Abstract
The effects of the combined application of N, P, K and organic fertilizer on the yield formation and nitrogen uptake of hybrid rice Teyou 73 were studied. Test results showed that the tillering ability, leaf area index, dry matter accumulation and yield were improved by increasing the application of N, P and K fertilizer. The combined application of N, P and K fertilizer got the highest yield, and could promote N fertilizer absorption and transformation in rice plants. The rice yield was decreased by the supplement of organic fertilizer on the basis of the combined application of N, P and K fertilizer, because the applied N fertilizer was excess.关键词
