Abstract：To seek the optimal water control mode for reducing the nitrogen and phosphorus losses, so as to achieve high yield, pollution reduction, and water saving, the effect of nitrogen and phosphorus losses in winter wheat was studied by different field groundwater table controls. The results show that different water control patterns had an obvious effect on nitrogen and phosphorus concentration in winter wheat. Through the control of underground water, ammonium nitrogen(NH+4-N)in underground drainage at different growth stages of winter wheat was decreased, but the nitrate nitrogen(NO-3-N)was increased.Total phosphorus(TP)concentration of water treatment with the water level of 100mm kept increasing at the jointing-booting stage and kept decreasing at the heading-flowering stage, while that with the water level of-200 mm kept decreasing at the jointing-booting stage, but kept increasing at the heading-flowering stage. Soil available nitrogen content of winter wheat was reduced at the jointing-booting stage. Maintaining high water level at the heading-flowering stage was conducive to reducing the available nitrogen content. Available phosphorus content at the jointing-booting stage in soil was reduced to a certain extent. Maintaining high water level at the heading-flowering stage can reduce the available phosphorus content. At the lower water level, the longer the water control time was, the greater the available phosphorus content was.
