池塘用罗茨鼓风机充气养虾,平均亩产250千克,平均规格13厘米,与非充气虾池相比,亩增产量100千克以上,投资与增益之比为1:9。现将充气养虾生产中的几项关键技术措施叙述如下: (一)充气设备的配备与安装 充气虾池选用送气量10立方米/分的罗茨鼓风机,可供20亩左右的虾池使用,配套动力为20～24马力柴油机或相应功率的电机。送气量为20立方米/分的罗茨鼓风机,可供40亩左右的虾 Ponds are inflated with Roots blowers to raise shrimp, yielding an average of 250 kg per mu and an average specification of 13 cm. Compared with non-aerated shrimp ponds, mu yields increased by more than 100 kg and the ratio of investment to profit was 1: 9. Now the inflatable shrimp production in the production of several key technical measures are described below: (a) inflatable equipment and installation of inflatable shrimp pond selection of air supply 10 cubic meters / min Roots blower for about 20 acres of shrimp pond use , Supporting power for 20 ~ 24 hp diesel engine or the corresponding power of the motor. Roots blower with 20 m3 / min capacity for about 40 acres of shrimp
