图1. 内蒙古大针茅草原6种植物叶凋落物和根分解过程中的质量剩余率变化(平均值±标准误, n = 3)。A, 叶凋落物分解。B, 根系分解。由于银灰旋花叶片较小且易碎, 第76天处理时出现较大异常。

Fig. 1. Variation of mass residual rate during the decomposition process of leaf litters and roots of six plant species in Stipa grandis steppe in Nei Mongol (mean ± SE, n = 3). A, Decomposition of leaf litters. B, Decomposition of roots. Because Convolvulus ammannii leaves were small and fragile, and a big abnormality appeared at 76 daysʼ treatment.
