池养青虾的关键技术是调控好水质,重点是处理好肥水与浮头的关系。青虾的摄食演变规律是,从摄食浮游生物逐步过渡为底栖食性,从滤食性逐步转变为捕食习性。因此要做到“肥水养幼虾,清水喂中虾”。2月份池塘底质的肥瘦在池边四周挖坑堆肥,随着温度的逐渐升高,水位的逐步加高,发酵腐熟的粪肥自然溶人池中。3～4月份若池水中浮游生物量不足。池水透明度在40厘米以上,应及时追施发酵粪肥水50～100公斤/亩。4月中下旬一般已有抱卵虾出现,同时由于日 The key technology of pond raising shrimp is to regulate and control the water quality, and the key point is to handle the relationship between fertilizer and floating head. The evolution of freshwater shrimp feeding is gradual transition from feeding plankton to benthic habitat, gradually changing from filter-feeding to predation habits. Therefore, to be “fat water raising shrimp, shrimp feed water.” February pond sediment fat and thin around the pond ditching composting, with the gradual rise in temperature, the water level gradually increased fermentation of manure dissolved composting pool of natural. 3 ~ April if the pond water plankton lack of biomass. Water transparency of 40 cm or more, should be topdressing manure fermentation water 50 to 100 kg / acre. In mid and late April generally have shrimp emergence, at the same time as the day
