水是渔业生产的物质基础,及时加水、排水,调节水质是池塘稳产、高产,提高经济效益的重要措施之一,所以降低水的费用,即可降低养殖生产成本。1 合理选择场址 选择场址首先必须有水源保障。除土质不渗水,治安状况良好和光照充足外,最好在天然河边,要求大水不淹,小水能灌,尽可能排灌自流。若选址不当,尽管各方面条件都具备,干旱时远离水源,进、排水时全靠电力机械,按水深2.5m计算,在降雨量和蒸发量持平时,1亩池塘加水耗电计算方法为: MgH=n·J[kw·h]
Water is the material basis for fishery production. Adding water, draining water and regulating water quality in time is one of the important measures to stabilize the production of high-yielding ponds and increase economic efficiency. Therefore, reducing the cost of water can reduce the cost of aquaculture production. A reasonable choice of site selection site must first have water protection. In addition to soil impermeable water, law and order in good condition and adequate sunshine, the best in the natural riverside, requiring flood flooding, irrigation of small water, drainage and drainage as possible. If the location is not appropriate, despite all the conditions are available, the drought away from the water, into the drainage of electricity thanks to the whole machinery, according to a depth of 2.5m calculation, rainfall and evaporation in a flat, 1 mu of pond water consumption is calculated as : MgH = n · J [kw · h]
