一、良好水质的内容与要求1.水相平衡虾池一般正常的pH值为7.5～8.5;若pH在7.0以下或9.0以上就是有害的水质。池塘中溶解氧要求在5毫克/升以上。罗氏沼虾池一般要求氨氮不超过3毫克/升;亚硝酸盐不超过0.02毫克/升。磷酸盐是微生物和虾蟹生长的重要营养元素,而本地虾池往往缺乏,
First, the content and requirements of a good water quality 1. Aquatic balance Shrimp pool generally normal pH value of 7.5 to 8.5; if the pH below 7.0 or 9.0 is harmful to water quality. Dissolved oxygen in the pond requires 5 mg / l or more. Macrobrachium ponds generally require ammonia nitrogen does not exceed 3 mg / l; nitrite does not exceed 0.02 mg / l. Phosphate is an important nutrient for the growth of microorganisms and shrimp and crab, while local shrimp ponds often lack,
