池塘混养青虾与池塘的生态环境密切相关,控制好池塘生态环境条件是提高养虾产量的关键。近年来,我们在推广池塘混养青虾工作中,采取了一些科学的措施和方法,有效地提高了青虾的成活率,取得了较好的经济效益。现将实践中探索的经验总结如下,供参考。1、池塘清整 冬捕后或青虾放养前,将池水彻底排干,清除过多的淤泥,底层淤泥厚度不超过10cm,先让池底曝晒1～2周,淤泥干涸后再用生石灰和硫酸铜全池泼洒,彻底杀灭池塘中的病菌,寄生虫及卵、有害藻类、青苔和杂草,为鱼虾健康养殖打下良好基础。
Pond polyculture of freshwater shrimp ponds and ponds are closely related to the ecological environment, controlling the ecological environment of ponds is to raise the key to shrimp production. In recent years, we have adopted a number of scientific measures and methods in the promotion of polyculture of freshwater prawns in ponds, which effectively improves the survival rate of freshwater shrimp and achieves good economic benefits. Now the experience of exploration in practice are summarized below for reference. 1, clear the pond after winter fishing or freshwater shrimp before stocking, the water drained thoroughly, remove excess sludge, the bottom of the sludge thickness of not more than 10cm, let the bottom of the pool exposure for 1 to 2 weeks after the sludge dry lime and then Copper sulfate Quanchiposa, completely kill pond bacteria, parasites and eggs, harmful algae, moss and weeds, lay a good foundation for the healthy cultivation of fish and shrimp.
