The N(nitrogenous) and P(phosphorous) release were analyzed every two days.[Result] At the prophase, the N release in B was bigger than that in A, while the decline sediment release in A was gentle.[Conclusion] There was no accumulation of organic compound during the breeding time. The NH4-N was the main form of N release; and the P release was correlated with N release, while PO4-P was the main form of P release.展开更多
MAX 锦鲤场(Max Koi Farm)窗外的雨渐渐停了,西斜的太阳破云而出,我们一边听着叶金春先生讲解有关新加坡龙鱼场的故事,一边欣赏路边的热带风光。车驶向了下一站——MAX 锦鲤场。大巴驶进 MAX 锦鲤场时,我们不敢相信是到了龙鱼场,鱼场围...MAX 锦鲤场(Max Koi Farm)窗外的雨渐渐停了,西斜的太阳破云而出,我们一边听着叶金春先生讲解有关新加坡龙鱼场的故事,一边欣赏路边的热带风光。车驶向了下一站——MAX 锦鲤场。大巴驶进 MAX 锦鲤场时,我们不敢相信是到了龙鱼场,鱼场围墙上飘着印有各种锦鲤鱼的彩旗,活动广场的一面墙上,从东到西,满满排着各种锦鲤比赛的奖杯。展开更多
