Table 1 Responses of soil physicochemical variables to shade treatment. Values are the means (SD) of six pot replicates. Different lowercase or capital letters indicate significant differences (P < 0.05, LSD test) in OJ (Ophiopogon japonicus, shade tolerant) or LP (Lolium perenne, shade-intolerant) soil. ***P < 0.001, **P < 0.01, *P < 0.05
