我们于2008-2010年进行了“水库生态养殖黄河口大闸蟹技术试验”。水库试验养殖黄河口大闸蟹面积40.63万亩,产蟹1831.50吨,实现总产值1.89亿元,利润1.16亿元。现将试验情况报告如下:一、条件与方法(一)试验条件1.水源水源主要为黄河水,黄河为地上悬河,无污染,水质优良,pH值8.0~8.3,属弱碱性水,总硬度2.16~5.56,属弱硬水,矿化度为0.2~0.6克/升,近几年年均引水量10亿米~3左右。黄河水通过引黄干渠
We carried out in 2008-2010 “Yellow River Estuary crab technology experiment ”. Reservoir test breeding Yellow River mouth hairy crab area of 40.63 hectares, producing 1831.50 tons of crabs, the output value of 189 million yuan, a profit of 116 million yuan. The test conditions are reported as follows: I. Conditions and Methods (I) Test conditions 1. The water source of the water source is mainly the Yellow River water. The Yellow River is a hanging river above the ground. No pollution and good water quality are obtained. The pH value is 8.0 to 8.3, The total hardness of 2.16 ~ 5.56, is a weak hard water, salinity 0.2 ~ 0.6 g / L, in recent years the average annual water diversion of 1 billion meters ~ 3 or so. Yellow River water through the main canal
