图5 光谱指数与叶片氮累积量的关系 LNA为叶片氮累积量。a: 苗期; b: 块茎形成期; c: 全生育时期。**表示在0.01水平上显著差异。

Fig. 5 Relationship between spectral index and leaf nitrogen accumulation LNA is the leaf nitrogen accumulation. a: seedling stage; b: tuber formation stage; c: total growth stages. ** indicates significant difference at the 0.01 probability level.
