| 图4 2021年毛乌素沙地黑沙蒿、赖草单位质量叶片氮含量和光合氮利用效率季节动态(平均值±标准差)。横向参照线为各参数观测期内均值, B中黑色虚线是赖草叶片氮利用效率的趋势拟合线。 |
| Fig. 4 Seasonal dynamics of leaf nitrogen content per unit mass (Nmass) and photosynthetic nitrogen use efficiency (PNUE) of Artemisia ordosica and Leymus secalinus in Mau Us Sandy Land in 2021 (mean ± SD). The horizontal lines represent the mean values. The black dashed line in B is a trend-fit line for PNUE of L. secalinus. |
