| Abstract: | The need for improving nitrogen use efficiency in rice production becomes more urgent.In the terms of genotypic differences in nitrogen use efficiency in rice,this study focused more on related to the morphological and physiological mechanisms.Moreover,we put forward present problems in the field,and prospected the co-ordination research of high nitrogen use efficiency and high grain yield in rice in the future. |
