水质好坏是对虾养殖成败的关键问题之一。水质恶化,有可能导致全军覆没。因此,人们常说的“养虾就是养水”是有道理的。 判断水质好坏,除了观察水色以外,经常测定水中某些物理化学因子的状况及其变化,也是非常重要的。这些因子包括pH、溶解氧(DO)、温度、盐度、H_2S、氨氮、硝基氮和亚硝基氮等。1989年我们对山东省沾化具某虾场养虾池中的pH,DO和H_2s等几项化学 Water quality is one of the key issues in the success or failure of shrimp farming. Deteriorating water quality may lead to annihilation in the army. Therefore, people often say that “raising shrimp is water” is justified. Judging the quality of water is good, in addition to observe the color of water, the determination of some physical and chemical factors in the water conditions and changes are also very important. These factors include pH, dissolved oxygen (DO), temperature, salinity, H 2 S, ammonia nitrogen, nitro nitrogen and nitroso nitrogen. In 1989, we analyzed the pH, DO and H 2 S in some shrimp ponds of a shrimp farm in Zhanhua, Shandong Province
