%X The effects of different fertilizer application countermeasures on the soil NO3^--N accumulation in dryland maize were studied by the long-term located experiments. The results show that the different fertilizer application countermeasures can cause the soil NO3^--N accumulation in 0 - 500cm soft body in some degrees and have more effect on 0-300cm soil layer. The treatment of autumn fertilization with stubble mulch return is a perfect pattern for obtaining higher yield of corn in the semi-damp and drought areas of North China, can lower the soil NO3^--N accumulation and cause smaller danger to the environment.
