In order to evaluate accurately the condition of dry matter production characteristics of rice varieties in different accumulated temperature zones in Heilongjiang Province, 32 representative rice varieties were selected and studied. The results showed that total stem material production in the early stage were: the 2nd accumulated temperature zone > the 3rd accumulated temperature zone > the 1st accumulated temperature zone > the 4th accumulated temperature zone; and in the late stage were: the 3rd accumulated temperature zone > the 1st accumulated temperature zone > the 2nd accumulated temperature zone > the 4th accumulated temperature zone. The dry matter production of the rice varieties in each plot was different in early stage, but entered the late stage the spike dry matter distribution rate were: the 3rd accumulated temperature zone （59.88%）> the 1st accumulated temperature zone （59.33%）> the 2nd accumulated temperature zone > the 4th accumulated temperature zone, there were no difference between these 1st and 3rd temperate zones, but significantly higher than other temperature zone. The dry matter exportation and transformation rate is far greater than the apparent transportation rate of rice varieties in Heilongjiang Province, therefore, it should be mainly focus on the distribution and transportation of dry matter in the late stage to improve the yield of rice varieties.
