An efficiency trial of N, P and K fertilizer on rice growth was carried out by ‘3414’ experimental design. The results showed that Fertility of soil on rice yield contribution rate is 71.0%. 12.5 kg fertilizer N, P2O5 4.2 kg and 8 kg K2O per 667m2, and N, P2O5, K2O ratio of l∶0.34∶0.64, which was the highest yield and fertilizer efficiency best.
