通过氮素调控对北方两个超级稻品种的叶绿素含量进行了分析。结果表明：施氮量越高，沈农265顶三叶的叶绿素含量越高，而铁粳7号则在中氮水平下更有优势。低氮和中氮条件下，前氮后移有利于沈农265齐穗后顶三叶叶绿素含量的增加，而高氮条件下，则出现相反作用；3个氮量水平下，前氮后移基本能够提高铁粳7号倒一叶的叶绿素含量，而倒二叶和倒三叶在中氮水平下占有优势。

The north two super rice cultivars chlorophyll content were analyzed under nitrogen regulation. The higher the nitrogen application,Shennong-265 top three leaves chlorophyll content were higher,while Tiejing-7 had more advantages in middle nitrogen levels. Shennong-265 chlorophyll content after heading increased under low and middle nitrogen and high nitrogen conditions had the opposite effect in nitrogen backwards. Nitrogen backwards can improve Tiejing-7 inverted leaf chlorophyll content,and only advantage in middle nitrogen levels for two and three leaves.
