Result Richards Model and Monodic Quadratic Equation could properly describe grain dry matter growing process and the change process of grain filling rate with days after anthesis. There was big difference in average grain filling rate, maximum grain filling rate under different planting density. Average grain filling rate 1.26 mg/ and maximum grain filling rate 2.44 mg/ of T7 were the quickest, and the average grain filling rate 0.94 mg/ and maximum grain filling rate 1.99 mg/ of T12 were the slowest, and the maximum difference percentage of the average grain filling rate and maximum grain filling rate among different density were 33.98%, 22.61%. There was significant correlation between average grain filling rate, maximum grain filling rate, grain filling active duration, rapid increasing stage and thousand grain weight, and the correlation coefficients were 0.628*, 0.630*, 0.849**, 0.739**. Active grain filling duration contributed mostly to TGW.
