图7 生物积累量与形态特征（a）和营养元素吸收量（b）的相关性分析 WPDW：整株干重；ADW：地上部干重；RDW：根系干重；PH：株高；MRL：最大根长；TRL：总根长；SA：根表面积；AD：平均根直径；RV：根体积；各元素化学符号表示其吸收量。“*”表示相关性达显著水平（P < 0.05），“**”表示相关性达极显著水平（P < 0.01）。

Fig.7 Correlation analysis between biomass accumulation and morphological characteristics (a) and nutrient element absorption (b) WPDW: whole plant dry weight; ADW: aboveground dry weight; RDW: root dry weight; PH: plant height; MRL: maximum root length; TRL: total root length; SA: root surface area; AD: average root diameter; RV: root volume; the chemical symbol of each element indicates its absorption.“*”indicates significant correlation (P < 0.05); “**”indicates extremely significant correlation (P < 0.01).
