采用田间试验的方法，利用15N同位素示踪技术，研究了施氮对龙粳31和空育131两个水稻品种15N吸收与分配的影响。试验结果表明：植株生长前期水稻吸收的氮素的量最高；水稻籽粒中的15N累积分配量龙粳31高于空育131，而在茎秆龙粳31低于空育131；水稻吸收的氮在植株体内的重新分配和转运效率对龙粳31的产量增加有重要作用。

In field experiments, the effect of nitrogen application on 15N absorption and distribution of Longjing 31 and Kongyu 131 rice varieties was studied by 15N isotopic trace technique. The results showed that nitrogen absorbed by rice plant is the most in the early plant growth, and 15N accumulation of Longjing 31 grains are higher than Kongyu 131, but stem organ is the opposite; the real ocation and trans-fer efficiency of nitrogen absorbed by rice have an important role to the increasing of Longjing 31 output.
