一、做好虾池的前期准备,合理放养虾苗 青虾属底栖动物,耗氧量高,不耐低氧环境,游泳能力差,喜欢栖息于浅水区域、集群爬行于池边滩脚及维管束植物较多的地方。池塘面积2—4亩为宜,水源充足,水质清新,池水1—1.5m之间,坡比1:3,池底淤泥20cm,池底平坦,进排水安装密眼网袋。放虾前10天,虾池用生石灰(每亩100kg)清塘消毒,杀灭敌害生物。3天后注水50cm,施发酵粪肥(每亩100—200kg)培育浮游生物,为虾苗提供适口的天然饵料。7月中旬至8月初放苗,每亩放5—6万尾,规格为1—2cm。在放苗后20—30天,每亩投放100g左右鲢、鳙各30尾,用以调节水质。
First, do a good job in the shrimp pond preparation, rational stocking shrimp shrimp is a benthic animal, high oxygen consumption, impatience with hypoxia, poor swimming ability, like to inhabit shallow water areas, Vascular plants more places. Pond area of 2-4 acres is appropriate, adequate water, fresh water, water 1-1.5m, slope ratio of 1: 3, the bottom of the mud 20cm, flat bottom, the installation of dense mesh bags into the drain. Put the shrimp 10 days before, shrimp ponds with quicklime (100kg per acre) Qing Tong disinfection, killing enemy predators. 3 days after the injection of 50cm, the implementation of fermentation manure (100-200kg per acre) to plankton for shrimp to provide paternity natural food. Mid-July to early August Fangmiao, put 50000 per mu, specifications for the 1-2cm. 20-30 days after Fangmiao, put about 100g per acre silver carp, 鳙 30, to regulate the water quality.
