| Abstract: | In the peak period of N-requirement in the growing period, the amount of nitrogen fixation was only 1/5 of that required by the soybean. The leaf surface tracer with 15N-urea showed that the urea nitrogen could be transfered into N-storage efficiently and rapidly. The production, demonstrated that N-application on the leaf surface could relax the supplying-demanding relation in soybean flowering period. |

| Keywords: | N-urea tracer nitrogen fixation relative growing speed. |
