An experiment was conducted at Qingtongxia Municipality Seed Breeding Farm using the field plot experiment and"3414" test plan to research the effects of different dosages and proportions of nitrogen, phosphorus and potassium fertilizers on the rice yield components, yield and economic benefit. The results showed that the reasonable ratio of N, P and K could increase the yield of rice by 8.69%~77.41%, of which the yield with the treatment of ⑥N2P2K2 was the highest as 8 271 kg/hm2, an increase by 77.41%. In combination with the local practical experiences in the agricultural production and fertilizer application, the recommended fertilization quantities for the rice growing on the soil type are pure N 217.7~242.0 kg/hm2, P2O5 61.5~98.8 kg/hm2 and K2O 52.2~95.7 kg/hm2.
