图1 2021年干旱及复水处理对黄芪幼苗株高、根长、地上部和地下部生物量的影响 4、8、12分别代表短历时、中历时和长历时；P、D、R分别代表胁迫前、干旱胁迫和复水后。不同小写字母表示同一因素不同处理间差异达到显著水平（P < 5%）。下同。

Fig.1 Effects of drought and rehydration treatment on plant height, root length, aboveground and underground biomass of Astragalus seedling in 2021 4, 8 and 12 represent short duration, medium duration and long duration, respectively; P, D and R represent pre stress, drought stress and post rehydration, respectively. Different lowercase letters indicate that the difference among different treatments of the same factor reach a significant level (P < 5%). The same below.
