Keyword:  循环流水流水池蓄水池立体开发模式生长发育水中浮游生物肥料培育生态系统盐都县病害防治;
Abstract: 循环流水高效优化立体开发养殖,是应用生态学原理组合的以鱼为主、鱼蚌菱藕等多元生产、闭合循环的养殖系统,是理想的高效优化立体开发模式,现结合盐都县生产实践,介绍其技术要点,供参考。1科学建池鱼池结构是由蓄水池、流水池、二级池塘、三级河蚌地、四级水生植物池5个生态系统,用循环流水作媒介联络。蓄水地要建在地势较高位置上,以水泥和砖头做材料,长短与流水池组相齐;二级池塘最好利用原有池塘,宽度与流水池组相同,长度根据条件灵活掌握,比例最好是667m2面积流水池,配制0.53~0.67hm2二级池塘,塘底为斜坡状,水深2m左右。三级地为河蚌吊养他,主要是为增加综合收益而设。四级池是菱、藕种植地,其作用是净
