为探索对虾养殖高产技术,实现养虾高产量、大规格、高效益。日照市自1989年进行罗茨鼓风机充气养虾试验,当年在17亩虾池中,收获对虾3900公斤,平均亩产230公斤,平均规格达13厘米以上。1991年,开始推广应用,1992年又进行了大面积推广,全市应用充气虾池由1991年的1处40亩迅速增加到59处1800亩,充气虾池平均亩产对虾250公斤,亩效益达3600元,与非充气虾池相比,亩增产量100公斤以上,亩增效益2000多元。现就该市充气养虾生产及技术应用方面的一些问题论述如下:
In order to explore the shrimp farming high-yielding technology, shrimp production to achieve high yield, large size, high efficiency. Rizhao City since 1989, Roots blower aerated shrimp test, when 17 acres of shrimp ponds, 3900 kilograms of prawn harvest, the average per mu 230 kg, an average of more than 13 cm. In 1991, popularization and application began. In 1992, a large-scale popularization was carried out. The city’s inflatable shrimp ponds increased rapidly from 40 acres in 1991 to 1,800 acres at 59 spots. The average inflatable shrimp ponds produced 250 kg shrimp per mu, 3600 yuan, compared with the non-inflatable shrimp ponds, acres by more than 100 kilograms, more than 2,000 yuan benefit by increasing acres. Now on the city of aerated shrimp production and technical application of some of the issues discussed below:
