摘　　要：探讨了草莓叶片叶绿素含量、含氮量及不同施氮量与SPAD值之间的关系。结果表明 ,草莓叶片叶绿素含量、含氮量与SPAD值显著相关 ,当每盆施氮量为 3.0 g尿素时 ,SPAD值增幅最显著 ,为 48.8% ,最佳施氮量为每盆 3.0g尿素。The relationships between SPAD readings and the contents of chlorophyll and nitrogen in strawberry leaves and varied N applications were researched. Results showed that there was a significant correlation between SPAD readings and the contents of chlorophyll and nitrogen in strawberry leaves and that the optimum nitrogen application was 3.0 g urea per pot.
