Soil samples were labeled as Table 2. S1, CK1-Single peanut, S2, CK2-Single buckwheat, S3, CK3-Single sorghum, S4,CK4-Single glutinous millet, S5, Intercropping buckwheat(/peanut), S6, Intercropping peanut(/buckwheat), S7, Intercropping glutinous millet(/peanut), S8, Intercropping peanut(/glutinous millet), S9, Intercropping peanut(/foxtail millet), S10, Intercropping sorghum(/peanut). Indices of all soil samples from two cropping systems were compared by using Duncan's multiple comparison. Significant differences were observed among all soil samples (P<0.05).
