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3.0g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。

关 键 词:草莓  SPAD-502型  叶绿素计  叶绿素含量  叶片  含氮量  施氮量

Abstract: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.
Keywords:strawberry  SPAD-502 chlorophyll-meter  chlorophyll content  nitrogen content
