| 摘 要： | 进行了氮肥不同施肥方法对超高产水稻品种"沈农265"主要生理性状的研究。试验结果表明:"沈农265"最佳施肥方法为施肥法A;CGR、NAR均与叶片叶绿素含量呈正相关;SLW与叶片含氮量呈显著正相关;在5个主要生育期叶氮、叶碳、叶绿素含量的最适值均与产量存在回归关系。 |

| Abstract: | Effects of nitrogen application methods on main physiological characters in super-high-yield rice variety Shennong 265 were studied in 2006.The results showed that under this experimental conditions,method A of applying nitrogenous fertilizer is the optimum for rice Shennong 265;CGR,NAR and chlorophyll contents in leaves had positive relations;the optimum contents of nitrogen,carbon and chlorophyll in leaves at five main growth stages had regressive relations with yields. |
