Abstract: 【Objective】 In order to reveal the relations of leaf color and nitrogen uptake of rice. 【Method】 The dynamic change of upper-most three leaves color and nitrogen uptake rate of rice was studied in solution experiments. 【Result】 There were significant changes of leaves colors and nitrogen uptake during growing period. The three peaks emerged at the days after transplanting, 20 days before heading, and heading and anthesis, low vallies emerged at jointing stage and 10 days before heading. The rate of nitrogen uptake correlated closely with SPAD values of rice leaf after two weeks. 【Conclusion】 The dynamic change of leaf color of rice is mainly caused by nitrogen uptake of root, the changes of leaf color and nitrogen uptake rate are limited by inherent rhythm of its oneself, especially with constant nitrogen concentrations of solution.
