| Abstract: | This paper summarized the evaluation of nitrogen absorption and utilization efficiency of ryegrass,discussed the physiological process and molecular mechanism of nitrogen absorption and utilization by plants.The factors influencing nitrogen absorption and utilization efficiency of ryegrass were mainly discussed from soil factors,nitrogen fertilizer application,intercropping of ryegrass with other crops,genotypes of ryegrass cultivars,accumulation and distribution of carbon sources and endogenous hormones,and the future research was expected to provide guidance for improving nitrogen use efficiency of ryegrass by improving cultivation measures and molecular breeding,so as to realize the economic value of low investment and high yield. |
