The application of nitrogen fertilizer can improve crop yield and economic benefits. However,improp-er nitrogen application may lead to reduced crop yield,resources wastage and a series of environmental problems. Therefore,how to improve flax seed yield and nitrogen fertilizer utilization efficiency at the same time is an important challenge in the producing process. This paper reviews the biological characteristics of oil flax regarding nitrogen de-mand,the effects of nitrogen application on flax growth,physiology and yield,the factors influencing nitrogen absorp-tion and utilization efficiency from agricultural measures,and summarize problems existing in the production. In addi-tion,the future research was expected to provide reference for improving nitrogen use efficiency of oil flax.
