| Abstract: |
| The effect of appeyling nitrogen fertilizer to north spring rice was studied by using15N tracer in field micro-plot on the absorption,distribution and uti- lization of the nitrogen by the rice plants during the different nitrogen applying levels so as to provide the theotilizer basis for the scientifie fertilizer applica- ting. |
| Key words: 15N-tracer technology the nitrogen effect of rice(O.sativa L.Keng) |
