To improve nitrogen utilization and reduce the loss of nitrogen during maize growing periods，a field experiment was conducted. We evaluated the effects of different nitrogen forms on dry matter accumulation，nitrogen absorption and utilization，yield of maize and soil nitrogen under the same rate of nitrogen application with the basis of farmers’ habitual application of amide urea. Five treatments were set up in this experiment:without nitrogen fertilizer(CK)，amide nitrogen fertilizer(T1)，ammonium nitrogen fertilizer(T2)，nitrate nitrogen fertilizer(T3)and nitrate/ammonium nitrogen fertilizer(T4). Results showed that:(1)The dry matter accumulation and nitrogen accumulation of maize differed among the treatments at maturity，i.e.，T4>T3>T1>T2>CK. The dry matter accumulation and nitrogen accumulation of T4 were significantly increased by 6.3%～15.0% and 6.4%～30.1%，respectively，compared with those of other nitrogen treatments. This treatment prolonged the period of peak dry matter and nitrogen accumulation in maize and delayed the moment of the maximum accumulation rate of dry matter and nitrogen in maize.(2)Compared with T1 and T2，the soil nitrogen dependence rate and the apparent nitrogen loss of T4 decreased by 10.9%～23.1% and 12.8%～49.1%，respectively. For the whole growing period，soil nitrate nitrogen content in nitrogen treatment was significantly higher than the ammonium nitrogen content. The decreasing extent of soil nitrate nitrogen content was higher than that of ammonium nitrogen under all treatments.(3)The nitrogen use efficiency，nitrogen production efficiency，nitrogen agronomy efficiency and yield of maize in T4 were higher than those of other nitrogen treatments，and increased by 6.8%～25.9%，7.3%～14.4%，21.3%～48.3% and 7.3%～14.4%，respectively. Therefore，compared with farmers’ conventional application of urea，the combined application of nitrate/ammonium nitrogen fertilizer can increase maize yield and nitrogen utilization，reduce nitrogen loss in Heilonggang，Hebei province.
