摘　　要：研究了氮、磷、钾、有机肥配施对杂交稻特优73产量形成与氮吸收的影响。结果表明:增施氮、磷、钾肥都能提高水稻的分蘖能力、叶面积指数和干物质积累量,从而提高产量。以配施氮磷钾肥的水稻产量最高;在配施氮磷钾肥的基础上增施有机肥,因为氮肥偏多,产量有所下降。氮、磷、钾肥配施,能促进水稻对氮肥的吸收与转化。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.
