 head/kg,and were caught in the land cage for listing;At the beginning of June,the second crop of seedlings was raised in the greenhouse,which was desalinated to 4-6 cm thick and then put into the outer pond,and the pond was cleared from the middle of September to the beginning of October,so as to realize the cultivation mode of two crops of Penaeus vannamei in the outer pond in the Central Plains.
