Objective] Study on the 3414 fertilizer effect test of rice. [Method] Three factors and four levels of N,P,K were applied in the experiment. [Result] The best rational recommended dosage were 591 kg/hm2 of Nitrogen, 375 kg/hm2 of Phosphorus and 105 kg/hm2 Potassium fertilizer. The optimum proportion was 233. [Conclusion] The cultivation measures of rice should be insist in the principles of proper Nitrogen, Phosphorus decreasing and Potassium increasing.
