| Abstract: | Based on the field experiments of six levels of nitrogen fertilizer in winter wheat, the effects of N fertilizer on the content of soil NO3--N remained and the corresponding relationship between it and the space distribution of winter wheat roots were studied, at the same time, the trend law of the content of soil NO3--N and amount of nitrogen fertilizer was explored. besides, the cause of formation and the most dangerous stage of nitrogen fertilizer resulting in polluting ground- water were also studied in this paper. |
