Abstract

To effectively reduce the effects of nitrogen pollutants on water environment. Selecting the rice-growing area of Liaohe River estuary in Panjin City of Liaoning Province as the research object, Different sections and the different stages of a single fertilization in ditch is sampled to measure and analyze the three nitrogen of ditch system in different stages of fertilization; the paper investigated the reductive variation of nitrogen concentration in paddy fields drainage. The results show that: Ammonia nitrogen concentration is on the decline in a whole, however, ammonia nitrogen was relaxedly increased in different periods, due to the variation of northern rice area is obvious in different stages of fertilization, fluctuations in paddy fields drainage on ammonia nitrogen. Nitrate nitrogen at the early stage of the basal period changes gently, after rising slowly towards stability. Nitrate nitrogen is decreasing along the way in Rice fertilizer period, but the trend is not obvious. At earing fertilizer period of Nitrate nitrogen is Firstly decline and then stabilize. The decision is ditches sediment microbial activity.
