Field experiments were conducted to investigate effects of different fertilizer synergists on rice yield and fertilizer uti-lization rate in southern hilly areas. The results showed that the number of effective spikes increased by 0. 9 ~ 2. 1 and the number of grain increased by 3. 4 ~ 10. 6 per panicle, under the same rate of fertilizer with addition of fertilizer synergist ( DCD, HQ, NAM, ANO, PASP) . Accordingly, the production of rice increased obviously by 3. 51% ~ 6. 15%. In ad-dition, the effect of dicyandiamide on rice yield was the most effective, the yield reached 7 982. 8 kg/hm2 . Furthermore, fer-tilizer synergist effectively increased the nutrient accumulation of rice and improved the fertilizer utilization ratio. The fertilizer utilization ratio of N and K in dicyandiamide treatment was the highest, which was 64. 21% and 48. 45% respectively. Utiliza-tion rate of P fertilizer in dicyandiamide treatment was 24. 67%, which was ranked only second to that of hydroquinone treat-ment. In conclusion, fertilizer utilization ratio of N, P and K were increased by 2. 29% ~ 8. 44%, 3. 91% ~ 7. 40%, and 2. 90% ~ 8. 72%, respectively with application of fertilizer synergist.
