應用案例
植物氮肥監測 全新氮肥指標-氮平衡指數NBI
氮平衡指數（NBI: Nitrogen Balance Index）是葉綠素（SFR）和類黃酮（FLAV）的比值：當未發生氮肥脅迫時，植物生長健康，合成葉綠素較多，產生的多酚（類黃酮）較少；當發生氮肥脅迫時，植物營養不平衡，產生的多酚（類黃酮）較多，生成葉綠素較少。傳統方法通過葉綠素判斷氮肥狀況，當葉片葉綠素含量下降時（葉片變黃），說明植物缺失氮肥，在實際應用中，該方法有一定的延遲效應，葉綠素下降時幾天甚至十幾天前氮肥缺失的表現，即使此刻施肥，也會影響作物的最終產量。而通過測量NBI值來評估氮肥狀況時，避免傳統方法中的延遲效應，葉綠素和多酚（類黃酮）稍有變化，即可檢測出植物的氮肥狀況，及時快速進行氮肥管理。
