水稻氮素的生物学特性及其高产运筹研究概况

A Review of the Nitrogen on Biological Characteristics and Its High Produce Management in Rice

本文着重对氮素营养与水稻生育特性、氮素与水稻群体的产量形成、氮素的吸收及其利用、水稻氮素高产运筹技术等进行了阐述,并提出了水稻氮素在栽培学与育种学研究上需要深入研究的几个方面,以其为今后水稻大面积生产上氮素的高效利用提供依据。

The article compares on the relation between the nitrogen and the characteristics of growth and yield formation in rice.The nitrogen absorption and utilzation and high produce nitrogen management in rice were expatiated.Meanwhile, Some topics on the nitrogen in rice for the application were brought forward for the time to come to previde basics for the efficient nitrogen uptake and utilization in rice on the line crop to planting.
