With different fertilization, the photosynthetic rate of rice was measured, then the distribution and yield components were analyzed to investigate the influences of single mycorrhizal fertilizer and the mycorrhizal fertilizer mixed chemical fertilizer on rice yield. The results showed that: 1) The usage of single mycorrhizal fertilizer increased the storage capacity and the photosynthetic rate of rice, making rice yield increase by 2927％, while there was no difference in distribution of dry matters. 2) The photosynthetic rate of rice was improved by the mycorrhizal nitrogen fertilizer, moreover， the proportion of dry matter to the rice seeds raised, and rice yield increased by 4137％. 3) The photosynthetic rate of rice was enhanced by the mycorrhizal phosphate fertilizer and the mycorrhizal nitrogen and phosphate fertilizer; there was no difference in distribution of rice dry matter; the rice yield increased by 1910％ and 1748％, respectively. The usage of single mycorrhizal fertilizer and the mycorrhizal nitrogen fertilizer can effectively improve the rice yield, but it needs further research to touch the effectiveness of the other fertilizer-modes.
