塑料大棚具有采光、升温、保暖的作用,在不启动锅炉的情况下,冬季可通过蓄水池和培育间2级塑料大棚采集太阳光能,来提升池水温度进行稚参室内越冬保苗。有深海水井的地区可结合提取井水调兑自然海水的保苗方式或从潮间带海水井直接抽提井水的方式进行。历经5个月塑料大棚室内越冬保苗,稚参增重1.7～2.6倍,成活率可达90％,比室外虾池保苗成活率约高35％。
Plastic greenhouses have the function of lighting, warming and keeping warm. Without starting the boiler, the solar energy can be collected in the level 2 plastic greenhouse in the winter by the reservoir to raise the temperature of the pond water to protect the seedlings in the winter. Areas with deep-sea wells may be combined with safeguards to extract well water for natural seawater or direct well water from inter-tidal seawater wells. After five months of indoor plastic shed winter over the seedling, juvenile weight gain of 1.7 to 2.6 times, the survival rate of up to 90%, than the outdoor shrimp pond seedling survival rate of about 35%.
