Abstract: A field experiment was conducted to access the fertilizer efficiency of bulk-blended fertilizers （BB fertilizer1#, 6#and 7#） on rice. The results showed that all the three bulk-blended fertilizers （BB fertilizer1#, 6#and 7#） were suitable to apply on rice, and if the application of net nitrogen was 18kg/667m^2,meanwhile applying BB fertilizer 7# as base fertilizer, whose reagent ration was N：P：K=30：12：10cl,both the yield and the investment efficiency would be highest.
