临界氮浓度稀释模型在牧草种子生产中的应用前景

Application Prospect of Critical Nitrogen Concentration Dilution Model in Grass Seed Production

氮素是影响牧草种子产量的关键因素,氮素对于植株分蘖、干物质生产、花序形成、产量组分动态变化等均具有影响。文章主要从临界氮浓度稀释模型的概念、构建方法、研究现状、应用等方面进行了综述,提出临界氮浓度稀释模型在实际生产中应用时存在的问题,并对其在牧草种子生产中的应用前景进行了展望。

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 forma- tion 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 ex- isting problems of its application in practical production were put forwarded. Finally, the application pros- pect of critical nitrogen concentration dilution model in the grass seed production were also prospected.
