应用案例
植物氮肥监测 全新氮肥指标-氮平衡指数NBI
氮平衡指数（NBI: Nitrogen Balance Index）是叶绿素（SFR）和类黄酮（FLAV）的比值：当未发生氮肥胁迫时，植物生长健康，合成叶绿素较多，产生的多酚（类黄酮）较少；当发生氮肥胁迫时，植物营养不平衡，产生的多酚（类黄酮）较多，生成叶绿素较少。传统方法通过叶绿素判断氮肥状况，当叶片叶绿素含量下降时（叶片变黄），说明植物缺失氮肥，在实际应用中，该方法有一定的延迟效应，叶绿素下降时几天甚至十几天前氮肥缺失的表现，即使此刻施肥，也会影响作物产量。而通过测量NBI值来评估氮肥状况时，避免传统方法中的延迟效应，叶绿素和多酚（类黄酮）稍有变化，即可检测出植物的氮肥状况，及时快速进行氮肥管理。
