Abstract: A “3414” fertilizer efficiency test on meddle-season rice Guangliangyou 676 was carried out. The results showed that under the experimental conditions, the effect of fertilization was nitrogenous fertilizer > phosphorous fertilizer > potash fertilizer; the highest yield of meddle-season rice was 8 661 kg·hm^-2 while the application of N, P₂O₅ and K₂O was 259 kg·hm^-2, 91 kg·hm^-2 and 183 kg·hm^-2 respectively, and the economic benefit was the best with a yield of 8 570 kg·hm^-2 while the application of N, P₂O₅, K₂O was 214 kg·hm^-2, 75 kg·hm^-2, and 149 kg·hm^-2 respectively.
