Nitrogen is one of the important nutrient elements of crops,and plays an important role in the growth,quality and yield of crops.In recent years,the application of nitrogen fertilizer significantly increased the yield of wheat,however,the irrational application of nitrogen fertilizer in wheat production had resulted in a large number of nitrogen loss,environmental pollution and lower nitrogen use efficiency.In order to reduce environmental pollution,improve nitrogen utilization efficiency,effects of nitrogen fertilizer on key enzyme activities in nitrogen metabolism and reuse in wheat,contents of free amino acids and soluble proteins in nitrogen assimilates,accumulation and distribution of dry matter and nitrogen,yield characters and yield and nitrogen use efficiency were reviewed.The results showed that the amount of nitrogen fertilizer for wheat in China was about 240 kg·hm~(-2),and reasonable suggestions were put forward for the application of nitrogen fertilizer.
