图2. 植物茎秆和叶片磷(P)含量的时间动态。A, 龙蒿。B, 糙隐子草。C, 狭叶沙参。D, 广布野豌豆。E, 达乌里芯芭。F, 阿尔泰狗娃花。G, 麻花头。H, 羊草。I, 披针叶野决明。J, 冷蒿。K, 瓣蕊唐松草。圆形代表植物叶片; 三角形代表植物茎秆。实线表示叶片P含量与采样时间相关性显著(p < 0.05); 虚线表示茎秆中P含量与采样时间相关性显著(p < 0.05)。
Fig. 2. Temporal variation of phosphorus (P) content in leaves and culms. A, Artemisia dracunculus. B, Cleistogenes squarrosa. C, Adenophora gmelinii. D, Vicia cracca. E, Cymbaria daurica. F, Aster altaicus. G, Klasea centauroides. H, Leymus chinensis. I, Thermopsis lanceolata. J, Artemisia frigida. K, Thalictrum petaloideum. Circle, leaves; triangle, culms. The solid line indicates that leaf P content is related to sampling time (p < 0.05); The dotted line indicates that culm P content is related to sampling time (p < 0.05).
