去年9月,在水陆相接的大连金州区路海村传出一件奇事:个体养虾户张贵友养殖的对虾亩产260公斤,平均虾长12.7厘米,达到国家出口一级标准,收入12万元,而其它养虾户亩产只有140公斤,最大的虾不过9厘米。养虾户们纷纷前来取经。张贵友的答案出人意料地简单,他没有什么高超的技术,只是喂虾的 In September last year, a miracle happened in Luhai Village, Jinzhou District, Dalian, which was connected by land and water: Individual shrimp farmers Zhang Guiyou produced 260 kilograms of shrimp per mu, with an average shrimp length of 12.7 centimeters. 120,000 yuan, while other shrimp farming households only have 140 kilograms, and the largest shrimp is only 9 centimeters. Shrimp farmers have come to learn. Zhang Guiyou’s answer is surprisingly simple. He does not have superb skills but he only feeds shrimp.
