越冬池塘越冬池塘面积3300米2左右,池塘深度必须达2.0～2.5米,有效水深达1.2～1.8米、浮游植物生物量在25～50毫克/升的范围内较合适。只要渗漏不严重,有效水深1米以上的池塘均可作为生物增氧越冬池。越冬前要清塘,清除池底污泥,或将池水排干,晾晒3～7天,用生石灰浆全池泼洒。
Winter ponds overwintering pond area of 3300 m 2, the depth of the pond must reach 2.0 to 2.5 m, the effective water depth of 1.2 to 1.8 m, phytoplankton biomass in the range of 25 to 50 mg / l more appropriate. As long as the leakage is not serious, the effective depth of 1 meter above the pond can be used as bio-oxygen overwintering pool. To clear the pond before winter, clear the bottom of the sludge, or drain the water, drying 3 to 7 days, with a full lime splashing lime slurry.
