摘　　要：通过大田小区试验,在京山县对杂交水稻(Oryza sativa L.)品种扬两优6号进行了营养特性与施肥效应研究。结果表明,在氮、磷、钾养分之间,氮肥对该品种产量影响最大,其次是钾肥,磷肥对该品种产量影响不明显。综合而言,N、P2O5、K2O推荐经济施用量分别为200.0、95.0、165.0 kg/hm2。拔节孕穗期叶片SPAD值受施氮量影响较大,而与施磷量和施钾量无明显关系,该时期叶片SPAD值42.16可以作为该品种合理施氮的判断指标。Through field plot experiment,nutrition characteristics and the fertilizer effect for hybrid rice（Oryza sativa L.） Yangliangyou 6 in Jingshan were studied. The results showed that nitrogen fertilizer had the greatest impact on the yield, followed by potassium fertilizer,and the effects of phosphate fertilizer on the yield was not obvious. In General, fertilizer applied quantity in the actual production should be N 200 kg/hm2,P2O595 kg/hm2,K2 O 165 kg/hm2. Leaf SPAD values were significantly influenced by nitrogen application amount during jointing booting stage, and had no obvious relationship with phosphate and potassium fertilizer. Leaf SPAD value of 42.16 can be used as the indicator in rational application of nitrogen.
