摘要
利用边坡较缓、淤泥较浅的2个池塘(共计3.3亩),通过人工设置水花生和网片附着物、投喂全价配合饲料、保持中度肥水等水质调节和病害防治措施,进行青虾养殖试验,结果亩产量 115.5 kg,亩利税 1709元,投入产出比 1:2.88。指出池水透明度应保持 30~40cm。
Chose the pond whose slope was slow ,and the bottom mud was shallow ,planted the water peanut and put the net as adhering substance, fed the shrimp with whole - value compound feed ,kept the water quality at medium fertility. As a result, the yield was 115. 5 kg/mu,the profit was 1 709 yuan/mu, the ratio of the input and the output was 1 2. 88. The experiment also proved that,the diaphaneity should kept at 30-40 cm.
