对池塘养鱼而言,修筑池堤若材料选择不当,池堤防水性能不好而常漏水渗水;这不仅培不好水质养不好鱼,同时对新建场站影响到整体生产的合理布局;特别是山区,池堤材料的合理选择显得更为重要;为此,这里介绍几种较实用的池堤材料选择方法。一、一般材料的选择既要就地取材方便,又要实用节约资金;如在山区石灰岩较多的地方,可选择以石灰岩为主,石灰黄泥混合土为核心墙的池堤砌筑方法,即池堤两边用20～40厘米的浆砌块石,中央用10～20厘米的石灰黄泥混合土填
For pond fish farming, the construction of the bank should be improperly selected if the materials are not properly selected and the water quality of the bank is poor. However, it is not only difficult to cultivate the poor quality of the fish but also affect the rational layout of the whole production. Especially in the mountainous area, the reasonable choice of pool embankment materials is even more important; for this reason, several practical methods of pool embankment materials selection are introduced here. First, the choice of general materials should not only take convenient materials on the spot, but also practical to save money; such as limestone in mountainous areas, you can choose to limestone-based, mixed with lime-clay as the core wall of the pool embankment construction method, That is, on both sides of the pond embankment with 20 to 40 cm of masonry stone, the central 10 to 20 cm of lime mixed with mud fill
