| Abstract: | Nitrogen is one of the key nutritional elements to determine the level of grass seed yields. The additional nitrogen supplying is beneficial for plant tillering, dry matter production, inflorescence formation and the dynamic changes of the yield components. In this paper, the conception, methods, research status and the application of critical nitrogen concentration dilution model have been reviewed, and the existing problems of its application in practical production were put forwarded. Finally, the application prospect of critical nitrogen concentration dilution model in the grass seed production were also prospected. |
| Keywords: | Grass seed Nitrogen Critical nitrogen concentration Critical nitrogen dilution curve Dilution model |
