为了透彻了解水中生物氮循环的机制,采用~(15)N示踪剂的技术在模拟的金鱼池中进行测量计算铵氮的代谢速度以及它在水中合成其他生物群落的营养物质和转化成其他含氮化合物的水平量。水中铵氮的转化速度非常高,估计是141％/小时。大部分铵氮被代谢转化成细菌和浮游植物 In order to provide a thorough understanding of the mechanism of biological nitrogen cycling in water, a ~ (15) N tracer technique was used to measure the rate of ammonium nitrogen metabolism in simulated goldfish ponds as well as its ability to synthesize nutrients in other biota in water and convert it to other The level of nitrogenous compounds. Ammonia conversion in water is very high, estimated at 141% / hour. Most ammonium nitrogen is metabolized into bacteria and phytoplankton
