Table 2 Soil property indicators of sample plots. S is Slope (o),BD is soil bulk density(g/cm3), OM is organic matter(g/kg), SD is soil particle density(g/cm3), CD is electrical conductivity(ds/m), WS is water-soluble salt content(g/kg), MC is microbial carbon(mg/kg), P1 is > 2 mm soil particle content(%), P2 is < 0.002 mm soil Particle content(%). O is bare slope, B is Prunella vulgaris combined with earthworm planting slope, A is Single planting prunella vulgaris slope.
