图4 不同龄级黑沙蒿枝干性状沿不同降雨处理的变化。不同大写字母表示不同龄级的枝干性状差异显著（P<0.05）；不同小写字母表示不同降雨处理的茎性状差异显著（P<0.05）；*，P<0.05；**，P<0.01；***，P<0.001；ns（non-significant），不显著

Fig.4 Characteristics of changes in twig traits of Artemisia ordosica of different ages at different rainfall treatments. Different uppercase letters indicate significant differences of twig traits between different ages within the same rainfall treatment at P<0.05level. Different lowercase letters indicate significant differences of twig traits between different rainfall treatments within the same ages at P<0.05 level. *， P<0.05； **， P<0.01； ***， P<0.001； ns （non-significant）， not significant
