  1. Note: The first letter in the code represents sandy types (A, fixed sandy land; B, semi-fixed sandy land; C, shifting sandy land) and the second letter in the code represents the plant species (C, bulk soil without plant; N, N. tangutorum; H, H. ammodendron). Values are means of three replicates, and means in the column followed by different letters are significantly different (P < 0.05). The statistical differences in data are statistically analyzed by the least-significant difference test (P < 0.05) using SPSS version 17.0 for Windows (SPSS Inc., Chicago, USA)
