Abstract
With the summer maize as material and by field experiment,the nitrogen real-time monitoring technology was constructed based on the soil nitrate nitrogen test and nitrogen balance to increase the maize yield and the nitrogen use efficiency.The research indicated that the optimum application of nitrogen fertilizer was 183~280 kg/hm2 with the average of 220 kg/hm2,which could save 45.3% nitrogen fertilizer,but increase the maize yield by 4.1%.the verification test showed that the yield of the optimized nitrogen fertilization treatment was the highest.As a result,the application of the optimized nitrogen fertilization determined in this experiment was reasonable,which could decrease the application rate of nitrogen fertilizer and loss of nitrogen,then increased the nitrogen use efficiency.
