随着农业产业结构调整的深入,一些沿江沿湖地区为了保护生态,开始“退田还湖”,改种稻为养蟹。为此,2000年至2001年我们在湖北省监利县周城垸渔场匡湖开展了利用低湖田(低洼稻田)进行大面积河蟹养殖实验,取得了较好的经济效益和生态效益,养殖技术路线基本成熟。 一、湖田的选择 低湖田是在“以粮为纲”的年代围湖造田形成的农田,其地势低洼,易形成积水。因此,在选择低湖田进行养蟹时必须注意以下几点:一要水源充沛,水质良好无污染,进排水方便,旱可灌,涝可排;二要低湖田的底质为硬沙泥 With the deepening of the adjustment of agricultural industrial structure, some of the coastal areas along the lake in order to protect the ecology, began to “return farmland to the lake”, to change rice for crabs. Therefore, from 2000 to 2001, we conducted large-scale crab farming experiments using low lake fields (low-lying paddy fields) in Marina of Zhoucheng Embankment, Jianli County, Hubei Province, and achieved good economic and ecological benefits. The breeding technology route Basic mature. First, the choice of Hu Tian Hu Tian low in the “grain as the key link” in the formation of farmland around the lake, its low lying, easy to form water. Therefore, the choice of low lake for crabs must pay attention to the following points: First, to abundant water, good water quality and pollution-free, easy access to drainage, drought irrigation, waterlogging row;
